hedges at Kew, of a bramble that comes in between Balfourianus and 

 cori/UfoJiiis var. iiiterniedius. It has angular barren stems, copious 

 large prickles on the rachis of its panicle, and ascending fruit-sepals. 



Li/thnan hyssojjifoJiiDn. This I gathered last year in small 

 quantity on the Surrey side of the Thames above Kew Bridge. 



Ht'losciadiu)}}. nodijiorum var. ochreatuw, DC- [Slum lujhridum, 

 Merat.) Barnes Common, Surrey, G. Nicholson. This is a 

 dwarf form of nodijiorum with small obtuse leaflets, one to three 

 lanceolate bracts, and flower-umbels on peduncles one-quarter to 

 one-half of an inch long. From H. repens, which is very rare in 

 Britain, with which it is sometimes confounded, it differs by its 

 assurgent flowering stems and shorter peduncles. 



Mentha puhescem. Pengersick Castle, J. Cunnack ; and stream 

 on Pra Sands, nearHelstou, Cornwall, J.Ealfs. This is the first time 

 we have had a supply of this interesting mint, which was gathered 

 a generation ago in the neighbourhood of Penzance by Mr. Borrer, 

 but has been long sought for in vain by the resident botanists. 



Acanthus viol lis. Thoroughly established, on a hedge-bank at 

 Treath Manaccan, Cornwall, growing with Allium Ampelopyasum, 

 W. B. Wateefall. 



Orohanche elutior. It seems quite clear now that the Epsom 

 Orohanche, which has been called lucorum, is -only elatior pure and 

 simple. Mr. A. Bennett sends it this year from " fields between 

 the town and downs, proceeding from the back of the grand stand 

 towards the town of Epsom." 



Solanimi nigrum. A form with the fruit bright green when ripe 

 [8. luteo-virescens of Gmelin), from rubbish-heaps at Mortlake, 

 Surrey, G. Nicholson. 



Veronica Buxhaumii. A variety with very hairy stems, flowers 

 smaller than usual, and fruit-carpels not ribbed till the plant is 

 dried, from waste ground at Kew, G. Nicholson. 



Sijmplnjtu})! asperrimum. The introduced British plant which 

 has been so called by Babington in ' Flora Bathonensis,' and Dr. 

 Boswell in ' English Botany,' of which Mr. Flower sends us a good 

 supply this year from the long-known station in the neighbourhood 

 of Bath, and Kev. W. H. Purchas from Grange Mill, near Wirks- 

 worth, Derbyshire, is evidently not the true wild 8. asperrimum, 

 M. B., of the Caucasus, but a garden hybrid between that species 

 and 8. officiyiale, which is often planted for forage, and which 

 is most likely 8. peregrinum, Ledeb., Fl. Ross., vol. iii., p. 114. 

 8. asperrimum is a plant that grows five or six feet high, with 

 stems densely clothed with very short, rigid, bristly pubescence, 

 many of the bristles springing from white calcareous tubercles, 

 leaves rough over the face with bristle-pointed white tubercles, 

 like Anchusa italica, lower leaves of the flowering branches ovate 

 and contracted suddenly at the base, and a flower-calyx not more 

 than one-eighth of an inch long, with linear-oblong obtuse teeth 

 not longer than the tube. The naturalised hybrid has much less 

 bristly stems, leaves without white tubercles on the face, lower 

 leaves of the flowering branches both absolutel}^ narrower and 

 narrowed more gradually at the base, and a flower-calyx like that 

 of ojlicinale, with acute linear teeth twice as long as the tube. Mr.
