PHACELIA FAMILY 201 



glandular, while our Yosemite variety, which has been 

 named and described only within the present year, is densely 

 glandular above, especially on the pedicels, etc. Its type 

 locality is at 5300 ft. alt. along the new Tenaya Trail, but it 

 also grows elsewhere around the Yosemite Valley in warm, 

 gravelly soil. 



P. vallicola Congdon, which grows at Hites Cove and El 

 Portal, is similar to no. 3 and with similarly small flowers but 

 these are nearly sessile and the leaves are broader (elliptic to 

 obovate). It also resembles P. purpusii, mentioned under no. 

 2, but the capsules bear many more seeds and the filaments 

 are perfectly smooth. 



4. P. menziesii Torr. Stems simple below, leafy, 3 to 12 

 in. high, pubescent. Leaves linear or lanceolate, entire or 

 some deeply lobed, 1 to 3 in. long. Pedicels very short, the 

 flower-clusters therefore dense. Corolla, bright violet or 

 white, more than % in. long, about equalling the stamens. 

 Calyx-lobes linear. Seeds 12 to 16 (or fewer by abortion). — 

 Yosemite Valley; common in northern California. 



5. P. magellanica Coville. Stems ^ to 2 ft. high, strictly 

 erect from a branching woody base, stiff-hairy. Leaves 

 mostly at base, rough-hairy, 1 to 6 in. long, lanceolate or 

 ovate, entire, or often lobed or the lower even with distinct 

 leaflets. Flowers in lateral and terminal coiled clusters. Cor- 

 olla whitish or pale blue, about Y^ in. long. Capsule 4-seeded. 

 (P. circinnata Jacq. f.) 



In this Phacelia we have one of the most common and at 

 the same time one of the most variable species that occurs 

 within our limits. It ranges from the foothills to regions 

 above timber-line. Many of the forms have been described 

 as distinct species, but these have been recently reduced to 

 forms by Dr. A. Brand, a German botanist. According to his 

 views, the genuine P. magellanica is restricted to South 

 America, while all of our forms come under the subspecies 

 barbata, and although they grade insensibly into each other 

 they may usually be segregated according to the following 

 synopsis, in which f. is the abbreviation for "form." Not all 

 of these have been found in the Yosemite National Park, 

 but they all occur in the Sierra Nevada and so are to be 

 expected. 



Plant very low, forming mats 1. f. compacta. 



Plant taller, not forming mats. 



Leaves all entire (with very few exceptions). 

 Stems low, 4 to 8 in. high; root perennial. 



Foliage silvery, shining 2. f. alpina.
