all quite smooth. Perichaetial bracts pallid, larger, erect,

Hob. — Bathurst Harbour, West Coast, Rev. John 

 Bufton, No. 91 (Herb. Sir F. von Mueller), and track to Hartz 

 Mountains, No. 17. 



" A very distinct and beautiful species, at once dis- 

 tinguished from congeners by the branches being crowded 

 ■with branchlets." 



26. Hypnum (Bhynchostegium) moorei, Broth. Geh., n. sp. 

 Dioicous ; in dense, very broad, rigid tufts, bright or sordid 



green, somewhat shining. Stem elongate, vaguely branched ; 

 branches elongate, robust, terete, densely and squamosely 

 leaved. Leaves scariose, when wet erecto-patent, concave, 

 ovate, acute, margins erect, everywhere minutely serrulate ; 

 nerve from a wider base thinly vanishing above the middle ; 

 cells very narrowly linear, somewhat flexuous, chlorophyllose, 

 the basal shorter and wider, the alar indistinct. The internal 

 perichaetial bracts erect, somewhat reflexed at apex, from a 

 vaginant base narrowly acuminate, the margins remotely 

 serrulate at apex, loosely reticulate ; nerveless. Seta 

 17 mm. high, somewhat straight, red, everywhere 

 rough ; capsule subhorizontal, from a short neck ven- 

 tricose-oblong, pachydermous, pallid, smooth ; peristome 

 double, the outer teeth c. 0'66 mm. long and c. O08 mm. 

 wide, rufescent, hyaline at apex, scabrid ; the inner teeth 

 yellow, papillose ; the processes carinate, broadly perforate ; 

 the cilia in triplets, short, hyaline ; spores 0.012 — 0015 mm., 

 ochraceous, quite smooth ; operculum with au oblique beak 

 shorter than the capsule.

"A most distinct species, similar in habit to H. rusciformi, 

 Weiss, but sharply marked off from it by the rough seta." 



27. Stereodon nelsoni, Broth., n. sp. 



"Dioicous ; in somewhat loose tufts, bright green, when old 

 somewhat pallidly fuscous, shining. Stem firm, elongate, 

 flexuous, loosely leaved, pinnately branched ; the branches 

 patulous, short and simple, or longer, and with few branchlets, 

 distichously leaved. Leaves scariose, sparingly homomallous, 

 rather concave, patulous, ovate or oblong-ovate, shortly and 

 broadly acuminate, rather obtuse, margins erect, very 

 minutely serrulate, the apex finely serrulate ; two short
