MR. W. mitten's list OF SAMOAN MOSSES. 171 



Musci Archip, Ind. t. 48? et Bryol. Javan, t. 202, var. tenue.— M. 

 Vitianum, Sull. Amer, ExpL Exped, p. 22, t. 21 ?) 

 Hab. Tutuila, on trees in a damp place (1000-1500 ft.). No. 4. 



Meteorium Vitianum is probably identical witli this species ; 

 for, notwitlistanding Sullivant's remark that in Aerobryum Ion- 

 gissimum there are no papillse, I find them present in authentic 

 specimens of that Moss as well as in the Samoan specimens ; and 

 they in each arise from the middle of the cell. 



The specific name '^ longissimum " "was applied by Eaddi to a 

 Brazilian Moss wliich may prove to be referable to this genus, 

 having the calyptra cucuUatc and not mitriform as in Meteo- 

 rittm. 



The rarity of the fruit in these mosses renders the certain 

 identification of species very difficult. 



In Mr. PowelPs specimens the young calyptra is elongate, as 



in A, s^eciosum, 



Meteorium intricatum^ sp. n. Dloicum; rami graeiles, elongati, 

 flexuosi, ramulis divcrgentibus curvatis laxe pinnatim raraosi ; foHa 

 ramea undique erecto-patentiaj torta, a basi cordata, auriculis crenatis, 

 ovato-lanceolata, sensim acuminata, integerrima, nervo obsoleto, eel- 

 lulis angustis elongatis brevissime obseureque pluripapillatis ; folia 

 ramulina superne latiora, haud acuminata, subscnnilata, semitorta, me- 

 dio inferne canaliculata, nervo tenui infra medium obsoleto ; folia pe* 

 richjctialia patentia, longe acuminata; vaginula filis exsertis barbata; 

 pedunculus crassiusculus, sublaivis, foliis perichfctialibus subduplolon- 



gior, curvatus ; theca oblongo-cylindracea, innequalis, operculo subu- 

 lato ; peristomium dentibus elongatis irregularibus nonnullis inter se 

 cohaereutibus fissisve obscuris, internum processibus angustis obscuris 

 brevioribus, membrana basilari carens ; calyj)tra infcrnc i)ilis j)aucis 

 barbata. Flos masculus parvus, gemmiformis, antheridia 8-10, para- 



physibus paucis immixta fovens. 

 Hab. Tutuila, on living trees in the shady forests (20-1000 ft.). No. 5. 

 Also in the Fisji Islands, Seemann, 



an 



length, foliage green, dark brown in age. In size, colour, and 

 habit, this species agrees with M. helictopliyUum, Mont. {C?^- 

 ]yh(ea)^ from Tahiti ; but its longer capsule is exserted, and thus 

 it comes nearer to M.Jlorihmidum, Dozy et Molk. Muse. Archip. 

 Ind. t. 53 ; but it differs from this in the cordate-auriculate base 

 of its leaves, and also in the teeth of the external peristome not 

 being united on a base that is exserted above the mouth of the 

 capsule. 



M. ^KUGiNosuM, sp. n. Dioieum; rami elongati, gracillimi, flexuosi.
