82 MUSCI-PLEUROCARPI-PERISTOMI. [Hypnum. 



The plant varies much in size. Hedwig's H. plumosum (our H. sale- 

 brosum) has striated leaves and ranks near H. lutescens. 



23. H. pidchellum, Dicks, {elegant Feather -Moss) ; leaves 

 loosely imbricated the upper ones subsecund all of them lanceo- 

 lato-acuminate entire nerveless, capsule ovato-cylindrical nearly 

 erect, lid conical. Dicks. Cr. Fasc. 2. t. 5.f. 6. Turn. Muse.

Woods, in alpine countries and among rocks. Fr. Sept. — A small 

 species, scarcely an inch in length ; the leaves spreading out nearly 

 horizontally on two opposite sides of the stem, whence Wahlenberg has 

 referred it to his division " shoots plane ," but its upper leaves are sub- 

 secund and it approaches in many respects the H. Silesianum. 



-\ — s- Leaves striated. 



24. H. rufescens, Dicks, (red mountain Feather-Moss); leaves 

 erecto-patent lanceolate acuminate entire striated faintly two- 

 nerved at the base, capsule ovate nearly erect, lid conical. Dicks.

Scottish mountains, among moist rocks, not unfrequent. Fr. rare, 

 July. — i n this state the Rev. Colin Smith finds it abundantly near Inve- 

 rary : and Mr. Wilson at the upper end of Finlarig Burn, Perthshire. 

 — Whole plant of a singularly yellowish-purple colour ; stems erect. It 

 varies in size, and small decumbent specimens considerably resemble the 

 Hypnum incur vatum of authors. 



25. H. polydnthos, (many-fruited Feather-Moss); leaves 

 erecto-patent ovato -lanceolate remarkably acuminate minutely 

 serrated at the point smooth obscurely 2-nerved at the base, 

 capsule ovato-cylindrical erect, lid conico-acuminate. Hook, in

Trees and rocks, perhaps not rare : first found in England on Apple 

 trees, near Darlington, by Mr. W. Backhouse ; and on rocks and trees 



about Forfar, Scotland, by Mr. Drummond. Fr. .—Stems forming 



densely entangled tufts, with numerous short erect branches. Leaves 

 erecto-patent, slightly secund on the lowermost creeping shoots, ovato- 

 lanceolate, running out into a long narrow acumen, which appears under 

 a magnifier slightly serrated ; there are 2 very short indistinct nerves at 

 the base. Seta about half an inch long. Capsule cylindrical, slightly 

 swelling at the base, reddish-brown. A small var. of H. capressiforme, 

 not unfrequent upon trees, has often been taken for this plant and \» in- 

 deed figured as such in E. Bot. 1. 1664. Our plant is known by the leaves 

 pointing in all directions, broader below, more suddenly acuminated 

 above, the capsule quite erect, and by having decidedly the peristome of 

 a Leskea.
