since it was incompletely described by Weddell (in Ann. 
Sci. Nat. III. 10 (1848) 9) from fruiting material col- 
lected by him in the Province of Carabaya (Dept. of 
Puno). While collecting in the same area during 1948, 
I discovered Cinchona carabayensis, but unfortunately 
my specimens of this species were among a number lost 
in transit in Peru. I still have very sketchy field notes 
and these may be of some value in relocating the species. 
In the ‘‘Flora of Peru’’ Standley states that C. cara- 
bayensis was described ‘‘from thickets on the summits 
of the mountains between the valleys of the Province 
of Carabaya, especially near San Juan del Oro.’’ Pre- 
sumably these data came from the type label, for Wed- 
dell, in his original descriptions, merely gives the locality 
as ‘‘Peruvia.’” San Juan del Oro, now long abandoned 
and consequently not found on modern maps, was the 
most famous of the Spanish placer mining centers in 
this auriferous zone of southern Peru and was located 
on the ridges separating the watersheds of the Upper 
Inambari (here called the Huari-Huari) and Upper Tam- 
bopata Rivers. The much overgrown site of the mine 
may be reached by trail in about two days from the town 
of Sandia. Since Weddell’s time the Province of Cara- 
baya has been divided, with the result that old San Juan 
del Oro, as well as most other important cinchona areas 
(such as the Tambopata Valley, ‘‘Valle Grande’’ of the 
Huari-Huari, ete.) inthe Department of Puno, are now 
included in the modern Province of Sandia. On the 
other hand, the modern Province of Carabaya, with Mac- 
usani as the capital, occupies only that part of the old 
Province of Carabaya lying west of a line drawn north 
and south through Limbani, a line which roughly paral- 
lels the Limbani-Mina Sto. Domingo-Astillero mule 
trail. 
It was in this same general area in early 1948 that C.
