filaments. In the Botany of California these are described as 

 filiform, which is probably never the case — they are thickened 

 toward the base and more or less deltoid-dilated in all the forms 

 found about the Bay of San Francisco. While it is possible that 

 one of Mr. Greene's species may be maintained it is much more 

 to be suspected that these forms, alike almost to the minutest 

 particular in all other respects, will prove to be filament 

 variations of the original. 



Bloomeria montana^ Greene is B. aurea Kell. 



Brevoortia vemista Greene, according to Mr. Carl Purdy who 

 discovered it, is a hybrid between Brevoortia Ida-Maia and 

 Brodi(za conge sta. 



Brodicea tnsularls\ Greene is B. capitata Benth. 



Triteleia candidaX Greene is a not uncommon white form of 

 Brodicea lax a. 



Triteleia lug ens %, Greene is a form of Brodicea ixioides with the 

 appendages to the filaments shorter than usual. 



Triteleia lilaci?ia\\ Greene, known only in a single imperfect 

 specimen collected by the writer, was not well described. It 

 differs from typical Brodicsa lactea only in the filaments above the 

 membranous expansion adnate to the tube. In T. lilacina the 

 membranous margin is nearly obsolete in the free part, while in 

 the ordinary form it is continued in triangular form nearly to the 

 top of the filament. Some specimens just received from Mrs. 

 M. E. P. McCowen, of Ukiah, are exactly intermediate between 

 typical lactea and lilacina. 



Hookera leptandra Greene, from the description; is a form of 

 B. grandifiora. 



Hookera rosea ^ & Orcuttii ^ Greene as well as several species 

 by other recent authors, will certainly be found untenable. They 

 are all founded on the presence or absence of staminodia, appen- 

 dages to the filament, or slight variations in their length. It seems 

 even to be the opinion of some that the shape of the staminodia, 

 more or less notched as they approach the anther form, entire 

 or acuminate as they recede, is sufficient warrant for the separation 

 of species.
