or the leaves hispidulous; leaves of the radical tuft oblong, acute 

 or obtuse, J to 1 in. long; cauline leaves 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 rug*; rug* transverse, 

 straight, smooth and low, separated by very fine lines. 



Kaweah Kiver, southern Sierra Nevada, Eastwood; Napa Moun- 

 tains, Jepson; northern California. Uncommon in our region. 



3. P. nothofulvus Gray. Plants erect or suberect, 1 to 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 only when young, espe- 

 cially 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 only to the middle, 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. 



Hill and mountain sides: St. Helena, Napa Co.; Vaca Mountains: 

 Sierra Foothills. Mar. -May. 



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

 or quite simple, \ to 1£ ft. long, loosely flower-bearing and leafy 

 nearly throughout, or the spike nearly or quite leafless; pubescence 

 pale, soft-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. 



Livermore Valley; English Hills, Solano Co.; French Camp, Sierra 

 Foothills; Marysville Buttes; first collected by Hartweg in the Upper 

 Sacramento Valley. Apr. Calyx in fruit circular-depressed (the 

 tips of the segments connivent over the nutlets), in age deciduous, 

 the very short 6tubby pedicel persistent. Plants sometimes erect. 



5. AMSINCKIA Lehm. 

 Annuals with rough-hairy herbage, the hairs commonly with 

 pustulate-dilated base, 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. Style filiform. Nutlets crusta- 

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

 deeply 2-parted. [Wm. Amsinck of Hamburg, patron of the 

 Botanic Garden in that city.) 



Nutlets much flattened on the back, with coarse granulations 



1. A. tesxctata. 



Nutlets beset with prickly projections 2. A,, echinata. 



Nutlets not prickly. 

 Nutlets carinate on the back, granulate and rugose.
