PHILIPPINE SPECIES 



Trematodon capillipes CMiill. Luzon: Mariveles Mountain, 



1267. 

 Dicranella {Anisothecium) Leibergii sp. nov. 



Growing in rather soft, not very compact, brownish green 

 mats; stems short, 4-5 mm. long and simple or sometimes with a 

 single branch up to i cm. long; leaves laxly spreading-flexuous, 

 narrowly lanceolate, up to 3 mm. long, widest (about 0.35 mm.) 

 near the base and uniformly narrowed to the acute or narrowly 

 obtuse, slightly denticulate apex, the margins below entire and 

 flat or slightly recurved ; costa one sixth or less the width of the 

 leaf -base and nearly or quite percurrent; leaf-cells all more or 

 less linear with slightly thickened walls, the median 6-8 /x wide 

 and often 100 /x long, the basal wider, mostly 10-12 m; perichaetial 

 leaves with loosely clasping, somewhat larger base than those of 

 the stem; seta rather weak, finally reddish, mostly 8-9 mm. long; 

 capsule erect, oval-oblong, 1-1.5 mm. long without lid, becoming 

 cylindric and somewhat contracted under the mouth when old 

 and dry, the exothecal cells with somewhat thickened, nearly 

 straight lateral walls, the median cells 16-20 m wide by 35-60 m 

 long, the stoma ta at the base few or quite lacking; lid obliquely 

 subulate, about 0.75 mm. long; annulus none; peristome-teeth 

 about 250 fi high, regular, lanceolate, reddish brown below and 

 vertically striate, divided about half way down into pale, papillose 

 forks and borne on a basilar membrane scarcely extending above 

 the rim; spores rough, 16 /x in diameter; calyptra cucullate, 

 smooth, extending well down the capsule. 



Polillo Island: May, 1909, 1260. 



In habit this species is much like D. flaccidula Mitt, of Fiji 

 and Samoa, but the latter has an annulus, a different peristome, 

 and spores only 3-4 /x in diameter.
