9 Ceplialozia. 



ogenous female flowers are bilobed and usually laxly reticulate as in 

 EucepJudozia ; wliile the trigonous perianth, the form and number of the 

 pistiUidia, the calyptra, and the capsule in two layers, whereof the 

 inner are strengthened by semiannular fibres, are all exactly on the 

 same type. In his ' Mexikanske Levermosser,' Gottsche admits a Sphag- 

 noecetis with leaves emarginate or 2 — 3 dentate at the apex; but, indeed, 

 in our own Odontoschisma Sphagni retuse or indented leaves are often met 

 with ; and Mr. Stabler has gathered on Fowlshaw Moss, Westmorland, 

 a form in which emarginate leaves decidedly predominate. 



Again, Eucephalozia Francisci (Hook.) is almost a miniature copy of 

 Odontoschisma denudatum, in the numerous flagella, the suborbicular 

 leaves, the female involucre and perianth, the reddish gemm^ borne on 

 the apex of attenuated branches, &c.; and only the slight, but distinct 

 and constant, apical notch of the leaves of C. Francisci is quite wanting 

 to 0. denudatum, or is seen rarely on slender sterile branches. 



On the bark of trees inundated by the river Casiquiari, in South 

 America, I gathered a small Cej^halozia (C obcordata n. sp.) with leaves 

 no larger than those of C. Francisci, but flatter, and obcordato-orbicular 

 in outline ; in its habit so like small Ceplialozia Sphagni that I took it for 

 a form of that species, until examination shewed essential differences in 

 the absence of flagella, the shape of the leaves, and the monoicous in- 

 florescence : the $ flower mostly springing from the side of a c^ spike, 

 as is sometimes seen in C. bicuspidata, C. pygmcea n. sp. and other 

 species. In the sum of its characters, it is exactly a link between Odonto- 

 schisma and Eucephalozia. 



From Odontoschisma to Lembidiubi is but a step, without any break. 

 This is a name applied by Miiiten to a small group from the southern 

 hemisphere — chiefly from the oceanic islands — of which the earliest 

 known species, Jung, nutans Tayl. (1844) stood for some time in Masti- 

 gohryum (Cf. Hook. f. et Tayl. Fl. Antarct. and Lindenb. et G. Sjjec. 

 Hepat.) — a genus from which it is remote enough, having neither the 

 dichotomous branching nor the narrow falcate leaves (truncate, and 

 normally 2 — 3 dentate at the apex) common to all true Mastygohrya. 



The habit of Lemhidium is very much that of 0. denudatum, but the 

 leaves are mostly much denser and nearly transverse — in L. nutans, in- 

 deed, occasionally subincubous — cochleato-or-cymbiformi-concave, and
