160 GYMNOGRAMME, § SELLIGUEA. 



71. G. (Selliguea) Wrightii, Hook.; caudex creeping pa- 

 leaceous witli blackish subulate often falcate small scales, 

 stipites scarcely any or in other words 8-12 inches long but 

 winged almost to the caudex by the gradually decurrent ])ase 

 of the frond, in general the longer are of the fertile fronds, 

 fronds 6-8 inches long before coming to the rather sudden 

 contraction which forms the wings to the stipes almost black 

 when dry glabrous membranaceous opaque exactly lanceolate 

 obtusely acuminate entire remarkably decurrent on the stipes, 

 primary veins costuliform subhorizontally patent between 

 which are two parallel series of rather large oblong-square 

 areoles with or without free veinlets, sori linear rarely inter- 

 rupted yellowish alternating with the costular veins. (Tab. 

 CCCIII.) 



Hab. Loochoo Islands, C. Wright (" Selliguea pedunculata, Pr.") West coast 

 of Formosa, Wilford, Swinhoe. — This is quite diiferent from the Selligtiea pedun- 

 culata of Pr., to which Mr. C. Wright refers it, and a very remarkable species, 

 extremely uniform in the specimens I possess from three different collectors. From 

 the dark opaque hue of the fronds and scales of the caudex, it has the appearance 

 of an aquatic. 



72. G. (Selliguea) heterocarpa, Bl. ; caudex creeping 

 densely clothed with appressed subulato-setaceous scales, 

 stipites distant 6-8-10 inches long stramineous longest of 

 the fertile frond, fronds subcoriaceo-membranaceous and 

 glossy entire more or less acuminate from 10-12 inches 

 long usually all more or less lanceolate or oblongo-lanceolate 

 attenuated and decurrent at the base entire, costules very 

 distinct horizontal connected by transverse veins forming 

 large areoles filled up with a net work of smaller ones with 

 free included veinlets, sori alternating with the costules 

 broad oblong sunk (forming an oblong boss on the upper 

 side) extending neither to the costa nor to the margin. —

Hab. High mountains of Java, Blume, ZoU'mger, Millett, Thns. Lobb. De Vriese 

 and Teijsma7i7i.— This is well figured by Blume, and appears to be peculiar to Java. 



73. G. (Selliguea) Hamiltoniana, Wall. ; caudex creeping 

 partially paleaceous with subulate black scales, stipites dis- 

 tant 2-4 inches long, the sterile fronds a foot and more long 

 and more slender in the fertile, fronds dimorphous subco- 

 riaceo-membranaceous subopaque glabrous sinuato-dentate 

 ovate or ovato-lanceolate acuminate at the base long-attenu-
