200 PHACELIA FAMILY 



A. Stamens scarcely if at all exceeding- the corolla; low annuals. 

 Seeds 4 or fewer in each capsule. 



Leaves mostly near summit, opposite 1. P. racemosa. 



Leaves basal and scattered, some alternate 2. P.humilis. 



Seeds 8 to 20 in each capsule. 



Flowers not % in. long; pedicels evident 3. P. curvipes. 



Flowers over K in. long; pedicels very short 4. P. menziesii. 



B. Stamens much longer than the corolla. 



Leaves gray-hairy, the upper ones entire or merely 

 toothed. 



Stems sparsely leafy; ovules 4 5. P. magellanica. 



Stems leafy to the top; ovules 6 to 12 6. P. hydrophylloides. 



Stems leafy; ovules 12 to 16; leaves mostly entire. 4. P. menziesii. 

 I eaves bright green, all deeply lobed. 



Perennial, with spreading stems 7. P. ramosissima. 



Annual, with erect stem 8. P. tanacetifolia. 



1. P. racemdsa Brandegee. A delicate erect annual, nearly- 

 naked up to the branching flower-cluster, 2 to 9 in. high, 

 glandular-pubescent only above. Leaves linear-lanceolate, 

 entire, ^ to 2 in. long. Flowers blue, % in. long, pedicels 

 shorter than calyx. Seeds 4. (P. namatoides Gray.) — A rare 

 species, found at Glacier Point. 



2. P. humilis T. & G. Stems simple or branched, leafy, 

 3 to 9 in. high, whole plant with short spreading hairs. Leaves 

 alternate (lower rarely opposite), narrowly lanceolate, entire, 

 V/2 in. or less long. Pedicels all shorter than calyx, the 

 latter with linear lobes. Corolla indigo-blue, scarcely J4 in- 

 long, the stamens a little longer. Seeds only 4 in each cap- 

 sule. — Yosemite Valley (summit of El Capitan, Nevada 

 Falls), Alder Cr., Stubblefield Canon, etc.; probably through- 

 out our district. 



P. eisenii Brandegee, may occur. It is like P. humilis, but 

 with slender pedicels longer than the calyx and 2 distinct 

 styles. P. purpusii Brandegee, is also similar, but known by- 

 its broad, almost obovate calyx-lobes. It grows in the foot- 

 hills, perhaps reaching Yosemite Valley. 



3. P. curvipes var. yosemitana Brand. Stems simple or 

 commonly much branched, 3 to 12 in. high, rough-pubescent, 

 usually purplish. Leaves oval or oblanceolate, entire, the 

 blade J4 to 1 in. long, often equalled by the slender petiole. 

 Lower pedicels as long as calyx. Corolla violet or blue, under 

 *4 in. long, the stamens usually shorter. Seeds about 16 to 

 20, 3-angled, the capsule shorter than the enlarged spatulate 

 calyx-lobes. 



This Phacelia has doubtless come to us from the south, 

 since the species is common in the drier parts of the southern 

 Sierra Nevada. These southern plants are scarcely if at all
