 Myosotis in Eritrichium, p. 195. 



K. pterocarya, Gray, 1. c, is Eritrichium pterocaryum, Torr., p. 195. The variety pecti- 

 natum too inconstant and variable to separate. The same of A", cycloptera, Greene, Bull. Calif. 

 Acad. i. 207, proposed for specimens with the four nutlets winged all round the base and 

 inner faces not muricate ; characters which do not hold out. 



K. holoptera, Gray, 1. c, is E. holopterum, Gray, p. 196. This and the following have 

 the habit of the coarser species of the next section. (The plant referred to under this spe- 

 cies in Proc. Am. Acad. 1. u. is K. Utahensis.) 



K. setosissima, Gray, I.e., is Eritrichium setosissimum, Gray, p. 196. — S.Utah, Ward, 

 Palmer, and N. Arizona, Eusby, Lemmon. 



§ 5. Pseudokrynitzkia. Perennials or biennials, of coarse habit : nutlets 

 triquetrous or trigonous, with lateral angles acute but not wing-margined, at- 

 tached for most of their length to a commonly subulate gynobase : corolla with 

 prominent fornicate scales or folds in the throat, and at base within usually 10- 

 squamellate or annulate-glandular. — Proc. Am. Acad. xx. 276, excluding an 

 annual species. Eritrichium § Krynitzhia Pseudo-Myosotis (excluding the two 

 winged species), p. 196. 



* Ambiguous species, small-flowered, of Eukrynitzlcia habit, but suffrutescent-perennial and with 

 sharp-margined nutlets. 



K" . racemosa, Greene. Excessively branched from the persistent base, hispid with 

 spreading bristles, a foot or two high : branches slender : leaves narrowly linear, half-inch 

 to inch long : flowers very numerous, loosely racemose-paniculate and with only occasional 

 bracts ; the lower commonly on spreading pedicels which nearly equal or exceed the calyx, 

 upper subsessile : limb of the corolla only a line broad : fructiferous calyx a line or two 

 long, setose-hispid: nutlets (usually only one or two maturing, a line and a half long) tri- 

 gonous, with ovate-lanceolate outline of the back, and narrow acute margins, all the faces 

 sparsely papillose, the ventral groove open and gradually widening to the base. — Bull. 

 Calif. Acad. i. 208. K. ramosissima, Gray, 1. c. 277, as to all the char, and the Parish plant. 

 Eritrichium racemosum, Watson, Proc. Am. Acad. xvii. 226. — Desert regions, in canons, 

 S. E. California, Parish, and Cantillas Mountains on the borders of Lower California, Orcutt. 

 Arizona, in the Grand Canon of the Colorado, A. Gray. 



* # Genuine species, more robust, larger-flowered, broader-leaved, and with mostly thyrsoid- 

 glomerate inflorescence ; the spikes more or less evolute in age, here and there bracteate: flow- 

 ers in some heterogone-dimorphous, in the last (anomalous) species yellow ! 



-I— Nutlets (smooth) each a quadrant of an oblate sphere: perennial, short-flowered. 

 TC _ Jamesii, Gray, 1. c, is Eritrichium Jamesii, Torr., p. 196. Extends even to S. E. 

 California. And K. Palmer i, Gray, 1. c, already mentioned, is an allied species of Coahuila, 

 Mexico, with opaque and rugulose (instead of smooth and polished) nutlets. 



-i_ -l_ Nutlets flat or barely convex on the back, the four together pyramidal. 

 ++ Short-flowered, that is, tube of corolla not surpassing the calyx and shorter than its (2 or 3 lines 

 wide) limb ; faucial appendages semiglobose and little exserted : sepals lanceolate : anthers ob- 

 long: nutlets ovate, more or less obcompressed, scabrous or tuberculate on the back, very acute- 

 margined, the slightly elevated ventral face traversed by a slender groove terminating below in 

 an areolar dilatation. 



= Biennial, 2 or 3 feet high, very hispid with widely spreading long bristles. 

 K. virgata, Gray, 1. c, 279, is Eritrichium glomeratum, var. virgatum, Porter, p. 196, 



with syn. 

 K. glomerata, Gray, 1. c. 279, is E. glomeratum, DC, p. 196, the type, with syn. Only 

 radical leaves somewhat canescent by a fine pubescence between the papillose-based bristles : 

 nutlets thicker than in the preceding, more corrugate and carinate on the back, and nar- 

 rower at the obtusish apex.— Plains along the eastern base of the Rocky Mountains, from 

 Saskatchewan to New Mexico, and N. Arizona to "Washington Terr.
