Dr. Lindsay also records what he calls var. intermedium, 



99. Rosa spinosissima, Linn. — H. 



Discovered by Swein Paulsen, and sent by him to Hooker. He 

 wrote with the specimen, " crescit in rupe unica ad villam Selja- 

 land." Thienemann and Giinther were directed to the spot by 

 Paulsen, and " were fortunate enough to find the rose growing on 

 a detached basaltic rock. There w^ere altoo^ether about twenty 



bushes, about two feet high. It was in fruit on Aug. 27." 

 (Eeise im Nord. Europ. p. 332.) Seljaland is a farm between the 

 foot of Eyja:Qalla Jokull and the Markarfljot, in lat. 63° 36'. 



Lindley says that '' its strong vigorous shoots led Mr. Hooker 

 into the error of considering it jB. hiberniea,^^ 



Fries tells us (Nov., ed. 2, p. 157) '^ specimina Norvegica hujus 

 speciei [.B. spinosissima] cum Islandicis [-B. liihernica^ Hook. It. 

 Is.] a Morck lectis et communicatis conveniunt/' 



There can be no doubt that this is the R, canina which Solander 

 saw in S. Paulsen's Herbarium. 



Morck seems, from Gliemann's remark, to have originally sup- 

 posed that his specimens belonged to the JR. hamtscliatica \ hence 

 the introduction of that name into the Icelandic list. Gliemann 

 apparently did not see the specimens, and so has both 5. ^^- 

 hernica and jB. hamtscliatica in his catalogue. Lindsay, for the 

 same reason, has two roses which he calls B. villosa, var. Tiibernica, 

 and H, pimpinellifolia. Paulsen's specimens in the Kew Herba- 

 rium are certainly a state of R, spinosissima^ of which B.pi'm- 

 pinellifolia is a synonym. There are similar specimens given by 

 Da-wson Turner in the Herbarium at Newcastle-on-Tyne, as I 

 learn from Mr. J. Gr. Baker.

 Henderson saw stunted trees in Morardal, near Skaptafell, by the 

 Skeidara river. Budarhraun, Mk. Briamsloek, Kr, 



Hooker records P. domestica on the authority of a specimen 

 obtained by Sir G Mackenzie from a tree eight feet high, whicli 

 was growing out of a cleft of lava at Budirstad in Snaefell 

 Syssel. Mackenzie also had it brought to him from Eyjasfjord, 

 where we are told by Mohr that P. Aucuparia grows near Modru- 

 fells Hospital. Eobert says that the trees by the Hospital are 

 P. Aucuparia 3 and denies the existence of P. domestica in Iceland.
