Puerto Ospina y Concepcion, alt. 250 m. Nombre vulgar: cacao sil- 
vestre, cacao de monte. ‘‘Small tree, 12 ft. tall. Flowers dark red. 
Kofan name: ko-kee-ot-chu.’’ April 20-30, 1942, R. E. Schultes 3670. 
Herrania Mariae (Mart.) Decaisne ex Goudot var. 
putumayonis PF. FE. Schultes var. nov. 
Arbuscula usque ad duodecim vel quattuordecim 
pedes alta, ab Herrania Mariae principaliter foliolis mul- 
to majoribus (usque ad 52 cm. longis, 18 cm. latis), 
lanceolato-ellipticis (non conspicue rhomboideis); peti- 
olis robustioribus et longioribus; floribus majoribus, ala- 
bastro globoso usque ad 17 mm. in diametro; ligulis 
brevioribus, usque ad 70 mm. longis sed saepissime paulo 
brevioribus differt. 
Additional material may indicate that this concept is 
deserving of specific rank. At the present time, however, 
it would seem advisable to treat it as representing a va- 
riety of Herrania Mariae. The fruit of Schultes 4010 is 
hardly distinguishable from that of Herrania Mariae. 
The flowers have several differentiating characters, the 
most conspicuous of which is the shorter ligule. Vege- 
tatively, the collection is extremely similar to Herrania 
nycterodendron (with the type plant of which it was 
growing) and differs markedly from H. Mariae chiefly 
in the departure from the typical rhomboid form of the 
leaflets and in their unusually large size. The type plant 
of Herrania Mariae var. putumayonis consisted of four 
or five trunks ina clump, whereas H. Mariae usually, if 
not always, is a treelet with a single trunk. 
Herrania Mariae var. putwmayonis may represent a 
western variant of the species which is most abundant 
in the eastern half of the Amazon basin.
