or bipinnatifid. Pinnæ growing regularly smaller from the bottom of the 
frond to the top; the lower with a distinct space between them ; the 
upper subcontiguous, the lowest with a distinct stock at most } inch long ; 
deltoid in general outline, unequal at the base, sometimes more produced 
sterior, sometimes on the anterior side, cut down into 3-5 
obversely deltoid contiguous lobes 4-} inch broad, reaching down some- 
i o the rachis, sometimes falling short of it, which are rounded and 
irregularly toothed along the outer border. Central pinnæ deltoid, three- 
the back. Veining flabellate and deeply impressed like that of furcatum 
and splendens. Sori copious, irregular, not reaching quite to the edge of 
the divisions in any direction, finally forming an oblong, roundish, or ir- 
regularly shaped mass, filling up the whole under face, except the edge. 
Involucre moderately firm in texture, greenish, entire. 
Differs from 4. Ruta-muraria by its longer stipes, castaneous to the, 
apex, larger, less compound, more coriaceous frond, contiguous, broader, 
fewer pinnules conspicuously toothed along the outer edge, and distinctly 
impressed venation. It closely resembles 4. ens, Kze., on a smaller 
scale, coinciding in texture and venation, but differing conspicuously in 
size and cutting, by its closer sori soon confluent into a uniform mass and 
by its castaneous stipe. 
THE MOSSES OF OXFORDSHIRE AND THE NEIGHBOUR- 
HOOD OF OXFORD. 
By Henry BoswELL. 
The county of Oxford is not of large extent, its surface nowhere 
rises to any great elevation, nor is there much variety in its soil. It has 
neither coast nor mountains; neither heaths nor bogs of any extent ; but 
an undulated surface, chiefly of oolitic limestone in the northern, and of 
elevated and representative points. Here is a little more variety, from 
the introduction upon the scene of gravel and clay; and so obvious is 
ded. 
The three sections thus indicated vary considerably in their flora: all 
are productive, perhaps beyond the average, in phzenogamous plants, Le 
withstanding that in all of them cultivation 1s carried on to a very igh 
pitch. But the dryness of the atmosphere two-thirds of the year, x 
the absence generally of sites favourable to the growth of ee e 
the region by no means one that a bryologist would be favourably 1u-
