华腺萼木 hua xian e mu

Adenosacme longifolia (Wallich) J. D. Hooker var. sinensis Hemsley, J. Linn. Soc., Bot. 23: 379. 1888; Mycetia oligodonta Merrill; M. sinensis f. angustisepala H. S. Lo.

Shrubs or subshrubs, 0.2-0.5(-1) m tall; branches densely hirtellous or strigillose to glabrous. Leaves isophyllous or slightly anisophyllous; petiole 0.2-2 cm, hirtellous or strigillose to glabrous; blade drying submembranous, usually pale, and slightly grayish green, oblong-lanceolate to elliptic-oblong, ovate, or elliptic, 8-20 × 3-5 cm, adaxially sparsely hispid to glabrous, abaxially glabrous or puberulent, hirtellous, or hispidulous at least on veins, base obtuse to cuneate then usually long decurrent, apex acute to acuminate; secondary veins 5-20 pairs; stipules usually persistent, elliptic-oblong, obovate, or suborbicular, markedly contracted to stipitate at base, 3-18 mm, sometimes veined, hispidulous, hirtellous, or glabrous, obtuse or rounded. Inflorescences terminal, laxly cymose, many flowered, glabrous, deflexed to pendulous; peduncles 3.5-7 cm; branched portion 2-7 × 2-16 cm; bracts elliptic, obovate, reniform, or stipuliform, sometimes fused in pairs, 1-3 mm, marginally entire or with stipitate glands, these 0.2-0.5 mm; pedicels 1-2.5 mm. Flowers pedicellate. Calyx glabrous; hypanthium portion subglobose to obconic, 1-2 mm; limb deeply lobed; lobes lanceolate, spatulate, or triangular, 1-2 mm, entire or with 1-3 pairs of stipitate glands. Corolla white, tubular, outside glabrous; tube 5-7 mm, inside apparently glabrous; lobes ovate, 1.5-2 mm. Berries subglobose, 4-4.5 mm in diam., glabrous. Fl. Jul-Aug, fr. Sep-Nov.

● Streamsides or roadsides in dense forests; 200-1000 m. S Fujian, Guangdong, Guangxi, Hainan, Hunan, Jiangxi, Yunnan.

This species is said to be locally common in the notes on several specimens.

H. S. Lo (Guihaia 11: 115-116. 1991) described three forms of this species, which were recognized in FRPS (71(1): 322-323. 1999). Mycetia sinensis f. angustisepala was described from Guangxi and distinguished by its narrowly lanceolate calyx lobes that are ± as long as the "calyx tube" (i.e., the hypanthium portion together with the unlobed portion of the calyx limb); f. "trichophylla" (not a validly published name: Vienna Code, Art. 37.6) was described from Guangdong and distinguished by its leaf blades that are sparsely villous throughout; and f. sinensis presumably has broader and/or differently shaped calyx lobes that are longer than or shorter than the "calyx tube" and glabrous or appressed pubescent leaves. The distinctions used to separate these forms do not seem taxonomically meaningful; accordingly, these forms are not recognized here.
