ULOTA. 243 



leaf than the other ; basal cells all narrowly linear or vermicular 

 except 1-2 rows of rectangular hyaline cells at margin; the 

 narrow cells are also continued high up on each margin, only very 

 gradually passing into the short, rounded-elliptical cells of the 

 upper part, so that even above half-way up the marginal cells in 

 3-5 rows are distinctly longer and narrower than the median ones. 

 Calyptra pale, glossy, with a very few scattered hairs. Capsule 

 on a rather long seta, much resembling that of U. intermedia, 

 oval-oblong, when ripe and empty hardly contracted either at or 

 below the mouth ; when old rather fusiform and frequently 

 narrowed below the orifice ; rather less deeply sulcate than in the 

 last species. Peristome double. Autoicous. 



Hab. On shrubs and young trees ; rare. Fr. summer. 



This species differs not only in the almost glabrous calyptra but also markedly 

 in the form and structure of the leaves ; the deep fold or vitta (whence the specific 

 name vittata of Mitten), the narrower base, the absence of the wide bands of hyaline 

 cells, and the band of elongated cells extending high up the margin of the leaf, all 

 -afford clear distinguishing characters. 



U. calvescens has hitherto not been detected on the Continent. It has been found 

 in several places in Ireland, but is extremely rare in England and Scotland. 



6. Ulota phyllantha Brid. (Weissia phyllantha Lindb., 

 Braith. Br. M. Fl.) (Tab. XXXIV. I.). 



Densely cushioned, \-\\ inches high, more robust than the 

 previously described species, green or yellow above, rich reddish 

 brown or blackish below. Leaves very closely curled when dry, 

 more resembling those of U. calvescens than any other species, 

 but broader, and without the marginal furrows at base, somewhat 

 obtusely pointed, and apiculate with the excurrent brownish 

 nerve, which bears at the apex a dense cluster of reddish brown 

 clavate jointed gemmae ; margin recurved at base ; areolation 

 almost as in U. calvescens. Perichaetial bracts much longer than 

 the leaves ; capsule oblong, not contracted at or below the mouth. 

 Calyptra slightly hairy. Peristome double ; outer of 16 teeth 

 arranged in pairs, reflexed when dry ; processes 8, short, 

 fugacious. 



Hab. Trees, and rocks near the sea. Not uncommon. Fruit exceedingly rare, 

 spring or summer. 



This very interesting plant has only quite recently been found in fruit, first by 

 Howell, in Oregon, and since then in two or three herbarium specimens, including a 

 single capsule from Tunbridge Wells and a few from Killarney ; and quite lately it 

 has been detected in several N. American localities. C. Miiller and Kindberg make 

 two species of what has usually been considered U. phyllantha, viz., U. phyllantha 

 proper, taller, yellowish, brown below, with longer seta and capsule, growing on
