PHILONOTIS. 20,1 



70. PHILONOTIS Brid. 



Plants variable in size, often tall, stems with fasciculate 

 branches, producing whorled innovations below the inflorescence ; 

 densely radiculose below. Leaves short ; in the dioicous species 

 often of two forms, those on the stem of the male plant more 

 distant, appressed, less acuminate ; cells usually papillose. 

 Capsule cernuous, smooth or striate. Inner peristome with the 

 cilia well developed. Paludal mosses, for the most part. 



A rather large and very natural genus, differing from 

 Bartramia, as regards our species, in the short, oval or lanceolate 

 leaves, the whorled branching, the discoid male flowers (in the 

 dioicous species), and the cilia of the inner peristome. The 

 dioicous species are widely distributed and very variable, and 

 consequently present great difficulties to the systematise

 dimorphous. Synoicous or autoicous. Male flower gemmiform. 



1. Philonotis Wilsoni Braithw. (Bartramidula Wilsoni 

 B. & S., Schp. Syn.) (Tab. XL. H.). 



Minute, slender, about |-inch high, pale green, in small loose 

 tufts. Stems procumbent at base, branched in whorls from below 

 the flowers. Leaves small, ovate-lanceolate , more or less 

 acuminate, denticulate above, with plane margin ; cells at base 

 lax, rectangular, gradually narrowing above, at apex linear,
