 in allusion to the two kinds of pods.) 



1. A. monbica, Nutt. Racemes nodding; bracts each supporting 2 or 

 more flowers, shorter than the pedicels ; subterranean pods hairy. — Rich wood- 

 lands. Aug., Sept. 



2 9. GALACTIA, P.Browne. Milk-Pea. 



Calyx 4-cleft ; the lobes acute, the upper one broadest, entire. Keel scarcely 

 incurved. Stamens diadelphous or nearly so. Style beardless. Pod linear, flat, 

 several-seeded (some few of them rarely partly subterranean and fleshy or de- 

 formed). — Low, mostly prostrate or twining perennial herbs. Leaflets usually 

 3, stipellate. Flowers in somewhat interrupted or knotty racemes, purplish ; in 

 summer. (Name fro*m yd\a, -ciktos, milk; some species being said to yield a 

 milky juice, which is unlikely.) 



1 . G. glabella, Michx. Stems nearly smooth, prostrate ; leaflets elliptical 

 or ovate-oblong, sometimes slightly hairy beneath ; racemes short, 4 - 8-flowered ; 

 pods somewhat hairy. — Sandy woods, S. New York, New Jersey and Penn. to

30. EHYNCHOSIA, Lour., DC. Rhynchosia. 



Calyx somewhat 2-lipped, or deeply 4 - 5-parted. Keel scythe-shaped, or in- 

 curved at the apex. Stamens diadelphous. Ovules only 2. Pod 1 -2-seeded, 

 short and flat, 2-valved. — Usually twining or trailing perennial herbs, pinnatelv 

 3-foliolate, or with a single leaflet, not stipellate. Flowers yellow, racemose or 

 clustered. (Name from pvvxos, a beak, from the shape of the keel.) 



1 . R. tomentdsa, Torr. & Gray. More or less downy ; leaflets roundish ; 

 racemes short or capitate ; calyx about as long as the corolla, 4-parted, the 

 upper lobe 2-cleft ; pod oblong. — Very variable : or perhaps the following are 

 distinct species. 



Var. monophylla, Torr. & Gray. Dwarf and upright (3' -6' high) ; 

 leaves mostly of one round leaflet 1 ' - 2' wide. ( R. reniformis, DC ) — Virginia 

 and southward, in dry sandy soil. — Flowers earlier than the following. 



Var. volubilis, Torr. & Gray. Trailing and twining, less downy ; leaflets 

 3, roundish ; racemes few-flowered, almost sessile in the axils. (R. diffonnis,

Var. er6cta, Torr. & Gray. Upright (l°-2° high), soft-downy; leaflets 

 3, oval or oblong. (R. erecta, DC.) — Maryland and southward. 



31. BAPTiSIA, Vent. False Indigo.
