But it was in the ripe fruit where the chief distinction seemed 

 to he. In uniglumis it was approximately If mm. long, irre- 

 spective of the persistent usually broader-than-long style-base, 

 whilst the fruit of palustris measured scarcely 1| mm. and its 

 style-base was usually longer than broad. This indicates approxi- 

 mately that the fruits of uniglumis minus the style-base equal those 

 of ]}alustris plus this appendage. 



As regards the sculpturing of the fruit (to which Townsend 

 {I. c.) strangely omits reference) it appears that in uniglumis the 

 surface is distinctly punctate- striate, appearing (under a 1 inch 

 power) beautifully marked with cell-like depressions in regular 

 series ; but it is not so in palustris, the fruit of which is normally 

 almost smooth but occasionally slightly punctate-striate. In the 

 latter case the depressions are fainter than in uniglumis, are not 

 in such regular formation nor of the same shape. The colour of 

 the fruit is more or less brown in uniglumis, but in imlustris is of a 

 decidedly yellowish tint. 



I have compared the Skye plants with Scirjms {HeleocJiaris) 

 mamillatus Lindb. fil., of which I have an example collected by 

 the author, but they cannot be placed under that. It seems to 

 hold a middle position between H. palustris and H. uniglumis, 

 having, amongst other characters, the glume character and 

 sculpture of fruit of the former, with the style-base of the latter. 

 It certainly should occur in these islands. 



To sum up, it appears that H. uniglumis may satisfactorily 

 be separated from H. palustris irrespective of the encircling 

 outer-glume character, by its larger, browner fruit with broader 

 style-base and the more obvious punctate-striations on its sur- 

 face. 



These observations are made with the hope that others may 

 confirm them with the help of further material.

Carex sp. Mr. Wallis sent two culms of a most interesting 

 Sedge from Loch Shgachan that matches extremely well the 

 Westerness plant determined by Prof. Klikenthal as " C Goodenoioii 

 X stricta {= turfosa Fries)," and reported in Journ. Bot., 1906, 

 p. 226. C. stricta is not reported from the West coast of Scotland 

 further north than Dumbarton (Ewing) but on the Eastern side it 

 reaches Aberdeenshire.
