Flevea andenensis C.F. Jones “South American” 
(1940) 222. 
In his book “*South America,” Clarence F. Jones has 
published what would appear to be a nomen nudum — 
Hevea andenensis — in av passing reference to the source 
of Peruvian rubber. Although this publication can in no 
way be considered as a natural history and although no 
specimens were cited, the binomial may be picked up by 
some of the many non-technical writers who are present- 
ing works on various studies in Latin American affiurs. 
In order to preclude any confusion which might result 
from the perpetuation of the nomen nudum, the present 
note appears to be advisable, 
We are not certain, of course, as to the exact concept 
which Jones had in mind when he used the binomial. 
Jones speaks of the plant as growing at a digh altitude. 
Seibert (in Ann. Mo. Bot. Gard. 84 (1947) 298) states 
that ‘Hevea gmianensis in pure strain appears to have 
been collected rarely in Pert” but (le. 2904) that AZ. 
eguianensis Var. lutea “is a characteristic tree of the Peru- 
vian montana” and “is found on much of the Peruvian 
tierra altura {sic} and hilly land of the Peruvian Amazon 
basin... on the eastern Andean foothills, occasionally 
as high as 5000 feet.”” In view of this, I believe that we 
are justified in referring Hevea andenensis to HM. guianen- 
sis var. luted. 
It is possible that Jones’ binomial is an incorrect 
rendering of another nomen nudum— Hevea andinensis 
Sperber (in ‘Tropenfl. 14 (1910) 96)—but there is no evi- 
dence that this is the case.
