BORAGE FAMILY. 44;> 



lung; covoUa 2 or 3 lines broad; nutlets 1 line long, muricate- 

 papillose, and somewhat rugose on the back; ventral ghjove and its 

 basal bifurcation mostly closed; lateral angles acutish, distinct. 

 Mt. Diablo Range, from near Antioch southward. Apr. 



3. C. Jonesii (Gray) Greene. Erect, strict, 7 to 14 in. high, leafy 

 below; lateral spikes from near the base or above the middle short, 

 often sessile, the terminal spikes longer in a, rather close panicle; 

 corolla less than 1 line broad in dried ■specimens; sepals linear, 

 obscurely unicostate, bristly-hispid, in fruit about 1 line long, 

 slightly surpassing the rough-papillate ovate nutlets which are 

 acutely^angled laterally and little more than J line long; ventral 

 groove mostly closed and forked below. 



Sonoma; Mt. Tamalpais; Santa Cruz, July 1, 1881, and Soledad, 

 Jlay 20, 1882, ^^. E. Jones, who first collected it. Nutlets some- 

 times smooth and concave on either side of the ventral groove. 



4. C. micromeres (Gray) Greene. Slender, rather widely 

 branched above the base, 7 to 9 in. high, rough-hirsute almost 

 throughout; spikes mostly terminal or subterminal, not dense, 2 to 4 

 in. long; nutlets similar to the preceding, -little more than \ line 

 long, slender papillate {or on either side of the ventral groove concave 

 and either papillate or smooth). 



Santa Cruz, Jones; Sierra IToothilU at Mokelumne Hill, Rntlnn, 

 the spikes after the fall of the flowers obscurely flexuous. 



5. C. microstachys Greene. At first erect and 3 or 4 in. high, 

 later diffuse with ascending or reclining branches f to 2 ft. long, 

 bristly throughout; splices slender, 4 to 6 in. long, rather densely 

 flowered; sepals less than 1 line long, very hispid-bristly; nutlet 1, 

 brown, smooth, ovate, with long and slightly contracted apex, 

 slightly compressed but not angled laterally, f to 1 line long; groove 

 closed, with a minute fork at base. 



Santa Cruz Mts., June 20, 1896, Setchell and Jrjjsan; Vaca 

 Mountains, May, 1892. 



6. C. flaccida (Dougl.) GreenS. Strictly and rigidly erect, with 

 few ascending branches at the top, f to \\ ft. high; leaves linear; 

 spikes 2 to 4 in. long, at length not crowded; corolla nearly or quite 

 1 line broad; fruiting calyx IJ lines long, appressed to the rachis, its 

 narrowl}' linear segments thickish at base, connivent above, neai-ly 

 twice as long as the nutlet, hispid and bearing toward the base a 

 deflexed tuft of bristles; nutlet rostellate-acuminate at apex, the 

 groove enlarged below but not forked. 



Common on low dry gravelly hills of the inner Coast Ranges: 

 Sierra Nevada. Apr.-May. 



7. C. leiocarpa (F. & M.) Greene. Commonly branched from 

 the base, with many erect or ascending branches, 5 to 13 in. long; 

 branches mostly simple below, branching above, and bearing many 

 spikes which are often more or less congested; spikes leafy-bracted, 

 rarely bractless, the terminal longer and interrupted, the lateral short 

 and glomerate; sepals short-linear, hispid-bristly; nutlets usually 4,
