ALLIACEAE Batsch, Gan. PI. Jenens. 10, 30. 1786. 

 Allium dichlamydeum Greene 



No. 8564, collected May 23, about two miles beyond San 

 Mateo, San Mateo county, on the Half Moon Bay road, growing- 

 on a steep bank near and among trees in rich loose soil, the 

 slope facing the west. This is probably the southern limit of 

 the species, and it is more sheltered here than at its native hab- 

 itat on the open hills about San Framcisco. 



Allium Breweri Wats. Proc. Am. Acad. 14:' 233. 1879. 



No. 8618, collected May 31, near the summit' of Mt. Ham- 

 ilton, Santa Clara county, at an elevation of 4000 feet; where it 

 is plentiful on a northerly slope, growing on and about loose 

 shingly rocks. The type was collected by Brewer on the sum- 

 mit of Mt. Diablo, and the plant has apparently not been re- 

 ported from elsewhere until now. 



Allium lacunosum Wats. Proc. Am. Acad. 14: 231. 1879. 



No. 8699, collected May 31, on the slopes of Mt. Hamilton, 

 Santa Clara county, above Smith Creek, in open grassy places 

 near oak trees. It was found sparingly at this place, but occurs 

 along the Mt. Hamilton road near Hall's valley. The type was 

 collected in "Santa Clara County, on Mariposa Peak." The 

 elevation at our station isabout\27oo feet. 



DiCHELOSTEMMA CAPITATUM (Benth.) Wood 



No. 8569, collected May 24. on the hills west of Los Gatos, 

 Santa Clara county, elevation about 800 feet. It is common in 

 our own and neighboring orchards, usually about two feet high, 

 and as a rule growing in colonies. I have never seen it show- 

 ing a tendency to twine or lean upon other plants for support. 

 The appendages of the anthers in this species are white, lanceo- 

 late, entire.
