666 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 ; cilioke 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. MOCKERIES. 



78. IIOOKERI4, Smith. (Tab. 19.) 



Calyptra conic-mitriform, shortly lobcd 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, 

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

 on this continent, except in Oregon.) 



1. H. aciitifolia, Hook.? 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. 



TKIBE XXXIV. CLIMACIE^E 



79. CLOIACIUJW, Web. &Mohr. (Tab. 19.) 



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 very narrow membrane. Columella emergent. Inflorescence dioe- 

 cious. Large and striking Mosses, of a tree-like aspect. (Name from K\ifj,d- 

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



1. C. Amcricfftlllim, Brid. Main stems rhi/oma-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, Oakes.
