PLANTS COLLECTED IN ECUADOR BY W. H„ CAMP 

 VACCINIACEAE 



A. C. Smith 



In 1944 and 1945, Dr. W. PL Camp made very extensive collections of plants 

 in Ecuador, among which were included approximately 300 numbers of the family 

 Vacciniaceae. Because of his special studies of this family, Dr. Camp's material 

 and field-notes are of the greatest interest and value. At his request the writer 

 has undertaken the identification of these specimens and has described those 

 that appear to represent new species. That there are 29 such species described 

 in this paper reflects on the industry and perspicacity of Dr. Camp and his as- 

 sistants, F„ Prieto and H. Jorgensen, as well as upon the little-known nature of 

 the flora of Ecuador. In this country and in Colombia the Vacciniaceae reach 

 their highest development in America, both as to number of species and diversity. 



The first set of the material upon which this paper is based is deposited in 

 the herbarium of the New York Botanical Garden, and a second set in that of the 

 U. S. National Museum. All the specimens of the family collected are cited and 

 are represented in both herbaria unless followed by the annotation "NY only." 

 A few other specimens are mentioned, the place of deposit being shown by the 

 standard symbols: A (Arnold Arboretum); Ch (Chicago Natural History Museum); 

 NY (New York Botanical Garden); US (U. S. National Herbarium )„ Genera are dis- 

 cussed in the sequence proposed by H. Sleumer's "Vaccinioideen-Studien" (Bot. 

 Jahrb. 71: 375-408. 1941). 



Gaylussacia loxensis Sleumer, Bot. Jahrb. 71: 384. 1941. 



Azuay: "Oriente" Border, east slope of Eastern Cordillera, between Ona and 

 the Rio Yacuambi, 8,000-9,500 ft. dev., F. Prieto P-265 (NY only) (shrub 1 m.; 

 corolla bright pink). 



This unicate collection agrees very well with the original description of G. 

 loxensis, but I have not compared it directly with type material (Lebmann 4965 

 pro parte). As compared with the description, our specimen differs only in its 

 somewhat more pilose flowers and slightly longer corolla (to 9 mm. long at anthesis).
