than, but at times equal to, that of the Abor specimen ; and the leaves are 
a shade closer, and not markedly fragile, as they are to some extent in 
the latter ; the seta also is a shade shorter ; but the differences are minute 
in comparison with the general agreement, and I do not think it is pos- 
sible to separate them.

Fleischer (Musci..,von Buitenzorg I, 149) cites Hampers description 
of the fruit of this species, which is in some respects rather misleading, 
notably in the terms “ Kapsel klein trocken wenig gestreift.'” 1 have 
examined the fruiting specimens in Hampers herbarium (Borneo, leg. 
Beccari), which shows the capsules exactly as in the Abor plant, by no 
means small for the genus, and quite markedly striate when dry.

From the description of the locality for the type plant, and from 
specimens which I have received from soutnern India, it is evident that 
the normal habitat for this species is within the reach of, and frequently 
overflowed by, water. It varies very greatly, not only in the form of 
leaf but also in the degree of limbation, for though usuall} r quite immar- 
ginate the vaginant lamina may sometimes show a quite distinct though 
narrow border. 
Mr. Burkill informs mo that the Abor plant bears ripe fruit early in December only a 
month, or even less, from the date when it becomes exposed — a very interesting instancO 
of adaptation to the special circumstances of its development.
