BORAGINACEAE (BORAGE FAMILY) 415 



dorsally toward the apex, rugulose or obscurely 'penicillate-roughened or 

 muriculate. Krynitzkia colifornica subglochidiata Gray. Frequent on moist 

 saline soil throughout our range. 



2. Allocarya Nelsonii Greene, Erythea 3: 48. 1895. Similar in size and 

 habit, the pubescence denser and the hairs with pustulate base; very pro- 

 fusely branched from the crown: inflorescence dense in fruit as well as in 

 flower: calyx open, the segments short: corolla inconspicuous: nutlets with 

 nearly basal scar, sharply keeled ventrally, a few sharp transverse or oblique 

 rugulae on the dorsal side, beset with minute hooked or forked hairs on the 

 ridges and obscurely papillose in the intervals. Known only from the type 

 locality, Silver Creek, Fremont county, Wyoming. 



7. CRYPTANTHE Lehm.* 



Slender, hirsute or hispid annuals, with narrow entire alternate leaves 

 and bractless (sometimes leafy-bracteate below) flowers in slender spikes or 

 racemes. Calyx more or less hispid, closely embracing the fruit and de- 

 ciduous with it. Corolla small, often inconspicuous. Nutlets 4, or by abor- 

 tion fewer, attached from the base upward usually nearly to the apex, smooth, 

 muriculate or tuberculate, sometimes with a slight dorsal ridge, the margin 

 sometimes acute or even winged. Krynitzkia Fisch. & Mey. in part. 



Nutlets smooth, light gray or mottled. 

 Sepals with a thickened rigid midrib. 

 Branched from the base. 



One nutlet more persistent .... . 1. C. Pattersonii. 



Nutlets all alike ..... 



Simple below, paniculately branched above 

 Sepals setose-hispid, midrib not noticeably thickened. 

 Sepals long-attenuate, the tips open-divaricate. 



Nutlets usually all maturing .... 



Nutlets solitary 



2. C. ramulosissima. 



3. C. Fendleri. 



4. C. flexuosa. 



5. C. gracilis. 



Sepals short, tips closed 6. C. Watsonii. 



Nutlets roughened or muricate, at least some of them. 



Nutlets dissimilar, one larger and smooth 7. C. crassisepala. 



Nutlets alike, one sometimes aborted 8. C. multicaulis. 



1. Cryptanthe Pattersonii (Gray) Greene, Pitt. 1: 120. 1897. Rough-hispid, 

 15-25 cm. high; the several stems from the base simple or sparingly branched: 

 leaves narrowly spatulate or linear: calyx hispid with pungent bristles, the 

 lobes linear-lanceolate and with noticeably thickened midrib: nutlets ovate- 

 acuminate, smooth, one of them disposed to be more persistent than the rest, 

 sometimes but one maturing, attached from the base to the middle or above. 

 Krynitzkia Pattersonii Gray. Plains and foothills of the eastern side of the 

 Rocky Mountains. 



2. Cryptanthe ramulosissima A. Nels. Erythea 7: 68. 1899. Densely 

 hispid throughout, closely and intricately branched from the base up, the 

 whole forming a subspherical mass 2-4 dm. in diameter: leaves small, nu- 

 merous, linear, the hairs with pustulate base: spikes uniserial, crowded, the 

 flowers in pairs: sepals linear, setose-hispid, midrib thickened at base, 5-6 mm. 

 long: nutlets all alike, smooth, subconical, 2 mm. long, ventral groove widen- 

 ing slightly into an open basal areola. Southern Wyoming. 



3. Cryptanthe Fendleri (Gray) Greene, Pitt. 1: 120. 1887. Erect, pan- 

 iculately branched from near the base, rather rigid, 2-3 dm. high: leaves 

 linear, 2-4 cm. long: spikes slender, bracteate at base: sepals narrowly linear 

 in fruit: nutlets narrowly ovate-acuminate, attached nearly to the apex, all 

 maturing and alike, brown, less than 2 mm. long. Krynitzkia Fendleri Gray. 

 Sandy plains in the Rocky Mountains and westward. 



* Besides the species described, several others are occasionally reported from our range, 

 among which may be named C. affinis, C. Torreyana, C. ambigua, etc. It seems doubtful 

 whether these species occur in our range. Fully developed material with mature nutlets is 

 likely to show that those so reported belong to one or the other of the species here de- 

 scribed, or else that they are new and yet undescribed.
