and in part the venation of the leaves, the often erect leafy- 

 peduncled catkins, and the structure and colour of the style and 

 stigmas ; and from nigricans the somewhat tomentose twigs and 

 leaves, the greater thinness of the latter, and their greater 

 tendency to become black in drying, the often longer petioles, 

 and the often longer pedicels of the capsules. But, as Andersson 

 remarks, some specimens are very difficult to separate from 

 nigricans, and others pass imperceptibly into My r smites, and 

 thus it is often by no means easy to determine some of the less 

 intermediate examples.

of the latter, though it has been passed over as Myrsinites and 

 sometimes as nigricans. I have seen good intermediate speci- 

 mens from Perthshire, Forfarshire, and Aberdeenshire— first 

 gathered in the latter two counties by J. H. Balfour, Greville, and 

 their contemporaries ; and in addition many examples gradually 



inites or nigricans, and often very difficult 



to separate.

Neither Wimmer nor Andersson seem to have been acquainted 

 with the o* plant, though the former quotes of the catkins " 6 

 elongati, graciles." The tf has, however, been found on Ben 

 Laoigh by the Messrs. Groves, and on Ben Heasgarnich by 

 myself. These tf plants have leaves near Myrsinites, catkins 

 short, thick, on leafy peduncles, and anthers subglobose and 

 yellow, this yellow colour being the chief point in which they

herbarium specimens (now in the possession of Dr. Eoy, of 

 Aberdeen)— from the Corrie of Loch Kandor, where the hybrid 

 is common—are very close to, if not identical with, Myrsinites, 

 though they are too poor for absolute certainty. 



A hybrid between 8. Myrsinites and 8. phylicifolia probably 

 occurs in Britain, but I have not yet seen examples sufficiently 

 certain to enable me to include it in the list.
