6. DlCRANUM SCOPARIUM, HedlV. 



Dicranum scoparium, Hedw. Sp. Muse. p. 126 ; Bryol. Europ. 1, Dicran. Monog. 

 p. 34, t. 26 and 27. 



Hab. Oregon. 



7. Dicranum Sandwicense, Sp. Nov. (Tab. 1.) 



D. procerum flagelliferum ; foliis late lineari-lanceolatis obtusiuscidis 

 apice serratis, costa tenui perciwsis, areolatione sinuoso-lineari, peri- 

 chcetialibus permagnis ; capsula cylindracea suberecta Icevi aciculari- 

 operculata. 



Var. /3. condensatum : caidibus abbreviatis robustis, foliis confertis. 

 Var. y. elongatum : caulibus elongatis, foliis dissitis patentissimis. 



Hab. Sandwich Islands, Kaala Mountains, Oaku; var. ,2, Mauna 

 Kea, Hawaii ; var. r, banks of the crater, East Maui. 



One of the largest species of the genus. Stems stout, 5-6 inches 

 high (in var. p, 1-2 inches ; in var. r, 10-12 inches), sparingly 

 divided, producing from their apices slender upright flagellse as in D. 

 flagellare. Leaves spreading on all sides from a semi-amplexicaul 

 oblong base, broad linear-lanceolate, somewhat obtuse, more or less 

 canaliculate, strongly serrate above, with a slender percurrent costa 

 which is dentate on its back near the apex; areolation of sinuous- 

 linear cellules : perichsetial leaves very large and conspicuous, convo- 

 lute, their points short and serrate, costa variable. Capsule cylin- 

 drical, nearly erect or erecto-cernuous, smooth when dry and empty : 

 operculum with a long erect subulate rostrum. Male buds found only 

 among the tomentose radicles of the fertile stems. 



A very distinct species. May possibly be Montagne's D. strepto- 

 phyllum, so named from the leaves being " spiraliter pluries tortis" a 

 character which our specimens do not exhibit.
