ROBINSON, — SPECIES OF NEPTUNIA. 833 
** Heads considerably smaller, ovoid, about 20-flowered; the lowest flowers often 
with yellow petaloid filaments: bracts ovate, acuminate. 
+ Bracts and calyx-lobes ciliolate. 
N. pubescens, Bentu. Habitally similar to the preceding, finely 
pubescent or at length only glandular-roughened: pinne only 2 or 3 
pairs but leaflets more numerous (15 to 35 pairs), ciliolate upon the 
margin but not otherwise pubescent; stipules larger than in the preced- 
ing species, ovate, acuminate, yellowish-brown or greenish: legumes 
rather short and broad (about 10 mm. in breadth), 3-8-seeded, more 
or less pubescent; the stipe only a line or two in length. — Benth. in 
Hook. Jour. Bot. iv. 356, & Trans. Linn. Soc. xxx. 384 (excl. pl. of 
Florida and perhaps of W. Ind.); Coult. 1. c. WV. lutea, Torr. Bot. Mex. 
Bound. 60, in part, acc. to Wats. Bibl. Index, 244. —S. and W. Texas, 
from Corpus Christi Bay, Palmer, to Eagle Pass, Havard, and perhaps 
farther westward, Wright, (Mex., W. Ind.). This of all our plants 
appears to correspond most closely to specimens from Peru whence the 
Species was originally described. 
indheimeri. Diffusely branched from a lignescent base, con- 
spicuously and persistently pubescent: pinne 3 to 5 pairs; leaflets 15 
to 30 pairs, strongly ciliated on the margin and also pubescent upon the 
lower surface, especially near the apex; stipules, bracts, and even the 
calyx-lobes conspicuously ciliated: fruiting peduncles 2.5 to 6.5 cm, 
long: pods regularly oblong, cuneate at the base, 2.5 to 3.8 cm. long, 
8 mm. broad, more or less pubescent even in age, 3—10-seeded ; stipe 
about 4 mm. long. — WV. lutea, Heller, Contrib. Herb. Frankl. & Marsh. 
Coll. i, 45, not Benth. — Prairies of Texas, about Houston, Lindheimer, 
June, 1843, Texas without locality, Wright, and near Corpus Christi, 
Heller, no. 1822. 
+ + Bracts and calyx-lobes not ciliolate. 
‘ N. floridana, Smatu. Very slender and apparently very sensi- 
tive: stems branched, 6 dm. or more long, prostrate, glabrous: pinne 
3 to 4 pairs; leaflets numerous (15 to more often) 20 to 40 pairs, cilio- 
late but not otherwise pubescent: peduncles long, at anthesis often 
hooked at the apex, in fruit 7.5 to 10 em. in length: bracts and calyx- 
teeth quite devoid of ciliation: pods about 3.2 em. long, 6 mm. broad, 
sparingly pubescent when young, soon glabrate, 7-9 seeded; stipe 2 to 
mm. in length. — Bull. Torr. Club, xxv. 138. WV. pubescens, Benth.
