BOTANY.

rigid whitish hairs: towards the summit of the numerous short branches they are much 
crowded, so as to appear fasciculate. Flowers sessile, 2-3 lines long. Calyx hispid, like the 
leaves; the tube somewhat indurated in fruit. Stamens unequal, included. Style cleft about 
one third of the way down, about as long as the stamens. Nutlets scarcely one third of a line 
in diameter, two or three of them usually abortive, of a dull gray color, roughened with very 
minute papilllae; the endocarp crustaceous and brittle.—Nearly allied to Tiquilia of Per- 
soon, a genus very distinct from Coldenia, to which it was referred as a subgenus, with a mark 
of doubt, by De Candolle. Both genera seem to he more allied to the tribe Borageaa than to 
Ehretieas. *

Eritrichium crassisepalum, (n. sp.): annual, very hispid with spreading hairs; stem branch¬ 
ing from the base; the branches ascending; leaves obovate-lanceolate, rather obtuse; racemes 
bracteate (except the upper portion); flowers on short pedicles; fructiferous calyx ventricose at 
the base, closed and contracted above the middle, the segments thickened and indurated on the 
back.; nutlets heteromorphous, ovate, acute, convex on the back, three of them muriculate- 
granulate, the fourth larger and nearly or quite glabrous. On the Pecos, Llano Estacado, &c.; 
in sandy soil; March. A common species in Western Texas and New Mexico. It was found 
by Fremont on the Upper Platte. It is the same as No. 640 of Fendler’s New Mexican collec¬ 
tion. The flowers are white and variable in size, being in some specimens minute, and not 
much longer than the calyx, and in others quite conspicuous, as in the section Cryptantha of 
Alph. DC. This species, however, belongs to the section Rutidocaryum, as does the fol¬ 
lowing. 
Eritrichium pusillum, (n. sp.): annual, dwarfish, hispidly pilose; stem branching from the 
base; leaves spatulate-linear; racemes many-flowered, ebracteate; flowers sessile, approximate ; 
calyx deeply 5-parted, the segments lanceolate and very hispid; corolla about as long as the 
tube of the calyx; nutlets ovate-subtriangular, acute, verrucose-granulate on the back. Rio 
Pecos to Llano Estacado ; March. It is the same as No. 1571 of Mr. Wright’s New Mexican 
collection. A very small species, being not more than two or three inches high even in fruit. 
It either branches from the base, or-throws up numerous simple stems, which are somewhat 
spreading. The flowers are minute and white. The nutlets are light brown, scarcely one third 
of a line long, and roughened with somewhat distant granules or papillse*. 
Echinospermum patulum, Lelim.; DC. Prodr. 10, p. 137. Common in Western Texas. 
Echinospermum strictum, Nees, in Maximill. Trav. App. Cynoglossum pilosum, Nutt. Gen. 
1, p. 114? Llano Estacado; March to April. The nutlets are armed with 6-8 strong and short 
prickles on each side of an obtuse border surrounding a deep open cavity in front of each. Some¬ 
times one of the nutlets is of a different form from the others. De Candolle refers Nuttall’s 
Cynoglossum pilosum to Pectocarya pencillata, not from having seen the plant, but because it 
was said to resemble so strongly the figure of that species in the Flora Peruviana ; but Mr. Nut- 
tall (in Plant Gamb.) says it is “a true Myosotis,” or rather an Eritrichium; so that it is 
wholly unlike Pectocarya.
