Cat. No. 231 is meant, as A . yectimtum , Wall. Cat. 231. with some A. ni gripes, 
is mixed). 
Moore, in the Index Filicum , gives Allantodia (?) tenella , Wall, as a synonym 
of Athyrium tenuifrons , Moore. 
26. A. rupicola, n. sp„ — Plants isolated; caud. suberect or procumbent, 
slow-growing ; st. densely tufted, springing from all round the caudex, short and 
thick and curving towards the vertical, the bases persistent, clothed with 
narrow hair-pointed dull brown scales, above glabrous ; fr. narrow lanceolate, 
acuminate at apex, simply pinnate, deeply pinnatifid, naked except for a few 
fibrillse on main rhachis, herbaceous to subcoriaceous, generally curving 
laterally near the base reversely from the direction of the stipes, the lower 
pinnm becoming distant and dwindling in size ; up to 15 in. 1. and probably 
more, by 3 — 4 in. bi\, rarely broader ; pinn. 20 or more pairs besides apes', 
becoming distant towards the base of the frond, sessile and decurrent both 
ways on rhachis which becomes winged towards apex, f — f in. br., falcate, 
broadest at base and anterior lowest segment longest cut down sometimes 
nearly to the secondary rhachis into broad falcate segments spinulosely toothed 
at point and on both sides, or, in large specimens, lobed, and then the lobes 
spinulosely toothed in correspondence with the veinlets ; ven. pinnate in the 
segments ; vdnlets one to each tooth or lobe, and forked in the lobes ; vena- 
tion distinct on the lower surface ; sori one to each vein, on the anterior 
veinlet of each lobe, or in the fork of the veinlets, short, straight, or some- 
times hippocrepiform,, looking large and roundish when ripe ; invol. brown, 
persistent at least till sori ripen. (Plate V.) 
The above description has been written from fifteen sheets in my possession: 
there is no other description, except that Beddome gives A. rupicola , Edgew., as 
a synonym of A. Filix-jcemim , var. retusa , Clarke, which he describes briefly. 
Some at least of Clarke’s retusa is quite different from the present species.

This is a very distinct species, both in structure and habit. It grows in 
the crevices, of dry exposed rocks, and, late in the season at least, always has
