south of Camp 3, alt. 1400-1600 m; much branched tree 3-6 m, inflorescence branches reddish, 

 fruit green and 5-merous; 24 Dec 1953, Maguire, WurdacTc 4 Bunting 36862 (holotype, NY); 

 same place, Maguire, WurdacTc 4 Maguire 42583 (paratype). 



The vegetative similarity in canline formicaria and type of pubescence to the 

 two postulated relatives is remarkable; both these species, however, with their 

 subsessile-leafed relatives centering around C. data Pittier, have 4-merous flow- 

 ers. The inflorescence of C. neblmai appears terminal, but such other species of 

 Clidemia as C. coriaeta Xaud. also have terminal or pseudo-terminal inflorescences. 

 The present generic disposition of C. neblinae is based primarily on the notable 

 cauline formicarial specialization known to me in the family only in this Clidt mda 

 species-group.
