OF THE GENUS SYMBLEPHARIS. 495 
so that it is evident Hampe’s description, * seta erecta,” applied 
to the dry state only. 
The capsules of the type specimens of S. Lindigii are cer- 
tainly more cylindrical than in the Bolivian ones, but a few 
capsules occur which are oblong. ‘The teeth of S. Lindigii 
are very fragile, and are so strongly incurved when wet, that 
it is difficult to see how much the apex of each tooth is divided. 
The peristomes are mostly imperfect in the ripe capsules of 
the type of S. Lindigii, but some show teeth bifid to the middle. 
Müller (9) describes his peristome teeth as “ usque ad medium 
fissi" but I have noticed several teeth quite entire in Mandon's 
specimen, uo. 1656, from which fig. 33 was drawn. 
In S. helicophylla, Mont., the peristome teeth are very variable 
in this respect; entire and bifid teeth commonly occur in the 
same peristome (PI. 25. fig. 7).

xii. (1869) p. 49; Jaegr. Adumbr. i. p. 74 (1897). 
DisruiBUTION.—S. America: Ecuador, Andes of Quito, near 
Mulmul and Tunguragua, 9000 ft. (Spruce, no. 23, and Jameson). 
S. fragilis, Mitt., differs in its rigid habit from all other species 
of the genus. In Mitten's description there is no mention 
‘made of the structure of the leaves, which is quite different from 
that of the other species. The leaves are very fragile, i. e. brittle 
through their rigidity, so that they are usually broken across 
above, and are bistratose in the upper part (Pl. 26. fig. 30). The 
transition from the unistratose structure of the lower part (PI. 26. 
fig. 29) to this takes place just above the wings of the vaginant 
base. The two *' stereid-bands," which take a prominent part 1n 
the nerve-structure of the lea!-base, gradually disappear as the 
apex is reached. The leaf-cells are quadrate to shortly rect- 
angular, not “ rotundatus " as described. The peristome teeth 
(not deseribed by Mitten) are more or less bifid, sometimes to 
the middle, and often irregularly perforated, and are not arranged 
in pairs. The inflorescence is autoicous.
