 unarmed, granulate-scabrous, 2 lines or more in length; marginal prickles flat and subulate. 



E. ursinum, GREENE. Nutlets with ovate disk nearly plane ; the marginal prickles short, 

 unequal, sometimes confluent into a wing-like border : stem and leaves hirsute or hispid : 

 fruiting pedicels sparse, longer than the fruit. Gray, Proc. Am. Acad. xvii. 224. Moun- 

 tains of New Mexico, Fendler (633), Greene, and of S. Arizona, Lemmon. Also S. Utah,

E. floribundum, LEHM. Nutlets with dorsal disk deltoid and w^ith a strong midnerve or 

 keel ; margin armed with long flat prickles : herbage soft-pubescent or the stem soft-hir-

H 1 Perennials, usually larger-flowered: pedicels mostly longer than the fruit.

 ovate dorsal disk, but these shorter than the flattened subulate and sometimes confluent ones of 

 the margin : leaves usually lanceolate. 



E. diffusum, LEHM. (not of p. 189). Soft-pubescent, or at most soft-hirsute (occasionally 

 some papillosities on the leaves) : corolla bright blue, varying to white, one-third to two- 

 thirds of an inch in diameter : marginal prickles of the nutlets subulate and very flat, nearly 

 as long as the width of the dorsal disk, this beset with a few small glochidiate processes : 

 scar nearly central. Gray, Proc. Am. Acad. xvii. 225. E.Jloribundum, p. 189, in part.

E. hispidum, GRAY. Hispid with spreading papillose-based hairs: leaves green; lowest 

 broadly lanceolate ; upper ones short and small : racemes lax : corolla " greenish white," 

 2 or 3 lines in diameter : marginal prickles of the obcompressed nutlets small and narrow, 

 much shorter than the width of the oval or ovate and either sparsely or copiously glochidi- 

 ate dorsal disk, their bases confluent into a thin margin or distinct wing (which is some- 

 times reflexed or cup-like) ; inner face smooth and lucid, with scar almost central. Proc. 

 Am. Acad. xx. 259. E. diffusum, var. J/i*j>idnm, Gray, Proc. Am. Acad. xvii. 225. Rocky

E. ciliatum, GKAY. Cinereous with a much appressed pubescence, and bristly-hirsute,

 or more high : corolla rather large, blue or violet : fruit unknown. Proc. Am. Acad. 1. c., 

 excl. what relates to Ci/norjlossitm Ilmrnrdi. Cynoglossum ci/itttum, Dougl. in herb. Hook.,

-H- -H- Corolla short-sal verform, i. e. with tube (surpassing the calyx) about the length of the 

 ample lobes: nutlets armed all over the back with long glochidiate prickles quite like those of 

 the margins: leaves spatulate-oblong to lanceolate or the upper ovate-lanceolate, thickish in age, 

 with prominent midrib but no obvious veins or nerves. 



E. Californicum, GRAY, 1. c. E. diffusum, of p 189, not of Lehm. E. nervosum, Kellogg,
