PITTIER—-PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 489 
In the National Herbarium there is one specimen, with male flower, 
of another Calycophysum collected in Santa Marta, Colombia, by 
Herbert H. Smith (no. 1603). This is labeled C. pedunculatum, but 
it so far disagrees with the description of that species, as well as 
with that of @. gracile and with my own plant, that there is little 
doubt that it represents a new species. It is here described as (. 
cordatum. 
We may, then, recognize at the present time at least five species of 
Calycophysum which may be distinguished by the following key: 
Leaves cordate: filaments 2 em. long__--_-_.-_----------- C. cordatum Pittier. 
Leaves subtrilobate; filaments much shorter. 
Calyx not over 3 em. long, the segments narrow. Filaments 5 to 7 mm. 
long___--_------_------------------------------------- C. gracile Cogn, 
Calyx more than 3 cm. long. 
Segments of the calyx broad and somewhat rounded. 
C. pedunculatum Triana, 
Segments of the calyx narrow and acuminate. 
Petioles and peduncles tomentose-pubescent_--------- C. brevipes Pittier. 
Petioles and peduncles villous-tomentose with long hairs. 
C villosum (Cogn.) Pittier. 
Calycophysum cordatum Pittier, sp. nov. 
A vine, the stems glabrous or glabrescent. Leaves membranous, the petioles 
terete, 4 em. long, minutely toméntose-pubescent, the blades cordate, short- 
acuminate, 8 to 10 em. long, 9 to 11 cm. broad, remotely subulate-denticulate, 
light green and sparsely pubescent above, densely pubescent beneath, the basal 
sinus about 2 em. deep and 1 cm. broad, subrectangular. 
Staminate flowers solitary in the axils of the leaves; peduncles 9 to 12 ecm. 
long, tomentose-pubescent, rather slender; calyx broadly campanulate, 3.5 to +4 
em. long, minutely grayish-tomentose, the lobes narrow, long-acuminate, 2 to 2.5 
em. long; corolla narrowly campanulate, glabrous, yellowish, longitudinally pur- 
plish-veined, with a broad purple spot at the base, 4 to 4.5 em, long, the 
secments 2.5 to 3 em. long, about 12 mm. broad, rounded-subacute at the apex; 
stamens 38, the filaments glabrous, 2 cm. long, the anthers 1 cm. long; pistil- 
lodium apparently none. 
Pistillate flower and fruit not known. 
Type in the U. 8. National Herbarium, no. 533953, collected in Santa Marta, 
Colombia, altitude 2,000 meters, January, 1900, by H. H. Smith (no. 1603). 
Calycophysum brevipes Pittier, sp. nov. PLATES 27-30, 
A robust vine, subligneous and up to 7 cm. thick at the base, ramose, the 
branchlets angular, sulcate, villous or villosulous. Leaves membranous, light 
green and more or less pilosulous above, pale green and densely tomentose- 
pubescent beneath, the petioles 3 to 4 cm, long, tomentose-pubescent, the blades 
subtrilobate, 7 to 18 cm. long, 10 to 14 cm. broad, the lateral lobes rounded or 
subacute, the median lobe longer, triangular, acute, the basal sinus rather 
narrow, rounded, 1.5 to 2.5 em. deep, 1 to 2 cm. broad; tendrils 3 or 4-branched, 
stout, more or less tomentose, the petiolar part 1 to 4 em. long. 
Flowers solitary in the axils, the peduncles and calyx tomentose ; calyx 3.5 
long, the segments 2.5 to 3 cm. long, 10 to 12 mm. broad at the base, acuminate; 
corolla pale reddish white, about 4.2 cm. long, the lobes reflexed, subobtuse at 
the apex, 5 to 7-ribbed, more or less pubescent on the ribs without, 1.5 to 2 
cm. long, 6 to 7 mm. broad at the base. Male flowers immature, the peduncles
