Leaves closely set, shortly 

 oblong lingulaLe, when dry 

 curled and incurved closely 

 towards the stem. 



Margin entire, crenulate, or 

 serrulate towards apex- 



Upper cells obscure with 

 strong papillye. 



Basal cells rectangular, with 

 several marginal rows of qua- 

 drate ones reaching to base. 



Capsule ovate , inch ned , 

 slightly curved and gibbous. 



Peristome deep purple red. 

 Teeth fairly regular ; dorsal 

 siirlace covered (except at 

 extreme tip)wilh vertical stria- 

 tions ; basal membrane broad, 

 of 4-8 articulations. 



Leaves looser, much longer, 



linear-lanceolate from a dis- 

 tinct base, tapering, when dry 

 flexuosc or twisted but still 

 spreading, not curled nor 

 incurved towards the stem- 

 Margin serrate, often strong- 

 ly, to the middle of the leaf or 

 below. 



Upper cells pellucid, light- 

 ly papillose only, or nearly 

 smooth. 



Basal cells elongated rectan- 

 gular, w^ith only one or two 

 rows of quadrate cells reaching 



to base.

diim, not only in habit and external features but also in structu- 

 Tal characters that wouhl seem to have considerable weight. The 

 long spreading leaves, retaining their position and only slightly 

 flexuose when dry give the plant a very distinct and striking 

 appearance, while it is of a much larger, looser grow^th, often 

 attaining 3-5 inches (3-12 cm.) in heiglil. This added to the leaf 

 structure, the erect, symmetrical capsule, and finally the very 

 dislinct peristome structure, wouki seem at first sight to give all 

 the requisites of a really good species. So I have regarded it until 

 recently ; but during the last tw^o or three years a number of speci- 

 mens have come under mv notice which have caused inc mate- 

 rially to alter my views.
