棕榈，也称为榈。产于岭南和西川地区，江南地区也有生长。树干高约一、二丈，旁边没有分枝；叶子大而圆，从枝端分歧生长，外皮层层重叠，覆盖在四周，每一层皮环绕一圈算作一节，每二十天重新在上面长出新的。六、七月间开出黄白色的花；八、九月结出果实，形状像鱼子一样成房状，颜色为黑色。九月、十月采集其树皮和木质部分使用。《山海经》记载：石脆（一作翠）之山，那里的树木多是棕树，说的就是这种植物。
椿木、樗木，旧有的本草书籍都没有记载它们出产的州县土地，如今南北各地都有生长。这两种树的形态主干大致相似，但椿木质地坚实且叶子有香味可以食用，樗木质地疏松且有臭味，厨师也能通过熬煮去除其气味。北方人称呼樗木为“山椿”，江东人称呼它为“鬼目”，叶子脱落的地方留下的痕迹像樗蒲子（古代一种游戏用具），又像眼睛，因此得名此名。它的木材最为无用。《庄子》中所说的“我有一棵大树，人们叫它樗，它的树根盘节隆起不符合墨线标准，小树枝弯曲拳曲不符合圆规矩尺的标准，立在路边，工匠们看都不看一眼”指的就是这种树。采摘没有时间限制。《尔雅》说：栲，就是山樗。郭璞注释说：栲树类似樗树，颜色较白，生长在山中，因此得名。它也类似于漆树。俗语说：榖、樗、栲、漆，长得非常相似像是一个样子。《诗经·唐风》中说：山上长着栲树。陆机疏解说：山樗与田樗没有区别，只是叶子稍微窄一些罢了。吴地人用它的叶子制作茶茗。许慎将“栲”读作“糗”，现在的人说“栲”字失去了原本的读音罢了，然而这确实是樗树的别种。樗根煮成的汁液，主治便血以及小儿疳积痢疾。也可以取白色树皮与仓米、葱白、甘草、豆豉一同煎煮，服用后，血痢就会停止。唐代刘禹锡撰写的樗根馄饨法记载：每到立秋前后，就患有痢疾，或者是水谷痢兼带腰痛等症状，取一大两樗根，捣碎筛粉，用好面粉捏制成馄饨子，大小如皂荚子，用清水煮熟，每天空腹服用十枚，没有任何禁忌，效果神奇良效。
Zonglv (Palmae Fructus et Cortex), also known as Lv. It is produced in Lingnan and Xichuan, and is also found in the Jiangnan region. The tree trunk is one or two zhang high, with no branches on the sides; the leaves are large and round, growing dichotomously at the branch tips, covered by overlapping bark layers on all four sides, where each complete circle of bark constitutes a node, regenerating upwards every twenty days. Yellowish-white flowers appear in June and July; fruits develop in August and September, forming clusters resembling fish roe, black in color. Its bark and wood are harvested for medicinal use in September and October. The *Classic of Mountains and Seas* states: "On the Mountain of Cuicui (or Cuicui), the trees are mostly Zong," referring to this plant.
Chunmu (Toona Sinensis Wood) and Chumu (Ailanthus Altissima Wood) were not previously recorded regarding their specific origins. Now they are found throughout the north and south. The trunks of these two trees are generally similar in shape, but Chunmu is solid in texture and its leaves are fragrant and edible, whereas Chumu is spongy and has an offensive odor, which cooks can remove through boiling. People in the north call Chumu "Shanchun" (Mountain Toona), while people in Jiangdong call it "Guimu" (Ghost Eye). The marks left where leaves fall resemble seeds of Chuipu (a board game piece) or eyes, hence the name. Its wood is considered useless. This refers to what is mentioned in the *Zhuangzi*: "I have a great tree, called Chum. Its roots are gnarled and do not fit the carpenter's line; its small branches are twisted and do not fit the compass and square. Standing by the road, craftsmen do not even glance at it." There is no fixed time for harvesting. The *Erya* states: "Kao is Shanchu." Guo Pu's commentary notes: "Kao resembles Chum, is lighter in color, grows in mountains, and thus gets its name." It is also similar to Lacquer trees. Folk sayings state: "Gu, Chum, Kao, and Qi (Lacquer) look so similar as if they were one." The *Book of Songs · Tang Feng* says: "The mountain has Kao trees." Lu Ji's annotation explains: "Mountain Chum is no different from Field Chum, except the leaves are slightly narrower." People in Wu use its leaves to make tea. Xu Shen read "Kao" as "Qiu"; nowadays people pronounce "Kao" losing its original sound, yet it is indeed a variant species of Chum. Decoction of Chum root treats lower bleeding and pediatric ganji dysentery (malnutrition with dysentery). One may also take the white bark and decoct it together with Cangmi (stored rice), scallion whites, Gancao (Licorice Root), and Chi (fermented soybeans); drinking this will stop bloody dysentery. Liu Yuxi of the Tang Dynasty wrote a recipe for Chum Root Wonton: Around the beginning and end of Liqiu (Start of Autumn), when suffering from dysentery, or water-and-grain dysentery accompanied by lower back pain, take one da liang of Chum root, crush and sieve it, mix with fine flour to form wonton shapes the size of Gengwanzi (Seabuckthorn seed), boil in clear water, and take ten pieces on an empty stomach daily without any dietary restrictions; the effect is miraculous and excellent.
