396 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Type in the U. 8S. National Herbarium, no. 828705, collected in forest south of and 
above Amalfi, Colombia, altitude 2,000 meters, October, 1884, by F. C. Lehmann 
(no. XLII). 
ADDITIONAL SPECIMEN EXAMINED: 
Cotomst1a: Western range of mountains above the City of Cali, alt. 1,800 to 2,200 
meters, Lehmann 5165. 
Related to O. guatemalensis, as mentioned under that species. 
6. Oleandra decurrens Maxon, sp. nov. 
Rhizome scandent, 2 to 3 mm. thick, sparingly branched, closely and densely 
appressed-paleaceous, the scales lance-attenuate, bright castaneous throughout, at 
first laxly short-fibrillose; phyllopodia mostly subfasciculate at intervals, stout, short 
(1 to 1.5 mm. long), nearly or quite as broad, oblique, densely paleaceous; fronds 
sessile or nearly so, the stipe never more than 5 mm. long; lamina 15 to 23 cm. long, 
2 to 2.8 cm. broad, linear-oblanceolate, acuminate-caudate, tapering gradually from 
the apical third to a slender long-attenuate alate base; costa prominent, relatively 
slender, densely but minutely glandular-pubescent, delicately paleaceous nearly 
throughout, the scales spreading, linear-lanceolate, long-attenuate, 1.5 to 2 mm. long, 
bright yellowish brown, the lower ones more or less fibrillose; veins arising mostly in 
2’s, simple or forked below the middle, 22 to 26 per centimeter near the margin; 
sori less than 1 mm. broad, mostly scattering, 2 to 6 mm. from the costa, forming a very 
irregular double row; indusia orbicular-reniform, small, long-ciliate and copiously 
pilose. Leaftissue rigidly herbaceous, minutely pubescent (conspicuously so beneath), 
the margins slightly cartilaginous, persistently ciliate. 
Type in the U. 8. National Herbarium, no. 828702, collected at El General, Costa 
Rica, January, 1897, by H. Pittier (no. 10649). 
A strongly marked species, unique among related species of this group in its long- 
decurrent, nearly or quite exstipitate fronds. 
7. Oleandra pilosa Hook. in Hook. & Bauer, Gen. Fil. pl. 45. B. 1840. 
Type Locauity: Berbice, British Guiana (Schomburghk 416). 
DistrisuTion: Apparently known only from the three Guianas and Colombia. 
Intustrations: Hook. & Bauer, loc. cit.; Karst. Fl. Columb. 1: pl. 73. /. 6, 7. 
In general appearance this species somewhat resembles O. costaricensis and O. trini- 
tensis. It is immediately distinguished from them by its long-ciliate indusia.

8. Oleandra panamensis Maxon, sp. nov. 
Rhizome scandent, 2 to 4 mm. in diameter, densely appressed-paleaceous, the 
scales closely imbricate, lance-subulate, castaneous, at first conspicuously crinite- 
filamentous; phyllopodia subfasciculate in distant zones, 2 to 3 mm. long, stout, 
oblique, knob-like, paleaceous; stipes 1 to 1.5 cm. long, olivaceous; lamina 28 to 38 
cm. long, 2.5 to 3.5 cm. broad, narrowly linear-oblanceolate, subfalcate, acuminate, 
long-caudate, tapering very gradually from above the middle downward to the nar- 
rowly cuneate (not long-attenuate) base; costa strongly elevated, stout, olivaceous, 
conspicuously glandular-pubescent, sparsely paleaceous nearly throughout, the scales 
spreading, lanceolate-attenuate from a broader base, hair-pointed, conspicuously 
glandular-fimbriate, or the lower ones slightly broader at the base, darker, and some- 
what crinite-fibrillose; veins arising in 2’s or 3’s, many of them forked at or below the 
middle, not close, 16 or 17 per centimeter near the margin; sori about 1 mm. broad, 
apart, 2 to 6 mm. distant from the costa, more than half of them arranged in an irregular
