364 BORAGINACEAE 



The following clsmontane variety differs from the species only in the shape of the nutlet and 

 in that feature only dubiously or uncertainly, but is well segregated geographically from the 

 intramontane-transmontane species. 



Var. vallicola Jepson nom. n. Stems several to many from the base, 4 to 14 inches high ; 

 herbage asceuding-hispid; spikes 2 to 8 inches long, loose; corolla 1 to 1% lines broad; nutlets 

 ovate, the dorsal side closely (or sometimes openly) and irregularly rugulose transversely and 

 shortly keeled towards the apex, or the keel obsolete, the grooves or interspaces smooth or some- 

 times with a few fine papillae; ventral side keeled and obliquely rugulose, the scar ovate or linear, 

 obliquely basal. — Moist flats in heavy adobe or rich soils, 10 to 4700 feet; throughout cismontane 

 California back of the coast line. North to Oregon. Apr. -June.

 (1932). This differs from AUocarya cusickii var. vallicola in having barbed bristles on the 

 nutlets. Nutlets with minute scabrous points sometimes occur in A. cusickii var. vallicola ace. 

 R. F. Hoover and the plants are then hardly distinguishable from A. hispidula except by habit 

 and occurrence at a low altitude. 



12. A. trachycarpa Greene. Stems several or many from the base, diffuse or 

 decumbent, 4 to 17 inches long ; herbage thinly ascending-hispid; leaf -blades linear- 

 oblanceolate, 1 to 2 inches long ; racemes leafy -braeteate throughout or nearly so ; 

 calyx-segments spreading; corolla % to IY2 lines broad; nutlets broadly ovate, 

 transversely and mostly rough-rugulose or tuberculate-rugulose, the rugae distinct 

 or connected irregularly by short rugae ; dorsal interspaces or areolae finely tuber- 

 eulate; ventral side obliquely rugulose, papillate in the grooves, the marked keel 

 extending down to the scar ; scar deltoid, deltoid-ovate or deltoid-orbicular, very 

 near base but lateral, often markedly excavate, 1 3 length of nutlet, the bordering 

 flange broad. 



Valley floors, 10 to 1000 feet : Great Valley from Shasta Co. to Merced Co. ; 

 South Coast Ranges from Contra Costa Co. to San Luis Obispo Co. ; coastal Los 

 Angeles Co. Mar.-May.
