I., rarely longer, 3—6 in. br. ; pinn. 10—18 pairs (according to size of frond) 
besides the acuminate apex, well apart, stalked, ovate-acuminate, 11 — 3 in. I, 
2—1 in. br., sometimes broadest at base, generally like the frond in miniature ; 
secondary rhaehis flat above, keeled below, becoming winged above the lowest 
few pahs of pinnules ; pinril. 6 — 12 pairs below the acuminate apex of 
the pinna, oblong and blunt to falcate, unequal-sided, lower side cut away, 
divided more or less deeply into 4 — 6 pairs of blunt toothed lobes or segments ; 
upper surface furnished with long weak setce springing from the sides of the 
secondary rhaehis and the costa of the pinnule, and in large fronds also from the 
veins • texture herbaceous ; ven, pinnate in the pinnules, and forking in the 
ultimate segments ; son in a double row close to the costa along the vein and 
the superior veiulet of each lobe, sometimes one, jr a pair, away from the costa 
in the anterior lowest segment ; invol. persistent, opening towards the costa or 
the main vein of the enlarged lowest segment. (Plate IV.)

A small and elegant plant, found on wet rocks, or by the side of small 
streams, in forests on the Himalaya. Intermediate between A. niqripes and 
A. tenwfrons, Wall. Distinguishable from the former by the shorter stipes, more 
delicate habit and more elegant cutting, and distinguishable from A. tenwfrons 
by the smaller size of the plant, slender stipes, generally more attenuate pinnae, 
and by not being proliferous towards' the apex of the fronds. 
A. tenellum , Wall., is given in Hooker and Baker’s Synopsis Filicum as 
merely a form of A. Filix-fcemina y Bernh., “ with the midrib of the pinnae 
and pinnules beset with firm yellow spines or strigillfe but in the living 
state the two plants are altogether unlike. In the Wallichian collection in 
the Herbarium of the Linnean Society, there is only one frond ticketed by 
WalUch, Allantodia tenella , Wall., “ Legi in Napalia 1821” : it is long and 
narrow — 11^ in. 1., 4in.br., with sori very costal, like the Sikkim high- 
level plant which Mr. Clarke called var, alpina of A. nigripes , and the Khasi 
Hill specimens alluded to in this paper under A. nigripes : the pinna? are distant 
and very narrow — about £in. br. only, and just enough of the upper surface 
is visible to show that it is setnlose. In the British Museum Herbarium 
there are two sheets marked “ AUmtodia t&nslla 9 Wall, in Herb. 131 ” (possibly
