REPORT ON THE, BOTANY OF THE SOUTH-EASTERN .MOLUCCAS. 213 



Caulis 5 em. ; ramis 4-5 mm. longis cum foliis 2 mm. latis. Folia pallida, luteo- 

 viridia, baud riitida, sicca paruni mutata. Pedunculus ruber, 5 mm. longus. 



Aerou. — Creeping over dead leaves. 



A little smaller than Clicetomitrium rugifolium, Sull. (Bot. U.S. Expl. Exp., p. 23, t. 

 22), with leaves of the branches much narrower. 



Only one capsule seen with operculum, which may not be complete, for in this group 

 the beak is generally prolonged. 



More than thirty species are now known of this curious genus, which in foliage is often 

 similar to some species of Ectvopothecium, and sometimes to that of some Meteoria ; the 

 areolation is in all of very narrow cells like those of Cienidium. In most cases the 

 specimens are too scanty to give an adequate idea of their habit of growth ; some appear 

 to grow in spreading patches, others, as Clicetomitrium philvppinense, Mont., and Chcsto- 

 mitrium volutum, have the main stem creeping and adhering to twigs. These are provided 

 with numerous simple branches which in Clicetomitrium philvppinense curve in various 

 directions and have their foliage imbricate and slightly secund ; but there is another species 

 gathered in Borneo by Motley. 1 



Thuidium plumulosum, Dozy et Molk. 



Thuidium plumulosum, Dozy et Molk., Bryol. Jav., ii.'p. 118. 



Arrotj. — In very small quantity, barren. This species ranges from Java to New Guinea. 



HEPATIC^. 2 



Chiloscyphus argutus, Nees. 



Chiloscyphus argutus, Nees in G. L. et N._ Synopsis Hep., p. 183. 



Arrou. — A single stem only. Widely spread in the southern hemisphere, and extending 

 northward to the Caroline Islands and Nepal. 



1 Clicetomitrium bornense, Mitt., n. sp. — Caulis primarius repens, ramis quamplurimis simplicibua rectis 

 approximatis ; folia dense inserta, in seriebus quinis imbricata, late ovalia, cymbiformia, concava, dorso scabra, 

 apice breviter mucronata, marginibus incurvis serrulatis, . nervis binis brevissiinis ; perichaetium ad ramorum 

 latera, foliis parvis; theca ovalis, suberecta, operculo conico subulate 



Caulis usque ad 2 decim. longus, ubique radicans, rami 2 cm. longi, 1 mm. crassi, nitidi. Pedunculua 3 mm. 

 longus asper. Calyptra generis. 



This approximates very nearly to Mcteorium, especially to tbe species which, like Meteorium tetragonum, 

 have their foliage arranged in a seriate manner, and the resemblance is increased by the shortness of the seta 

 and the nearly erect but unequal-sided capsule ; the peristome has the two cells of the external bands of the 

 teeth confluent, and not divided by an interval through which the internal band is seen, as in the llooketicc.
