86 ASPLENIUM, § EUASPLENIUM. 



unequally attenuated into a glabrous stipes 2-3 inches long, 

 the margin obscurely crcnulate, veins nearly horizontal ap- 

 proximate, sori narrow-linear crowded reaching nearly to the 

 margin and occupying the whole length of the frond, invo- 

 lucres very narrow. — (The above character is taken from a 

 specimen communicated by Blumc.) — Var. /3 majus ; por- 

 tions of specimens (all wanting stipes and lower part of the 

 frond) 14 to 2 feet long and 2-.3 inches wide, nearly the 

 entire of the under side exhibiting a mass of parallel and 

 nearly horizontal lines of fructification frequently extending 

 quite to the margin. — Bl. En. F'd.Jav. p. 175. A. vittoeforme,

Ilab. Mountain woods, Java, Blume, in Herb. Nosh: Isle of Leyte, Philippine 

 Islands, Cuming, n. 308. — Var. majus. Angau, Naviti, and Ovolau, Feejee 

 Islands, Milne, n. 204, 246, 291, and 309.— Wlietlier or not it he owing to tiie 

 brittleness of this plant, it is the case that all the specimens, some of them i)retty 

 large too, are more or less broken ; Dr. Blume's specimens alone possessing the 

 stipes and even a ])ortion of the caude.x. Cuming's specimen has neither base nor 

 apex, yet it seems identical with A. Sundense: a remarkable feature in which is 

 the copious and very compact, nearly equal, prominent, and almost horizontal hnes 

 of fructification. Milne's specimens are all much larger than our Java plant ; in 

 them the fructification is much advanced, and the sori almost conceal the frond. 

 In that state the frond becomes somewhat chartaceous and more opaque. 



16. A. (Euasplenium) Amboinense, Brack, (an Willd. ?) ; 

 caudex creeping moderately stout rooting and densely clothed 

 as is the base of the stipes with subulate black scales, fronds 

 a foot and rather more long 1^ inch wide submembranaceous 

 lanceolate suddenly contracted at the apex into a narrow 

 caudate acumen and there gemmiferous,* below gradually 

 attenuated into a short winged stipes, the margin subentire 

 or subcrenate especially towards the apex, veins horizontally 

 patent, sori subdistant and rather irregular often extending 

 to the margin, involucres narrow-membranaceous. — IVilld.

* I suspect the abruptly caudate apex of this and some allied species of Asple- 

 nium (for I believe it is not invariably present) is occasioned by the formation of 

 a gemma, which absorbs the nourishment, and gives this form to the point. 



t In consulting the beautiful plates of this work, the student needs to be in- 

 formed that it is the practice, where there are two species on a plate, to put the 

 wrong name immediately under i\\c species. In t. 19, for example, the left-hand 

 figure is No. 2, " A. Atuboineme," and under it is written, " 1. A. Fejeense:" 

 and the name A. Amboinense is written under A. Fejeense.
