垂果山蚂蝗  chui guo shan ma huang

Desmodium pendenticarpum C. Z. Gao & Q. R. Lai, Bull. Bot. Res., Harbin 9(4): 41. 1989.

Subshrubs, prostrate or ascending, to 1 m tall. Young branchlets white adpressed villous. Leaves 3-foliolate; petiole 0.7–1.8 cm, villous; leaflet blade elliptic, narrowly elliptic, or obovate-elliptic, 1.7–4 × 1.1–2 cm, abaxially densely white villous, adaxially glabrous, base broadly cuneate or rounded, apex rounded or obtuse.

Corolla purple, ca. 6 mm; standard broadly ovate-orbicular or orbicular; wings auriculate at base; keel nearly spatulate, curved. Pod pendent, 0.9–2 cm × ca. 2 mm, adpressed gray-white villous, conferted, lower suture undulate, upper suture straight, 3–8-jointed. Fl. Aug, fr. Oct.

* Mountain slopes; ca. 100 m. S Guangxi.

One of us (Huang) treats this taxon here as a variety of D. strigillosum based on the difference in indumentum of the branchlets, the pods, petioles, abaxial surface of the leaflets, as well as the difference in corolla color between both species. However, one of us (Ohashi. J. Jap. Bot. 70(2): 115. 1995) treats Desmodium pendenticarpum as a synonym of D. strigillosum.

The typical variety occurs in Cambodia, Indonesia, Laos, Myanmar, and Vietnam, and is introduced in Australia. It is an erect shrub or subshrub, to 60 cm tall, with branchlets, petioles, and leaflets abaxially densely appressed gray or silver silky-hairy; rachis of the inflorescence with dense appressed white or silver silky hairs, intermixed with hooked hairs; corolla blue; pod densely minutely hooked hairy and long straight white hairy.

18. Desmodium reticulatum Champion ex Bentham, Hooker's J. Bot. Kew Gard. Misc. 4: 46. 1852.

显脉山绿豆  xian mai shan liu dou

Desmodium heterocarpon (Linnaeus) de Candolle subsp. angustifolium H. Ohashi.

Subshrubs, erect, 30–60 cm tall. Leaves 3- or sometimes 1-foliolate near lower stem; petiole 1.5–3 cm, sparsely hairy; terminal leaflet blade narrowly ovate or ovate-elliptic to narrowly elliptic, 3–5 × 1–2 cm, lucid, abaxially adpressed pilose, adaxially glabrous, base slightly cordate, both ends obtuse or apex acute. Racemes terminal, 10–15 cm or longer; rachis densely hooked-hairy, remotely 2-flowered at each node. Pedicel ca. 3 mm, glabrous. Calyx 4-lobed; lobes ca. as long as tube. Corolla pink or blue, ca. 6 mm; standard ovate-orbicular; wings obovate-oblong, wings and keel distinctly curved. Pod oblong, 1–2 cm × ca. 2.5 mm, subglabrous or hooked-pubescent, lower suture undulate, upper suture straight, 3–7-jointed. Fl. Jun–Aug, fr. Sep–Oct.

Thickets, grassy slopes; 200–1300 m. Guangdong, Guangxi, Hainan, S Yunnan [Myanmar, Thailand, Vietnam].

This is a species similar to Desmodium heterocarpon, but it differs from the latter by the terminal leaflets usually narrowly elliptic, narrower, thicker, lucid adaxially; inflorescences longer and laxly flowered. Ohashi considers it as a subspecies of D. heterocarpon due to fundamental similarity in having erect or ascending loments comprising quadrate articles of 2.5–3 mm long.

The Hylodesmum podocarpum complex is extremely variable in shape of the terminal leaflets, although they resemble each other in having lax-flowered inflorescences, small flowers, non-clawed wings and keel petals, broadly subobovate small articles and areas of distribution. The taxonomic ranks for these infraspecific taxa are somewhat confusing. Huang considers the complex to consist of one species Podocarpium podocarpum including four varieties, while Ohashi and Mill (2000) consider one species Hylodesmum podocarpum including three subspecies of which one contains a variety.

