3. E. angustifolium Nutt. Shrub 2 to 3 feet high, the branehlets rather densely 

 clothed with leaves ; leaf-blades narrowly linear, entire or dentate, light green and 

 glabrous or nearly so above, white-tomeutose beneath, narrowed towards the base 

 but scarcely petioled, 2 to S^/o inches long; panicle 2i/2 to 6 inches long; calyx 

 sparsely hirsutulous, 1 to ly^ lines long; corolla white, narrowly campanulate, 2 to 

 3 lines long. 



Dry slopes, 4000 to 6000 feet : New York Mts., eastern Mohave Desert. East to 

 Utah, south to Lower California. May- Aug. 



Distrib. note. — In southern Nevada, in southern Utah and in Arizona Eriodictyon angusti- 

 folium is frequently met vrith in mountain ranges and extends into Lower California at least as 

 far south as San Pedro Martir. In California the occurrence of this species is probably of limited 

 extent, since it is kno^vn thus far only in Keystone Canon, New York Mts. (Wolf ^ Everett 9025). 



Refs. — Eriodictyon angustifolium Nutt., Jour. Acad. Phil. ser. 2, 1:181 (1848), type loc. 

 "Sierra of Upper California," undoubtedly Arizona, since Arizona is the only region where this 

 species is found on the route traversed by Gambel, the original collector of it; Gray, Sj-n. Fl. ed. 

 2,2:176 (1886). 



4. E. capitatum Eastw. Shrub ; leaves fascicled toward ends of branches, the 

 blades narrowly linear, with strongly revolute margins, sessile, 1^2, to 2 inches long; 

 peduncles slender, not exceeding the subtending leaves, terminating in a densely 

 congested small (% inch wide) flower-cluster; calyx villous; corolla lavender, 4 

 lines long, villous, the upper part of the lobes glabrous; filaments unequally in- 

 serted below the middle of the corolla-tube, the adherent part narrowly winged 

 at base. 



Brushy ravines, 100 to 500 feet : Purisima Hills, north side of lower Santa Ynez 

 River valley, near the ocean, Santa Barbara Co. May-Aug. 



Endemism note. — Eriodictyon capitatum is an entirely peculiar species of the narrow endemic 

 category which is restricted to a very limited area on the Burton mesa, west end of the Purisima 

 Hills. The original area where it is found probably does not exceed a diameter of two or three 

 miles and lends to this singular Eriodictyon a special interest. The following collections are 

 cited: Pine Canon, Burton Mesa, Howe; ravine approaching Burton Mesa, McMinn 4347. Very 

 recently a station has been discovered in Cojo Caiion aec. M. Van Rensellaer. 



Ref. — Eriodictyon capitatum Eastw., Lfita. West. Bot. 1:40 (1933), type loc. Lompoc (5 

 mi. n.), on road to Casmalia, Santa Barbara Co., Hoffmann. 



5. E. crassifolium Benth. Yerba Blanco. Bluish-gray shrub, 4 to 6 (or 12) 

 feet high; herbage covered with a dense felt-like tomentum, the young leaves often 

 snow-wliite, at maturity usually dull or greenish; leaf-blades oblong to oval, felt- 

 like, thick and rigid, erenate, 2 to 4 inches long ; petioles about I/4 inch long; panicle
