5. KBYWITZKIA, Fisch. & Meyer. 



Annual herbs or some perennials, with white and mostly small flowers. 

 Includes Eritrichium § Krynitzkia, and § Eueritrichium Myosotidea, Gray, 

 Synopt. PI. ii. 191. — Gray, Proc. Amer. Acad. xx. 264. 



§ 1. Nutlets more or less ovate, rugose, sometimes keeled dorsally or ventrally, 

 attached at the base by a very small areola either to a depressed or little ele- 

 vated gynobase: low and mostly diffuse or spreading annuals, sparsely or 

 minutely hirsute : leaves linear : flowers very small (a line long). — Myoso- 

 tidea. 



1. K. Californiea, Gray. Slender, more or less hirsute: stems flower- 

 ing from near the base : flowers almost sessile, most or all the lower accom- 

 panied by leaves or bracts, at length scattered : nutlets transversely rugose 

 and minutely scabrous or smooth ; the scar almost basal. — Loc. cit. 266. 

 Eritrichium Californicum, DC. Spring_ or muddy ground, from Wyoming 

 and New Mexico to California and Oregon. 



Var. subgloehidiata, Gray. Slightly succulent: lower leaves inclined 

 to spatulate: nutlets when young minutely more or less hirsute or hispid, 

 especially on the crests of the rugosities, some of these little bristles becoming 

 stouter and appearing glochidiate under a lens. — Bot. Calif, i. 526. Wyo- 

 ming and Colorado to California. 



§ 2. Nutlets never rugose, angulate or sulcale ventrally, with convex back neither 

 keeled nor angulate, attached from next the base to the middle or even to the 

 apex to the elevated gynobase : corolla small, ils short tube not exceeding the 

 calyx; throat either naked or with appendages not exserted: annuals, with 

 flowers scorpioid-splcate. — Eukrynitzkia. 



* Calyx early circumscissile , the 5-cleft upper porlion falling away, leaving a 



membranaceous base persistent around the fruit : nutlets ovate-acuminate, 

 smooth or minutely punctilulate-scabrous, attached by u, narrow groove (with 

 transverse basal bifurcation) for nearly the whole length to the subulate gyno- 

 base : corolla with naked and open throat. 



2. K. eircumscissa, Gray. Depressed-spreading, very much branched, 

 an inch to a span high, whitish-hispid throughout : narrow linear leaves (J to 

 £ inch long) and very small flowers crowded, especially on the upper part of 

 the branches., — Loc. cit. 275. Eritrichium a'rcumscissiim, Gray. Dry plains, 

 Wyoming and Utah to California and Washington. 



* * Calyx not circumscissile, 5-parled, conspicuously and often pungently hispid; 



the whole calyx (or short pedicel) often inclined to disarticulate at maturity, 

 forming a sort of bur loosely enclosing the nutlets. 

 t- Sepals never very narrow, with a strong rigid rib : nutlets mostly dull : diffusely 

 branching rough-hispid herbs. 



3. K. crassisepala, Gray. A span high, very rough-hispid : leaves 

 oblanceolate and linear-spatulate : persistent calyx very hispid with yellowish 

 or fulvous bristles ; its lobes greatly thickened below in fruit : nutlets ovate, acute, 

 dissimilar, 3 of them muricate-granulate and one larger and smooth or nearly so, 

 fixed to the conical-pyramidal gynobase from base to middle. — Loc. cit. 268. 

 Eritrichium crassisepalum, Torr. & Gray. From New Mexico and W. Texas
