margined petioles : racemes numerous, commonly geminate and in fruit rather 

 strict: nutlets with elongated triangular back naked, merely scabrous; and 

 the margin armed with a close row of flat subulate prickles, their bases often 

 confluent. — E. deftexum, var. fioribundum, Watson. From New Mexico and 

 California northward to British America. 



2. E. eiliatum, Gray. A foot or more high, canescently hirsute, the hairs 

 on the lower part of the stem relrorse : leaves tomentose-hirsute, ciliate, sessile, lin- 

 ear ; the lower 4 inches long and 2 lines wide ; the upper an inch long : racemes 

 subcorymbose : fruit unknown. — Proc. Am. Acad. xvii. 225. Cynoglossum 

 eiliatum, Dougl. Tributaries of the Columbia and eastward to the Rocky

*,* Spikes leafy-bracteate : pedicels erect or merely spreading: calyx-lobes mostly 

 exceeding the fruit, becoming foliaceous and often unequal: scar of the nutlets 

 long and narrow: plants with rough or hispid pubescence: leaves linear, lan- 

 ceolate, or the lower somewhat spatulate. 



3. E. Eedowskii, Lehm. Erect, a span to 2 feet high, paniculately 

 branched : nutlets irregularly and minutely muricately tuberculate ; the mar- 

 gins armed with a single row of stout flattened prickles, which are not rarely 

 confluent at base. 



Var. occidentale, Watson. Less strict, at length diffuse, and the tuber- 

 cles of the nutlets sharp instead of blunt oi roundish. — Bot. King Exp. 246. 

 From Arizona and Texas northward. 



Var. cupulatum, Gray. Prickles of the nutlet broadened and thickened 

 below and united into a wing or border, which often indurates and enlarges, 

 forming a cup, with margin more or less incurved at maturity, sometimes only 

 the tips of the prickles free. — Bot. Calif, i. 530. From Nevada to Texas and 

 Nebraska. With the preceding form.

1. O. nana, Gray, var. aretioides, Gray. Densely cespitose in pulvinate 

 tufts, rising an inch or two above the surface, densely villous with long soft 

 white hairs which are sometimes papillose-dilated at base : leaves varying from 

 ovate to lanceolate : flowers terminating very short densely leafy shoots, or 

 more racemose on developed few-leaved stems : nutlets with a pectinate-toothed 

 or spinulose dorsal border. — Loc. cit. Eritrichium nanum, Schrad., var. areti- 

 sides, Herder. E. villosum, var. aretioides, Gray. Highest alpine, Colorado, 

 Utah, Wyoming, and northward. 



2. O. Howardi, Gray. Densely cespitose, sericeous-canescent with ap- 

 prised pubescence : leaves spatulate-linear, 5 to 8 lines long, mostly crowded 

 on the tufted branches of the caudex ; the flowering stems 3 to 4-leaved :
