colour ; the fmitstalks are about 2 inches long. In the areola- 

 tion of its leaves it is intermediate between H. serpens and H. 

 varium, Beauv.

(Somalia, Brid.) 

 N. subrecta, sp. nov. Habitu N. trichomanoidis simillima, foliis 

 patentibus obovatis basi angustatis apice rotundatis crenulatis apiculo 

 brevi, nervo distineto ad f evanido, cellulis minoribus, perichaetialibus 

 ovatis acurainatis apicibus denticulatis, theca in pedunculo elongato 

 brevi ovali inclinata, operculo conico-acuminato, peristomio intemo 

 processibus perforatis ciliis brevibus rudiraentariis interpositis in 

 membrana fere ad dentium medium exserta. 

 Hab. Madeira, Santa Luzia Levada, about the roots of Thamnium alo- 



peeurum, Johnson. 

 Very closely resembling jV. triclwmanoides ; but its leaves are 

 scarcely at all curved, the nerve stouter and longer, and the lower 

 portions of the leaves narrowed, so that their figure is uniformly 

 obovate.

(Sciaromium.) 

 Caulis primarius repens, radicans ; rami erecti, inferne simplices, 

 superne pinnati pendulive prolixiqiie, ramosi. Folia rigida, 

 opaca, sublaevia, uninervia. Gellulce parvae, rotundatae. Phyl- 

 lidia nulla. Peristomium normale. 



L. spinosa, sp. nov. Caule primario repente radicante, ramis erectis 

 rigidis superne ramosis frondem stipitatem formantibus, foliis obscure 

 viridibus rigidis patentibus e basi ovata sensim longe subulatis, nervo 

 crasso concolore in apice evanido, marginibus apice parce remote den- 

 tatis alibi integerrimis, cellulis minutis rotundatis longitudine 2Wo» 

 latitudine 3 - Vo unciae circiter metientibus laevibus. 

 Hab. Madeira, Johnson and Mason ; Azores, Hunt, from Watson. 

 In all respects very similar to JSypnum hispidum, Hook. f. et 

 "Wils. Crypt. Antarct. t. 61, but more robust, and with leaves having 

 the nerve when closely examined not excurrent but vanishing in 

 the upper portion of the points, which too are dentate. The cells 

 are also rather smaller. 



Judging from the specimens, it would appear that well-deve- 

 loped stems would be from 4 to 6 inches high, and less curved than 

 is usual in H. hispidum. 



L. prolixa, sp. nov. Habitu L. spinosa sed graciliore mollioreque, 

 foliis patenti-erectis ovatis acuminatis leniter biplicatis, nervo lato 

 crasso sub apice evanido, marginibus superne indistincte serrulatis,
