380 Dr. T. Taylor on five new species of Cryptogamic Plants, 



in eight to ten pairs, those at the top adpressed into a spike ; their 

 inferior margin incurved at the base. This species is strongly 

 allied to L. Nova-Hollandia (Schwaeg.), and may well be sup- 

 posed to belong to the same genus even in the absence of fruc- 

 tification. It may be distinguished by its far smaller size, its 

 more obtuse leaves, and by their shorter nerve. In one instance 

 the stem is prolonged at the top into a flagelliform shoot, de- 

 stitute of all but minute rudimentary leaves. 



Phragmicoma, Dumort. 



1. P. affixa (Tayl.); caule debili repente vage ramoso seu subdi- 

 chotomo, foliis laxe irabricatis erecto-patentibus oblongo-rotun- 

 datis margine subundulatis apice parce denticulatis lobulo minuto 



' vel subnullo, stipulis rotundatis integerrimis, calyce demum axillari 

 oblongo-obcordato compresso ore integerrimo. 



On Dancea alata (Sm.), Jamaica. In Dr. R. K. Greville's Herbarium. 



Five or six lines long ; very pale olive, nearly whitish : a 

 female flower and a branch issuing from near the top of the 

 past year's shoot. Leaves flaccid, often entire, sometimes with 

 three or four obtuse teeth ; the perichsetial erect, oblong, sub- 

 dentate. Capsule pale, splitting half-way down ; its valves 

 broadly ovate. The leaves by no means imbricated, flaccid, ir- 

 regular in outline, variously twisted : the indistinct lobules and 

 the large cells serve to keep the present distinct from all de- 

 scribed species. 



Radula, Nees. 



1. R. Grevilleana (Tayl.) ; caule implexo repente subpinnato, ramis 



patentibus, foliis imbricatis erecto-patentibus integerrimis lobo 



superiori obovato-rotundato, inferiori minuto trapezoideo, calyce 



demum axillari elongato ovato-oblongo apice compresso truncato, 



basi angustato pedicelliformi, perigoniis minutis linearibus ra- 



morum fere ad apices usque productis lobulo monandro. 



On Danaa alata (Sm.), Jamaica. In Dr. R. K. Greville's Herbarium. 



Very minute, three to four lines long, olive-coloured, closely 



adhering to the subjacent fern; a calyx and an innovating 



branch terminating the preceding year's shoot. Leaves touching, 



more patent than erect ; the perichsetial broadly elliptical, short. 



Capsule linear, very narrow. Perigonia on short lateral branches 



with ten or twelve pairs of minute imbricated ventricose leaves, each 



containing a spherical anther. The exserted part of the pedicel 



about as long as the calyx ; this is on a narrow pedicel or nearly 



cylindrical opake base contained within the perichsetium ; it is 



nearly as long as the shoots. This species differs from R. bucci- 



nifera (Tayl.) by the smaller size, more imbricated leaves, whose 



tops are not so rounded, and by the calyx bulging at the base, 



and so by no means obconical.
