TRIBE I. (§ 13) GYMNOGRAMME^. 
a. Veins free. 
Grammitis, Swartz, Schrad. Journ. 1800. II. 3, 17. 
(Cliilopteris, P^-esl. ; Pleurogramma, R. Brown ; Leptogramma, J. Smith ; Tricliothemelium, Kmze ; Trichocalymma, Zenker ; 
Gymnogrammatis, Sp. Auct.) 
Sori non-indusiate, oblong or elliptic, oblique ; the receptacles medial or sub-terminal. Veins .simple or forked from a central 
costa — Venules free. 
Fronds simple pinnate or Iji-pinnate, herbaceous or sub-coriaceous, the rachis sometimes proliferous, Rhizome short, erect, some- 
times short or elongate creeping — (Moore). 
1. Grammitis totta (Presl.) caudex short, stout, erect, stipites tufted copiously scaly below, clothed with soft white hairs above, 
more or less angled : frond elliptic-lanceolate a span to 3 feet in length, membranaceous pinnate, with the pinnse pinnatifid \ way down 
to the rachis, hairy on both sides and ciliate, venules pinnate from a central vein simple or forked — sori copious, turning quite black when 
ripe, occupying the whole of the lower venules and the centre of the upper ones, spore-cases hairy. Gijmnogravima totta. Schlech. 
Very common about Ootacamund on the Nilgiris — Puluey hills at the same elevation. 
PLATE No. XLIX. 
B. Veins uniform reticulated luith free included veinlets. 
LoxoGRAMMA, Blume, Flora, Java 73. 
Sori non-indusiate, oblong or linear, oblique, the elongate receptacles medial at intervals between the costa and margin. Veins 
uniform, reticulated from a central costa, the venules forming unequal oblique hexagonal elongated areoles, with (rarely without) included 
free veinlets. 
Fronds simple coriaceous or sub-coriaceous. Rhizome creeping — The veins are often indistinct, being immersed in the sub- 
stance of the thickish fronds.— The uniformly reticulated venation distinguishes this genus from Selliguea, in which the veins are pinnate 
and prominent. (Moore.) 
1. Loxogramma involuta (Presl.) ; Rhizome creeping furnished with numerous scales and wiry hairy roots — fronds coriaceous 
lanceolate 10-14 inch long, about 1 inch broad, acuminated at the apex and gradually attenuated at the base into the stipe, margins more or 
less involute sori linear, oblique from the costa, all situated on the upper half of the frond — free included veinlets numerous. Gram- 
mitis involuta. Don — Selliguea involuta. Kunze. 
Very abundant on the higher ranges of the Nilgiris and other mountains on the western side of the Presidency, on rocks and 
trunks of trees. 
PLATE No. L. 
2. Loxogramma lanceolata ( tresl.) Rhizome creeping, scaly furnished with Aviry haiiy roots — fronds sub-coriaceous 4 to 7 
inches long, about \ an inch broad, acuminate at the apex, attenuated at the base ; sori oblong, slightly oblique or nearly parallel with the 
costa, often continued to nearly the base of the ixoxvd.— Grammitis lanceolata, Siv. 
Nilgiris — Neddiwattau on trees — much rarer than the last species. 
PLATE No. LI. 
TRIBE I (§ 12) HEMIONITIDE^. 
Veins uniform reticulated. 
Antrophyum, Kaulfuss, Emm., Fil., 197. 
Sori non-indusiate, usually immersed, sometimes superficial, narrow-linear, occupying the anastomosed veins which form the 
sides of the areoles, mostly united ; the receptacles therefore partially, though generally reticulated, Veins uniformly reticulated from a 
costa, or ecostate, forming sub-hexagonal areoles.
