118 THE FLORA OF HARROW AND ITS VICINITY. [April, 



in the neighbourliood may be noticed the yellow Fumitory, Cory- 

 dalis lutea, which occurs on old walls at Miss HilPs, above the 

 Cricket Ground, and in a few other places. This, though well 

 established in its present habitat, was most likely introduced as 

 a garden flower. The Grass Vetch, Lathyrus NissoUa ; the vil- 

 lous Rose, Rosa villosa, a native of the northern counties, but 

 apparently indigenous in a field near the railway station at 

 Greenhill. Parsley, Petroselinum sativum, on old garden walls 

 in the rear of houses in Crown Street. Bastard Stone Parsley, 

 Sison Amomum, and Pepper Saxifrage, SiJaus pratensis, occur 

 plentifully : though in the more northern parts of Great Britain 

 they are comparatively rare. The common parsnip, Pastinaca 

 sativa, a chalk plant, is found sparingly. The Salsafy, Tragopogon 

 porrifoUus, is found in several spots in the neighbourhood of 

 Greenhill and Kenton. The Ox-tongue, Helminthia echioides, is 

 tolerably frequent by the waysides. The hairy Thrincia, Thriacia 

 hirta, is common in pastures, and especially in the Cricket Ground, 

 the south end of which is in summer studded with its bright star- 

 like flowers. The acrid Lettuce, Lactuca virosa, a poisonous plant 

 of unfrequent occurrence, is very plentiful in some parts of the 

 neighbourhood, especially in the Greenford Lane and Pinner 

 road. The Mountain Speedwell, Veronica montana, is abundant 

 in Harrow Park. Buxbaum's Speedwell, Veronica Buxbaumii, is 

 found sparingly near Perivale. The great Snapdragon, Antir- 

 rhinum majus, is very abundant on the garden wall at the Grove. 

 Vervain, Verbena officinalis, may be found near the canal bridge 

 in the Greenford road. The narrow-leaved Islvai, Mentha pra- 

 tensis, grows on the roadside leading to Pinner. Archangel, 

 Lamium Galeobdolon, occurs on the hedge-bank in Horsington 

 Lane. The Oxlip, Prhnida elatior, is occasionally found in the 

 meadowsc The hoary Plantain, Plantago media, is to be found 

 in the pastures near the canal at Greenford. The fig-leaved and 

 oak-leaved Goosefoot, Chenopodium ficifoUum and glaucum, occur 

 in a farmyard near Kenton. Caper Spurge, Euphorbia Lathyris, 

 springs spontaneously in gardens about Roxeth. Wood Spurge, 

 Euphorbia amygdaloides, occurs on hedge-banks in Horsington 

 Lane, and near the footpath leading from Roxeth to Pinner Lane. 

 The Hornbeam, Carpinus Betidus, is not unfrequent, but only in 

 places which render its claim to spontaneous growth questionable. 

 The same may be said of the Abele, Populus alba. Harrow is
