CORNISH FLORA. 57 



rupestre ; and as the late Dr. Ealfs never accepted Mr. Allen's 

 record, it is pretty clear that at the time of publication of my 

 List S. rupestre was not known to occur in Cornwall. I am now 

 able to offer three localities for it. At Pousanooth, where for 

 some unaccountable reason I had j)reviously overlooked it it 

 occupies quite fifty yards of a wayside hedge. I have also found 

 it near Hicks' Mill, in the parish of Gwennap, and Ifiss Eyre has 

 been able to show me another locality for it near St. Agnes 

 village. 



Caucalis arrensis, Huds. I include this species on the strength 

 of the record in Topographical Botany (1883), where specimens 

 are said to have been forwarded to Mr. H. C. Watson from East 

 Cornwall by Mr. Hart Smith. 



Achillea nohilis, Linn. Previously phenomenally rich in 

 aliens, many of which have obtained a permanent hold of the 

 district, Par, in 1902, gave the county a good record for this 

 plant. Ifiss Davey found and directed me to a large and thriving 

 colony, which has considerably extended its borders since. 



Carthamus lanatus, Linn. Another alien which was frequent 

 on the dumping ground near the new gardens, between Truro 

 and Malpas, in 1902. 



Lactuca muralis, Presen. This plant is here included on the 

 authority of the entry in Topographical Botany — "East or West 

 Cornwall, G. S. Gibson.^^ Workers should keep a look out for it. 



Phacelia crenulata, Torr. An alien occurring sparingly at 

 Par, 1902, where it was discovered by Miss Davey. 



Puhnonaria officinalis.^ Linn. On a hedge-bank in a lane 

 leading from Dunheved Cross to Badash farm ; quite established 

 W. Wise. 



Nicotiana rustica, Linn. A number of excej)tionally fine 

 specimens were found at Par, with other aliens in 1902 and 1903 

 by Mr. Tellain. Emit was ripened in abundance. 



Salvia verticillata, Linn. The records for this jdant are: — 

 Launceston, TF. IFise ; Par, F. IT. Bavey ; Malpas, Miss Snell. 



Orchis latifolia x maculata. Hybrids of these two sj^ecies 

 occur in the Trewedna Valley, in the parish of Perran-ar-worthal,
