CALYMPERACEAE.
Syrrhopodon semiliber (Mitt.) Besch. Twigs of trees, Siddhapur ; alt. 1500 ft. rainfall 120 in. (6440).
This apparently extremely rare species has only been found hitherto, I believe, by Parish, near Tavoy, in the Malay Peninsula. The present plant agrees exactly with Parish's plant at Kew. Mitten placed it under Calyrnperes but Bescherelle in litt. ad Paris refers it, no doubt rightly to Syrrhopodon ; the developed peristome points to this genus, and the calyptra also. Mitten describes the calyptra as "thecam ad collum obtegente et basi earn amplexante"; but he must have been misled by an immature or abnormal individual. Among some three dozen capsules in the Kew specimens there are none showing the calyptra as described ; the calyptra is purely that of Syr- rhopodon, and in the mature capsule reaches only about one-third of the way down ; it is perfectly free at the base, and falls off before the lid. The plant is a true Syrrhopodon.
It may be worth mentioning that Mitten's citation of " Rev. D. Parish" throughout the Musci Indiae Orientalis is incorrect. It should be " Eev. C.S.P. Parish."
Calyrnperes Nietneri CM. Var. nov. atro-viride Dixon.
Nigro-viride ; folia sicca magis crispata, circinato-incurva. minora, breviora, leniter tantum dentata.
Hab. On tree, Siddhapur ; 1600 ft. alt.; rainfall 120 in. (6482).
A marked variety but the characters seem insufficient to found a new species.
Calyrnperes Fordii Besch. Decayed tree trunk, Siddhapur, (6486) c. fr. Seems to be a slender form of this rather unsatisfactory species. It is rather curious that the only three species of this inter- esting family should have been collected all at Siddhapur.
