 Order III. — PAPAVERACEiE. 



Papaver nudicaule, L. " Was found by Professor Giesecke, of Dublin, 

 growing singly among rocks and glens in the bills at Acbil-bead in the 

 North- West of Ireland." Eng, Bot. v. 4. Some gross error must have 

 occurred, as no one else has ever seen the plant in the locality given. It 

 is a native of Siberia. 



Argemone mexicana, D.O. Is included by Mr. Winch among the 

 plants of the " ballast hills of the Tyne and Wear ; " but has not been met 

 with elsewhere in England. It is, as its name denotes, a native of Mexico. 



Escholtzia calif ornica, D.C. This common garden annual occurs not 

 unfrequently on rubbish heaps near the Metropolis. I have this year 

 found it in such situations in Battersea Park, and in the grounds of 

 Chelsea College. 



E. crocea, Benth. *'I found it growing among stones between Dron 

 and Nydie Mill, Fifeshire, at the edge of the footpath." It " likewise 

 occurs in great abundance in a piece of ground lying waste in consequence 

 of the Edinburgh and Northern Kailway operations." G. Lawson in Phyt. 

 Hi., 136. O.S. (1847.) Both this species and the last are natives of Cali- 

 fornia. • 



Glaucium phoenicium, Gaert. This plant was at one time believed to 

 inhabit sandy fields in the county of Norfolk ; but time has shown that 

 if it ever occurred there it could only have been as a casual introduction : 

 it has also been reported from Portland Island. In Irvine's London Flora, 

 published in 1838, it is stated to have been " found near the turnpike, 

 about a mile from Brighton, on the beach " (p. 303) ; and in this neigh- 

 bourhood it appears to have been noticed as recently as 1859 ; for in Phijt. 

 Hi., 285. N.S., we read that Mr. Gerard Burton, on June 14th of that year, 

 " gathered a single specimen on the seashore near the eastern end of Brigh- 

 ton," which specimen, he adds, " does not at all favour the idea that it was 

 an escape from cultivation." In Phyt. iv., 156. N.S., this locality is stated 

 to be " not far from Hove." In Surrey it appeared plentifully at the 

 Wandsworth steamboat pier locality, where it continued from 1852 to 1865, 

 (see H,B.P. 726); here " some of the examples unquestionably perfected
