XOTES Sri'PLEMEXTAL TO THE FJ.OKA OF BRISTOL 41 



Camus. Obviously this is a veiy different plant from the P. cord at a 

 Desv. (named Briygsii by Sj'me) of which Mr. Briggs sent me 

 a specimen from Plymouth in 1881. That has tiny pyriform fruit, 

 diam. in my example 9-10 mm., " au plus de la grosseur d'une petite 

 noisette" (Kouy), attenuate at the base, and is well described by 

 Boreau, Fl. du Centre, where I find no mention of the form under 

 notice. Kouy and Camus hold, however, that Boreau's description 

 covers several of their varieties. -P. DesegJisei appears to be on 

 record only from Cher in Central France. 



P. intermedia Ehrh. In an old hedge about half a mile W. of 

 Cheddar Gorge, 1913 ! 



[Tamarix tetrandra Pall. When working on the Tamarisks last 

 year Mr. Bucknall found, from specimens gathered by Mrs. Sandwith, 

 that trees of this species had been planted together with some of the 

 common Tamarisk on the farm under Brean Down. T. tetrandra 

 produces its inflorescence on wood of the previous year, whilst the 

 spikes of T. anglica are on the young shoots of the season. T. te- 

 trandra, too, flowers about two months earlier than the other, a fact 

 Avhich, if it be borne in mind, may lead to its being readily identified 

 in other localities,] 



\_Sedu)n sexangulare L. Still on Wyck Rocks, 1917 ! Miss Roper. 

 Walls near the Church at Burrington, S. 1917 ! H. W. Pugsley.~\ 



Saxifraga graniilata L. S. A large patch on a G.W.E. embank- 

 ment near Keynsham ; first observed and identified from a train by 

 Mrs. Sandwith, and a remarkable instance of dispersal by railway 

 traffic. Although a rare species in Gloucester and Somerset, it is 

 common in Berkshire and grows there on railway-banks, so we may 

 reasonably infer that it has travelled to us from the east. Miss Agnes 

 Fry writes (June 1915) that she received from Lady Lawrence some 

 flowers of S. granulata gathered on Lansdown by Bath. The " two 

 places in the Chew Valley, TJwvijjson " {Marshall in Journ. Hot. 

 1917, 183), will very probably be those recorded years ago by 

 Mr. David Fry when lie lived at Stanton Drew {FL Prist. 327). 



[Heracleum giganteiim Fisch. Several strong plants on rubbish 

 in the old lias quarry near Twerton so often quoted for aliens by S. T. 

 Dunn and others ; 1917 !] 



[Coria}idrtfm sativum L. G. Sparingly on a tip at Eastville^ 

 1916! St. Philip's Marsh, 1916; The^'Misses Cobbe.—S. Among 

 mangolds at Failand, 1917 ; D. Williams. On a tip by the Avon 

 at Brislington, 1915 ! Remembering Babington's description "flowers 

 white " I was at first puzzled b}' the rose-coloured petals of the East-, 

 ville plant. But Hooker and Grenier & Godron inform us that 

 the flowers ma}" be pink or rour/edtres. 



Coriander, cultivated in Britain, is said to have white flowers, so I 

 am inclined to tliink that, in this instance, the plant had been intro-. 

 duced with foreign produce and had not sprung from local kitchen- 

 refuse. In the Jjristol district it is a rare stray. It seems odd that a. 

 herb afflicted when fresh with such an offensive odour (the name is: 

 from Kopii because the- green plant, seed and all, stinks of bugs), 

 should yield from its fruit, Avhen distilled in this country, an essential! 

 oil so particulai'ly delicate and agreeable in flavour that it masks the
