and terminal, forming a long, somewhat contracted panicle^ S-S-flowered^ at first circlnate ; 

 -, flowers approximated, on short pedicels. Segments of the calyx linear^ somewhat hispidlj 



pilose. Corolla white, abont one-third longer than the crIjx ; the tube very short ; horde 

 much dilated. Stamens scarcely exserted. Nutlets nearly a line long, the face acutely arinate, 

 and a small prominence near the base^ where it is attached to the style; the hack strongly convex.

Eritrichium micrantiium (n. sp): annuum, pusillum, canescenti-hispidum; caule e basi 

 , ramosissimo ; foliis linearibus obtusis ; racemis brevibus longe bracteatis ; floribus confertis,

angulo interne prominente sulcato. Sand hills, Frontera, Texas, and in other places along 

 the Rio Grande, March — April ; Tkurher. {Wrigitt^ No. 1565.) Stem 2-4 inches high, much 

 branched from the base, and apparently diffuse when old ; the branches very slender. Leaves 

 3-4 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 sulcate 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.

 Thurher. Canon of Guadalupe Mountain, Sonora ; Capt. E. K. Smith. The segments of the 

 calyx are much elongated after flowering, when they become almost subulate. One of the nutlets 

 is sometimes larger and smoother than the others. Differs from E. crassisepalum in the longer, 

 denser, and naked racemes ; in the nutlets being wholly or nearly homomorphous, oblong, and 

 only very minutely scabrous. 



Eritrichium Chorisiais^um, DC. Prodr. 10,^. 130? 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 terebinth ine 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.
