DicRANACE^.] 130 [Campyloptis. 



Dioicous ; in very dense compact tufts interwoven with rufous 

 tomentum, fastigiate, i — 3 in. high. Stems slender, cuspidate, light 

 silky green above, fuscous below, dichotomous, with alternate innova- 

 tions which are easily detached. Leaves appressed when dry, erecto- 

 patent, straight, rigid, narrowly lanceolate-subulate, with a few small 

 teeth at extreme apex, channelled in the lower part, becoming tubulose 

 above from the incurved wings ; nerve very broad, | width of base, of 

 3 — 4 strata of cells, anterior lax and hyaline, posterior turgid and 

 prominent ; cells at extreme base brown and vesicular, above hyaline, 

 very narrow at margin, elongato-rectangular towards nerve, the upper 

 small and elliptic. Perich. bracts sheathing, suddenly narrowed into a 

 long subula ; caps, pale, ovate, striate, annulus broad, lid half length of 

 caps, beaked, peristome small, the teeth cleft to middle ; spores large. 



Hab. — Highland mountains, on the ground and wet rocks ; not common.

A pretty species, readily known by its very compact tufts, closely 

 interwoven with fine branched radicles, which principally arise from the cells 

 at back of the nerve. The fruit has only been found by Breidler on the 

 Venediger near Zell-am-see. 



4. CAMPYLOPUS SUBULATTJS Schimp. 

 Dioicous; dwarf, densely gregarious, eradiculose ; leaves short 

 erect, lanceolate-subulate, nearly entire at apex, nerve half width of 

 base, of 4 cell-layers. (T. XVIII, B.)

Dioicous ; densely gregarious, yellow green above, fuscescent 

 below, stem ^ in. high, not radiculose, simple or dichotomous, with 

 caducous ramuli. Leaves enlarging upward, erect short rigid, 

 lanceolate-subulate, deeply concave, not auricled, entire or with a few 

 teeth at extreme apex, which is also sometimes hyaline ; nerve very 

 broad, ending with the apex, of 4 strata of cells, the two anterior larger 

 and empty, two posterior smaller, the innermost of these least and 

 chlorophyllose ; cells at base lax, thin, very narrow at margin, rectan- 

 gular toward nerve, upper small rhombic or straight. Seta straight. 

 Hab. — Dry sandy or gravelly banks by roadsides ; rare.
