gume obovate or roundisFi, the lower joint abortive. Sterile flowers furnish- 

 ed (as well as the lertile ones) with 2 lanceolate plumose bracteoles. Calyx 

 ciliate, much shorter than the corolla ; the tube glabrous. Corolla orange- 

 yellow : vexilhun twice as long as the other petals, retuse; wings obovale, 

 with a small tooth at the base of the limb : keel somewhat falcate, truncate 

 at the apex. Ovary at the bottom of the slender calyx-tube and falling off 

 with it. 



40. CHAPMANNIA. 



Flowers of two kinds? Sterile fl. Calyx with 2 bracteoles at the base ; 

 the tube very long and slender, the corolla inserted on its throat; limb5-tooth- 

 ed, the lowest tooth longest and remote from the others. Vexillum round- 

 ish: keel cymbiforin, nearly as long as the vexillum, bifid at the summit. 

 Stamens monadelphous, alternately longer ; anthers all oblong and similar. 

 Ovary sessile, with 2-3 ovules, always sterile : style filiform, very^ long : stig- 

 ma capitate, minute, glabrous. Fertile fl. not seen. — Herbaceous. Stems 

 branched. Leaves unequally pinnate. Stipules small, free. Racemes ter- 

 minal, nearly naked. Flowers small, yellow. 



We dedicate this interesting genus to our friend Dr. A. W. Chapman, an accurate 

 and indefatigable botanist, wlio has largely contributed to our knowledge of the 

 plants of Middle Florida. Although we have not seen the fertile flowers or truit, 

 there can be little doubt of its near affinity to Stylosanthes on the one hand and to 

 Arachis on the other. 



C. Floridana. 



Tampa Bay, East ¥\onAa, Dr. Burrows ! Dr. Leavenworth! May.— 

 Stem 2-3 feet long, erect or somewhat assur^ent, sulcate, hirsute and viscid, 

 particularly above. Leaflets 2-3 pairs, elliptical, oblong, mostly retuse, 8-14 

 lines long, nearly glabrous above, hairy, minutely scaly and of a light purplish 

 color beneath. Stipules very small, subulate, membranaceous. Racemes 

 few-flowered, somewhat paniculate. Flowers rather larger than in Stylo- 

 santhes elatior, each with a small broadly ovate bract and 2 minute lanceo- 

 late bracteoles at the base. Calyx hispid; the tubular base resembling a 

 slender pedicel. Petals nearly equal in length, the claws short : wings ob- 

 long, scarcely toothed at the base: keel-petals cohering at the back except 

 near the summit. Filaments monadelphous below, distinct above: anthers 

 large. Ovary oblong: style nearly straight, cxserted.

Calyx with 2 ovate deciduous bracteoles at the base, bilabiate ; the upper 

 lip bifid or 2-toothed ; the lower trifid or 3-toothed. Corolla inserted into the 

 bottom of the calyx: vexillum roundish: wings oblong: keel cymbiform, 2- 

 parted at the base. Stamens equally diadelphous (5 & 5). Legume com- 

 pressed, straight, exserted, composed of many (rarely few) 1-seeded joints 

 which are usually square at both ends and easily separated from each other. 

 Seeds compressed. — Herbaceous or shrubby plants. Leaves unequally pin- 

 nate, usually with numerous leaflets. Stipules semisagittate. Racemes ax- 

 illary. Flowers often yellow.
