17. A. serratum Wats. Scape 8 to 15 inches high; bulb-coats horizontally 

 serrate-reticulate, the reticulation close but distinct ; bracts narrowly acuminate ; 

 perianth-segments pink, broadly ovate-lanceolate, 4 to 6 lines long, acute or some- 

 what acuminate, nearly straight and rather rigid, the inner narrower, somewhat 

 shorter and rarely serrulate ; filaments all with a narrowly deltoid base ; ovary 

 crests very minute, narrow, central, 2-lobed. 



Lower hills of the inner Coast Range from Solano Co. to the Mt. Hamilton 

 Range, thence west to the inner slopes of the Santa Cruz Mts., 300 to 2000 feet. 



As here restricted a satisfactory and somewhat localized unit. This species has hitherto 

 been made to do duty over too wide a range. Its umbels have more numerous flowers and its 

 perianth is thinner than in A. peninsulare. After anthesis the tips of the perianth-segments 

 are bent in abruptly and connivent at the center, the whole perianth becoming bladdery inflated.

 Douglas; Jepson, Fl. W. Mid. Cal. 120 (1901). 



18. A. dichlamydeum Greene. Lower than A. peninsulare but very similar; 

 umbels very compact, the pedicels 14 to % inch long ; perianth-segments spread- 

 ing almost equally, the outer narrowly to broadly elliptic, rounded or as if trun- 

 cate but shortly acute, the inner for the most part nearly as broad. 



Maritime, in a coastal belt from San Mateo Co. to Mendocino Co., extending 

 inland only to the coast-like "island" of vegetation in ne. Contra Costa Co. 

 Bracts 2, commonly united below into a cup ; in A. peninsulare they are less 

 united or distinct.

19. A. peninsulare Lemmon. (Fig. 47e.) Habit and bulb-coats of A. ser- 

 ratum, the scapes usually more stocky ; pedicels % to 1*4 inches long ; perianth- 

 segments deep red-purple, 5 to 7 lines long, the outer 3 broadly ovate-lanceolate, 

 somewhat spreading, twice the breadth and usually 14 longer than the 3 inner 

 erect attenuate segments which form a sort of inner cup ; filaments i/> to % the 

 length of the segments, those opposite the inner segments with deltoid bases 

 longer than the bases of those alternate : ovary crests central, very minute, nar- 

 rowly 2-lobed.
