So I'm working on a list of bonsai styles for a personal project. I compiled this list from wikipedia but I feel like it is lacking. What is missing?

EnglishJapaneseDescription
Formal upright(Chokkan)The tree has a straight, upright, tapering trunk. Branches progress regularly from the thickest and broadest at the bottom to the finest and shortest at the top. This gives the branches a triangular shape and symmetry which is sought after for a formal upright style. There should be strong surface roots visible, moving from the base of the trunk downward into the soil, and radiating evenly around the trunk (preferably with none pointing directly toward the viewer).
Informal upright(Moyogi, takichi)The trunk and branches incorporate visible curves, but the apex, or tip, of the tree is located directly above the trunk's entry into the soil line. Similar to the formal upright style, branches progress regularly from largest at the bottom to smallest at the top, although this progression may be broken where the irregular shape of the trunk would make a branch abnormally prominent or obscure.
Slanting(Shakan)The trunk is straight like that of a bonsai grown in the formal upright style. However, the slant style trunk emerges from the soil at an angle, and the apex of the bonsai will be located to the left or right of the root base. Branches will generally parallel the ground, rather than growing at right angles to the slanted trunk.
Cascade(Kengai)Modeled after trees that grow from banks over water or down the side of a mountain. The apex of a (full) cascade style falls below the base of the pot. To give scope for the cascade shape, this style often appears in a tall, slender container not used elsewhere in bonsai.
Semi-cascade(Han-kengai)The apex of the tree extends just at the level of, or beneath, the lip of the bonsai pot. It does not fall below the bottom of the pot.
Multi-trunk cascade(Takan-kengai)This style applies to any cascade style in which two or more trunks cascade downwards.
Split-trunk, hollow trunk(Sabamiki)This style portrays the visual effect of a lightning strike or other severe and deep trunk damage, which has been weathered over time. It is applicable to deciduous species, conifers, and broadleaf evergreens. The hollowed trunk is usually chiseled, making a hollow that can range in size from a shallow scar to nearly the full depth of the trunk.
Driftwood(Sharimiki)This style portrays a tree with a significant part of its trunk bare of bark. In nature, trees in the sharimiki style are created by disease, physical damage to the trunk, weathering, and age. At least one strip of live bark must connect the leaves and living branches to the root system to transport water and nutrients. The bared trunk areas give a strong impression of age regardless of the tree's conformation, so driftwood bonsai often fall outside of the conventional styles in shape and foliage.
Exposed-root(Neagari)The roots of the tree are exposed as extensions of the trunk, free from soil. The roots can extend as far as one-half to two-thirds the total tree height.
Root-over-rock(Sekijoju)The tree's roots are wrapped around a rock. The rock is at the base of the trunk, with the roots exposed to varying degrees as they traverse the rock and then descend into the soil below.
Clinging-to-a-rock(Ishizuke, ishitsuki)The roots of the tree grow in soil contained within the cracks and holes of the rock. The rock may serve as a simple container, with the tree escaping the container and forming its own shape, or the tree may show a closer relationship to the rock's shape, growing close to the rock and following its contours.
Twin-trunk, two-trunk(Sokan)Two trunks rise from a single set of roots. The base of the trunks generally touch and may be joined to each other up to a short distance above the soil. One trunk is taller and thicker than the other, and both are clearly visible from the bonsai's front. Branches from the two trunks extend left, right, and backwards, but not directly toward each other.
Three-trunk(Sankan)Three trunks rise from separate sets of roots. Trunk sizes are varied, with one dominant trunk being the thickest and generally the tallest. The three trunks are placed so that a straight line cannot intersect all three, to minimize symmetry and make the design look as natural as possible.
Five-trunk(Gokan)Modifying the stylistic constraints of the "three-trunk" style, the five-trunk style allows a second dominant tree to be placed in the design. This tree is subordinate to the largest in size. Larger-numbered group styles (seven-trunk, nine-trunk, forest, etc.) also allow a second or third tree to dominate additional groups of trees in the larger design.
Seven-trunk(Nanakan)(See "five-trunk".)
Nine-trunk(Kyukan)(See "five-trunk".)
Clump(Kabudachi, kabubuki)In the clump style, three or more (should be an odd number) trunks grow from a single point. The natural equivalent might be a group of trees that have sprouted from a single cone, or a collection of mature suckers springing from the base of a single tree.
Turtle, stump(Korabuki)This style is similar to the clump style, but the trunks do not rise from a fairly flat surface root system. Instead, the ground-level roots form a domed or turtle-back shape, and the multiple trunks rise from it.
Raft, straight-line(Ikadabuki)These styles mimic a natural phenomenon that occurs when a tree topples onto its side, for example, from soil eroding beneath the tree. Branches along the top side of the trunk continue to grow as a group of new trunks. Sometimes, roots will develop from buried portions of the trunk. Raft-style bonsai can have sinuous or straight-line trunks, all giving the illusion that they are a group of separate trees, while actually being the branches of a tree planted on its side. The straight-line style has all the trees in a single line.
Raft, sinuous(Netsunagari, netsuranari)This style is like the straight-line raft, but the underlying trunk has several bends in it. The trees growing up from it do not appear in a straight line.
Two-tree(Soju)In all multiple-trunk styles, conventional bonsai specimens use trees of the same species. As with the twin-trunk style, the two-tree style has a dominant, larger tree and a smaller one. The two trees may be set very close to one another, as in the twin-trunk style. They may also be set apart, as they do not share a single root.
Three-tree(Sambon-yose)The three-tree through nine-tree styles are considered "group settings" rather than forests. The smaller number of trees means that some stylistic goals, such as having no more than two trees in line with each other, may be applied to these bonsai. Trees in groups settings vary in trunk width and height, but generally resemble each other in proportions, density of foliage, and other visual characteristics. In the three-tree style, a single tree will be the dominant one. The other two will be smaller and usually differ in size from each other.
Five-tree(Gohon-yose)As for "three-tree", but there may be two dominant trees. One will be larger than the other, and the remaining three will be noticeably smaller.
Seven-tree(Nanahon-yose)(See five-tree.)
Nine-tree(Kyuhon-yose)(See five-tree.)
Forest(Yose-ue)This style describes a planting of many trees, typically an odd number unless too many to count easily, in a bonsai pot. The pot has very low sides, to emphasize the height of the trees, and may be replaced by a flat slab of rock. The trees are usually the same species, with a variety of heights employed to add visual interest and to reflect the age differences encountered in mature forests. (For mixed-species plantings, see the Japanese art of saikei.) The goal is to portray a view into a forest, and perspective effects, such as placing the smallest trees toward the rear, are important in developing a specimen in this style.
Literati(Bunjingi)This style has a generally bare trunk line, with branches reduced to a minimum, and typically placed near the apex of a long, often contorted trunk. This style derives its name from the Chinese literati who created Chinese brush paintings like those found in the ancient text, The Mustard Seed Garden Manual of Painting. Their minimalist landscapes often depicted trees growing in harsh conditions, with contorted trunks and reduced foliage. In Japan, the literati style is known as bunjin-gi. (Bunjin is a translation of the Chinese phrase wenren meaning "scholars practiced in the arts" and gi is a derivative of the Japanese word, ki, for "tree").
Broom(Hokidachi)This style is employed for trees with extensive, fine branching, often with species like elms. The trunk is straight and upright. It branches out in all directions about ⅓ of the way up the entire height of the tree. The branches and leaves form a ball-shaped crown, which can also be very beautiful during the winter months.
Octopus(Takozukuri)An uncommon style, these bonsai have a relatively short, thick trunk topped by several long branches that are contorted into curved shapes, fancifully resembling octopus tentacles.
Wind-swept(Fukinagashi)This style describes a tree that appears to be affected by strong winds blowing continuously from one direction, as might shape a tree atop a mountain ridge or on an exposed shoreline. The windswept characteristic can be applied to a number of the basic styles, including informal upright, slanting, and semi-cascade. Multi-tree bonsai can also be developed with elements of the windswept style.
Raw material

