370 FLORA OF OXFORDSHIRE. 
Its Flora is only imperfectly known, Oxford having 150 species not 
recorded for that division. 
Warwickshire has 85 species not recorded for Oxon. There are very 
great doubts as to the correct identity of Draba inflata and Lamium 
intermedium. Impatiens, Prunus Padus, Circea alpina, Dryopteris were 
probably planted. Hypocheris glabra, Elatine, Carex Beninghaus. C. 
stricta, Hquisetum hyemale are extinct, and Silene nutans, Medicago den- 
ticulata, Apera Spica Venti are casuals, leaving 72 species, of which 12 are 
Rubi, unrecorded for Oxon. The plants found in Warwick alone of the 
border counties are Barbarea arcuata, Cardamine impatiens, Stellariu 
umbrosa, Schleranthus perennis, Geranium sylvaticum, Arctium nemorosum, 
Crepis paludosa, Campanala patula. Vace. Oxycoccus, V. Vitis Idei, Scroph. 
Erharti, Empetrum, Salix acuminata, 8. laurina, Sparganum minimum, 
Crocus nudiflorus, Juncus Gerardi, Scirpus glaucus, Carex Erhartiana, C. 
elongata, C. distans, and Gastridium. 
Oxford has 88 species not recorded for Warwick. 
Northamptonshire has on record 41 species not recorded for or extinct 
in Oxon. Of these 12, Drosera, Linum perenne, Genista anglica, Comarum, 
Hypocheris glabra, Ajuga Chamepitys, Stratiotes, Osmunda, Thelypteris, 
Pilularia, Cladiwm, are extinet. Silene nutans, Sagina subulata, Scleran- 
thus perennis, Potamogeton heterophyllus are either extinct or were 
erroneously recorded. Centaurea Calcitrapa, Eryngium campestre, and 
Myriophyllum alterniflorum require recent confirmation. Of the 22 species 
known to occur Hypocheris maculata, Melampyrum cristatum, Urtica 
pilulifera, Aceras, Melica nutans, Sclerochloa distans, Tolypella intricata 
are not on certain record for any other of the border counties. 
Oxford has about 110 species not recorded for Northants.
