the lamellae in transverse section is flattened and often emarginate. 

 The capsule is distinctly ribbed when fresh, and plicate when dry 

 and old, as figured and described in the Bry. Jav. Several of the 

 Indian specimens I have seen under this name have the capsules 

 smooth. Other species of Pogonatwn appear to exhibit the same 

 dimorphism in the capsule. If this is admitted, together with the 

 liability of the terminal cell of lamellae of P. aloides to the varia- 

 tion pointed out by Salmon (Journ. Linn. Soc. Bot. xxxiv. 463), and 

 the well-known polymorphism of this and P. suhrotundum as to 

 general height, length of seta, and outline of capsule, 'it appears 

 evident that several of the Indian species are founded on unstable 

 characters, and a large and rather welcome reduction of species 

 may be ultimately looked for.

Pogonatum papillosulum Card. & Dixon, sp. nov. (Tab. 517, 

 fig. 1.) Fusco-viride, sat conferte caespitosum. Caulis simplex 

 vel sub perichaetio innovans, 2-4 cm. alius, rigidiusculus. Folia 

 sat conferta, humida erecto-patentia, sicca fortiter incurva vix 

 contorta, subrigida ; 3-4 mm. longa, e basi brevi subito in laminam 

 lanceolatam latiusculam angustata, apice acuto, marginibus nunc 

 obscure nunc argute per partem folii dimidiam superiorem den- 

 tatis ; costa valida rufa percurrens, dorso prope apicem plus- 

 minusve argute dentihus sublamellosis dentata ; cellulse laminae 

 parvae, incrassatae, 10-14 fx latae, subquadratae, ad basin dilatatam 

 pellucidae, quadratce vel breviter rectangtdares, infimae tantum 

 elongate (3 : 1 vel 4:1). Lamellae 25-35, dense confertae, totam fere 

 laminam obtegentes, sectione transversa e 5-7 cellulis instnictce, 

 cellula terminali majore, dilatata, scepius depressa vel emarginata, 

 minute scepe obscure papillosula. Dioicum ; plantae masculae densius 

 confertse, breviores, foliis brevioribus, rufescentibus ; bracteae ex- 

 ternae latissime triangulares, suborbiculares, infra aurantiaceae, supra 

 hyalinae costa excurrente breviter rufo-cuspidatae ; internae minores, 

 mucronatae. Bract, perich. foliis caulinis similes ; seta 2-2-5 cm. 

 longa, intense rubra ; theca fusco-viridis, subsymmetrica, elliptico- 

 cylindrica laevis nee angulosa, collo distincto tumidiusculo (aetate 

 obscuro), sub ore valde constricta, per totam superficiem papillis 

 acutiusculis obtecta. Calyptra totam thecam obtegens, superne 

 straminea infra pallida.

Belonging to the section Anasmogonmm, and nearest to 

 P. rufisetum and P. infuscatum Mitt., but differing from these and 

 from all others of the section in the subpapillose, flattened and 

 emarginate terminal cells of the lamellae. The solid nerve and 

 dense elevated lamellae give the leaves a rigid texture, so that in 

 the dry state they are less contorted and also less convolute than 

 in most of the allied species. P. rufisetum Mitt, has much less 

 developed lamellae and a narrower nerve. The capsule and 

 calyptra are described from the Darjeeling plant, which is in 

 better condition as regards the fruit, but agrees with the Ghoom
