DICRANACE.E.] 134 [Campylopns. 



3 strata of cells, two anterior larger and empty, posterior small and 

 chlorophyllose ; basal cells rectangular hyaline, becoming fuscous when 

 old, above these smaller and quadrate, becoming incrassate and 

 irregularly rhomboidal and oval toward apex. 

 HAB. Peaty soil in subalpine districts ; rare. 



With Dicranella heteromalla in Trickley planting, top of Whiteside hill, Wooler,

 (Barnes 1868)! ! Glencoe (Prof. Barker 1870). Morwell rocks near Tavistock, Devon

 Scout, Derby (Whitehead 1881) ! ! 



Close as this species stands to C flexuosus, it has so peculiar an aspect, 

 that we prefer to keep them separate, basing the distinction on the short 

 straight leaves of C. paradoxus, with t he lamina distinct to the apex. The 

 original specimens are scarcely an inch in height, and amongst the stems 

 are some with terminal rosettes of short ovate leaves more laxly areolate, 

 these are probably abortive males ; Whitehead's specimens are 2^ in. high, 

 and Wesley's nearly as tall. It is probable that it may eventually have to 

 sink to a Var. of C. flexuosus.

Dioicous ; laxly tufted, glossy yellowish-green above, dark brown or 

 blackish below, stems slender 3 10 in. high, dichotomous, with a few 

 radicles only at base. Leaves rather distant, longly lanceolate-subulate, 

 with large inflated auricles, very concave and subtubulose, serrated 

 toward apex, subula formed of the excurrent nerve, hispid at back ; 

 basal cells hexagono-rectang. empty, upper rhombic, chlorophyllose; 

 nerve half width of base, of 3 strata of cells, outer minute chlorophyllose, 

 middle equal hyaline, inner twice as large hyaline. Fruit aggregated, 

 about 4 together, perich. bracts oblong, convolute sheathing, suddenly 

 narrowed into a setaceous subula ; seta short flexuose, reddish brown, 

 cygneous when moist ; caps, suberect, pale brown, ovato-pyriform, 

 becoming cylindraceous when old, sulcate, annulus very broad, breaking 

 up, lid conico-rostellate, half length of capsule, per. erect, dark reddish- 

 brown, cleft above half way, the legs yellow, spores pale. 



Male plant slender, infl. 3 4 in a capitulum, gemmiform, outer 

 bracts ovate, subulate, inner ovate-oblong, muticous, nerveless.
