§ 5. PsEUDOKRYNiTZKiA. PerenniiiLs 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. Mritrichium § Krynitzkia Pseudo-Myosotis (excluding the two 

 winged species), p. 196. 



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

 >harp-margined nutlets. 



K. racemosa, Greene. E.xcessively branched from the jtersisteut base, hispid with 

 spreading bristles, a foot or two higli : branches slender: leaves narrowly linear, half-incli 

 to iuch long : flowers very numerous, loosely racemose-paniculate and with ouly occasional 

 bracts; the lower comnumly on spreading pedicels which nearly ecpuil or exceed the calyx, 

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

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

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

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

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

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

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



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

 JL. Jamesii, Gray, 1. c., is Eritrichium Jamesii, Torr., p. 19fi. Extends even to S. E. 

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

 Mexico, witli o])aque and rugulose (instead of smooth and j)olished) nutlets. 



-1— -1^ 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 cxserted : sejjals lanceolate: anthers ob- 

 long: nutlets ovate, more or less obconipressed, scabrous or tubercuhite on the Itack, ver}' acute- 

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

 an areolar dilatation. 



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

 radical leaves somewhat canesccnt by a fine pubescence between the pa))illose-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
