No. 8528, collected May 10, near vSinilh Creek, Santa Clara 

 county, elevation 2200 feet, on a wooded slope jrrowin}^ among 

 shrubs. The same thino; occurs on g-rassy hillsides about Los 

 Gatos and at other places in the Santa Cruz mountains. Doug- 

 las collected the type somewhere in this region. 



COLLINSIA BICOLOR Beutll. 



No. 8472, collected April 27, back of Alum Rock Park, 

 Santa Clara county, elevation 800 feet, on grassy banks near 

 trees. This is the typical form with large flowers, the upper 

 petals deep rose, the lower ones pale. The lobes of the upper 

 lip are oblong, either notched or entire, the throat open showing 

 a pronounced cavity. The dorsal side of the upper lip is raised 

 and spur-like at the base. The flowers are clustered on very 

 short pedicels. The type was obtained b}- Douglas, probably at 

 Monterey, where it is not uncommon. In the Synoptical Flora 

 Gray says the throat is "full as broad as long," which is by no 

 means the case, as it is 7 mm. long, barely over i mm. at base, 

 enlarged to between 3 and 4 mm. above, but is about 5 mm. deep. 



CoLLiNSiA FRANCISCANA Bioletti, Erythea 1: 17. 1893. 



No. 8463, collected April 25, on the western end of the San 

 Bruno hills, San Mateo county, elevation 500 feet, growing in 

 profusion in a tangle of other vegetation, especially on northerly 

 slopes. This might easily be mistaken for C. bicolor, as it re- 

 sembles it in habit and size of flower, but is distinguished by its 

 more scattered pediceled flow-ers, and in the living state by the 

 closed throat, the lower lip fitti'ng close against the base of the 

 upper one. While the dorsal .side of the upper lip is .slightly 

 curved, it is not raised and spur-like. Jepson considers this a 

 foim of C. sparsiflora^ On account of the pedicelled flowers, but 

 the two are quite distinct.
