construct^e, quoad marginem, a cellnlis geminis, sublagenaeformibus 

 et lenissime obliquis, ad basin connatis, ceterum tamen divergenti- 

 bus et in apice colli angiisti bullam minutam globosam et valde 

 incrassatam gerentibus." It is, however, to be noted that some 

 variation occurs in the structure of the margin of the lamella ; the 

 marginal cells may be only slightly elongated (fig. 13), or so elon- 

 gated as to be flask-shaped (fig. 12), and the lamella, sometimes for 

 a considerable distance, bears only a single row of marginal cells 

 (fig. 18 and fig. 11, left-hand lamella) instead of the geminate cells 

 described by Lindberg (figs. 11 and 12). 



(18). Anomodon Tocco^ Sulliv. & Lesq. 



In Muse. Bor. Amer. no. 240, which appeared in 1856, or a 

 little earlier, Sullivant and Lesquereux published (with a diagnosis) 

 a moss vmder the name of Anomodon ? Toccocb, from the locality "ad 

 rupes, prope Toccoa Falls, Georgise superioris, sterilis." In 1856 

 Sullivant (Muse. & Hepat. United States, 658 (58) ) gave a further 

 description of the plant, adding that perichfetia occurred, and 

 remarking as follows : — "In the herbarium of the late Dr. Taylor 

 are specimens marked " Neckera Nepalensis T. T. MSS., Nepal, appa- 

 rently the same as those from Toccoa Falls, with imperfect fruit, 

 like that of Anomodon attenuatus Hub." In 1864 A. Toccoa was 

 figured and described (with the same note) in Sulliv. Ic. Muse. 121, 

 tab. 76a. Up to the present time this single locality in Northern 

 Georgia is the only station known for the species in the United 

 States. 



In 1859 Mitten (Muse. Ind. Or. 127) published as a new species 

 of Anomodon from India and China his A. devulutus, with the follow- 

 ing diagnosis : — " Eamis pinnatim ramosis devolutis, foliis ovato- 

 lanceolatis apice acuminatis acutis dentatis nervo sub summum 

 apicem evanido. Hujus speciei fragmenta tantum vidi. Statura 

 coloreque plantas, A. viticuloso similis. Habitus, ob ramos circi- 

 natos devolutos, singularis." 



The authors of Bri/ologia Javanica (ii. 228), in enumerating 

 A, Toccoce Sulliv. & Lesq. from Java, Sumatra, and Celebes, add 

 "^. devolutus Mitt.?" In Hampe's herbarium, also, there occurs 

 a specimen labelled "^. Toccom SuU. & Lesq. Celebes. Lacoste," 

 on which Hampe has written " devohitus Mitt." 



With the above exceptions, all authors have considered A. 

 ToccocB Sulliv. &Lesq. and A. devolutus Mitt, as specifically distinct, 

 the plant from Georgia, U.S.A., and from Java, Sumatra, and 

 Celebes being referred to the former name, and the plant from 

 India, China, and Japan to the latter. Comparison of the example 

 of A. Toccom issued in Muse. Bor. Amer. no. 240, with Mitten's 

 type of A. devolutus shows conclusively, however, that the two are 

 identical. 



The fruit of the present species is stated by all authors to be 

 unknown, whereas in reality a good number of capsules are present 

 on the original Indian specimens of A. devolutus. In the United 

 States only perichsetia have been found ; the authors of Bnjolog. Jav. 

 describe the plantas being, in Java, Sumatra, and Celebes, "ubique
