326 BORAGINACEAE 



Tax. note. — The assemblage of Arasinckia helleri, as here described, represents a group of 

 considerable diversity, especially in nutlet characters. This species has been referred to the north- 

 ern Amsinckia retrorsa Suksd. (Deut. Bot. Monats. 18:134, — 1900) by competent botanists, but 

 the Californian plants do not seem to be the same as authentic material of Amsinckia retrorsa 

 from Washington. Size of flowers separates this species from Amsinckia intermedia but is not 

 completely reliable. When growing with that species, however, Amsinckia helleri is different in 

 general aspect.

Amsinckia ldnabis Mcbr., Contrib. Gray Herb. 49:12 (1917), type loc. near San Mateo on

 ing-bristly and slightly puberulent ; leaves thickish ; leaf -blades linear or the upper lanceolate, 

 1 to 3 inches long, sessile or the lowest drawn down to a petiole-like base, strigose and puberulent 

 or the upper densely puberulent or somewhat velvety ; calyx-lobes strigose and with rusty bristles ; 

 corolla orange, 4 to 4% lines long, its tube broad, its limb 2^4 to 3% lines broad; nutlets carinate 

 on back, papillate and sometimes rugose. — Openly wooded or somewhat shaded slopes in the hills, 

 200 to 1500 feet, San Francisco Bay region : Bald Peak, Berkeley Hills, Hoover 975 ; San Pablo 

 Reservoir, Contra Costa Co., Hoover 3178; Lafayette, Contra Costa Co., Trac-y 13,196. Apr.-May.

8. A. spectabilis F. & M. Stem simple or branching from or near the base, 

 erect, or the branches at length decumbent, 1 to 2 feet long ; herbage light yellowish 

 green, setose-hispid, the hairs scattered or at least thin ; leaf -blades linear to ovate- 

 lanceolate or narrowly oblong, with erose-sinuate or entire margins, V2 to 2 inches 

 long, sessile or the basal narrowed to a broad-based petiole; spikes dense (or the 

 calyces at length discrete), 1 to 4I/2 inches long; cah-x with soft appressed rusty 

 hairs (at base of calyx whitish) and spreading-bristly, the lobes linear- or ovate- 

 lanceolate, 2 or 3 of the lobes partly united or all distinct ; corolla pale yellow, very 

 slender, 3 to 5^^ lines long, the limb 2V2 to ^^2 lines wide; folds in corolla-throat 

 low, finely hairy or sometimes glabrous; stamens exserted from corolla-tube into 

 throat ; nutlets rounded on back, murieulate or rugulose, or sometimes nearly 

 smooth, brown or blackish, Y2 to % line long. 



Sandy soil along the coast line, 5 to 200 feet : Mendocino Co. to San Diego Co. ; 

 Santa Barbara Islands. Mar.-June. 



Note on the nutlet. — In both Amsinckia spectabilis and its var. microcarpa the ventral side 

 of the nutlet exhibits a transverse ridge from the scar to the lateral angles ; or in some collections 

 this ridge is absent. This absence of the ridge does not seem to be definitely associated with any 

 other character.
