Hal). Penang and Singapore, Wallich, Sir Wm. A'orris. Java, Blame. Borneo, 

 Thos. Lobb. — This lias much narrower sterile fronds than G. heterocarpa (our n. 

 72), and, I helieve, is very distinct. I may here mention a species of Selliguea 

 of Brackenridge with which I am unacquainted ; S. aliena, " caudex creeping, 

 stipites elongated marginate, fronds entire glabrous membranaceous lanceolate 

 caudato-acuininate attenuate at tlie base repand at the margin, sori oblique con- 

 tinuous scarcely extended to the margin." — Brack. Fil. U. S. Expl. Exped. p. 58. 

 Hab. Luzon. " Closely related to Cclerach pan'iculala " (pedtmculata ?), " Ilook. 

 and Grev., and to Grammitis membranacea, Bl." 



69. G. (Selliguea) macrophylla, Bl. ; caudex " creeping pa- 

 leaceous, stipites .3 to 8 inches in the fertile plant," fronds 

 membranaceous 12-16 inches long 3-3^ inches broad oblongo- 

 lanceolate or oblongo-subspathulate shortly acuminate at the 

 base gradually and rather long-attenuated upon the stipes 

 entire or subsinuate at the margin subopaque, venation ma- 

 nifest, primary veins costuliform subhorizontally patent, a 

 slenderer intermediate soriferous vein runs parallel with 

 them, and all are connected by transverse veins thus forming 

 nearly four-sided subuniform areoles often including free vein- 

 lets, sori alternating with the parallel veins equally long entire 

 or interrupted. — Grammitis, Bl. En. Fil. Jav. p. 119. Selli- 

 guea, Bl. Fil. Jav. p. 127. t. 53 [very faithful). Colysis, Pr.

Hab. Java, Blame. Isle of Bohol, Philipi)inc Islands, Cuming, n. 351. Bor- 

 neo, forests at Sarawak, Thos. Lobb (more sharply acuminated and the fertile 

 frond more ovate). — The finest species perhaps of the group. 



70. G. (Selliguea) membranacea, Bl. ; caudex creej)ing 

 branched the young branches paleaceous with subulate black 

 scales, stipites remote 2-6 inches long, fronds 6-12 inches 

 long ^-1^ inch wide lanceolate acuminate firm-membrana- 

 ceous glabrous almost black when dry, the base long attenu- 

 ated and narrow decurrent on the stipes, primary veins slen- 

 der subcostuliform united by secondary ones forming hexa- 

 gonal subuniform areoles, sori patent linear extending from 

 near the costa to near the margin. — Grammitis, Bl. En. Fil.

 two species out of Cuming's specimen, but, I think, without sufficient reason.
