 costa validiuscula, in cuspidem longiusculam subintegram patulam 

 excurrens. Eete chlorophyllosum, e cellulis subrhomboideis, 25- 

 35 /x longis, 8-10 /x latis, parietibus pertenuibus instructum, mar- 

 ginalibus angustioribus, elongate oblongis, basilaribus laxe rect- 

 angularibus. ? Dioicum. Seta tenuis, pallide rubra, 1-1-5 cm. 

 alta. Theca erecta, symmetrica, parva, vix 2 mm. longa, collo 

 brevi, in setam subahrwpte defluente, superne latior, sicca sub 

 orificium breviter distincte angustata. Calyptra parva, vix sub 

 orificium producta. Exothecii cellulae irregulares, parietibus

Hab. 'Closely intermixed with Philonotis imbricatula Mitt, on 

 rocks, Muttikulam Gap, Attapadi Hills, Coimbatore, alt. 3100 ft., 

 Sept. 1910; leg. C. E. C. Fischer (no. 4), c.fr. 



Closely allied to B. Borgenianum Hampe, of Madagascar and 

 Mauritius, but having the leaves wider above and not or scarcely 

 acuminate, the cells slightly narrower, the nerve more longiy 

 excurrent, the capsule smaller and shorter, and in proportion 

 wider. B. squarrosulum Card., a recently described American 

 species, is also near it, but has the capsules inclined and some- 

 what asymmetric, and considerably larger. B. Walkeri Broth, 

 has the seta longer, and the capsule much longer, and with a long 

 narrow tapering neck. 



The capsule is noticeable in the dry state from having the 

 orifice much contracted, being narrower than the base of the 

 operculum, and so forming a sort of neck between this and the 

 expanded part of the sporangium. 



B. TURGiDUM Broth. Mahableshwar, 1909 (nos. 64, 65) ; 

 Panchgani, 1909 (no. 66) ; on Euphorbia, Fort Purandhar, 1910 

 (no. 84) ; all c. fr. ; leg. Sedgwick. No. 64 has tho capsules a 

 little less turgid and more erect than in previous gatherings, and 

 the seta longer ; (65) has both forms of capsule, with the longer 

 seta ; (84) has the leaves somewliat longer and slightly falcate. 



B. Walkeri Broth. Stones, Panchgani, Feb. 1909; leg. 

 Sedgwick (no. 52), c. fr. Det. Brotherus.
