Trematodon vulgaris BRID. Bry. univ. i, 386 (1826). 



Autoicous ; in small dense tufts, pale green or fuscescent ; stems 

 short, branched, radiculose at base. Leaves erecto-patent. flexuose, from 

 a concave ovate-oblong base, suddenly lanceolate-subulate, canaliculate, 

 entire ; nerve semiterete, excurrent in the subula, cells at base narrow 

 rectangular, above rhombic or hexagonal ; perich. bracts much larger, 

 elongate-oblong, gradually acuminate, laxly areolate at base. Caps, on 

 a long flexuose straw-coloured seta, oblong, straw-coloured or orange- 

 brown, the neck cylindric, long as capsule, subarcuate, tumidly stru- 

 mose, the base abrupt at the inner side ; annulus broad, lid conic, 

 subulate rostrate ; teeth confluent at base on an exserted membrane, 

 cleft into two unequal legs, or perforated in the middle line, red, 

 incurved when dry. Male infl. terminal on a basal branch, bracts 

 small, ovate convolute, acuminate, nearly nerveless. 



HAD. Bare wet turfy places in subalpine districts ; very rare. Fr. 7 8. 



In a path at base of Schiehallion, near Tummel bridge, Perthshire (Braithwaite and 

 Crombie, 1883) ! ! 



The species of this beautiful genus are remarkable for the long neck to 

 the capsule which gives the fruit a peculiar club-shaped appearance. Only 

 a single tuft was found, and that was growing in the centre of a patch of the 

 rosy red form of Byy um pattens. The genus Bruchia also belongs to this sub- 

 family.
