ELATERIOPSIS. 



In 1872 Doctor Ernst discovered in Venezuela a new cucurbitaceous 

 plant, which he placed between Ekterium and Hanburya under the 

 name of Elateriopsis caracasana. a In this genus, the stamens are 5 

 (or sometimes 4), 4 of them being connate in two pairs, thus reducing 

 the apparent number to 3; the stigmas are distinctly 3-lobate and 

 the seeds rather large and flattened with a thin, sinuate margin. 

 These characters are in themselves sufficient to segregate Elateriopsis 

 as a generic unit, so that, notwithstanding his rather conservative 

 tendencies, Mr. Cogniaux felt first inclined, in 1877, b to uphold it, 

 and even increased it by one species (E. macrojwda) , transferred from 

 Momordica. But in 1881, the same author receded from the former 

 position and amalgamated Elateriopsis with Cyclanthera as a mere 



a See Flora 56: 257. 1873. & Diag. Cucurb. 2: 82. 1877.
