and terminal, forming a long, somewhat contracted panicle, 3—8-flowered, at first circinate ; 
flowers approximated, on short pedicels. Segments of the calyx linear, somewhat hiepidly 
pilose. Corolla white, about one-third longer than the calyx ; the tube very short; border 
much dilated. Stamens scarcely exserted. Nutlets nearly a line long, the face acutely carinate, 
and a small prominence near the base, where it is attached to the style; the back strongly convex.

April. 
ERITRICHIUM MICRANTHUM (n. sp.): annuum, pusillum, canescenti-hispidum; caule e basi 
ramosissimo ; foliis linearibus obtusis; racemis brevibus longe bracteatis; floribus confertis, 
corolla minutissima, fauce nudo; nuculis oblongis acutiusculis glaberrimis dorso convexis 
angulo interno prominente sulcato, Sand hills, Frontera, Texas, and in other places along 
the Rio Grande, March— April ; Thurber. (Wright, No. 1565.) Stem 2-4 inches high, much 
branched from the base, and apparently diffuse when old ; the brgnches very slender. Leaves 
8-4 lines long, and scarcely more than half a line wide. Racemes at first capitate and crowded 
with short leafy bracts, unfolding gradually, but never more than half an inch long, the 
flowers so close together as to be imbricated, with foliaceous bracts at the base longer than 
the calyx. Segments of the calyx linear. Corolla less than a line in length, separating early from 
the base, but remaining on the flower like a calyptra, the tube narrow, and about as-long as the 
calyx ; no traces of appendages ; the lobes small and ovate. Stamens inserted about the middle 
of the corolla-tube, nearly sessile. Nutlets about one-third of a line long, narrowly oblong, | 
Shining, apparently adhering to the column (which is very broad at the base,) by the whole 
length of the suleate inner angle. This species is allied to Krynitzkia, and also to the section 
Cryptantha of Eritrichium, differing from the first in the persistent calyx, and in wanting the 
appendages of the corolla, from the latter in the homomorphous flowers and smooth nutlets.

Thurber. Cañon of Guadalupe Mountain, Sonora; Capt. E. К. Smith. The segments of the 
calyx are much elongated after flowering, when they become almost subulate. One of the nutlets 
is Rcs larger and smoother than the others, Differs from E. crassisepalum in the longer, 
, and naked racemes ; in the nutlets being wholly or nearly homomorphous, oblong, and 
only very minutely scabrous. 
ERITRICHIUM OHORISIANUM, DC. Prodr. 10, p. 180? Grassy hills near San Luis Rey, and on 
mountains east of San Diego, California, March—June; Parry. The plant from the former 
station is much larger, with radical leaves 3 inches long and 3-4 lines wide. Specimens laid in 
the herbarium give out, after some time, a purplish material, which leaves the imprint of the 
plant on the paper. The coloring matter is of a resinous or terebinthine nature and is quite 
soluble in alcohol, so that it is not a kind of indigo. It is contained in cells which are situated 
along the margin and on each side of the midrib. In the dried plant the color is of a bright 
red. We have a strong suspicion that E. Californicum, E. Chorisianum, and E. Scouleri are 
not distinct,
