distinct but inconspicuous, small groupof brownish, obscure, elongate, 

 elliptic or sinuous cells with very incrassate walls. 



The plant is certainly no Rhaphidostegium, but of Amblystegioid 

 affinity, and 1 think it is almost certainly to be referred to the genus 

 Drepanocladus, near D. scorpioides, or perhaps still nearer to 

 D. trifarius (W. & M.). 1 think it should stand as follows: — 

 DltEPANOCLADUS SECUNDIb'OLlUS (C. M.) Dixon comb, now 

 Iljlj)in(ii) secundifolium C. M. Syn. ii. 343 (Ls">l). 

 Semalophyllum secundifolium .Mitt, in Journ. Linn. Soc, Bot. 



xii. 481 (ISO!)). 

 Bhaphidostegium secundifolium Jaeg. Adumbr. ii. 392. 

 Hypnmn lithophilum Hook. f. & W., Fl. Antarct. ii. 120 (non 

 Hornsch.). 



Neckera glossophylla Mitt. 



Mitten described this in Musci Ind. Or. (Journ. Linn. Soc., Bot. 

 vol. iii. Suppl. p. 119 [1859]), from specimens gathered in Sikkiro by 

 Hooker, and in the Khasian Hills by Hooker and Thomson. He 

 compares it with N. flabellata, with which, however, it has no great 

 affinity, though in habit resembling it. Fleischer in Hedwig. xlv. 78, 

 places it in his new genus Somaliodendron, next to II. microdendron 

 (Mont.) Fleisch., from Cochin China. 



In Beseherelle's herbarium there are original specimens of II. 

 microdendron of Gaudichaud's gathering from Cochin China, which 

 I have compared with the Indian plants and find them identical. 

 The habit varies, as it does in most of the species of Somaliodendron, 

 being sometimes loosely pinnate with the branches sparingly re- 

 branched, and at others densely bipinnate. But these variations are 

 in no way associated with any geographical distribution. Neckera 

 qlossophylla must therefore fall under the synonymy of Somalio- 

 dendron microdendron (Mont.) Fleisch. 



PlNNATELLA ELEGANTISSIMA (Mitt.) Fleisch. 



Mitten describes Porotricliam elegantissimum from Tutuila, 

 Samoa, in Journ. Linn. Soc, Bot. x. 187 (1868). He compares it 

 with Neckera anacampiolepis C. M., but with the leaves not undu- 

 late. Original specimens sent me from the New York Bot. Garden 

 struck me as closely resembling Pinnatella Kuhliana ( Bry. jav.) 

 Fleisch., and on comparing them with the plant of Bry. javanica, 1 

 found them identical. Fleischer, it is true (Hedwig. xlv. SI) places 

 the two in different sections, thus : — 



" (a) Laubbl. oben stumpffich abgerundet, 



zuweilen mit aufgesetzen Spitzchen. P. Kuhliana. 

 (b) Laubbl. mehr. allmaehlich zuge- 



spitzt P. cleganlissinia." 



This difference is, however, purely imaginary. The leaf apex in 

 Mitten's type of P. elegantissima is precisely as figured in Bryol. 

 javanica for P. Kuhliana. 



Brotherus also places the two plants in slightly differing Sections, 

 thus : — ■ 



" Aeste vei'llacht P. elegantissima. 



Aeste nicht oder kaum verllacht P. Kit It liana.'"
