* Leaves punctate with black glands. 
1. H. Jamesii Torr. & Gray. Herbaceous and finely pubescent: pinnae 2 or 3 
pairs and an odd one; the small oblong leaflets 5 to 9 pairs: pods broad, more or Jess 
lunate, 2.5 em, long, 2 or 3-seeded, sprinkled (as well as the leaves, calyx, and petals) 
with sessile black glauds.—Throughout southern and western Texas. 
2. H. melanosticta Gray. Somewhat shrubby at base: branchlets and racemes 
canescent with short villous retrorse hairs: pinniwe 2 pairs and an odd one; leaflets 
8or4 pairs, obliquely elliptical, together with the rhachis loosely villous, black 
glandular beneath (as are the calyx and pod): pod 2 or 3-seeded, muriculate, the short 
muriculations stellate-pilose at apex.—A very rare species, reported from Texas only 
“in the valley of the RioGrande below Donna Ana” (Mex. Bound. Surv.), and in the 
Chisos Mountaius (Nealley). Resembling H. Jamesii, but with fewer, larger, and 
more distant leaflets, the whole plant more villous, the calyx more densely black- 
glandular, and the pods larger and much more muricate and glandular. 
3. H. brachycarpa Gray. Stems ascending from a lignescent root, slender, leafy 
to the top, minutely pubescent or nearly glabrous: pinne 2 pairs and an odd one; 
leaflets 4 or 5 pairs, elliptical, minutely pubescent or glabrate, lower surface sprinkled 
with large flat black glands: pod oval, nearly equilateral, 2-seeded, 16 to 18 mm, 
long, 8 to 10 mm. broad, the sides puberulent or glabrate, the sutures beset with 
scattered stipitate black glands and with rigid setose-muricate projections.—High 
prairies between the upper Nueces and the Pecos. 
** Leaves destitute of black glands. 
4. H. stricta Benth. Branches sparsely glandular and foliage puberulent or gla- 
brate: pinne 4 to 6 pairs and an odd one; leaflets 6 to 10 pairs, crowded, obliquely 
oval-oblong, blunt and nerveless : raceme strict : claws of the petals long and with copi- 
ous stipitate glands: pod falcate, blunt, glandular, many-seeded.—Common in the 
valleys throughout southern and western Texas. Probably the most common Texan 
Hoffmanseggia, with an esculent tuberous rootstock, and known as ‘‘camote del 
raton.” Var. DEMISSA Gray is low, with lax short-peduncled racemes, pedicels spread- 
ing in flower and recurved in fruit, and pod little if at all faleate.—In the mountains 
west of the Pecos. 
5. H. oxycarpa Benth. Low and slender, from a suffrutescent base: stems and 
petioles villous-pubescent, often with stipitate glands intermixed : pinne 3 tod pairs 
and an odd one; leaflets oblong, nerveless: petals very short-stipitate and hearly 
naked: pod broadly falcate, very acute, stipitate-glandular, 4 to 6-seeded, 2.5 em. 
or more long, 6 to 8 mm. wide.—High stony prairies from Eagle Pass to the Pecos 
and beyond. 
6. H. Drummondii Torr. & Gray. Low and much branched, suffrutescent, gla- 
brous and with a few scattered stipitate glands: pinne 1 pair and an odd one; leaflets 
4 to 6 pairs, elliptical, obtuse or retuse: pod ovate-oblong, strongly falcate, acute, 
glabrous, about 2-seeded.—Between the Colorado (near Austin) and the Rio Grande, 
7. H. caudata Gray. Shrubby and very glabrous (petioles, branchlets and calyx 
with a few small stipitate glands): pinnw 2 or 3 pairs, each with 4 to 7 pairs of leaf- 
lets, and an elongated terminal one with 9 to 15 pairs ; leaflets crowded, thickish, 
rounded, oblique, subcordate, veiny : pod reticulated, acute, furfuraceous-glandolar 
and roughened with blackish glands, the upper suture straight except the ineurved 
apex, about 5 cm. long.—-Sandy ground, between the Nueces and the Rio Grande. 
8. H. drepanocarpa Gray. Low, with many short (2.5 to5 cm.) slender stems 
rising from a thick ligneous root and terminating in the slender peduncle of the 
elongated and loosely flowered raceme (with the peduncle 15 cm. long), every where 
entirely destitute of glands, but minutely cinereous-puberulent: pinne 3 to 5 pairs 
and an odd one; leaflets 9 or 10 pairs, oblong, subfalcate, nerveless, crowded, about 
6mm. long: pod broadly linear, rounded at base and apex, strongly falcate, glabrous 
(or minutely puberulent under a lens), reticulated, impressed between the 9 or 10 
seeds, about 3,5 cm, long and 6 mm, wide,—From the Pecos to New Mexico.
