LONCHOCARPI. 26. 
This group is nearest related to the Bisulcati be- 
cause of the obcompressed pod inclined to be bisulcate, 
1-celled, stipitate, and opening only along the ventral su- 
ture, but in other features it approaches the Homalobi. 
Stems flexuous, 1-2 ft. high, rather rush-like and, like 
the leaves and peduncles, round, striate, green and rather 
fleshy and drying very slowly, slender. Stipules small, 
rigid, deltoid. Leaves short-petioled, of few distant leaf- 
lets or none. Leaflets nearly filiform, round in cross sec- 
tion or channeled, 1-3 cm. long, blunt, terminal leaflet a 
mere prolongation of rachis and not jointed to it. Pe- 
duncles stout, erect, with the rachis 1-2 dm. long, race- 
mosely few-flowered above the middle. Bracts minute, 
rather broad, shorter than the rather stout pedicels. 
Calyx cylindrical, truncate at both ends (triangular at 
base in lonchocarpus), attached near the middle, the 
teeth shorter than tube which is 3-6 mm. long and 2 mm. 
wide. Flowers about 1-1.5 cm. long, the blades half as long 
and sharply arched and rather wide, pearl-white to 
light-purple. Pods pendent on recurved pedicels which 
are not t.visted, slightly sulcate to much obcompressed 
ventrally, with thick and conspicuous ventral suture 
somewhat raised, acute at both ‚ends and stipitate or con- 
tracted at base and seemingly stipitate, opening along the 
ventral suture and inclined to be explanate, the cavity 
inflated somewhat, smooth to ashy, 2-6 cm. long, nar- 
rowly oblong to linear-oblanceolate, nearly straight, 
ventral suture mostly the more arched, about 5 mm. wide.

2A. Pods long-stipitate, greatly obcompressed so that the cross 
section is nearly linear to oblately deltoid or quadrate, mostly 
very broadly and shallow-sulcate on each side of the thick ven- 
tral suture, pendulous, opening only along the ventral suture 
and explanate with age, coriaceous, often a trifle wider above, 
about 5 cm. long. i
