BRITTEN : LONDON BOTANY.

ecespitosa, and Bidens cernua, are to be found about most of the ponds ; and 

 Filago minima is plentiful on the gravelly parts of the common. In the 

 deep cutting opposite the prison, Melilotus vulgaris and Medicago sativa, are 

 plentiful and well established. Veronica AnagalUs, V. scutellata, and Equise- 

 tum Telmateia, grow nsar the water ; and towards the top of the cutting, 

 Marruhium vulgare and Senecio sylvaticus are abundant, with Helminthic 

 ecMoides in less quantity. On the gravel just outside the cutting Trigonella 

 ornitJwpodioides, Trifolium suhterraneum, and Plantago Coronopus cover the 

 ground, while on the waste ground opposite, are Koniga maritiraa, Matrica- 

 ria Partlienium, and Chenopodium olidum. Aiaarantlius Blitum was found 

 last year on waste ground near the prison. The Balham end of the common 

 affords several interesting species ; Radiola millegrana is very abundant 

 almost close to the ydlmg^^wiih. Gar duus pratensis. Trifolium hyhridum,Medi- 

 cago sativa, Melilotus vulgaris, and Vicia tetrasperma, are well established 

 here, with the variety of T. pratense known as /3 parviflorum. Fmniculum 

 vulgare and Anthriscus Cerefolium occur on waste ground, and near the 

 railway. Reseda lutea. Actinocarpus Damasonium is still to be found in one 

 of the little gravelly streams near the road, opposite the Balham end. 



Wimbledon Common is of greater extent than the preceding, and the 

 botanist may here enjoy sweet country air, and a profitable afternoon's bota- 

 nising. At the entrance to Putney Heath, Barharea p>rmcoXy and Marruhium 

 vulgare may be found, the former well established. Scattered over the 

 common are Cuscuta EpitJiymum (upon the Heath and Thyme in several 

 places), Jasione montana, Filago minima, Orohus tuberosus, Scutellaria minor, 

 Carduus pratensis, Serratula tinctoria, Solidago Virgaurea, and Stachys 

 Betonica. I^ear the grounds of the Chelsea Waterworks, Epilohium angus- 

 tifolium occurs, evidently an escape from cultivation. On the almost bare 

 ground near the Windmill, I found, in the spring, Mmncliia erecta, Myosotis 

 collina, and M. versicolor ; and the adjoining ravine near the butts still fur- 

 nishes Lotus major, Melampyrum pratense, and Menyanthes trifoliata. At 

 the end of the butts furthest from the Windmill, I find Lysimacliia nemorum, 

 Calamintha Clinopodium, Erythrcea Centaurium, and Teucrium Scorodonia. 

 At some little distance beyond the Windndll, on the bank surrounding a 

 house, Lactuca muralis is found sparingly ; this, near London, is a scarce 

 plant ; and, further on still, upon waste ground, Marruhium vulgare and 

 Datura Stramonium are abundant. Alisma ranunculoides occurs by an 

 adjoining pond. On the part of the Common nearest Roehampton are Trifo- 

 lium striatum, T. suhterraneum, and Trigonella ornitliopodiodes, all in plenty,
