Webera fontana, Kindb. N. sp. 



Allied to W. albicans, but quite green, leaves not decurrent, more 

 denticulate, at least to the middle. Barren. — In wet springy places at

Bryum pendulum, Schimp. x cylindricum, Kindb. N. Subsp. 



Capsule narrow, cylindric-oblong ; lid deplanate ; spores small, 

 scarcely 0.22 mm. long ; flowers dioecious ; stem-leaves ovate; costa red,

Thelia compacta, Kindb N. sp. 



Stems closely creeping. Tufts green, very dense and thick. Branches 

 erect, terete, obtuse and unilateral. Leaves cochleariform, rotundate- 

 obtuse and short-apiculate, very scabrous at the back, with simple in- 

 curved papillifei-ous cilia? ; borders spinulose-dentate or fimbria te- 

 ciliate ; cilise long, curved up and dentate ; costa obsolete or very short. 

 Perichetial leaves oblong-lanceolate, narrowly-acuminate, fimbriate. 

 Capsule pale-brown, ovate-cylindrical ; teeth subulate, short and broad, 

 horizontally divaricate when moist, distantly articulate, dusky, the top 

 article cleft ; basilar membrane short, scarcely \ the length of the teeth, 

 without segments ; operculum conic obtuse, not curved, J the length of 

 the capsule ; pedicel smooth scarcely 1 cm. long. Differs from Thelia 

 hirtella in the longer branches, the larger and more pellucid leaves, the 

 greater leaf-cells and the longer, thicker capsule, also in the peristome.
