TWO NEW FERNS FROM JAMAICA 



By B. D. Gilbert. 



ASPLENIUM Glutei. Caudex short with copious fibrillose rad- 

 icles and minutely paleaceous at the summit. Stipites clus- 

 tered, prostrate, i-3mm. long, with minute filiform scales; 

 laminae 1 -4cm. long, 4-6mm. wide, pinnate; rachis filiform green, 

 compressed, slightly winged in the upper part; texture thin, mem- 

 branaceous; pinna? 6 12 pairs distinctly stalked on the lower two- 

 thirds of the frond, above that slightly adnate-decurrent, wedge- 

 shaped or flabellate, 3-4mm. long, i-3tnm. wide, terminal one 

 cuneate flabellate, two lobed, blunt, those next below obovate, 

 entire ; lower ones obcordate with a single vein in each lobe or 

 occasionally the vein in the lower lobe once forked. Sori gener- 

 ally one on the exterior vein opening toward the inferior vein, 

 sometime one in each lobe large for the size of the pinnae; indus- 

 ium, when young, light green nearly the same color as the pinnae, 

 greenish-white in age slightly fimbriate on the edge. 



Aspienium Clutei, Natural Size. 



An extremely delicate and tiny fern as thin and translucent 

 as a filmy, no larger than A. pygnuvum Hook., which that author 

 characterized as 41 the smallest of the ferns (save in Hymeno- 

 phyllacecp')" prettier in form than that species and nearer to A. 

 Projection Kze. It differs from the latter in the shape of the pin- 

 nae and in not having a proliferous apex. At first sight it recalls 

 PolyPodium e.xiguum Griesb., being about the same size as that
