202 PHACELIA FAMILY 



Foliage gray with stiff hairs (an Alpine form)... 3. f. frigida. 

 Stems tall, mostly 1 or 2 ft. high; root often biennial. 4. f. griseophylla. 

 Leaves all or at least some of them deeply lobed. 

 Lower leaves with a single pair of lobes at base, or 

 some entire, the upper leaves mostly entire. 



Leaves 4-nerved 5. f. egena. 



Leaves 8-nerved 6. f. hetcrophylla. 



Lower leaves deeply parted into several or many 

 lobes. 

 Basal leaves long-petioled. 



Segments shortly acute 7. f. calif ornica. 



Segments long-acuminate; plant mostly white- 

 hairy 8. f . bernardina. 



Basal leaves short-petioled. 



Flower-cluster short, loose 9. f. patula. 



Flower-cluster long (1 ft. or more), dense 10. f. virgata. 



P. imbricata var. condensata Brand, has been accredited to 

 the Yosemite. It is like large forms of P. magellanica with 

 lower leaves lobed at base, but the calyces are much enlarged 

 in fruit and closely overlapping, the broadly ovate outer seg- 

 ment larger than the others, the margins all stiffly hairy. 



6. P. hydrophylloides Torr. Stems a foot or two long, 

 ascending from creeping woody rootstocks, short-hairy, leafy 

 to the top. Leaves silky-hairy, ovate, 1 or 2 in. long (exclu- 

 sive of the long petiole), cut-toothed or the lower deeply 

 lobed. Flowers in dense terminal clusters. Corolla violet or 

 whitish, y A in. long. Capsule 6 to 8-seeded. — Glacier Point, 

 Matterhorn Canon, and elsewhere, especially in fir forests. 



7. P. ramosissima Dougl. Stems spreading, 1 to 3 ft. high, 

 from a woody base, minutely pubescent, leafy. Leaves ob- 

 scurely hairy, \ l / 2 to 4 in. long, parted into 5 to 9 oblong 

 deeply toothed divisions or the upper simply lobed. Flowers 

 in dense coiled clusters. Corolla dull white, about J4 m - long. 

 Capsule 4-seeded. — Widely distributed but nowhere common: 

 Little Yosemite, Ledge Trail, Crane Flat, etc. Our form, 

 marked by its spreading or almost reclining habit, is tech- 

 nically distinguished as forma decumbens Brand (Phacelia de- 

 cumbens Greene). 



8. P. tanacetifolia Benth. Stems y 2 to 2 ft. high, erect, 

 from an annual taproot, sparsely stiff-hairy or glabrous, leafy 

 to the top. Leaves green, obscurely pubescent, finely dis- 

 sected into lobed divisions. Flowers in dense coiled clusters. 

 Corolla light blue or violet, }i in. long. Capsule 4-seeded. — 

 Foothills, also warm, sandy soil near Bridal Veil Falls. P. 

 distans Benth., is a related species with internal appendages 

 of corolla free at tip, instead of attached all the way up, as in 

 P. tanacetifolia. It may reach our lower borders.
