A NEW ALPINIA FROM BORNEO 247 



which, moreover, is nearly always distinctly, though lightly, pli- 

 cate when dry. The exothecium cells are quite distinct, somewhat 

 widely elliptical or rhomboid-hexagonal in the Weisia, with thin 

 walls ; much narrower — elongate rectangular — with very thick 

 walls in the Campylostelium. The latter, also, has a broad 

 annulus, of which I could find no evidence in the Weisia, though 

 I cannot vouch for its absence. 



Finally, the peristome in the two mosses differs toto ccelo. In 

 the Campylostelium it is characteristic of the genus, the teeth 

 divided into long, filiform crura, densely papillose below, smooth 

 above. In Schimper's species they are short and irregular, broad, 

 scarcely divided, remotely and thinly transversely barred, smooth 

 or almost so ; in fact, entirely Weisioid. 



W. Wekvitschii is, in short, a good species. Eoth suggests 

 identity with Eucladium verticillatum var. angustifolium, but 

 the leaf base is quite different. It is more like Gyroweisia 

 linealifolia Kindb., but that, inter alia, is gymnostomous, and 

 has mere highly papillose leaves.

This curious Alpinia belongs to the section Genolophon with 

 crested anthers, a section more abundant in Borneo than else- 

 where. The peculiar adnation of the filament to the claw of the 

 lip is very unusual in the genus, and the very long strap- 

 shaped prolongation of the connective is also a very distinctive 

 character.
