300 feet, growing in moist places along the roadside, the expos- 

 ure northerly. At this time the flowers had nearly all fallen, 

 the few remaining ones somewhat smaller than the early spring 

 ones. This is the most southerly station recorded, the type from 

 near San Francisco. 



COLLINSIA SPARSIFLORA lud. Sem. Hort. Petrop. 2: 33. 1835. 

 No. 8539, collected May 9, on the grade leading into Hall's 

 valley, Santa Clara county, elevation 1750 feet, growing along 

 the roadside on grassy northerly slopes. The flowers are very 

 small, not over 3 or 4 mm. in length, but in similar situations 

 near Smith Creek some plants were found with flowers almost 

 again as large, the two forms growing together. In the original 

 the flower is described as intermediate between that of C. gran- 

 diflora and C. parvifioi^a. The type locality is Fort Ross, So- 

 noma county. 



MiMULUS ARVENSis Greene, Pittonia 1: 37. 1887. 



No. 8517, collected May 10, near the summit of the grade 

 leading from Smith Creek into HalPs valley, Santa Clara county, 

 elevation 2250 feet, in wet places along the roadside. The stems 

 are rather robust, though only about 15 inches high, but it has 

 the white-villous floral leaves of the typical plant. No type lo- 

 cality is specified, but specimens are cited from Lake, San Ma- 

 teo and Marin counties. I have it from Sonoma county and 

 from the Santa Cruz mountains back of Los Gatos.

No. 8591, collected May 30, near Smith Creek, Santa Clara 

 county, elevation 2150 feet, in damp places in a ravine near 

 shrubs. The plants were mostly of large size and upright habit 

 as is usually the case when growing in the open. A weak and 

 spreading form is found under overhanging rocks or in places 

 much shaded. It has quadrangular stems. The type came 

 from Knight's valley, Sonoma county.
