COOK AND DOYLE—NEW GENERA OF PALMS FROM COLOMBIA. 235 
WETTINIA Poepp. & Endl. 
Wettinia Poepp. & Endl. Nov. Pl. Poepp, 2: 39. pls. 153, 154. 1838; * Wendl, 
Bonplandia 8: 104-106. 1860. 
Trunk solitary, 8 to 12 meters high, 15 to 20 cm. thick. 
Leaves with opposite simple pinn. ‘ 
Inflorescences simple, in verticillate clusters of 8 to 15, bearing flowers of 
one sex, but spathes of both sexes intermixed on the same trunk. 
Spathes five, three short and two much longer and complete. 
Male flowers with 4 or 5 minute sepals and 3 or 4 petals, valvyate in the bud; 
stamens 12 to 16; female flowers with 3 sepals and 3 petals; staminodes? ; 
ovary with 1 carpel and 1 ovule, obverse-pyramidate, villose; style filiform, 
rising at one side, from the base of the ovary; stigmas three, narrowly lanceo- 
late. 
Fruits obverse-pyramidate, flattened at the apex, strigose, hirsute, the endo-- 
carp delicately parcbment-like. 
Seed elliptical or obovate, surrounded with bundles rising from the base, run- 
ving together to the apex, then laxly anastomosing and coming together again 
at the embryo; albumen solid, uniform; embryo basal, erect. (PLATE 63, A.) 
Type species, Wettinia augusta Poepp. & Endl. loc. cit.; from the Huallaga 
Valley in eastern Peru.

WETTINELLA gen. nov. 
Trunk solitary, rather short (7 meters long), rather thick (12 to 20 cm.), 
becoming smaller above; smooth, distinctly ringed ; internodes long (20 em.). 
Leaves with long (168 cm.) scurfy sheathes; petiole short (15 em.) ; pinnse 
lanceolate, not inserted on a fleshy pulvinus; segments of unequal length but not 
divided; upper surface nearly smooth; lower surface densely brown hirsute, 
more pronouncedly so on the ribs; terminal pinne deeply divided. 
Inflorescences with 6 spathes, three small incomplete basal ones inserted close 
together and, well separated from these, three large complete ones, the latter 
inserted farther from each other; spadix compound, divided into several (about 
4) rather short, thick, fleshy branches which bear flow.1s of one sex deusely 
crowded together; surface of spadix below the flowers censely hirsute; fiowers 
moneecious, in different inflorescences, usually one female inflorescence and two 
to four male inflorescences at each node. 
Fruits cbovate, variously flattened and angled by mutual pressure, as bro.d 
as long or narrower, the surface rather coursely wrinkled cn the exposed end 
and densely beset with minute tubercles each bearing 2 long hair; style persist- 
ent, woody, inserted some distance (about 8 mum.) above the base of the fruit 
and bearing three linear, compressed, grooved stigmas equal in length to itself 
and scarcely exceeded by the apex of the ripe fruit; mature calyx and corolla 
also nearly as long as the fruit, the petals narrower and slightly longer than the 
sepals, the latter united at the base, the petals distiucl, mesocarp of rather fii 
corky texture, thicker at broadest part of fruit; inside cont of mesocarp a thin 
1The Index Kewensis credits this genus to Poeppig alone, with a reference to 
Endlicher’s Genera Plantarum (p. 243) with the date 1307. But Endlicher’s 
account of the genus contains no reference to a species that could serye aS a 
type.
