PEA FAMILY. 



419 



filiform, not bearded. Pods from the upper flowers linear-oblong, several-seeded, 2-valved, 

 those from the lower obovoid, fleshy, mainly i-seeded. [Latin, referring tn the curved keel 

 of the corolla.] 



About 7 species, natives of North America, eastern Asia and the Himalayas. Only the follow- 

 ing are known in North America. Type species; Falcata caroliniana (Walt.) Gmel. 

 Leaves thin ; bracts small ; plant pubescent or glabrate. i. F. comosa. 



Leaves firm ; bracts large ; plant villous-brown-pubescent. 2. F. Pitcheri.

 Falcata comosa Kuntze, Rev. Gen. PI. 182. 1891. 



Slender, simple or sparingly branched, climbing, 

 pubescent or glabrate, i°-8° long. Stipules oblong 

 or ovate, 2" long, striate ; leaflets broadly ovate 

 or rhombic-ovate, acute at the apex, rounded at 

 the base, the lower inequilateral, i'-3' long; 

 racemes of petaliferous flowers mainly simple; 

 bracts small, ovate, obtuse ; flowers purplish or 

 white, 6"-7" long ; pedicels equalling or exceeding 

 the bracts; pods of the petaliferous flowers about 

 i' long, 3" wide, pubescent. 



Moist thickets. New Brunswick to Florida, west 

 to Manitoba, Nebraska and Louisiana. Aug.-Sept. 

 Pea-vine. American licorice. 



2. Falcata Pitcheri (T. &G.) Kuntze. 

 Pitcher's Hog Pea-nut. Fig. 2639. 



Amphicarpaea Pitcheri T. & G. FI. N. A. i : 



292. 1838. 

 F. Pitcheri Kuntze, Rev. Gen. PI. 182. 1891. 



Similar to the preceding but generally 

 stouter, villous-pubescent throughout with 

 reflexed brown hairs. Leaflets larger and 

 thicker, sometimes 4' long; pedicels mostly 

 shorter than the nearly orbicular canescent 

 bracts ; ovary and pods of the petaliferous 

 flowers pubescent throughout, subterranean 

 fruit less abundantly produced than in F. 

 comosa; calyx larger. 



Moist thickets, Massachtisetts to Virginia, 

 New York, South Dakota, Tennessee and 

 Texas. Perhaps a race of the preceding spe- 

 cies. Aug.-Sept. 



46. GALACTIA P. Br.; Adans. Fam. PI. 2: 322. 1763. 



Prostrate or climbing perennial vines (sometimes erect and shrubby), mainly with pm- 

 nately 3-foliolate leaves, small and deciduous stipules, and purple or violet axillary racemose 

 flowers. Calyx 4-lobed, bracteolate, the lobes acute, often as long as the tube. Standard 

 orbicular or obovate. Wings narrow, obovate, adherent to the narrow, nearly straight keel. 

 Stamens diadelphous or nearly so (9 and l) ; anthers all alike. Ovary nearly sessile ; ovules 00 ; 

 style filiform, not bearded. Pod linear, straight or slightly curved, usually flattened, 2-valved, 

 several-seeded. Fleshy few-seeded pods are sometimes produced from subterranean apetalous 

 flowers. [Greek, milk-yielding, the typical species described as having milky branches.] 



About 70 species natives of warm and temperate regions, most abundant in America. Besides 

 the following, about 25 others occur in the southern and southwestern states. Type species : Glycine 

 Galactia L.
