injurious extent in the United States, where I have traced it from 

 Boston as far south as Savannah (lat. 32°). 



Chrysanthemum segetum. In cultivated fields, amongst corn, tur- 

 nips and other crops, not uncommon, and sometimes in great profusion 

 in the Isle of Wight, but chiefly confined to the sandy districts, and 

 hence more frequent in West than in East Medina. About San down, 

 Shanklin, Godshill, Chale, Rookley, Niton and many other places. 

 Probably not rare in the county, although I find no notes made of 

 its occurrence excepting at Short Heath, near Selborne, where it is 

 plentiful in the loose sandy soil. Sometimes called here Yellow Boz- 

 zum, more commonly by its general name of Corn Marigold. A 

 showy nuisance, more particularly infesting barley and turnips with 

 us than other crops. Winter wheat at least (and this is the only kind 

 grown here) seems in general free from its contamination. 



\}Pyrethrum Parthenium . In waste or rubbishy places, on banks, 

 wall tops, along hedges and road-sides, chiefly in the vicinity of habi- 

 tations ; not uncommon in the county and island, but scarcely I think 

 truly indigenous. About Ryde, Cowes, &c. Plentiful on sandy banks 

 at Oakhanger, near Selborne, about Petersfield, &c, frequent. Called 

 Whitewort in this island, and an inmate of almost every cottager's 

 garden. 



inodorum. In fields, pastures, waste places, by way- 

 sides, &c, plentiful everywhere ; a rather troublesome weed in tillage 

 lands that are somewhat moist in the latter part of summer, amongst 

 turnips, potatoes and other root crops. Var. |3. maritimum (P. mari- 

 timum, Sm.). Common on banks and rocks along the shores of the 

 Isle of Wight. At Sandown, Luccombe, Ventnor. Shore at Egypt, 

 West Cowes, &c, in abundance. Not distinguishable by any mark 

 that I can perceive from the last, except in such trifling deviations of 

 structure as may reasonably . be attributed to the influence of the sea 

 air. 



Matricaria Chamomilla. In waste places, corn-fields and by way- 

 sides ; apparently a local, if not a rare plant in Hants, and which, 

 though common along the coast immediately opposite, I have never 

 succeeded in finding in the Isle of Wight. In several parts of Hay- 

 ling Island, at South Hayling, &c, but not abundantly. Portsea 

 Island. Pretty plentiful along the road from Cosham to Havant, about 

 Drayton and onward to Farlington, where it is very common around 

 the water-works and in the lane leading to them, also on the line of 

 the Southern Counties Railway from Havant to the Fareham Junction. 

 At Wymmering, along the road-side near the turnpike, and at Por-
