Sisymbrium . Waste ground, West Dock Reser- 

 vation, Hull, E. Yorks., v.c. 51, Aug., 1900.— C. Waterfall. 

 Named S. Loeselii, L., by Mr. J. Britten, and no doubt 

 rightly. It has been previously found near a railway at 

 Didcot, in Berkshire. It seems to be indigenous to the 

 Altai region, where it is common on river banks. — S. T. Dunn. 



Medicago falcata, L. (1). Upper Roedean (road -side), 

 Sussex, July, 1900. (2). South of Lighthouse, Kingston, 

 W. Sussex, August, 1900. — T. Hilton. — Not an infrequent 

 weed of waste places in Britain, though apparently not 

 recorded as a native here or elsewhere in N. Europe.- — 

 S. T. Dunn. 



Lathy vns liirsutns, L. Stanmer, E. Sussex, cultivated 

 land, 1900. — T. Hilton, This is another instance of the 

 appearance of this species in connection with agriculture. Its 

 natural appeai ance near cultivation has led to its admission as 

 an indigenous British plant by some authors, but these cases 

 are so few compared with those in which its origin is obviously 

 alien, that we must be content at present, like botanists 

 of other parts of N.W. Europe, to regard it as an introduced 

 species. It is certainly native in bushy places in Central and 

 E. Europe and on dunes in Tunis. — S. T. Dunn. 



Cotoneaster inicrophylla. Hedge bank, in Pabo village, 

 Pabo Hill, Carnarvonshire, v.c. 49, July, 1900. — C. Waterfall. 

 C. microphylla, Wall. This is the species that is said to be 

 naturalized on Brean Down in Somerset, and if it has held its 

 own on that exposed and wind-swept promontory, it will 

 survive as a relic of garden culture in other places. It is a 

 native of the Himalaya region. — S. T. Dunn. 



Xanthium spinosmn, L. (1) Waste ground, West Dock 

 Reservation, Hull, E. Yorks., v.c. 61, Sept., 1900. — 

 C. Waterfall. (2) South of Lighthouse, Kingston, W\ Sussex, 

 Sept., 1900.— T. Hilton. On a specimen of Mr. Hilton's 

 gathering Mr. S. T. Dunn remarked — " Ripe fruits are found 

 on this plant in England only under very favourable conditions. 

 That this is due to its late flowering is suggested by the 

 present example which had only immature achenes when 

 gathered in September.
