precise locality of Camp's no. 2 734, indicating the possibility that the two species 

 hybridize in this region, if, indeed, 5". sodiroi is more than a very extreme form 

 of S. corck folium. 



Sphyrospermum sp. 



Santiago-Zamora: Valley of the Rio Zamora, east of Loja, near Zamora, about 

 3,000 ft. elev., Camp E-16 (epiphyte, over river; fruit pale blue). 



This fruiting specimen represents a species not otherwise in Dr. Camp's mate- 

 rial. In the texture and general shape of its leaves it suggests the Peruvian S. 

 weberbaueri (Hoer.) A. C. Smith, but it differs in the leaf-blades with rounded- 

 obtuse apices and in the short-pedicellate fruits. I think it probable that the 

 specimen represents an unde scribed species. 



Eleutherostemon Herzog. 



A note on this little genus and a discussion of the eight species now known to 

 compose it have recently been published by the writer (Contr. U. S. Nat. Herb. 

 29: 350-355. 1950). Collections of Eleutherostemon are still rare, and conse- 

 quently the eight numbers of it obtained by Dr. Camp are very welcome. The only 

 previous records of the genus in Ecuador refer to E, amplectens (Sleumer) A. C. 

 Smith and E. octandrum (Sleumer) A. C. Smith (as Diogenesia octandra Sleumer, 

 Bot. Jahrb. 71: 396. 1941), and it is possible that the latter record is referable to 

 one of the species I describe below as new. Eleutherostemon amplectens is not 

 among Dr. Camp's collections, all of which, in my opinion, represent undescribed 

 species.
