8 Contributions from the Gray Herbarium 
which M. coronata, as Mrs. Brandegee has suggested, Zoe, iv. 101, 
should be merged) has the unarticulated pedicels of M. maritima. 
Although the presence of the jointed pedicel might serve as a 
means of distinguishing generically Muilla and Bloomeria it would 
result in arbitrarily keeping in separate genera plants which are 
quite similar in all respects which possess any degree of taxonomic 
moment. For instance Bloomeria Clevelandii with its pale flowers 
and several leaves simulates closely in habit Muilla maritima and 
although in this particular example a distinct difference in the 
structure of the corolla could be shown this difference is not so 
great nor so well marked as is the case in certain groups of Brodiaea 
some of which, furthermore, have jointless, others jointed pedicels, 
but which, nevertheless, every conservative botanist retains under 
the one generic name. But it so happens that recently a plant 
has been collected in Mexico which has the narrow filaments of 
true Muilla but the pedicels jointed like those of Bloomeria! This 
fact is not mentioned by Brandegee who described the plant as 
Mulla Purpusii, Univ. Cal. Publ. Bot. iv. 177 (1911). The blue- 
green flowers and the general aspect suggest at once a relationship 
to M. maritima. When therefore all the known species of Muilla 
and Bloomeria are considered it becomes apparent that they belong 
to one genus which must be known as Bloomeria, since it is the 
earlier name.

This montane form of southern California differs from the typical 
state of the species chiefly in the more robust habit and more nU- 
merous flowers. These are differences which are in no way funda- 
mental, however, so this southern plant may best be treated as 4 
geographical variant. Moreover the typical form has been secu 
recently by Abrams in Orange and Kern counties, which collections 
indicate a period of flowering that corresponds with that of the 
variety. Brandegee’s no. 3382 from San Diego, referred by 
Eastwood to M. serotina, is an intermediate state.
