NOTES ON SORBUS 13" 



(Manissadjian, Plantae Orientales, 811); Hungaiy : Waters of 

 Hercules {L. Richter) ; Moravia : Polau Mountains {Heinr. Lmis) ; 

 Germany : near Landskrone in the Ahrtal Valley, Ehine Province- 

 {Sehhneyer) ; S. England : N. Somerset, Brecon, Cheferton 

 [? Chepstow] , Monmouth, Hereford, Radnor {Aug- Ley). S. grcsca 

 Lodd. diifers in its leaves — the same size as in S.porrigens — being 

 roundish, obtuse or obsoletely cuspidate, with short serratures 

 and fewer lateral nerves. Further removed is Sorbiis rupicola 

 (— Pyrns rupicola Syme, Sowerby's Engl. Bot. ed. 3, iii. p. 244, 

 1864 ; Sorhus salicifolia (Myrin) Hedl. Monogr. d. Gatt. Sorbus,, 

 p. 78, 1901) by its obovate or obovate-oblong leaves, quite entire in 

 their lower third or quarter, with short and broad serratures, the' 

 lateral nerves usually about eight, the sepals patent in flower, but 

 not reflexed, the fruits larger (up to 12-75 mm. long and 14-5 mm. 

 broad) and darker red. ... In South Sweden (Kullen, in 

 Scania) only S. rupicola is present ; but I have neither seen this 

 nor S. norvegica grown in gardens." 



S. suhsimilis Hedl., n. sp., is described at length. The author 

 goes on to say: — "This is certainly a homozygotic plant, not yet 

 observed outside Norway, where it occurs chiefly in Sogndal, and 

 is there fairly frequent in several places. In several points it 

 agrees with S. Mougeoti Soyer-Will. & Godr., distributed through 

 the hilly parts of Central Europe ; but it diifers in the very blunt 

 leaves, broadly cuneate at the base [in S. Mougeoti the leaves are 

 of the same shape at the apex and the base] , less densely tomen- 

 tose beneath, and with rather fewer lateral nerves, the remarkably 

 sweet fruits, quite naked (not caesio-pruinose) w4ien dry, the- 

 anthers more or less pink-tinged before dehiscence, rarel}^ some- 

 what whitish. 



" Another homozygotic plant, S. aiiglica, n. sp., or subsp. of 

 S. Mougeoti, occurring in England, which is not yet described,, 

 agrees with S. suhsimilis in its pink anthers and other points, 

 but diverges by the leaves being as a rule shortly acute, sharply 

 serrate towards the tip, with elongated serratures, more densely 

 tomentose beneath, with more numerous lateral nerves, as in 

 S. Mougeoti, and the fruits being usually a little csesio-pruinose." 



S. anglica, which at one time was supposed to be Pyrus inter- 

 media, grows not uncommonly in the Wye Valley (34 W. Gloster, 

 35 Monmouth, 36 Hereford) ; I have a sheet from Craig Cille, 

 42 Brecon, collected by Mr. Ley, who also pointed out to me a 

 tree in Cheddar Gorge, 6 N. Somerset (June, 1906). It appears 

 to be restricted to the mountain limestone. A specimen which I 

 gathered near the foot of the Wynd Cliff (35) in 1895 has been 

 referred byDr. Hedlund to S. anglica x latifolia; no inflorescence- 

 was seen, but the foliage is intermediate, and the putative parents 

 grew near it. He also gave this name to Mr. Ley's " Pyrus- 

 rotundifolia Bechst., var.," from woods near Symond's Yat, 34 

 (1899), and his " P. scandica Asch." (a very different looking 

 plant), from Cefn Fedw, 50 Denbigh (1901) ; as well as to Mr. 

 J. W. White's " P. latifolia Syme " from Leigh Wood, 6 (1905). 



It may be useful to add a few other notes on specimens in my
