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 venusta Greene, according to Mr. Carl Purdy who 
discovered it, is a hybrid between Arevoortia /da-Maia and 
Brodiea congesta. 
Brodiea tnsularist Greene is 2. capitata Benth. 
 Triteleta candidat Greene is a not uncommon white form of 
Broditea laxa. 
Triteleia lugens § Greene is a form of Brodiva ixzoides with the 
appendages to the filaments shorter than usual. 
Triteleia lilacina\| Greene, known only in a single imperfect 
specimen collected by the writer, was not well described. It 
differs from typical Brodiza lactea only in the filaments above the 
membranous expansion adnate to the tube. In 7. /é/actna 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. grandiflora. 
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 intheirlength. Itseems 
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.
