Anteophtum Beookei, Hook. 



Caudice repente subulato - squamoso densissime olivaceo- 

 tomentoso, frondibus crespitosis membranaceis flaccidis 3- 

 pollicaribus ad spithamasam lineari-lanceolatis acuminatis 

 basi attenuatis sessilibus ecostatis, soris anguste linearibus 

 2-4 sa^pe longe continuis simplicibus nunc interrupts et 

 parce ramosis irnmersis, venis anastomossantibus areolas 

 valde elongatas margini parallelas formantibus, capsulis pilis 

 articulatis intermixtis.

Tbe caudex of this is creeping, but as well as the roots, often 

 densely covered with a mass of olivaceous tomentum, so as 

 scarcely to be visible. Where the tufts of fronds arise the 

 caudex is seen to be paleaceous with subulate scales. Fronds 

 membranaceous, flaccid, three inches to a span, or almost a 

 foot long, one-third of an inch wide in the broadest part, 

 narrow, linear-lanceolate, accuminated, ecostate, much taper- 

 ing below, but not stipitate; a darkish line indeed runs through 

 the very narrow base, but nothing that can be called a mid- 

 rib. The sori vary in form. In one specimen two uninter- 

 rupted longitudinal lines run for a length of five inches between 

 the centre and the margins, and a third but shorter continu- 

 ous line appears between one of these and the margin ; in 

 other specimens the sori form two to four somewhat parallel 

 lines, here and there branched and variously interrupted ; all 

 are sunk in a channel or groove in the substance of the frond, 

 and all arise from the veins which run longitudinally, while 

 oblique veinlets unite them so as to form very elongated 

 areoles. 



I can no where find any Fern described corresponding 

 with this. It seems to approach the Antroph. angustatum of 

 Brackenridge from Tahiti ; but that has a stipes four inches 

 long. It very much resembles in general aspect the Antroph. 

 lineatum, Kaulf. (Polytaenium lineatum, Desv. and Hook. 

 Gen. Fil. Tab. CVIL), but that has copious parallel sori and a 

 distinct costa. Our Antrophyum Galeottti (see Tab. LXX. 

 of this volume), has the areoles and sori oblique.
