312 BORAGINACEAE 



broad wings, the wings subequal all around, deltoid-toothed or erosulate or sub- 

 entire, the apex with a series of slender bristles, the sides with few scattered bristles 

 or none; nutlets on lower part of plant usually all unmargined. 



Valley plains, low hills and desert mesas, 100 to 3000 feet : inner South Coast 

 Range; upper San Joaquin Valley (mostly west side) ; Mohave and Colorado 

 deserts; San Bernardino Valley. South to Lower California, east to Arizona. 

 Apr.-May. 



Tax. note. — In its nutlet Pectocarya heterocarpa seems to be consistently, although narrowly, 

 distinct from Pectocarya penicillata. In Pectocarya penicillata, the wing of the nutlet is strongly 

 incurved at the middle on each side with the incurved portion destitute of bristles, with the oblique 

 apex densely bristly and the similar oblique base sparsely bristly or sometimes naked. In Pecto- 

 carya heterocarpa the wing is not incurved at the middle and is usually more or less scattered or 

 weakly uncinate-bristly on the sides or sometimes naked. The dorsal keel is sometimes conspicu- 

 ously and rather densely bristly (Painted Caiion, Mecca Hills, Jepson 11,647). As to the calyx- 

 lobes, they are unequal in Pectocarya heterocarpa with the smallest lobe standing next to the 

 axis ; but similar unequal calyx-lobes may be found in Pectocarya penicOlata.

4. P. linearis DC. Stems several to many from the base, diffuse or sometimes 

 erect, 2 to 8 inches long; herbage strigose; leaf -blades linear, 3 to 11 lines long; 

 nutlets divergent in pairs, oblong, surrounded by a wing shallowly cleft (about 

 half-way) on each side into 4 to 6 (or 8) short-lanceolate or triangular lobes or 

 teeth, the teeth conspicuous, tipped with a short stoutish uncinate bristle. 



Sandy flats and slopes, 900 to 2500 feet : eastern Mohave Desert ; Colorado Des- 

 ert. East to Arizona, south to Mexico ; Chile. Mar. -May. 



Geog. note. — The original form of the species is Chilean, but plants from our Sonoran region 

 correspond closely with plants from Chile. On the whole, this typical form seems rare In the 

 California deserts and there are here cited only the following. Eastern Mohave Desert : Hinkley 

 (n. of), CloTcey 6854; Calico Wash, n. of Daggett, Jepson 6705; Amboy Crater, Jepson 20,310;

 Well, e. San Diego Co., Jepson 17,114. 



Var. ferocula Jtn. Wing narrower, usually more deeply dentate or laciniate, the triangular 

 or subulate teeth more numerous, regular or often irregular, uncinate-tipped; wing sometimes 

 reduced, semi-obsolete or obsolete and its edge merely bristly. — Flats in canons and valleys or on 

 gravelly or grassy hillslopes, 50 to 2500 feet: South Coast Ranges (mostly in the inner range, 

 always back of the coast line) ; Sierra Nevada foothills in Kern Co.; central and western Mohave 

 Desert; Santa Barbara Islands; cismontane Southern California. South to Lower California; 

 also in South America.
