176 ANNALS OF SCOTTISH NATURAL HISTORY 



branched in the upper half; leaves very minute, on an average 

 .2 by .08 mm., erect and closely appressed when dry, spreading 

 a little when moistened, concave and broadly ovate, almost cordate 

 below, so as to give a beaded or rope-like appearance to the whole 

 stem much as in Grimmia torquata ; shortly and rather broadly 

 acuminate, with a bluntish rounded apex ; cells of the pagina 

 roundly oblong, or merely oval with thickish walls, distinct and 

 separate, small, .on-.oi6 by .006-9 mm - -marginal cells in one or 

 two rows, smaller, oval, .ooS-.on mm. in the long diameter, in 

 upper half of leaf cells a little longer (-018 mm.), margin plane, 

 but as a rule shortly incurved quite at base, entire or occasionally 

 rendered slightly irregular by protruding marginal cells ; nerveless, 

 except rather frequently a middle row or two of narrow cells in 

 lowest fourth (.024 by .004 mm.), soon turning yellow, may be 

 said to constitute a nerve. 



This moss differs widely in its areolation from the two mentioned 

 above, in the breadth of the leaf below, in the broader and shorter 

 acumen, as well as in the concavity of the lower half. On sandy 

 earth close to the sea. 



CYNODONTIUM GRACILESCENS (Web. and Mohr.), which has long 

 been looked for, has at last been found, but only with young fruit. 

 The papillae, which give a distinctive character to this moss, are on 

 both sides of the pagina, are broad at base, bluntly conical, and 

 from .003 to .005 mm. in height. They are also seen on the back 

 of the nerve although more sparingly. They are apt to collapse as 

 my continental specimens indicate. Near Balmaha, Loch Lomond, 

 3oth March, 1907 (L. W. STIRTON). 



ADDITIONS FOR 1907 TO CENSUS OF 

 SCOTTISH HEPATIQE. 



By SYMERS M. MACVICAR. 



THE present paper contains 97 records of species examined. 

 Most of the specimens were found in 1 907, but a few were 

 collected in previous years. Scapania obliqua (Arnell) 

 Schiffn., a plant perhaps too nearly related to 5. uliginosa to 

 be considered specifically distinct, is an addition to the 

 Britannic flora. LopJiozia Baueriana, which was previously 

 recorded as a variety of L. Floerkii, is now given as a 

 species.
