Premna microphylla is a tree[4] in the mint family (Lamiaceae).[3]
Names
editP. microphylla has the English common names Japanese premna,[5] (Japanese) musk maple,[6] and Japanese neem tree.[6]
The specific epithet microphylla derives from Greek μικροϛ (micros) and φυλλον (phyllon) and means 'small leaves'.[6][7] The name for the genus Premna derives from the Greek πρέμνον (premnon, tree stump) refers to the short trunks that some species have.[6]
In Japanese it is called ハマクサギ (hamakusagi).[4]
In China, it is known as 豆腐柴 (dòufu chái 'tofu wood'), 斑鸠树 (bānjiū shù 'turtledove tree'),[8] 臭黄荆 (chòu huáng jīng 'stinky yellow thorn'), 腐蜱 (fǔ pí 'rotten tick'), and 观音草 (guānyīn cǎo 'Guanyin grass').[9]
In Taiwan it is called 臭黃荊 (chòu huáng jīng)[10]
The plant is called cách lá nhỏ in Vietnamese.[11]

Uses
editP. microphylla is used for food. The leaves can be used to make a pectin-rich gel that is something like tofu.[9][8] This green gel is called 神仙豆腐 (shénxiān dòufu, immortal/divine tofu)[8] or 观音豆腐 (Guānyīn dòufu, Guanyin tofu).[9]
The plant is also used for bonsai because of its small, strong-smelling leaves.[12] The bonsai trunks are evocative of driftwood, similar to shimpaku juniper.[12] A specimen of P. microphylla was used as an autonomous bonsai in the art installation titled Premna Daemon.[13][14][15][16]
Description
editP. microphylla is a tree[4] and has square, woody, mostly smooth stems and branches.[2] The plant reaches 2–6 m in height.[9] It grows and a nanophanerophyte or phanerophyte.[3]
The leaves are sessile, ovate-lanceolate in shape and tapered near the tip.[2] The leaf margins are serrate from the middle to the apex.[2] Both sides of the leaves are scabrous and covered with very short 'hairs'.[2] The leaves have a strong odor[9] that has been compared to those Serissa.[12]
The flowers are hermaphroditic. The 5-part calyx is short and surrounds a funnel-shaped corolla[2] that is pale yellow.[9] The petals are 0.3–0.4 inches (7.6–10.2 mm) long.[2] The cream-colored and zygomorphic flowers bloom in May and August[4]
The drupe is obovate to nearly spherical and purple-black when ripe.[9]
Major compounds found the the essential oil include blumenol C, β-cedrene, limonene, α-guaiene, cryptone, and α-cyperone.[17]
Distribution
editThe plant is found in southern China,[2][3], central and southern Japan,[3][4] and Taiwan.[3][10] It prefers growing in slightly acidic to acidic soil mainly on woodland edges or understory at an altitude of 500–1000 m in elevation.[9]
Ecology
editThe growing season is yearly from March to November.[9] The pollination syndrome for P. microphylla is melittophily, with bee and wasp pollinators including Xylocopa amamensis, Cerceris yuwanensis, and Hylaeus insularum.[4]
