 common, especially southward. Aug. 



17. D. MarildlKliciim, Boott. Nearly smooth throughout, slender;

-- - *- Stems reclining or prostrate : racemes loosely flowered. 



18. D. lilicatuili, DC. Stem minutely pubescent, striate-angied ; leaflets

 stalked. Virginia and southward. 



18. L.ESPEDEZA, Michx. BUSH-CLOVER. 



Calyx 5-clcft, the lobes nearly equal, slender. Stamens diadelphous (9 & 1) : 

 anthers all alike. Pods of a single 1-seeded joint (sometimes 2-jointed, with 

 the lower joint empty and stalk-like), oval or roundish, flat, reticulated. 

 Perennials with pinnately 3-foliolate leaves, not stipellate. Stipules and bracts 

 minute. Flowers often polygamous. (Dedicated to Lespedez, the Spanish 

 governor of Florida when Michaux visited it.) 

 * Flowers of two sorts, the larger (violet-purple) perfect, but seldom fruitful, panicka 



or clustered; with smaller pistillate and fertile but mostly apetalous ones intermixed, 



or in subsessile little clusters. 



1. Ju. procumfbeilS, Michx. Soft-doivny, except the upper surface of 

 the leaves, trailing, slender ; leaflets oval or elliptical ; peduncles slender, mostly 

 simple, few-flowered. Sandy soil, commonest southward. Aug. The apet- 

 alous fertile flowers, as in the rest, have short hooked styles. 



2. It. rcpciis, Torr. & Gray. Smooth, except minute close-pressed scattered 

 hairs, prostrate, spreading, veiy slender; leaflets oval or obovate-elliptical (' 

 long); peduncles slender and few-flowered ; pods roundish. Dry sandy soil, 

 S. New York to Kentucky and southward. Much like the last. 



3. L*. violacea, Pers. Stems upright or spreading, branched ; leaflets 

 varying from oval-oblong to linear, whitish-downy beneath with close-pressed 

 pubescence; peduncles or clusters few-flowered ; pods ovate. The principal vari- 

 eties are, 1. DIVERGENS, with oval or oblong leaflets and loosely panicled 

 flowers; this runs into, 2. SESSILIFL6RA, with the flowers principally on pe- 

 duncles much shorter than the leaves, and clustered ; and a more distinct form 

 is, 3. ANGUSTIF6LIA, with closely clustered flowers on straight branches,
