Tue plants to which the following notes refer were mainly 
gathered between 1889 and 1891, parts of Aberdeenshire, Forfar- 
m though they may appear 
numerous, do not embrace all that we have collected of doubtful 
Lindeberg for determination. In a few cases a name occurred to 
us for some of Mr. Hanbury’s numerous doubtful plants, and at his 
request we incorporate in our paper some of these identifications 
which appear to extend the distribution of the species. 
It remains to add that the few species and varieties here pub- 
lished for the first time are not described in any case by us 
collectively, but by one or other of us se arately ; and for this 
reason the name of the actual author is always appended to the 
n. Sp. or noy. var. 
We add the usual * to denote new county or v.-c. records, pre- 
H. graniticolum, n.sp. A plant gathered in Corrie Etchachan, 
under Ben Muich Dhui, §. Aberdeen, in 1884, and again in 1889, 
belonging to the alpinum section, does not agree with any named 
species. It may possibly coincide with Prof. Babington’s H. 
melanocephalum Tausch., v. insigne, but the description of this in 
lentum Backh., H. alpinum Backh., and H. eximium y. tenellum
