Mr. C. H. Thompson spoke of some plants the flowers of 

 which originate endogenously. He mentioned several species 

 of Rhipsalis in which the much reduced leaves grow on tri- 

 angular or cylindrical very succulent stems, their axillary 

 buds originating deep down in the soft tissue and sometimes 

 having a passageway extending toward the surface. In two 

 species of Rhipsalis (B, paradoxa and R. floccosa) there is 

 no such passageway, and the bud, in developing, breaks 

 through the epidermis. In Rhipsalis glaucosa, a number of 

 accessory abortive flowers were found. Cuscuta glomerata 

 was mentioned as the only other plant in which, so far as the 

 speaker knew, subepidermal flowers occur.
