as in the case of Crocus nudiflorus mentioned 03^ Masters, 2 and quite 

 often the rule in cases of pistillody of the stamens. 



The occurrence of floral and vegetative abnormalities in both 

 Eastern and Western species of the genus Trillium is frequently 

 mentioned in the literature on the subject. The most complete de- 

 scription and illustration of such abnormalities is that of Britcher, 3 

 in the case of the Eastern T. grandiflorum*, which the Californian 

 T. ovatum, with its pedunculate flowers, resembles. Appended is a 

 partial list of references to the literature dealing with teratology 

 in *the genus Trillium which may be of interest, as indicating the 

 range of its possible floral and vegetative abnormalities. 



This brief note on pistillody in Trillium sessile, var. giganteum, 

 is presented both for the sake of putting upon record this somewhat 

 unusual floral abnormality, and also in the hope that it may call the 

 attention of the members of the California Botanical Society to 

 what may be a new, and to what cannot fail to be an interesting, ob- 

 jective on their botanical expeditions. There is distinct scientific 

 value in a thorough knowledge and catalogue of cases of teratology 

 exhibited by the California flora, and such knowledge must be accu- 

 mulated concurrently with the extension of systematic studies 

 throughout the native flora. The California Botanical Society might 

 entertain the suggestion that a secondary aim of their expeditions 

 be the collection of all significant floral and vegetative abnormalities 

 for the herbarium, while this journal might establish a section de- 

 voted to the recording of the most interesting cases of teratology.
