LEGUMINOS^:. (PULSE FAMILY.) 137 



17. D. Ciliare, DC. Stem slender, hairy or rough-pubescent ; leaves crowded, 

 on very short hairy petioles ; leaflets round-ovate or oval, thickish, more or less hairy 

 on the margins and underneath ('-!' long). Dry hills and sandy fields: 

 common, especially southward. 



18. D. Marilandicum, Boott. Nearly smooth throughout, slender; 

 leaflets ovate or roundish, very obtuse, thin, the lateral ones about the length of the 

 slender petiole : otherwise resembling the preceding. (D. obtusum, DC.) 

 Copses : common. 



H---I- Stems reclining or prostrate: racemes loosely flowered. 



19. D. lineatum, DC. Stem minutely pubescent, striate-angled ; leaflets 

 orbicular, smoothish ('-!' long), much longer than the petiole; pod scarcely 

 stalked in the calyx. Dry soil, Maryland ( W. M. Canby), Virginia and 

 southward. 



20. LESPEDEZA, Mich.* BUSH-CLOVER. 



Calyx 5-cleft ; 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, in summer and autumn. (Dedicated to 

 Lespedez, the Spanish governor of Florida in the time of Michaux.) 

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

 or clustered ; with smaller pistillate and fertile but mostly apetalous ones inter- 

 mixed, or in subsessile little clusters. 



1. L. procumbens, Michx. Soft-downy, except the upper surface of 

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

 simple, few-flowered. Sandy soil : commonest southward. The apetalous 

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



2. L. repens, Torr. & Gray. Smooth, except minute close-pressed scattered 

 hairs, prostrate, spreading, very 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 vary- 

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

 cence; peduncles or dusters few-flowered ; pods ovate. The principal varieties 

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

 this runs into, 2. SESSILIFI^RA, with the flowers principally on peduncles much 

 shorter than the leaves, and clustered; and a more distinct form is 3. ANGUSTI- 

 F6LIA, with closely clustered flowers on straight branches, crowded leaves, and 

 narrowly oblong or linear leaflets, which are often silky. Dry copses : com- 

 mon. Pods ripening from bcth sorts of flowers. 



4. L. Sttivei, Nutt. Stems upright-spreading, bushy, downy; leaflets oval 

 or roundish, longer than the petiole, silky or white- woolly beneath (and some- 

 times above) ; clusters many-flowered, crowded; pods ovate, downy. Dry hills, 

 and sand, Plymouth, Mass, to Virginia, Michigan, and southward. Appear- 

 ing intermediate between No. 3 and No. 5.
