dined, curved ; segments cleft between the articulations ; cilia 

 three, as long as the segments ; membrane large, as in the last 

 species. — Journ, Linn. Soc. viii. 31, t. 5. 



Hab. Pend d'Oreille River, N. Idaho {Lyall) ; Fort Colville ( Watson). 



From the author's remarks this species has the same appearance as the 

 last, from which it is distinguished by the apical leaves of the lateral 

 branches having their points broad, somewhat acutate, and obtuse. Tlie 

 peristome is more complete, the segments being separated by three long 

 cilia. 



29. H. Nuttallii, Wils. Widely cespitose, yellowish brown ; 

 stems prostrate, radiculose ; branchlets crowded, spreading or 

 homomallous : leaves closely imbricate, narrowly oblong-lanceo- 

 late, gradually acuminate, plicate-striate, coarsely dentate at the 

 recurved base, serrate above ; costa vanishing in the apex ; 

 inner perichaetial leaves erect, long-lanceolate, narrowed into a 

 filiform i^oint, striate : capsule long-cylindrical, suberect and 

 subarcuate, with a short distinct neck ; pedicel very short and 

 rough, scarcely as long as the capsule ; operculum conical, short- 

 rostrate ; segments split their whole length ; cilia very short, 

 rudimentary ; annulus narrow. — Bryol. Brit. 334, 339 ; Sulliv.

 Schimp. Bryol. Eur. Camptothecixtm, 6. Leshea Californica,

Hab. On trees. Western coast of North America (Menzies); Cali- 

 fornia, Oregon, etc. [Bolander, Bauer, Nuttall, Bigelow, etc.); N. Idaho 

 ( Watson); not common. 



Easily recognized from its congeners by its long thick capsule, short 

 pedicel, shorter rostrate operculum, the densely pinnate ramification, and 

 the dentate base of the leaves. 



30. H. Nevadense, Lesq. Plants robust, loosely cespitose, 

 yellowish green ; stems cree2ung ; branchlets short and hori- 

 zontal, or longer, irregularly divided and arcuate : leaves secund, 

 lanceolate, gradually short-acuminate, minutely serrate at the 

 apex, carinate by the costa, deeply biplicate ; borders revolute 

 or recurved ; alar cells very few, irregularly quadrate : capsule 

 erect or subcernuous, cylindrical-ovate, on a short reddish pedi- 

 cel; operculum long-rostrate; cilia very short and rudimentary 

 or none ; annulus compound. — Mem. Calif. Acad. i. 33. 



Hab. On rocks in the spray of Nevada and Bridal Veil Falls, Yose- 

 mite Valley (Bolander); Spokan Falls (Watson). 



Distinguished from II. lutescens by its yellowish green color, the large 

 thick stems and branches, its distinctly pinnate ramification, the alar