1a.     Terminal leaflet broadly obovate, broadest above middle, apex abruptly acute  7a. subsp. podocarpum

1b.     Terminal leaflet not as above, broadest below middle.

2a.    Terminal leaflet broadly ovate or ovate, apex acuminate; leaves approximate below middle  7b. subsp. fallax

2b.    Terminal leaflet ovate, rhombic-ovate, elliptic-rhombic, lanceolate-rhombic, or lanceolate, apex acute; leaves scattered or partly approximate at middle.

3a.     Terminal leaflet lanceolate or narrowly lanceolate, 4–6 × as long as wide   7d. subsp. szechuenense

Shrubs or shrublets. Leaves pinnately 3-foliolate; stipules narrowly triangular or rarely triangular to deltoid-ovate, persistent; stipels nearly always absent, or rarely always present, linear; leaflets entire. Inflorescences axillary, racemose, rarely umbellate or spicate, sometimes terminal panicle composed of several upper racemes with reduced subtending leaves; bracts persistent or caducous, 1-flowered per bract; pedicels articulate; bracteoles 2, usually caducous before anthesis. Calyx campanulate, 4-lobed; lower lobe narrower and longer than upper and lateral ones, upper lobe minutely 2-toothed at apex. Corolla violet to pinkish white or rarely yellow; standard shortly clawed at base; wings auriculate and clawed at base; keel incurved at ca. a right angle, acute at apex, auriculate, clawed at base. Stamens monadelphous, vexillary stamen connate to staminal tube ca. 2/3–4/5 of their length, rarely almost diadelphous. Pistil minutely stipitate; ovary 1-ovuled, superior; style filiform, incurved; stigma terminal, small, ciliate with minute hairs. Pods compressed, lenticular, indehiscent, 1-seeded.

Corolla purple; standard elliptic, 10–13 mm, apex obtuse; wings 10–12.5 mm, clawed at base; keel incurved, 12.5–15 mm, clawed at base. Ovary 2.5–3 mm, shortly appressed hairy; style incurved, ca. 10 mm. Pod ovoid, 6–9 × 4–5.5 mm, shortly ascending hairy, apex obtuse. Seeds purplish black, reniform, ca. 2 × 4 mm. Fl. and fr.

* Mountain slopes, thickets, forests; 600–1600 m. Guizhou, Yunnan.

The wings of this species are sometimes not so prominent, especially on the petioles of upper small leaves. In such a form, this species somewhat resembles Campylotropis polyantha, but it is easily distinguished from the latter by the lack of stipels and longer calyx lobes (3–4.5 mm in C. henryi vs. 1.3–2.5 mm in C. polyantha). Campylotropis henryi had been recorded from Thailand (Gagnepain (1920), as L. henryi (Schindler) Gagnepain) and Laos (Thuân 1987), but these are C. decora.

Corolla reddish purple; standard obovate-oblong, 1–1.1 cm × ca. 5 mm, auriculate, shortly clawed; wings narrowly oblong, shorter than standard and keel, auriculate, slender clawed; keel petals slightly falcate, subequal to standard, distinctly auriculate and clawed. Ovary densely hairy. Pod ovoid, 8–10 mm, somewhat densely sericeous, reticulate veined. Fl. Jul–Sep, fr. Sep–Oct. 2n = 22@.

Arid mountain slopes, roadsides, thickets; ca. 800 m. Anhui, Fujian, Guangdong, Guangxi, Guizhou, Henan, ?Hubei, Hunan, Jiangsu, Jiangxi, Sichuan, Zhejiang [Japan, naturalized].

Because this species tolerates arid soils, it is used for soil conservation.

Lespedeza merrillii Ricker was described from Zhejiang (Lingnan Sci. J. 20: 202. 1942). Its description is based on a single specimen (C. Y. Chiao 14377). Ricker said that this species is nearest to Lespedeza davidii Franchet, but at once distinguished from it by the sparsely appressed, instead of velvety, pubescence of the stems and longer calyx teeth. One of us (Huang) follows Li and Chen (1995) retaining L. merrillii here due to the lack of specimens. Two of us (Ohashi and Nemoto) regard this species as merely a glabrous form of L. davidii.
