43(i REMARKS ON DRUMMOND's MUSCI AMERICANI. 



74. W. macrocarpa, nov. sp — This is most probably Weissia 

 elongata, Hook. Muse. E.rot. t. 102., which seems not to be 

 truly distinct from W, Mielichoferi, Schwaegr. Suppl. ii. 1. 

 p. 47. f. 114. 



75. Pterogonium intricatum, Hedw. — The greater part of 

 tlie specimens belong to Pterogonium ascendens^ Schwaegr. 

 Suppl. t. 242. a, but the peristome is certainly that of Neckera, 

 and the Moss may be only one of the American forms of 

 Neckera sericea, perhaps the same as the one called Pt. Caro^ 

 litiianum, Bridel, Br. Univ. vol. ii. p. 184. It comes very near 

 to No. 159 of this series. Some of the specimens given for 

 P. intricatum belong to Leskea pobjanthos, a Moss very nearly 

 allied, and scarcely distinguishable, except by an attentive ex- 

 amination of the peristome. 



76. P. intricatum, var. laxum Certainly P. suhcapillatim, 



Hedw, Sp. M. t. 16, having a scabrous seta. 



80. Dicranum scoparium, — Some, if not most, of the speci- 

 mens are probably varieties of i),ScAraJm; (compare No. 87.) 



82. D.fuscescens, — Tlie specimens probably belong to Z>. 

 congestum, Schwaegr. t. 42. The same Moss is found in 

 Scotland. 



84. D. Starkii, var. major. — These specimens appear to be 

 also D. congestum, Schwaegr. ; the capsule is destitute of 

 struma, and the leaves are serrated. 



86. D. undulatum, var. — Probably a distinct species. 



88. D. Schraderi, var. major. — These specimens appear to 

 belong to the typical form, well represented in Schwaegr. 

 Suppl. ^ 41. 



91. D. elongafum — It is difficult to distinguish any of the 

 specimens here given from D. sfrictum, No. 81, and some of 

 them are exactly similar. If there be any real difference it 

 will be found in the rather shorter and inclined capsule of Z>. 

 elongatum, and in the foliage, which is very erect and almost 

 appressed to the stem when wet, and slightly crisped in a dry 

 state. 



92. D. elongatum, var. 7ninor. — No observable difference 

 between this and J), strictum.
