44 THE JOUKXAL OF EOTAXY 



the limestone ridge between Tickenham and East Clevedon, 1915 ! 

 Abundant on waste heaps at Portishead Soutli, 1915 ! 



[? A. Tournefortiana Rehb. An Asian introduction. Several 

 plants in a cabbage-patch on Wapping Wharf, Bristol Harbour ; and 

 on rubbish at St. Anne's, Brislington, 1916 ! Occurred at Didcot, 

 1895 {Druce) ; and at Ledbury, 1907 and subsequently {Bickham). 

 Of peculiar habit — erect, slender, unbranched and tall, up to four feet 

 in height. In Koch's Synopsis this species is described as being 

 glandular- viscid, but our plants are not so.] 



Doronicum Pardalianclies L. Although not seen for many years 

 in the Glen Frome locality {Fl. Brisf. 378), it is still there, 1917 ! 



\_Senecio squalidus L. Is steadily spreading in the district. 

 Portishead Station -^^ard, 1914-16 ! On a wall by Wellington Ten-ace, 

 Clevedon, 1911-14 ! Hiss Livetf. Banwell ; and Kewstoke Bay ; 

 Bev. E. Elhnan. Two plants by the roadside at Clapton-in-Gordi'no, 

 1916 ! Misses Ctmdall.—Ya.r. leiocarpus Druce. With glabrous fruit. 

 Two large clumps on a railway-bank near Hallen, G., 1916 ! Miss 

 Boper. Clevedon, 1914; Miss Livetf. Portishead Dock, 1916! 

 Mrs. Becfinald Brice. The specimens well agree with Mr. Di'ucc's 

 own gatherings.] 



\_Xanihium Sfricmarium L. Two or three jjlants in St. Phiiij)"s 

 Marsh, 1916! Miss Boper. One on Wapping Whai-f, Bristol Har- 

 bour. Brislington, S. ; Miss M. Cohhe.'] 



[? Ambrosia trifida L. Site of a mule camp at Webbington under 

 Crook's Peak, 1916 ! Miss Boper, and in a similar field off Yanley 

 Lane, Long Ashton, 1916-17 ! The identification is not free from 

 doubt as the plants did not agree well with any species descrilied in 

 DeCandolle's Brodronnis. The structure of the inflorescence is hardly 

 that of A. trijida.'] 



Centmirea solstitialis L. In a spot Avhere turf had been removed 

 from pasture near Northwoods Asylum, G., 1914 ! Ivor W. Evans. 

 Still in St. Philip's Marsh as a casual, 1916 ; G. C. Bruce. 



Carduvs acaulis x arvensis. On a plant gathered by Miss Roper 

 in a rough field at Failand, S., the Eev. E. S. Marshall remarked that 

 allowing for diffei'ences of date and locality, and noting the inter- 

 mediate foliage and short spines at the tip of many of the phyllaries, 

 it came very close to one gathered near Monmouth in 1908. Both 

 were to be considered this hybrid, though not entirely without doubt, 

 as the seeds of Miss Roper's plant appeared to b'e well developed, and 

 liybrid thistles are very generally sterile. 



[Carthonn/s tinctorius L. Alien. Several plants on house refuse 

 north of Horfield, G., 1915 ! Ivor W. Evans. One on a tip at 

 Eastville, 1916. St. Philip's Marsh ; G. C. Druce. Waste ground 

 by Cranbrook Road, 1917 ; C. E. L. Gardner. A handsome orange- 

 flowered Composite, probably native in Egypt and Ab3\ssinia, and 

 cultivated in many parts of the world for the colouring-matter yielded 

 b}^ the flowers. On account of its frequent occurrence as an outcast 

 in southern countries it has been included in the European flora by 

 ^N^^man and by Gandoger. In Britain, however, it must be rare, 

 as it Avas unknown to Mr. Dunn when compiling his Alien Flora. 

 C. tinctorius has a special claim to notice here, for according to old
