BRITTEN ON SPONTANEOUS EXOTICS. 265 



Buffonia tcnuifolia, L. " Said to have been formerly found on Houn- 

 slow Heath, and about Boston in Lincolnshire. It was unsuccessfully 

 sought in the latter place by Sir Joseph Banks, who thought that Bwpleu- 

 rum tenuissimum had been mistaken for it. Perhaps Moenchia crecta was 

 thus mistaken on Hounslow Heath." Cyh. i. 223. 



Cucuhalus baccifcr, L. ** Gathered in hedges in Anglesea," and com- 

 municated to Dr. Richardson by D. Fowlkes. R. Syn. Hi, 267. " Bev. H. 

 Davies never found it." B. G. i., 4. *' In the margin of my coj^y of 

 Jxay's Synopsis against G. PUnii (C. bacciferj, a former possessor of the 

 book has written, as a habitat ' Springfield, Essex,' " H. O. Stephens, in 

 Phyt. i., 295. O.S. There can be little doubt that, in each of these cases, 

 some error must have occurred, but the plant certainly grew in the Isle of 

 Dogs, though it may now have disappeared thence. ** The locality in the 

 Isle of Dogs is on the banks of the ditch on the left hand of the road from 

 Blackwall to the Ferry House, and there, if not truly wild, it is at least 

 perfectly naturalised," Geo. Luxford, in Phyt. i., 255. O.S. It existed 

 here as recently as 1852, when it was gathered by Mr. Thomas Westcombe, 

 of Worcester, who " found the plant growing in considerable abundance in 

 the old station, and thought there was no probability of its becoming 

 exterminated." Phyt. iv„ 609. O.S. Are there any grounds for suppos- 

 ing that the plant was here introduced ? or is it not rather a genuine 

 British species ? I shall be glad to learn whether it has been more 

 recently observed in the Isle of Dogs. 



Order XIV.— Malvaceae. 



Malva Alcea, L. " Frequent on the borders of fields, &c.'" B. Syn. 

 Hi., 452. *' In the counties of Warwick, Leicester, and Nottingham." 

 Flora Anglica. There can be no doubt that the plant here intended by this 

 name is only M. moschata ; the true ill . alcea not having been found in 

 England, though it is a species not unlikely to occur. A native of 



M. jnisilla, E. B. M. horealis, Wallm. " Said [by Hudson] to have 

 been found at Hythe in Kent, which requires confirmation. Whether this 

 is truly the species intended by Bay (and by Hudson under the name of 

 M. parviflora) may be still uncertain. It has also been reported to me from 

 Glamorganshire." Cijb. i., 240. *' Specimens gathered in Pembroke- 

 shire." With. Arr. Hi., 599. 



M. Nicceensis, All. " Some few specimens of this species were foimd 

 by Mr. Thomas Moore in * Battersea Fields, on the embankment opposite
