    Although it is exceedingly probable that Kantia (=Ccdypogeia § B Raddi, Nees) is a marsupial form of Triyonanthece, it is difficult to fix on any one genus of that tribe of which it may be the direct descendant. Its nearest existing ally seems to be Bazzania (i.e. Mastiyohryum), and two species of Kantia are actually described and figured in Gottsche and Lindenberg’s monograph as Mastiaohrya, the one on tab. 2 as M. aUcrnifoliwn Nees, from Java and Nepal ; the other on tab. 3 as M- cellulosinn [=Jung. cellulosa Spreng.) from the West Indies. As I have myself gathered the latter in the Andes I can speak of it with confidence. Both species differ essentially from Mastiyohryum in the entire absence of a dichotomous ramification and of flagella, and agree with Kantia in every particular, especially in the presence of long stout cauline radicles —often clubbed at the end—such as are never seen in Mastiyohryum. No true species of the latter, indeed, shews any near approach to Kantia^ or any sign of an adherent (^much less of a pouched) involucre. Kantia agrees with Cephahzia in having all the branches, whether foliiferous or floriferous, postical, axillary to the underleaves; in the monandrous bracts and the 2-layered capsule. In aspect and leaf- structure it is very like some species of the section Alohiella; but the leaves are constantly incubous, while in Alohiella they are succubous, and only in Al. inteyrifolia, which has the leaves almost longitudinally inserted, is an incubous leaf very rarely interposed among normally succubous ones. The only genus of Triyonanthece which has an involucre partially adherent to the perianth is Anomoclada; and, in reality, when viewed from above, Anomoclada mucosa shows considerable external resemblance to Kantia, but differs essentially in having all the leafy and flowering branches antical, and only the rooting flagella postical, and in the suc- cubous leaves. In offering a resume of my speculations on this subject, I do not claim for it more than a j)rovisional importance. If, for the sake of com- Capenses: C. scanosa (Lehm.. Jungermnnia; Gymnomitrium sc. Syn. Hep.) C. renifolia (Mitt., Lindigina). Oceanicae et Australienses: C. squamata CTayl., Podanthe; Lethocolea Drmnmondii Mitt.) C. prostrata (Mitt., Lindigina).
