448 ON THE NEW SPECIES OF MUSCI. 



Gymnostomum infleantm appears to be the same as Weissia 

 mucronata, (Nees et Hornsch.), except in the absence of a 

 peristome. 



Gymnostomum apophysatum, is a Physcomitrium, folns 

 ovatis acuminatis suhintegris evanidinerviis, capsula clavata. 



Leptostomum squarrosum, has a double peristome, and the 

 habit is that of Paludella. The sulcate capsule, however, 

 shews it to be an Aulocamnion. — (A. flexifolium, Hook, et 

 Wils. MSS.), foliis pentastichis flexuosis ovato-oblongis api- 

 culatis subsolidinerviis. (Tab. XV. G.) — It differs from A- 

 pentastichum, (Montague), in the shorter fiexuose leaves, and 

 from Paludella squarrosa in the absence of serratures, and in 

 the striated capsule. 



Brachymitrium Jamesoni, (Tab. XV. A.), belongs to the 

 order of Splachnacea, and appears to be a species of Ere- 

 modon, (Bridel), or perhaps of Tayloria, (Bruch et Schimper), 

 from which it differs merely in the scabrous calyptra. It i s 

 allied to Tayloria Rudolphiana. Another curious species has 

 been sent from South America by Mr. Lobb.* 



* Eremodon spathulatus, (Hook, et Wils.) ; foliis spathulatis argute ser- 

 ratis evanidinerviis siccitate undulato-crispatis, seta breviuscula, capsula 

 cylindrica exapophysata, operculo conico-apiculato brevi, calyptra nu- 

 triformi hirta basi appendiculata. (Tab. XV. B.) 

 Hab. South America. Mr. Lobb, 105. 



Stems balf an inch long and more, with purplish radicles. Leaves not 

 expanding in water. Teeth of the peristome in 8 pairs, horizontal, P^ e > 

 not reflexed when dry. No annulus. The inflorescence is monoicous, the 

 male flower capituliform. 



In all the Splachna hitherto examined, the sporules are arranged i» 

 a very peculiar manner : they are lodged in cells radiating from the colu- 

 mella, to the number of eight or nine. The knowledge of this fact supp» es 

 a ready solution of the difficulty mentioned by Dr. Montagne in Annates 

 des Sciences Nat., Aug. 1845, ] 19. Weissia (Encamptodon) perichatiafat 

 (Mont.) is evidently a Splachnoid Moss, of which he remarks : " Q uell f 

 n'a pas 4t6 ma surprise, en cherchant a connaitre les spores, de trouver a 

 leur place, des especes de gemmes analogues a celles qu'on rencontre dans 

 les corbeilles des Marchantices. Toutes les urnes que j'ai ouvertes e n 

 e'taient completement remplies. Cea gemmes sont cuneiformes ou pa""'
