250 ANNALS OF SCOTTISH NATURAL HISTORY 



The very dry season was prejudicial in many localities, but allowed 

 freer access to swamps than can usually be had. Among the plants 

 found by me were two not previously known to occur in South 

 Aberdeen (V.C. 92). 



Utricularia ochroleuca was found in numerous small, shallow, 

 swampy pools on moors over an area of several square miles, often 

 in abundance, and was by far the most common bladderwort in the 

 district, though intermedia, minor, and vulgaris all occur here and 

 there in the district. Now inclining to intermedia and now to minor 

 in structure and appearance, ochroleuca gives very strongly the 

 impression of being a hybrid between these two species. Easily 

 and rapidly multiplied by its apical buds, it does not require to 

 produce seeds ; and it appears to be replacing both intermedia and 

 minor around Dinnet. Both had been known from that district for 

 a good many years ; and ochroleuca had been probably overlooked 

 as minor, which it often greatly resembles. All the species of 

 Utricularia are very uncertain in their times of flowering in the 

 north-east of Scotland, several years frequently passing without a 

 flower being observed, and occasionally many flowers showing 

 themselves at the same time. 



Eriophorum panicnlatum, Druce (E. latifolium, Hoppe), was 

 found by me in fair quantity on a swampy slope about half a mile 

 south of the Bridge of Dinnet. It had not previously been recorded 

 from any county between Forfar (Glen Dole) and East Inverness.

Scandinavian Roses. Under this heading a short paper, by 

 Carl Traaen, in the "Journal of Botany" (pp. 298-300), calls attention 

 to papers of much interest to Scottish botanists, by Dr. S. Almquist, 

 issued during the years 1907, 1910, and 1911. As these papers 

 state conclusions with regard to the classification of the roses differ- 

 ing from those of other systematists, but which are expressed in 

 Swedish, there is reason to welcome the brief statement of their 

 purport in the "Journal of Botany," as regards the forms included 

 by Dr. Almquist under R. canina and R. glauca (including coriifolid). 

 The best character to distinguish these two, regarded by him as 

 true species, he finds in the styles, which in canina are prolonged 

 a little above the opening of the disk and are more or less separated, 

 while in glauca they are short and densely coherent. 



He unites glauca and coriifolia under the name Afzeliana, Fr., 

 including in this varieties that differ in colour and in surface, the 

 hairy being derived from glabrous types. He thus divides R. 

 Afzeliana into two glaucous groups, glauca, Vill. (glabrous), and 

 glautiformis, Almquist (hairy), and two green groups, virens, Wg. 

 (glabrous), and Tirentiformis, Almquist (hairy). He does not regard 

 the direction of the sepals of the fruits as diagnostic ; but he divides 

 these four groups into parallel series, or sub-species, by the nature