For one thing, I made a rock planting last night where the tree is planted in the bonsai soil but is weaved with a rock. That doesn't really fit with any of the descriptions above.

Are you only considering Japanese styling? Chinese and Japanese windswept vary.

Wouldn't all the varying quantities of trees you listed be subcategories of Forest though?
No.
The three-tree through nine-tree styles are considered "group settings" rather than forests.

Penjing is not a style of bonsai but I might add it anyway.

According to Peter Warren group and forest is the same thing. And I've seen those groups as a single style in other books.

And considering the Japanese didn't invent the art of trees in pots to ignore their founding form as "not bonsai" is somewhat odd. But I guess if you want to mince words that's fine. More power to you. It's the argument of whether meatloaf is meat. meat is 95% of the ingredients but you focus on the other 5% added.

I'm not sure of your purpose with this, but it's a good list. Personally, I'd make it comprehensive and include some of the styles/sub-styles that others have mentioned.

If you hit all the Japanese styles there are very few left. No list would be complete without the African styles.

I have never heard of the "turtle" style before, but I think I have an example in the works?

It makes sense to have just one list for the classic Japanese styles or forms. A bigger and very interesting project would be to compile similar lists for the other potted dwarfed tree/tray landscape traditions: Chinese, Southeast Asian, African?, American and European bonsai nouveau.

IDK man. I thought raft and turtle were the same but apparently not. And I believed wikipedia that group and forest were different but that apparently isn't true either. *shrug*

Making lists, similar to my posting on bonsai forums, is just an activity to distract one from actually working on their trees.

I'm being sarcastic, if it helps you organize your thoughts, lists are good.

Just remember that you are in the USA, few Americans really understand the Japanese aesthetics involved in bonsai.

Turtle is distinctly different from raft. When you have a caudex, that is kept mostly buried, or a lignotuber, or a massive root burl type structure, and the trunks sprout from the surface of the underground structure. In bonsai the woody caudex, or lignotuber or burl is exposed just a small amount, to mimic the hill or mountain, and each trunk mimics a separate tree. It is a look that is unique, probably the coast redwood burl would be the most common version of this in North America.

Sumo - this style was not mentioned on your list. A trunk with very drastic taper, where the trunk is as wide at the soil like as the tree is tall. Usually trident maples are the one species that gets this shape most easily. It is not east to develop.
