COOK AND DOYLE—NEW GENERA OF PALMS FROM COLOMBIA. 237 
Inflorescences infrafoliar, five from one node, one or two female, the rest 
male; total length of female inflorescence 75 cm.; peduncle 36 cm. long by 8 
cm. in diameter at base, abruptly narrowing to 2 cm., then widening again to 4 
em. at base of first branch, densely covered with light brownish tomentum, 
this more pronounced toward the base; branches 4, 39 cm. or less in length, 7 
cm. in diameter at point of insertion, abruptly narrowing just above. 
Fruit densely crowded along the branches, quadrangular top-shaped by 
mutual pressure, 2.5 em. long by 2 to 2.5 cm. in diameter at widest point; 
densely gray-tomentose; outer shell corky, 1 to 3 mm. thick; seed oval, 
broadest above the middle; embryo basal. 
Type in the U. 8. National Herbarium, nos. 690424, 690425, 690433 (all from 
one tree), collected in deep damp forests about Cordoba, Cauca, Colombia, 
about 10 miles inland from Buenaventura, by C. B. Doyle, in December, 1905. 
Native name, “ gualte.”

This palm was described by Spruce as a second species of Wettinia, the 
differential characters being stated as follows: 
“ Wettinia maynensis differs from W. augusta chiefly in the more numerous 
pinne (38-40 pairs, while in W. augusta they are but 18-20 pairs), and in the 
spadices, which are only three from one leaf-ring, and put forth 5-8 fastigiate 
branches at their apex; while in W. augusta they are simple, and as many as 
from 8 to 15 grow from the same ring. There is a further difference, in the 
spathes, which in W. maynensis are 6 in number, the three outer (corresponding 
to what are called by Martius in other genera ‘spathae incompletae’) much 
smaller, and persisting on the peduncle in the form of sheaths; while the three 
inner and larger ones (‘spathae completae’) fall away before the fruit is 
ripe, or persist only in fragments. In W. augusta the spathes are said to be 
two, and the peduncle is said to be furnished with remote coriaceous sheaths— 
undoubtedly the remains of the incomplete spathes. In both specimens the 
sepals vary in number, and the stamens are from 12 to 16, nor does there seem 
to be much difference in the form of the fruit; but in W. maynensis the arilli- 
form raphe is in every stage thin and papery, while in W. augusta it is fleshy. 
In Endlicher’s description, the scale-like external sepals are considered bracts; 
but as they quite correspond to what are called sepals in other palms, I de- 
seribe them as such.” ? 
It would seem that Spruce’s palm is more closely allied to our Wettinella 
quinaria, which has a branched spadix, and it is therefore placed as a second 
species of this new genus. Its chief characters which separate it from quin- 
aria lie in the fewer inflorescences from each node, 3 instead of 5, and in the 
much shorter sepals and petals. Spruce says that in W. maynensis the female 
spadix is very constantly 5-branched, while in W. quinaria there are only 4 
branches. The following additional details are given by Spruce, mostly in the 
form of a long Latin description:
