142 REMARKS ON SOME RARE MOSSES 



drying my collection, I became impatient to proceed to 

 the mountains. Accordingly, on the 25th of June I took 

 my departure from Pau for the Eaux Bonnes, and from that 

 epoch until the 12th of November, I have relaxed not a 

 moment in my exploration of the most Alpine portions of 

 the chain.

Remarks on some rare Mosses of the Southern Hemisphere; 

 by W. Wilson, Esq. 



(Tabs. Ill, IV.) 

 Goniomitritjm (Hook, et Wils.): acrocarpum. Peristomium 

 nullum. Calyptra campanulata, magna, speciosa, 8-cos- 

 tata, junior plicata. 

 1. Goniomitrium enerve (Hook, et Wils.) ; caule brevissimo 

 simplici, foliis late ovatis concavis enerviis, capsula sub- 

 sessili globosa, calyptra costis prominentibus. Tab. III. A. 

 Hab. Swan River, James Drummond; on a red soil. n. 6 (a). 

 Caules gregarii, vix lineares, simplici. Folia laxe imbricata, 

 concava, acuminulata, integerrima, albescentia, siccitate 

 haud contractilia, areolis laxis rhomboideis, perichsetialia 

 longiora, conniventia. Vaginula cylindrica. Capsula fo- 

 liis u immersa, subsessilis, rufo-badia, ore subcoarctata« 

 Annulus nullus. Operculum planiusculum. Sporee luteae, 

 majusculae, numerosae. Calyptra capsulam totam obtegens, 

 albida, membranacea, costis subalaribus. Florescentia 

 monoica, antheridia in perichaetii foliis axillaria, clavata, 

 pedicellata, exapophysata. 



This Moss has much of the habit and character of Ante- 

 tangium repens (Hook. Muse. Exot. t. 106), but is essentially 

 distinguished by its large-ribbed calyptra, and its conside- 

 rably smaller sporules and naked axillary antheridia ; also by 

 the absence of creeping rhizoma. It is probably annual.
