420 HYPNACE/E. 



Hab. Stony ground, rocks, etc., in shady places; not common. Fruit rare, 

 winter. 



A very delicate plant, resembling slender forms of Amblystegium serpens, but 

 usually in neater, smoother tufts, with the leaves much more shortly acuminate and 

 more oval, more denticulate above, and quite distinct in the fruit. From E. Teesdalet 

 it differs in the short rather faint nerve, and shorter, wider, pellucid cells ; from E. 

 curvisetum in the wider leaves and shorter more pellucid cells; from both in the 

 dioicous inflorescence. 



8. Eurhynchium curvisetum Husn. (Hypnum curvisetum 

 Brid. ; Rhynchostegium curvisetum Schp., Syn.) (Tab. LIV. E.). 



In small cushions, or wider patches, dull green, very short 

 and slender, resembling E. pumilum and E. Teesdalet ; branches 

 numerous, pale and cuspidate at the tips ; leaves very small, 

 lanceolate, gradually acuminate to an acute or somewhat obtuse 

 point ; faintly denticulate above ; nerve slender, reaching about 

 half-way ; cells small, linear-fusiform, 6-10 times as long as 

 wide, rather opaque, thin-walled, laxer and sub-rectangular at 

 base, angular not distinct. Seta short, often curved ; capsule very 

 small, oblong with a distinct neck, lid longly subulate. Autoicous. 



Hab. Rocks and stones near streams ; very rare ; chiefly in the South of 

 England. Fr. winter. 



This species was for long confused with E. Teesdalet, but is quite distinct in its 

 shorter nerve, and usually also in the more acuminate leaves, the rather larger cells 

 with thinner walls, and the more distinct neck of the capsule ; it usually also forms 

 small isolated cushions, but sometimes grows, like E. Teesdalei, in wider patches ; 

 nor are the above secondary characters quite constant. Still it seems on the whole 

 sufficiently distinct. From E. pumilum it differs in the narrower, lanceolate leaves, 

 the longer cells, and the autoicous inflorescence ; it may be usually found in good 

 fruit in the winter months, whereas the fruit of E. pumilum is rare. 



The var. scabrellum of E. tenellum might be easily confused with this species, 

 but a careful examination will show that the leaves in that plant are always more longly 

 and finely acuminate, almost setaceous, with a somewhat longer nerve and distinctly 

 longer cells ; the seta too is longer and the capsule rather larger. 



E. curvisetum appears to be a rarer, and more southern species than E. Teesdalei. 



9. Eurhynchium Teesdalei Schp. (Hypnum Teesdalei Sm.) 



(Tab. LIV. F.). 



Very near the last species, but always in wider, irregular 

 patches; the leaves less narrowly acuminate, often shortly or 

 somewhat bluntly pointed ; the nerve stout, reaching to near the 

 apex ; cells rather shorter, 5-8 times as long as broad, the walls 

 distinctly incrassate ; capsule rather shorter and wider, without a 

 distinct neck ; lid large, with a rather shorter beak. Dioicous. 



Hab. In similar localities to the last, rare. Fr. winter.
