COOK AND DOYLE—NEW GENERA OF PALMS FROM COLOMBIA. 231 
Catostigma radiatum sp. nov. Priates 56 (B), facing p. 230, 59 (A), 60. 
Trunk 6 meters long, 5 meters to first inflorescence, the diameter 7 to 8 cm. at 
1 meter from base, 6.5 cm. at base of first leaf; wood very hard and fibrous. 
Leaves 10 to 12 in a head, largest in the middle, tapering gradually toward 
base and tip; leaf bases 108 cm. long, splitting into numerous. fragile fibers: 
lower surface densely brown tomentose for about one-half its length; petiole 
34 em, long by 2.5 cm. in diameter, cylindrical ; surface densely tomentose m 
young leaves, smooth in adult specimens; rachis 272 cm. long by 2.5 em. thick 
at base, tapering gradually toward the tip; lower surface rounded, becoming 
flat; upper surface for 50 cm. outward from base with a prominent, rounded, 
central ridge becoming more prominent; upper surface also marked with minute 
grooves; toward the tip the latter disappearing and becoming flat surfaces, the 
central ridge becoming more prominent; upper surface also marked with minute 
longitudinal raised lines running the entire length of the leaf, less prominent 
toward the tip. 
Pinne 57 to 62 on each side, simple or split into 2 to 7 divisions and consist- 
ing of from 1 to 10 segments ranging in width from 1 to 3 cm., the divisions 
standing at different angles to the rachis; tips of pinnze notched, due to unequal 
termination of segments, the lower segments generally the longest; upper sur- 
face of pinne dark green, the lower surface lighter; at the point of insertion 
of each pinna a fleshy cushion or pulvinus; just below the insertion of each 
pinna the rachis naked and lighter in color for 2 cm. or less; for 2 to 3 cm. 
below the insertion of each group of pinne the lower surface elad with a 
dense tomentum easily removed with the fingers; lowest pinns 29 em. long by 
6 to 7 em. wide, consisting of 6 segments 1 cm. or less in width; lower and 
terminal pinne inserted singly: middle pinnz 33 to 56 cm. long by 4.5 to 138 cm. 
wide, consisting of 2 to 9 segments 2 cm, or less in width; terminal pinne 17 cm. 
long by 7 to 9 em. wide, consisting of 8 or 9 segments 2 cm, or less in width. 
Inflorescences infrafoliar, as many as five maturing fruit at one time; total 
length 105 cm.; peduncle to first branch 30 cm. long by 2.5 cm. in diameter at 
base and 2 em. at first branch; fruiting portion 4 cm. long by 1.5 em. in 
diameter; both peduncle and fruiting portion light green, smooth; branches 3 
or 4, 71 em. or less in length by 2 em. in diameter. 
Spathes 5, the lowest 4 cm. long by 4 cm. in width at base; inner spathe 26 
em. long, smooth; usually three inflorescences, two male and one female, ap- 
pearing in a group at the same node. 
Fruits densely clustered along the branches, oval 3.5 cm. long, 1.8 cm. in 
diameter; outer husk corky, brittle, 2 to 3 mm. thick; seed broadest below the 
middle, covered with a closely adherent, fibrous, fragile epidermis; texture 
bony; embryo basal.

collected along bank of stream near Cordoba, Cauca, Colombia, by C. B. Doyle, 
December, 1905.
