Synonyms[3]

Premna microphylla is a tree[4] in the mint family (Lamiaceae).[3]

Names

P. microphylla has the English common names Japanese premna,[5] (Japanese) musk maple,[6] and Japanese neem tree.[6] It is also called tofu tree because of the tofu-like food made from the leaves.[7]

The specific epithet microphylla derives from Greek μικροϛ (micros) and φυλλον (phyllon) and means 'small leaves'.[6][8] 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'),[9] 臭黄荆 (chòu huáng jīng 'stinky yellow thorn'), 腐蜱 (fǔ pí 'rotten tick'), and 观音草 (guānyīn cǎo 'Guanyin grass').[10] In Taiwan it is called 臭黃荊 (chòu huáng jīng)[11] The plant is called cách lá nhỏ in Vietnamese.[12][13]

Uses

P. microphylla is used for food. The leaves can be used to make a pectin-rich gel that is something like tofu.[10][9] The jelly is similar to grass jelly but it not usually called that, unlike other grass jelly plants. This green gel is called 神仙豆腐 (shénxiān dòufu, immortal/divine tofu)[9] or 观音豆腐 (Guānyīn dòufu, Guanyin tofu).[10] In English it is sometimes called green leaf tofu.[7] The leaves are high in protein (13.48%),[10] and while not as much as soybeans, it is high for a leaf vegetable and ranks closer to cereal grains like hard wheat (12.6%) rather than spinach (2.9%).[14][15] To make the 'tofu', the leaves are washed and crushed with some water to facilitate grinding.[10] Culinary ash is added to the strained mixture and it is allowed to set.[10] Some cooks use burn specific wood for the ash, such as Osmanthus.[16] The dish is considered a refreshing summer treat.[10] Production is small and local, and not done on an industrial scale.[10]

Much effort has been made to develop P. microphylla as an industrial source of pectin.[10] The leaves contain 30-40% pectin,[10] much higher than the typical sources, apple pomace (10-15%) and citrus peel (20-30%).[17]

The plant is also used for bonsai[6] because of its small, strong-smelling leaves.[18] The bonsai trunks are evocative of driftwood, similar to shimpaku juniper.[18] A specimen of P. microphylla was used as an autonomous bonsai in the art installation titled Premna Daemon.[19][20][21][22]

Description

P. microphylla is a tree[4] and has square, woody, mostly smooth stems and branches.[2] The plant reaches 2–6 m in height,[10] and ~3 m wide.[6] It grows and a nanophanerophyte or phanerophyte.[3]

The leaves are sessile, ovate-lanceolate in shape and tapered near the tip.[2] The leaves grow in an opposite pattern.[6] 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[10] that has been compared to those Serissa.[18]

The flowers are hermaphroditic[2] and grow in conical panicles.[6] The 5-part calyx is short,[2] cup-shaped, and purplish-green.[6] The calyx surrounds a funnel-shaped corolla[2] that is pale yellow.[10][6] 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.[10][6]

Major compounds found in the essential oil include blumenol c, β-cedrene, limonene, α-guaiene, cryptone, and α-cyperone.[23]

Distribution

The plant is found in southern China,[2][3][6] central and southern Japan,[3][4] and Taiwan.[3][11][6] The type specimen was collected by Scottish botanist and plant hunter Robert Fortune in China.[2] It prefers growing in slightly acidic to acidic soil mainly on woodland edges or understory at an altitude of 500–1,000 metres (1,600–3,300 ft) in elevation.[10]

Ecology

The growing season is yearly from March to November.[10] The pollination syndrome for P. microphylla is melittophily, with bee and wasp pollinators including Xylocopa amamensis, Cerceris yuwanensis, and Hylaeus insularum.[4] There are no major diseases or insect pests known.[6] There is some evidence that sika deer will nibble on the tree occasionally.[24]
