58 ANNALS OF SCOTTISH NATURAL HISTORY 



seem to have a tendency to wear off, though it cannot be said to 

 be glabrescent. There are some other slight differences between the 

 two, but in all their main characters they agree with each other and 

 with the Belfast rose. The fruits in both are abortive to such an extent 

 that I have not seen any sufficiently advanced to make sure whether 

 the sepals become erect or not, and until this point be determined, 

 one cannot decide whether the second parent is R. dumetorum, 

 Thuill, or R. coriifolia, Fr. There can of course be no doubt that 

 the other parent is R. pimpinellifolia, Sm. W. BARCLAY. 



Casuals near Aberdeen. During the year 1907 I have con- 

 tinued to keep a watch on the plants that spring up on rubbish 

 deposits around Aberdeen. The most productive site has for a few 

 years been on the Links east of Old Aberdeen, where quantities of 

 town refuse have been deposited to form a drive along the coast 

 and a football ground on a low part, which has thus been raised 

 above the level of the highest tides. The football ground has for 

 some time received almost all the refuse ; and a sparse vegetation 

 has grown on parts of the surface, where not destroyed by new 

 deposits. During 1907 I have found, among numerous other 

 casuals, the following, none of which has been previously recorded 

 from this part of Scotland : Sisymbrium Columnce, Jacq., /3 * ; S. 

 tanacetifolium, L., a ; Erysimum repandum, L., a ; Lepidium incisum, 

 Roth., ft ; Silene cretica, L., a, weed in my garden, among straw- 

 berries ; Medicago littoralis, DC., /3 ; Melilotus sulcata, Desf, y ; 

 Trifolhim Thalii, Vill., a; Apium leptophyllum (DC.), F. Muell., a; 

 Schkuhria isopappa, Benth., /3 ; Senecio aralncus, L., y ; Centaurea 

 melitensis, L., y ; Statice Suworowi, Regel, a ; Phleum tenue, Schrad., y. 

 Of casuals previously recorded from near Aberdeen, but extremely 

 rare here, I found on the football ground Sisymbrium Sophia, L., (3, 

 and Hordeum murinum, L., a. JAMES W. H. TRAIL. 



Fungi from the Isle of May. During their sojourn on the 

 Isle of May for the purpose of witnessing the migratory movements 

 of birds, the Misses Baxter and Rintoul collected the following 

 species of Fungi, specimens of which they submitted to me for 

 identification : 



Tricholoma grammopodium, Clitocybe dealbata, Pholiota mutabilis, 

 Naucoria semiorbicularis, N. melinoide, Stropharia aruginosa, 

 S. semiglobata, Psilocybe fcenesecii, Panceolus separatus, Hygro- 

 phorus pratensis, If. virgineus, If. coccineus, If. psittadmts, 

 Clavaria inequalis, C. fusiformis, Calocera viscosa, Bovista 

 plumbea. A. B. STEELE, Edinburgh.
