Compared with Jameson's specimens from Pichincha and 

 Pearce's from the Andes, duplicates of which have been sent to us 

 from Kew. The specimens collected by Miguel Bang (No. 482) 

 at Yungas, and listed by^r. Rusby (Mem. Torr. Club, 2 : No. 3, 

 p. 274) as TInixidiuvi delicatuluni, were so named by Mr. C. H. 

 Wright at Kew. Duplicates of all our specimens, including these, 

 were submitted to Dr. George N. Best for critical comparison. 

 He says : " They apparently belong to one and the same species. 

 The stem leaves differ from those of T. delicatnhmi in not being 

 closely appressed when dry ; they are more concave, broader at 

 base and more abruptly acuminate, somewhat undulate and ru- 

 gose above, and the leaf-cells are more rectangular and less rhom- 

 boidal. Notwithstanding these differences, which indicate a vari- 

 ety rather than a distinct species, the general type remains well 

 marked. I should refer your specimens to T.delicatuluin." But as 

 these specimens are much larger and coarser than any of 7. deli- 

 catulutn which we have ever seen, and they seem worthy of a 

 distinctive name, we have maintained them as above listed.
