which equals ^ or ^ of the rest of the leaf, while those of the ' Bryol. 

 Europsea ' plant " n'ofFrent ordinairement qu'une pointe courte, 

 formee par le rapprochement des bords de la feuille." In habit the 

 two plants diiFer very considerably. 



There is still one doubt remaining, namely whether B. platyloma, 

 Schwgr., and B. ohconicum, Hornsch., be merely forms of one and 

 the same species. There is some difference in external aspect, and 

 the latter has the leaves scarcely marginated, paler and less rigid, 

 with a longer-necked, perfectly symmetrical and usually more pen- 

 dulous capsule.

(Descr. varietatis.) Planta gregariae. Folia fuscescentia, subpa- 

 tula, siccando appressa parum tortilia, elongato-obovata, apiculata, 

 nervo tenui excurrente cuspidata, concava, hand carinata, 2-3 cellu- 

 larum angustiorum seriebus marginata, apice denticulata. Flores 

 foeminei constricti, 6-8 folii. ' Flores masculi gemmiformes adfoeminei 

 basin nati, sessiles vel in innovationibus terminales (rarius in planta 

 propria) ; folia perigonialia sub-6, conniventia, exteriora ovato-acu- 

 minata, interiora minora, late-ovata, apiculata, antheridia numerosa 

 paraphysibus numerosis sublongioribus stipata, complectentia. Cap- 

 sula in pedunculo basin versus geniculato arcuatove subpendula, 

 elongato-pyriformis, fere clavata, e fusco purpurascens. Operculum 

 convexum, apiculatum, aurantiacum, nitens. Peristomium : externi 

 dentes pallidi ; internum membrana in processus carina valde pertusos 

 apice attenuates, ciliis 2-3-nis appendiculatis interjectis, fere ad me- 

 dium j&ssa. Annulus latus, compositus. Sporcd olivacese. 



The monoicous inflorescence is so constant a character in all the 

 individuals from the two localities above-cited, that 1 am led to sup- 

 pose this will prove a distinct species. In the typical form of B. tor- 

 quescens, from Jurangon and Cauterets, the fertile flowers are all 

 hermaphrodite, and quite turgid from the numerous antheridia they 

 enclose along with the archegonia. Yet a minute comparison of all 

 the other parts does not reveal any marked difference in the two 

 plants, and I prefer waiting for further evidence before I undertake 

 to decide on their being distinct or otherwise.
