the sterile state ; the 2nd, 5th and 6th synonyms in Br. Moss-flora i, 100, 

 belonging lo the latter species. D. zonahtm is found on most of the higher 

 mountains of the Breadalbane range. 



DICRANUM TJNDULATUM Ehrh. 

 Figured on T. LXXXIV, B. 



Fine sterile specimens have been found in Dupplin woods and Woodhead 

 wood, Perth (/?. H. Meldmw 1891) ! ! It is best distinguished from D. Bonjeani 

 by the divergent leaves, having coarse sharp teeth standing out from the 

 margin, and both these have the leaf-cells shorter and not so narrow and 

 linear as in D. scoparinm. 



TORTULACEJE. 

 14.* MOLLIA BBEVIFOLIA (Scndtn.) Braithw. 



Dioicous ; densely tufted. Leaves dense, from a lanceolate base, 

 narrowly linear, obtuse. Caps, minute ovate; lid with a long very 

 slender beak. (T. LXXXIV, D.) 



SYN. Trichostomum brevifolinm SENDTN. in litt. C. MUELL. S>nops. i, 572 (1849). LIMPR. in 

 RABENH. U. kr. fl. Laubm. i, 575 (1888). 



Dioicous ; in densely cushioned tufts, fastigiate, dull green above, 

 brown at base, the stems very slender, dense-leaved. Leaves short, 

 from an erecto-patent base, slightly recurved, lanceolate, lineal and 

 narrowed above, obtuse at point, the margins incurved, nerve yellowish, 

 reaching apex or excurrent in an apiculus; cells at base minute 

 rectangular, yellowish and transparent, above rounded-quadrate, opake, 

 papillose on both sides. Perich. bracts sheathing, acuminate with a 

 projecting point, the cells thin rhombic smooth. Seta reddish below, 

 yellow above. Caps, very small, erect, ovate with a narrow mouth, 

 yellowish-brown ; lid long as capsule, with a long very slender beak ;

HAD. On rocks in limestone districts, rare. Fr. 6. 



Upwey near Weymouth (Mitten 1885)!! Near Swanage, Dorset (Mitten 1890), both 

 sterile. 



This has probably been mistaken for M. crispula, but differs in the leaf, 

 which is much shorter, and not boat-shaped at the apex.
