292 PROF. OLIVER ON NEW PLANTS FROM RORAIMA. 
at the base. Pinnz about 20 оп a side below the caudate apex of the frond, % in. broad 
at the base, narrowed gradually to an acute point. Sori a line in diameter, 12-16-jugate 
on the lower pinnee. 
Nearest the Andine P. melanopus, Hook. & Grev., from which it differs by its stiffly 
erect stipes, frond broadest at the base, and obscure immersed veins. Found on the 
upper slopes of the mountain, and gathered previously by Kalbreyer on the mountains 
of the province of Ocana, in New Granada, at an elevation of 6500 ft. 
186% (159%), Poryroprum Кооквхамж, Jenman MSS., п. sp.; rhizomate valido bre- 
viter repente vel suberecto paleis subulatis castaneis ciliatis dense vestito, stipitibus 
castaneis elongatis parce ciliatis, frondibus oblongo-lanceolatis subcoriaceis glabris 
simpliciter subpinnatis, rhachide primario anguste alato, pinnis lanceolatis aeutis inte- 
gris basi confluentibus, costis immersis, venis furcatis, soris medialibus obscure 
immersis. 
Stipes 6-9 in. long. Lamina 6-8 in. long, 2 in. broad, truncate at the base, dark green 
above, pale beneath.  Pinn: 16-20 on a side below the subentire acuminate apex of the 
frond, the largest an inch long, 1-1 in. broad. Primary rhachis purpuraceous on both 
sides of the frond. Sori terminal on the anterior fork of each vein. 
This I have not seen, and insert entirely on Mr. Jenman's authority. I have merely 
altered the form of the description which he has sent, so as to make it uniform with the 
others. It did duty for no. 186 in set C of the distribution. Mr. Jenman says it is 
intermediate between P. Kalbreyeri and the Jamaican Р. brunneo-viride.

.917. POLYPODIUM XxANTHOTRICHIUM, Klotzsch СР. ellipticosorum, Fée). Upper slopes 
of the mountain. Appears to be distinct specifically from P. cultratum by its 
uniformly elliptical sori.

176. POLYPODIUM FIRMUM, Klotzsch. Upper slopes of the mountain.

125 (212%. Potypopium ($ EurOLYPODIUM) MELANOTRICHUM, п. sp.; caudice erecto 
. paleis subulatis crispatis vestito, stipite brevissimo gracillimo, frondibus oblongo- 
lanceolatis parvis flaecidis membranaceis glabris bipinnatifidis, pinnis lanceolatis 
adnatis profunde pectinato-pinnatifidis inferioribus sensim minoribus, segmentis 
deltoideis acutis, venis brevibus simplicibus erecto-patentibus, soris globosis super- 
 ficialibus costularibus ad apicem venarum impositis. 
Stipes and rhachis black, thread-like, glabrous. Lamina 3-4 in. long, an inch broad at 
the middle. Central pinnz half an inch long, } in. broad, with 6-8 pairs of deltoid 
segments with a single sorus in the centre of each.
