 cessubus papiliosis extus vestitae. Adsunt aliquando lacinulae lineari-lanceolatae ad latus

 inflexuram et coalitionem laciniarum sepalorumve cum columna), circa basin partis

Obs. I. — The axis of this plant consists chiefly of roundish cellular tissue, 

 towards the middle of which there is a simple series of vascular fascicles ; the 

 transverse section of these is cuneate or subovate, the narrow end, and this is 



* Mr. Harvey tells me he has always found this plant on the above Syngenesious species, which 

 does not appear to sutFer from being preyed upon. The same innocuousness has, I believe, been re- 

 marked of C. Hypocistis.
