Lespedeza 



Desmodium oxyphyllum DC. (D. racemosum (Thunb.) DC.) (Brit. 7:214). Shrub, 

 to lm.; fls. pink or purple, small, less than 5mm. long, VIII-IX; fr. IX-X. 

 Eastern Asia; locally in An., Che., Ki., Ku. Brushland. Fig. 175. 

 Desmodium podocarpum DC. [llS^f (Shan Tou Tzu; Mountain Bean) (Brit. 7:208). 

 Suffrutescent, to lm.; fls. pink, VII-VIII; fr. IX. Eastern Asia; locally in An., 

 Che., Ku. Brushland and forest. 



15. Campylotropis Bunge ^It#M (Wan Lung Ku Shu) 

 Deciduous shrubs with 3-foliolate lvs.: fls. usually purple, solitary in the axils of 

 deciduous (ours) or persistent bracts: otherwise like Lespedeza. About 40 species, in 

 Asia; 20 in China. (Greek: kampylos, curved, and tropis, keel; referring to the 

 curved keel of the flower.) 



1. Campylotropis macrocarpa (Bunge) Rehd. (R.M. 521). Shrub, to lm.; fls. pink, 

 VIII-IX; fr. X. Northern and central China; locally in An., Ku. Brushland. 



16. Lespedeza Michx. Bush Clover tM^M, (Hu Chih Tzu Shu) 

 Deciduous shrubs, or herbaceous annuals, with mostly 3-foliolate lvs.: fls. small, 

 but often of 2 kinds, in conspicuous clusters, the apetalous fertile; bracts of the in- 

 florescence persistent; pedicels often 2-4 together, bearing 1 or 4 persistent bracteoles 

 at the base of the calyx; stamens grouped 9 and 1: pods 1-seeded. About 50 species, 

 in North America, Asia and Australia; about 20 in China. (Name misspelled, for 

 Cespedez, a Spanish governor of Florida, who aided Michaux.) 



Key to the Species 



a. Shrubs, woody at least at the base: pedicels often long and slender, 

 bearing a single bracteole. 

 b. Fls. clustered or scattered, but not on long slender peduncles, 

 c. Pods at maturity longer than the calyx and not in dense 

 fasciculate clusters: not with stems, lvs. and calyces 

 all spreading-pubescent. 

 d. Lfts. cuneate or obovate: plants mostly erect. 



e. Lfts. cuneate: appressed-pubescent or sericeous 

 beneath. 

 Lfts. narrowly cuneate: stems stiffly erect and 

 densely If y. : fls. many, 4-5 mm. long, yellow 

 with purple veins, in small clusters in the 

 axils of many lvs. up and down the stem: 

 pods sometimes not much exceeding the 



calyx, abruptly mucronate 1. 



Lfts. broadly cuneate: stems erect but not 

 densely If y . : fls. many, 7-10 mm. long, 

 purple, clustered near the tips of the brs.: 



pods of perfect fls. 3 x the calyx 2. 



ee. Lfts. obovate to nearly orbicular. 



Stems stout and erect: lfts. oblong-ovate- 



cuneate, rounded or emarginate at the tip: 



fig. racemes on peduncles 1-3 cm. long; fls. 



purple. 



Calyx lobes setaceous: lfts. oblong-cuneate. 



Calyx lobes acuminate but not setaceous: lfts. 



ovate 4

L. floribunda
