39^ HYPXACE/E. 



The male plant of this moss is extremely slender, and very unlike the fertile ; 

 this is quite distinct in its habit, from its crowded, erect branches, very silky and 

 glossy, especially when dry. The strongly plicate leaves and long nerve easily 

 separate it from all allied plants except the two species of Camptothecium and, 

 ■perhaps, Brachythecium glareosum ; and its creeping stems with crowded erect 

 branches, and very silky gloss, distinguish it from any of these. The fruit is not 

 unfrequently produced, and then usually in great quantity. The leaves are more 

 appressed when dry than in most of the allied species, and it is their pale glossy under 

 side that gives the dry plant its peculiar, silky character. The difference in habitat 

 must also be remembered, when comparison is made with the above-mentioned 

 ■species. 



109. OAMPTOTHEOIUM B. & S. 



Stems erect or prostrate, irregularly branched. Leaves 

 lanceolate-acuminate, single-nerved, deeply plicate ; cells narrow- 

 linear almost to base, wider and quadrate-rectangular at angles. 

 Seta smooth or rough. Capsule more or less inclined, curved, 

 ■oblong-cylindric ; lid conical-rostellate. Processes of inner 

 peristome well developed. Dioicous. 



A well defined genus, differing from Pleuropus in the 

 inclined, curved capsule ; from Brachythecium in the narrow- 

 linear, not rhomboid areolation, almost uniform to base except at 

 "the angles. 



/Stem scarcely radiculose ; seta rough i. lutescens 



\ Stem copiously tomentose; seta smooth 2. nitens 



1. Camptothecium lutescens B. & S. (Hypnum lutescens 

 Huds.) (Tab. LII. D.). 



Stems tufted, in irregular patches, ascending, with irregular 

 or somewhat pinnate erect branches ; shining, golden green, 

 brown below. Stems hardly radiculose, about 2-4 inches long. 

 Leaves crowded, erecto-patent, erect but not appressed when dry, 

 glossy, deeply plicate, resembling those of Pleuropus sericeus 

 but rather larger, i—i l /i lines long, both margins usually recurved, 

 basal auricles somewhat less distinct, hardly toothed ; areolation 

 similar, but the basal ones more incrassate, with the cell-walls 

 ■distinctly porose. Pericha^tial bracts longly acuminate, sharply 

 toothed at the base of the acumen. Seta rough. Capsule inclined 

 or almost erect, slightly curved, narrowly oblong or sub-cylindric, 

 .somewhat contracted below the mouth, orange-brown ; lid acutely 

 conical, narrow. Peristome small, yellowish. 



Hab. Dry hedgebanks, quarries, etc., principally in calcareous districts. 

 Frequent.
