vided style) ; filaments from an ovoid-triangular base, false partitions entire, 
membranous; stipular glands evident, (as they are in my specimens of the 
following species). My specimens are very slightly glaucous. (15.) Gravel 
hills back of Santa Fé, N. Mex., at 7,050 feet altitude. 
Linum Beruanpier!, Hook.—Erect, annual, stem distinctly striated, 
slightly puberulent; lower leaves obtuse, upper slightly mucronate, longer 
on the average than in the preceding species, which it so closely resembles 
that I know of no way of distinguishing them, save by the character of the 
false dissepiments (as indicated by Dr. Engelmann in Pl. Wright. 1, pp. 25 
and 26), which, in L. Berlandieri, are membranous in the upper and inner 
half. Under head of L. Berlandieri, Dr. Engelmann alludes to a small form 
collected by Wright on the San Pedro River, which is apparently kept apart 
from L. rigidum, var. puberulum (collected on the Cimarron), only by the 
character of the false partition in the ovary, which is decidedly that of L. 
Berlandieri. I have the precise form (from Santa Fé) he alludes to (so 
far as can be determined from description), and have, from its partitions 
and ovate-triangular-based filaments, been obliged to put it under L rigi- 
dum, var. puberulum. Single specimens found by Dr. Loew. at Rancheiro 
Springs, Arizona. 
LinuM PERENNE, L.—Widely diffused over Nevada, Utah, Colorado, 
Arizona, and New Mexico, where it has been obtained by the Expedition; 
extending, besides, from the Arctic Ocean to Mexico and west to the Pacific.

* MALPIGHIACEX,—* Calyx 5-merous, persistent, segments rere biglandular. Petals 5, usually 
unghisalate, isostemonous, or diplostemonous, inserted either on the receptacle or on a hypogynons or

Ovary composed of 3 or 2 carpels, connate, or distinct at the top, of 3 or 2, 1-ovuled cells, ovule nearly

Petals clawed, fimbriate-ciliate. peasy 5, 2 perfect, 3 without anthers or the middle one of them with 
ant. and the lateral ones with imperfect anthers. Ovaries 3, connate to the axis, style

glands. Petals none. Anthers single and rudimentary. Ovaries 2, without styles. Nut solitary, either 
crestless, or with 1-3 slightly prominent dorsal crests, irregularly pyramidal 3-angled. Seed compressed, 
subreniform, testa membranous, cotyledons obovate, flattish, curved.—Slender, erect, branching shrubs,
