232 LEGUMINOS& (Harv.) [Hallia. 
2. H. filiformis (Harv.) ; stem jiliform, striate ; stipules adnate with 
. the longish petiole throughout and much lon ger than ut, their points subu- 
late ; leaves very narrow-linear, acute, folded, tapering at base, the 
younger silky-ciliate, the older glabrous ; peduncles setaceous, flecuous, 
much longer than the leaves ; calyx-lobes silky-ciliate.

This singular plant looks like a “ sport ” or monstrosity, and if so, it must have 
sprung from H. alata, judging by the completely adnate stipules, the folded leaflets 
and the tendency to silky pubescence ; but in characters of stem, and in the very 
long stipules and peduncles, it is quite unlike that species. Free portion of the sti- 
pules 5-6 lines long. Peduncles 14~2 inches long. 
3. H. virgata (Thunb. ! Cap. 593); glabrous ; stem angular, flaccid; 
stipules adnate at base to the very short petiole, and longer than it, 
rigid, toothlike, erect ; leaves lanceolate or linear (rarely obovato-lanceo- 
late), acute at each end, flat, rigid; peduncles filiform, shorter than the 
leaf or equalling it; calyx but slightly enlarged in fruit. DO. 7. ¢ ; also

4, H. cordata (Thunb. ! Cap. 593); stem triangular, villous or gla- 
brate ; stipules free, Janceolate or ovato-lanceolate, reflexed, mostly longer 
than the short petiole; leaves cordate at base, ovate-oblong or ovato-lanceo- 
late, acuminate, pilose or glabrate ; peduncles setaceous, nearly equal- 
ling the leaf; calyx villous or glabrate. DC.l.c. BE. § Zt 12 50. H, flac-

Has. Moist places and among grasses, common. (Herb. Th., Hk., Sd., D.) 
Stem sharply 3-angled, trailing, 1-2 feet long, branched near the base ; branches 
simple. Leaves 1-14 inch long, 2-6 lines wide, most commonly oblongo-lanceolate, 
obtusely cordate at base. Pubescence variable, sometimes nearly absent. Leaves 
much narrower and less cordate than in the next,
