84 ASPLENIUM, § EUASPLENIUM. 



perfect at the l)asc) 21 feet long 2i inches wide glabrous firm 

 cJKirtaccous dark-green ratiier glossy on both sides loriforni- 

 lanceolate acuminate quite entire from below the middle 

 gradually aud long-attenuated, veins rather distant horizon- 

 tally patent unusually prominent on both sides (so that 

 they are sensible to the touch) and conspicuous, sori narrow- 

 linear copious terminating short of the margin, involucres 

 very narrow. 



Ilab. South tropical Western Africa, near Elephant's Bay, Dr. Curror. This is 

 another south tropical Aspleninm which I can refer to no described known species, 

 aud to which, from its size, like many others, it wouhl not l)e possible to do 

 justice by a figure in a work like this. It may rank near ^1. sinnatinn and A. 

 Cnrrori, yet has a habit and form and size and colour (difhcult as these may be 

 to define in words) which forbid my uniting it with any species known to me. 

 The very distinct and prominent, and, if I may so say, tangible venation, is a 

 remarkable feature, as is the very long tapering base (both specimens unfortu- 

 nately are destitute of stipes). The veins extend to the slightly thickened mar- 

 gin, and appear to unite with it : but there is no intramarginal vein, as in the 

 Thamnopterh group. 



13. A. (Euasplenium) scohpendrioitles, J. Sm. ; fronds 

 simple lanceolate chartaceo-niembranaceous (in our only 

 ])erfect specimen suddenly caudato-acuminate) entire or very 

 obscurely serrated towards the apex, much and gradually 

 tapering at the base into a short stipes on which are a few 

 small appressed scales, veins rather distant horizontally j^a- 

 tent, sori moderately broad linear, involucres of i/ic same 

 colour and texture as the frond, when dehiscent leaving a dis- 

 tinct elevated I'tne upon the frond corresponding tvith its at- 

 tachment before separating. — /. Sin. in Hook. Journ. Bot.

My figures and descriptions in Ic. Plant, were taken from a solitary speci- 

 men of this plant, which presents at first sight no very remarkable feature 

 in form, venation, etc., I should have had no hesitation in considering it A. 

 Snnden-se, Bl. {A. Fejecnsc, 15rack. in Fil. U. S. Expl. Expedition), but for a pe- 

 culiarity in the sori, which I thus characterized: " Soris linearibns, involucris 

 subgcminatis superiore angustissimo veniformi" {rimiformi in Ic. PI. by mis- 

 print) : and again, in the observations, I remarked of the involucres, that " on 

 the inner and upper side a uerve-likc line will he seen to run parallel with, 

 and of the same length as, the involucre, leaving a narrow area between it and 

 the insertion of the involucre on the vein: this line is caused by a slender mem- 

 brane, evidently a portion of the involucre, remaining after the dehiscence." 

 Mettenius, who does not aj)pear to have seen a specimen, seems to object to my
