PHACELIA FAMILY 289 



ceous or firm, mostly dentate and petiolate. Flowers in a terminal, usually naked, 

 panicle of scorpioid cjines ( or the panicle sometimes condensed into a head) . Calyx- 

 lobes narrowlj- linear, not dilated above. Corolla funnelform to eampauulate, its 

 tube without scales. Stamens little or not at all exserted, unequal or sometimes 

 subequal, mostly unequally inserted at middle of corolla-tube or below, the fUaments 

 sparsely hirsute, their adnate portion (below insertion) usually in relief on the 

 tube. Ovary nearly or quite 2-eelled by the meeting of the protruded plate-like 

 placentae in the axis; styles 2, distinct. Capsule small (1 to 2 lines long), both 

 loculieidal and septicidal, thus 4-valved, each valve with a short beak or acumina- 

 tion, each closed on one side bj^ the adherent half-partition and usually 1 or 2 

 (rarely 3)-seeded. — Species 11, western North America. (Greek erion, wool, and 

 diktuon, a net, by reason of the netted wooUy under surface of the leaves.) 



Shrubs ; herbage aromatic ; corolla regular. — Subgenus Neomacbridea. 

 Leaves glutinous, glabrous above or nearly so or at most pubescent. 

 Panicle or cvme open, branched. 



Leaves usually toothed, not revolute, mostly oblong. 



Calyx sparsely hirsute ; corolla thinly puberulent outside ; cent, and n. Cal

3. E. angustifoUum. 

 Panicle congested into a small head ; leaves very narrowly linear, entire, strongly revo- 

 lute; Purisima Hills, Santa Barbara Co 4. E. capitatum. 



Leaves white-tomentose (or usually so) on both surfaces. 



Corolla-throat open, the lobes gradually spreading; calyx densely white-hairy, not glan- 

 dular; capsule 2 lines long; intramontane and cismontane S. Cal 



5. E. crassifolium. 

 Corolla constricted or not expanded at throat, the lobes abruptly spreading ; calyx hairy 

 and glandular ; capsule 1 line long. 

 Calyx densely white-hairy throughout; coroUa 1% lines long; stems densely white- 

 tomentose; South Coast Eanges 6. E. tomentosum. 



Calyx dark-colored, thinly hairy on the upper half of the lobes, the lower half of the 

 lobes merely ciliate; corolla 3 to 4 lines long; stems thinly tomentose; 



coastal San Luis Obispo and Santa Barbara Cos. and Catalina Isl. 



7. E. iraskiae. 



Herb-like, the tall erect stems woody only at base; herbage hirsute, iU-scented; corolla slightly 



irregular; montane southward. — Subgenus TuESicui^ 8. E. parryi. 



1. E. californicum Greene. Yerba Sakta. California Mountain Balm. 

 (Fig. 408.) Shrub 2 to 8 feet high ; leaf -blades oblong to lanceolate, 21^ to 6 inches 

 long, Yz to 1 inch wide, dentate except at base or below the middle, very glutinous- 

 resinous on upper surface, as if varnished, the areas between the veins and cross- 

 veinlets on the under surface with a close dense felt ; petioles about Yo inch long; 

 panicle 3 to 10 inches long ; calyx 1 line long ; corolla white or lavender, tubular- 

 funnelform, 5 to 7 lines long; stamens unequal and unequally inserted above the 

 middle of the corolla-tube, these and the styles included; ovules 3 (or 2) to each 

 margin of a placenta ; capsule 2 to 8-seeded. 



Dry mountain slopes and ridges, 500 to 5500 feet, frequent and often abundant 

 and gregarious over extensive areas : Coast Ranges from San Benito and Monterey 

 Cos. to Del Norte Co. and western Siskiyou Co. ; Marysville Buttes; Sierra Nevada 

 from Kern Co. to eastern Siskiyou Co. North to southern Oregon. May-June. 



Biol. note. — Eriodictyon californicum, one of the more widespread and abundant shrubs in 

 California, is most commonly met with in the chaparral as an associate of Adenostoma faseicula- 

 tum, Ceanothus cuneatus, Ehus diversiloba, Garrya f remontii, Ehamnus crocea var. ilicifolia, Pick- 

 eringia montana, Arctostaphylos manzanita and A. viscida, Dendromecon rigidum and Quercns 

 durata. Occasionally it appears as pure colonies of several score or several hundred acres, espe- 

 cially on ridges where the clay soil, steepness of slope and certain drainage give it an advantage. 

 Such colonies may be observed on the south slope of Mt. Tamalpais, on Howell Mt., and on the 

 ridge westerly from Witter Sprs. in northwestern Lake Co. In many such cases it is the major or 

 exclusively successional species after repeated fire clearance of chaparral terrains.
