MACOUN.] CATALOGUE OF CANADIAN PLANTS. 177 



margins recurved at the angles ; cells not distinctly chlorophyllose, 

 narrow, fusiform-lanceolate or sub-linear, also the inner basal ; alar cells 

 numerous, well-defined and quadrate ; costa none or short and double. 

 Perichetial leaves long subulate-acuminate, faintly denticulate at the 

 acumen. Monoecious, 



On logs, Tay, York Co., N.B. {J. Moser.) On old logs in McKay's 

 woods at Ottawa ; very abundant on old logs at Carleton Place, 30 

 miles west of Ottawa; on stones at Britannia, six miles west of Ottawa ; 

 common on old logs at Belleville, Leamington and Owen Sound, Ont. 

 (Macoun.) Trunks of trees, Upper Canada (Ontario). {Dru7nmond.) 

 Common on old logs at London, Ont. (J. Deamess) 



(667.) E. Macounii, C. M. & Kindb. (n. sp.) 



Cylindrothecium Drummondii, Canadian Musci, No. 436. 



Tufts loose. Stem sparingly divided, translucent (visible, in a dry 

 state, through the leaves) ; branches much compressed, elongate, 

 not attenuate, shining green above. Leaves patent, concave, short, 

 ovate-lanceolate, attenuate to a short subulate point ; basal angles 

 rounded ; margins scarcely recurved below, faintlj^ denticulate all 

 around ; cells faintly chlorophyllose, long-sublinear, the lowest basal 

 dilated, oblong or the alar often subquadrate ; costa none or very short 

 and double. Perichetial leaves small, convolute or connivent, longer 

 acuminate, more distinctly denticulate at the apex. Dioecious. 



The species is quite distinct ; Entodon Drummondii differs in the 

 leaves being obtusate, nearly entire, &c. 



On earth in the " Big Swamp," Murray, Northumberland Co., Ont., 

 October 7th, 1888. (Macoun.) 



(668.) E. (Raphidostegium ?) expallens, C. M. & Kindb. 

 (n. sp.) 



Tufts loose, pale yellow. Stems sparingly divided, radiculose 

 at the base. Branches elongate, much compressed, not attenuate. 

 Leaves sub-distichous, patent, short ovate-lanceolate, acute, concave, 

 nearly entire, denticulate only at the apex, distinctly auriculate, not 

 recurved at the margins ; cells not chlorophyllose, long-sublinear, the 

 inner basal dilated sub-oblong ; auricles excavate, well-defined with large, 

 oval or roundish, finally golden-yellow cells ; costa none or double, 

 sometimes reaching to the middle. Barren. 



This species could perhaps be related to the genus Raphidostegium, 

 but the leaves are not recurved at the margins ; the plant is more 

 robust and resembles Entodon Macounii in habit. 



In boggy soil in wet woods at Stephen, summit of Eacky Mountains, 

 July 23rd, 1885. {Macmn.) 12
