VENEZUELA: Bolivar: Kio Suapure, locally abundant at east base of Cerro Pijiguao 

 (north end of Serrania Suapure about 70 river km from mouth), alt. 110 m; herb 2 m; 

 flowers pale yellow; 19 Jan 1956, J. J. Wurdack 4 J. V. Monachino 41287 (type, US). Entre 

 roeas en las riberas de un arroyo en la selva del Salte de Para, alt. 300 m ; arbusto delgado, 

 hasta de 3 m de alto; fis. amarillas; 3 May 1939, Llewelyn Williams 11383 (paratype, US). 

 Amazonas: Cerro Guanay, Cano Verada, occasional in deciduous woodland between Campo 

 Verada and Campo M. Perez, alt. 900-1100 m; subshrub ; branches herbaceous; flowers pale 

 yellow; 30 Jan 1951, Bassett Maguire, Kathleen D. PJtelps, Charles B. Hitchcock 4' Gerald 

 Budowsky 31667 (fruiting specimen; paratype, US). 



The flowers and bracts on falling leave conspicuous raised scars (up to about 

 20) crowded on a more or less conelike rachis, this 1-4 cm long. Although not 

 very closely related, the species reminds one of R. bourgaei Hemsl. of Mexico. 

 The specific epithet is from the Greek word jiaXaxos, meaning soft (Latin mollis) 

 in allusion to the velvety puberulence.
