ULOTA. 241 



3. Ulota Bruchii Hornsch. (Weissia Bruchii Lindb., Braithw. 



Br. M. Fl.) (Tab. XXXIV. F.). 



Much resembling the last species, but with rather more 

 compact tufts, the stems less prostrate and creeping ; the leaves 

 more curled when dry, though less so than in the next species; 

 the capsule usually of a duller colour, rather narrower, when dry 

 and empty distinctly fusiform, much contracted at the mouth ; 

 peristome double, inner of 8 or 16 processes. Lid with a rather 

 long beak. 



Hab. Trees, rarely on rocks, frequent. Fr. late summer and autumn. 



As above stated this is a very difficult plant to recognise from the last, though the 

 leaves are perhaps always more curled when dry, while in U. L>rummondii they are very 

 slightly twisted, and in some cases almost straight. The presence of inner processes 

 is a very uncertain character. I do not find any reliable distinction in the hairiness 

 of the calyptra. 



U. Bruchii may be readily known from U. crispa and its allies by its greater 

 robustness, the colour usually, though not always, of a darker and duller green, its 

 longer leaves less closely and less strongly curled when dry, its capsule on a longer seta, 

 and much larger, usually at least twice as long as in U. crispa, of a firmer texture, 

 and of quite different form, never contracted below the mouth as in that species, and 

 usually, especially when dry and empty, distinctly narrowed to the mouth, which is 

 very small, so that the whole capsule, including the neck, has a narrowly fusiform 

 shape. Starved specimens, however, are sometimes much like U. crispa var. 

 intermedia. The areolation is a little larger than in those species, but the difference 

 is hardly enough marked to determine specimens in the absence of other available 

 characters. 



4. Ulota crispa Brid. (Bryum crispum Gmel. ; Weissia 

 ulophylla Ehrh., Braithw. Br. M. Fl.) (Tab. XXXIV. G.). 



In small dense round cushions, bright green or yellowish. 

 Leaves as in U. Ludwigii but rather longer, with a wider band of 

 hyaline cells at each side the expanded base, when dry strongly 

 and closely curled. Seta and capsule shorter than in the last ; 

 calyptra very hairy ; capsule when ripe and after the fall of the 

 lid pale green or whitish brown, thin-walled, smaller than in the 

 last, sub-urceolate, distinctly contracted below the mouth, then 

 wider, and rather suddenly narrowing into the neck ; becoming 

 darker when old, and narrower ; ribs narrower than in U. Bruchii; 

 lid with a shorter beak than in that species ; peristome teeth in 

 pairs, so as to appear 8 in number, at first spreading, afterwards 

 recurved ; processes 8, rarely 16. Autoicous. 



Var. p. intermedia {Ulota intermedia Schp., Syn.). 

 Resembles the type in everything but the capsule, which, when 

 ripe and empty is in the dry state oblong-cylindric , of the same 

 ■width throughout, not contracted below the mouth, rather more
