BORAGE FAMILY. 349 



loaves few, ovate or ovate-oblong, 2 to 3 or 4 lines long; spikes 1 to 3 in. long, 

 comparatively few-flowered; calyx deeply cleft, at first rusty yellowish, at length 

 pale, sometimes imperfectly circumscissile ; nutlets minute (% line long), 

 shining and enamel-like on the back, smooth but papillate-scabrous on the 

 lateral angles and often also on the rugae; rugae transverse, straight, smooth 

 and low, separated by very fine lines. — (Eritrichium tenellum Gray.) 



Santa Cruz Mts. (Muhl., iii, 118) ; North Coast Eanges; Sierra Nevada, Un- 

 common in our region. 



3. P. nothofulvus Gray. Plants erect or suberect, 1 to 2y 2 ft. high; 

 stems 1 to several from the depressed rosulate tuft of leaves, branching mostly 

 above, the branches widely spreading or erect ; herbage silky-villous, the hairs 

 very reddish when young, especially on the calyx and sometimes on the leaves; 

 leaves oblong-ovate or lanceolate, those of the radical tuft oblong-ovate or 

 oblanceolate ; spikes leafless; calyx cleft to the middle, l 1 /-* lines long, in fruit 

 circumscissile below the middle, the upper part falling away and leaving the 

 persistent base about the nutlets; corolla 2 to 3 lines broad. 



Hills and mountain sides of the North Coast Eanges (St. Helena, Vaca Mts.) ; 

 Sierra Nevada foothills. Mar. -May. 



4. P. canescens Benth. Branches long and straggling, nearly or quite 

 simple, y 2 to l 1 /^ ft. long, loosely flower-bearing and leafy nearly throughout, 

 or quite leafless above and spicate; pubescence pale, sof t-villous ; leaves oblong 

 to linear or lanceolate ; calyx cleft to below the middle, the segments broadly 

 lanceolate, in fruit 2 to 3 lines long; nutlets 1 line long, incurved-connivent, 

 rugose-reticulate, the areola longer transversely, and the lateral angles very 

 distinct. — (Eritrichium canescens Gray.) 



Low open hills of the Coast Eanges and Sierra Nevada. Apr. Calyx in 

 fruit circular-depressed (the tips of the segments connivent over the nutlets), 

 in age deciduous, the very short stubby pedicel persistent. Plants sometimes 

 erect. 



5. AMSINCKIA Lehm. 



Annuals with rough-hairy herbage, the hairs commonly with pustulate-dilated 

 base, which is often conspicuously hardened or granular. Flowers yellow, in 

 elongated spikes. Sepals 5, or 4 or 3 through the more or less complete union 

 of two into one. Corolla salverform, the throat somewhat funnelform and 

 with more or less distinct folds, but destitute of crests or processes. Nutlets 

 crustaceous, triquetrous or ovate-triangular, smooth or rough. Cotyledons 

 deeply 2-parted. (Wm. Amsinck of Hamburg, patron of the Botanic Garden 

 in that city.)

 with rli*- broadly-ovate foliaceous segments aboul twice the length of the nut- 

 lets; corolla small, orange-yellow; nutlets broadly ovate, abruptly acute, not
