of L. glahratus separate from one another is a little uncertain : the flowers described 

 above were young ones soaked and expanded in boiling water ; and it is i)ossible that 

 the corolla in a living state splits unilaterally and that the lobes cohere slightly in a 

 single piece up to the insertion of the stamens, as in i. Fischeri. 



Following Engler in Engl. JaJirh. xx. 81, 107, I have kept up the two suctions 

 Longicahiculati and Co7'iaceifolii, ti'ansferring to the latter, however, all species in 

 which I have found a tooth at the apex of the filament, in strict accordance with 

 Engler's scheme of classification. That too much reliance has been placed on the 

 presence or absence of a tooth on the filament is evident, however, from the close rela- 

 tionship between L. glahratus, which has a tooth, and L. Fischeri, which has none. 



It would probably be a more natui-al arrangement to make the presence of 

 appendages within the corolla-tube the criterion of the Coriaceifolii.
