Supplement.] 241 



A further study of this plant and of the fine specimens collected by Mr. Cocks, 

 as well as the excellent descriptions of Husnot and Dixon, have satisfied me that 

 it should stand as a species. The plant from Shanklin should be referred to 

 P.fontana var. pumila (Turner), to which probably Lindberg's var. parvula also 

 belongs. It approximates much nearer to the type, being only smaller in all its 

 parts. 



PHILONOTIS FONTANA (Z.) Brid. 



Var. ampliretis Dixon in Journ. Bot. 1902, p. 71. 



Tufts' very lax, light green; stem thin, weak, with a few smooth radicles, 

 simple or divided, sometimes with deciduous axillary shoots in the upper part of 

 stem. Leaves very lax, patent, not decurrent, lanceolate, acutely pointed, not 

 plicate, plane at margin and with short teeth, nerve very thin, ending in or below 

 the point ; all the cells lux, thin-walled and chlorophyllose. Sterile.

Mr. Dixon has clearly traced this up to the polymorphous /'.^«/a«a, although 

 it differs considerably in appearance. Venturi had already named another variety 

 laxa. 



MNIUM LYCOPODIOIDES (Hook.) Schwaeg. 



Dioicous ; near M. orthorhynchum, but in looser tufts. Leaves dark 

 green, decurrent, distant, upper narrow at base, elongated, Ungulate, margin 

 limbate, with pairs of acute teeth ; capsule horizontal, subcylindraceous 

 slightly curved ; lid rostrate. (T. CXXVIII, A.)

Dioicous ; very near M. orthorhynchum, but with more distant, narrower,, 

 and longer leaves, with laxer areolation. Plants tall and slender, the 

 leaves distant, lower oblong, almost entire, upper gradually elongate- 

 Ungulate, erecto-patent, decurrent, acutely pointed, bordered by 2 rows 

 of rufous incrassate cells, and pairs of acute teeth ; cells larger than in 

 M. orthorhynchum, nerve red, sharply toothed at back above, and excurrent,.
