BRAZIL: Amazonas: high central forest, Igarape Jandistuba, S. Paolo de Olivenca, 

 Rio Solimoes; 2 Feb 1949, B. L. Froes 24060 9 (holotype, NY). 



Unfortunately, Quapoya froesii is represented by but a single pistillate 

 collection of which the flowers are immature. The bracts and sepals most 

 nearly resemble those of the Guiana Q. bracteolata Sandw. ; and next to those 

 of Q. peruviana (P. & E.) O. Kuntze. 



The collector describes the plant obtained by him in the field asa " strangler 

 on top [of] very high trees, [with] white rosy fragrant flowers." 



4. Quapoya bracteolata Sandwith, Kew Bull. 1931: 177. 1931. 



Bengifa acuminata Planchon & Triana, Ann. Sci. Nat. ser. 4. Bot. 16: 243. 1860. 

 Quapoya acuminata Kuntze, Rev. Gen. 61. 1891; not Q. acuminata Walp. Repert. 1: 393. 



1842. (=Clusia acuminata Sprengel, Syst. Veg. 2: 599. 1825). 

 Benggeria montana Klotzsch in Schomb. Reisen 3: 1093. 1848; nomen. 



Type: ''Roraima, Brit, Guiana, 1842-3," Schomburgk 999 (holotype, P; 

 isotypes, G, K, NY, W). 



So far as collected, Q. bracteolata occurs only in low-altitude rain-forests of 

 British Guiana. The notation "Roraima" on the original Schomburgk label 

 must be held suspect. 



Although characteristically numerous decussate bracteoles subtend the 

 flowers, principally the staminate flowers, some specimens, notably Jenman
