438 HKiMARlCS ON DRUMMOND's MUSCI AMERICAN!. 



161. Neckera pennata In one of the sets a Neckera, pro- 

 bably new, allied to A'. Douglasii, Hook. Bot. Misc. v. i. t. 35, 

 was found in company witb this species. The new species is 

 smaller than iV. Douglasii, in habit resembling N. exserta. 



164. Ilypnum denticulatum. — The specimens given have 

 the margins of the leaves evidently reflexed, so as to give the 

 appearance of a border ; this feature has not been observed 

 in British specimens : it may perhaps be found in H. sylvati^ 

 cum which these specimens very much resemble. 



165. H. denticulatum, var. Donianum. — More like the 

 common state of H. denticulatum. Its leaves are certainly 

 acute. In one of the copies there was found substituted for 

 this Moss a beautiful Leskea, with ovate concave cirrhose 

 leaves : it is probably Leskea Jlaccida of Torrey. ( See Bridel, 

 Bryol, Univ. p. ii. 308.) 



166. H. vagans, nov. sp The specimens given have a 



scabrous seta, and are much like H. rutabulum, of which it 

 may be a variety, perhaps var. t,. €xpla7iatitm, of Bridel, 

 Bryol. Univ. v. ii./?. 488. 



168. H. Silesianum. — Some of the specimens seem to be 

 correctly named, but several of them belong to H. pulchel^ 

 lum, having perfectly entire leaves. 



169. H. sericeum. — The substriated leaves rather indicate 

 that this Moss is allied to Leskea imbricatula, Hedw. Sp. M. 

 t. 52. 



174. H. lutescens Certainly not that species. It is pro- 

 bably the same as No. 169} or perhaps a variety oi Leskea 

 acuminata, Hedw. Sp. M. t. 56. 



176. a. popideutn. — If^ H. rejlexumhe considered a distinct 

 species, these specimens probably belong to that, having 

 broader leaves than ff. populeum. 



178. H. rutabulum This may be //. chrysostomum, 



Schwaegr. Suppl, I. ii. p. 276, but it is probably only a variety 

 of H. rutabulum. 



180. H. pulchrum — This is H. curvirostrum, Bridel, Br. 

 Univ. V. ii. p. 482. It has also been called H. Cooleyauum, 

 Torrey in lit.
