666 (66) Musci. (mosses.) 



trate, rooting copiously from the under side ; leaves dark-green, somewhat close, 

 serrulate at the apex ; costa extending more than half-way ; capsule cylindri- 

 cal ; ciliolaj of the inner peristome long ; operculum conic, shortly rostrate. — 

 On the roots of ti-ees, San Antonio, Texas, Wright : also Santa Fe, New Mex- 

 ico, Fendler. (Tab. V.) 



Tribe XXXm. HOOKEEIE^. 



T8. HOOKERIA, Smith. (Tab. V.) 



Calyptra conic-mitriform, shortly lobed at the base. Opercultun conic-rostrate. 

 Capsule oval, hoiizontal, pedicellate. Peristome double ; the exterior 16 linear- 

 lanceolate and closely articulated teeth; the interior 16 caiinate lanceolate-subu- 

 late cUia, arising from a broad pUcate membrane. Inflorescence moncecious. — 

 Large and handsome species, with an in-egular sparse ramification, broad and 

 flat stems and branches, and complanate shining membranaceous leaves, of a 

 very loose areolation, foimed by large oval-hexagonal hyaline cellules. — (Named 

 after Sir Wm. J. Hooker.) — (Tab. V. contains a figure of the type of the genus, 

 Hookeria lucens, with ecostate and obtuse leaves, which has not been detected 

 on this continent, except in Oregon.) 



1 . H. acutifolia, Hook. 1 Grows on the ground, beneath dripping 

 rocks, Southern Ohio, and Alleghany Mountains, in Pennsylvania and North 

 Carohna. — Our specimens, as far as we are able to detennine, (being without 

 fruit,) agree well with H. acutifolia, Hoolc, an East-Indian species, which appears 

 to differ from H. lucens, Smith, only in its acute leaves. 



Tkibe XXXIV. CLIMACIE^. 



79. ClilMACItJM, Web. &Mohr. (Tab. V.) 



Calyptra dimidiate, somewhat twisted, long, embracing the top of the pedicel. 

 Operculum conic-rostellate. Capsule oval-oblong or cylindrical, erect, long-ped- 

 icelled. Peristome double ; the exterior 16 linear-lanceolate, closely articulated 

 teeth; the interior 16 linear-lanceolate, carinate, lacunose cilia, connected at the 

 base by a veiy narrow membrane. Columella emergent. Inflorescence dioe- 

 cious. — Large and striking Mosses, of a tree-like aspect. — (Name from /cXt/xa- 

 KLov, a little ladder, from the appearance of the cilia of the inner peristome.) 



1. C. Americanum, Brid. Main stems rhizoma-like, subterraneous; 

 primary branches erect (2|-'-3' high), below simple, furnished with small and 

 appressed scale-like leaves, above fasciculately branched ; leaves ovate-lanceolate, 

 auriculate at the base, concave, plicate, costate neai-ly to the apex, serrate above, 

 with a minute elliptical areolation ; capsule cylindrical. — On the ground, or on 

 very much decayed logs, in moist shady woods. (Tab. V.) (Eu.) 



C DENDEOIDES, "Wcb. & Mohr., (common in Europe,) with a shorter and 

 oval-oblong capsule, obtuse branchlets, and leaves not dilated at the base, occurs 

 in British America, Drummond; and probably on the White Mountains, New 

 Hampshire, Oakes.
