182 KENTISH BOTANY. [Juue, 



Cerasus avium grows in the hedge, and Hypericum humifusum 

 on the grassy borders of the road. 



At Littlebouru, Veronica Buxbaumii was well established. 

 This plant has now obtained a suflQcient settlement in the south 

 of England, although barely thirty years ago it was as great a 

 rarity as Arenaria balearica is at the present time, 1860. 



It would now be accounted sheer pedantry, or affected purism, 

 to refuse to enter this south European species in any list of our 

 spontaneous vegetable productions. 



Between Wingham and Ash, on the left-hand side of the road 

 from Canterbury, we were so fortunate as to light upon a large 

 colony of Geranium pyrenaicum, rivalling in size and beauty 

 those collected in the mountainous districts of the south of Eu- 

 rope, from which this fine and rare plant has obtained its name. 



This very gratifying discovery enlarged and rectified our 

 knowledge about the distribution of this species, which some be- 

 lieve to be a doubtful native. This plant has long been known as 

 a denizen of the valley of the Thames, above London, both on the 

 Surrey and Middlesex sides of the river. Its detection in the 

 south-east of Kent is, it is believed, recorded here for the first 

 time. 



Torilis infesta and Foeniculum vulgare are also entered in the 

 note-book made during this journey, and at this part of the 

 route. In the village of Ash, Sedum reflexum was very abundant 

 on roofs and walls ; and while on the subject of introduced plants, 

 it may be stated that Hypericum calycinmn, M. hircinum, Coro- 

 nilla Emerus, were pretty well established as plants which ap- 

 parently would establish themselves on a bank by the wayside, 

 contiguous to a shrubbery. 



After passing through Ash, we entered Sandwich marshes, 

 and in the deep ditches collected Utricularia vulgaris, Hyclro- 

 charis Morsus-rance, in flower. This fine floating species flowered 

 very sparingly during the past season. In these ditches Lenina 

 trisulca abounded, with Ceratophyllum demersum. Ranunculus 

 circinatus, Myriophyllum verticillatum, (Enanthe fistulosa, Typha 

 angustifolia, Scutellaria galericulata, and other more or less 

 common aquatic plants. 



At the entrance to Sandwich we turned aside to the left, to 

 visit the ancient ruined fortress of Richboro', the Roman Rutu- 

 pi^, and walked partly along the river-bank, and partly on the
