C6G musci. (mosses.) 



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

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

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

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

 ico, Fendler. (Tab. 19.) 



Tribe XXXIII. HOOKERIEiE. 



78. HOOKERIA, Smith. (Tab. 19.) 



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

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

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

 late cilia, arising from a broad plicate membrane. Inflorescence monoecious. — 

 Large and handsome species, with an irregular sparse ramification, broad and 

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

 very loose areolation, formed 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 lias not been detected 

 on this continent, except in Oregon.) 



1. 13. aCMtafolia, Hook. 1 ? Grows on the ground, beneath dripping 

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

 Carolina. — Our specimens, as far as we are able to determine, (being without 

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

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



Tribe XXXIV. CLIMACIE^ 



79. CLIMACI II M , Web. & Mohr. ( Tab. 1 9. ) 



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

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

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

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

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

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

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



1. C. AMlcricsaMUin, 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 nearly 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. 19.) (Eu.) 



C. dendroides, Web. & 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, Oalces.
