hard-trodden parts. This latter plant is now well established in 

 the valley of the Thames ; it is almost^ if not quite, as common 

 as D. tenuifulius. Koniga maritima may probably in some rare 

 cases be semi-spontaneous, or possibly spontaneous in its growth, 

 but such does not appear to be the case in these parts. It has 

 been collected in great abundance at Battcrsea Park pier, also at 

 Parson's Green, and in some other parts near London; but in 

 all these places it may have sprung up from seeds which were in 

 the soil, mould, or rubbish laid on these spots where this plant 

 was seen growing, Camtlina satwa is one of the unintentionally 

 cultivated weeds, and is not uncommon among crops of Flax. In 

 Lincolnshire it has been seen among growing Avheat. 



Vella annua [Carrichtera of some botanists), in books localized 

 on " Salisbury Plain, and not seen since the time of Ray,'' was 

 plentiful for two or three years at Wandsworth steamboat-pier, 

 and sparingly about Battcrsea : it must be reckoned among the 

 accidental plants Avhich appear about as rarely as the comets. 



Lepidium iberis, L., or L. graniinifoliuni, was seen only once, 

 and then only one specimen. This species was identified at Kew. 

 L. Draba has been well established for at least eight years at 

 Wandsworth, where it covers a great extent. At Battcrsea also 

 it has appeared for the same length of time, but it has not spread 

 so much in the latter locality. In a chalk-pit at Northfleet, 

 near Gravesend, it is now well established. 



Rapisirum rugosum and Enarthrocarpus lyratus have also 

 abounded at Wandsworth. They perfect seeds, and are probably 

 self-propagated. These grow only on fresh soil. 



The Malvacecs entered in the list grew abundantly and luxu- 

 riantly, both on the soft and on the hardened ground. Althaa 

 hirsuta, peculiar hitherto to Cuxton, appeared sparingly and at 

 intervals. 



Erodium ciconium was plentiful and strong for some years. 

 E. littoreum was only observed one year, late in the season, at 

 the mouth of the Grosvenor canal. These are both south Eu- 

 ropean plants ; only E. ciconium has a greater northward range 

 than E. littoreum has. 



Impatiens parviflora appeared pretty well established about Bat- 

 tcrsea, but the works necessary for the Crystal Palace and West 

 End Railway have probably exterminated it. In 1851 I took a 

 few plants into my garden, and it has grown up spontaneously
