294 FLORA OF THE EXTREME SOUTH OF DEVON. 



S. rupestris, Lebel. Bolt Head, &c. The common species of 

 the rocky coast iu Devon and Cornwall. 



Polycarpon tetraphyllum, Linn. In considerable quantity and 

 for some yards below a w^all and on a rocky bank at Buckland, a 

 hamlet situated at the end of a small tidal inlet from the Avon 

 estuary, in the parish of Thurlestone. In one spot it occurs with 

 Erodium maritimum and Malva rotundifulia. The four places in 

 which I have seen this in Devon and Cornwall are all in villages or 

 hamlets, yet there is no ground for supposing it an introduction. 

 One reason for its choosing such spots may be that it will only 

 flourish in such dry or rocky places as support a scanty or minute 

 vegetation incapable of crowding it out. 



Malva moschata, Linn. Seen near Ford only. 



M. rotundlfolia, Linn. Prawle village ; Buckland. One of the 

 species most prone to grow near houses. 



Geranium sam/uineum, Lnin. On the mica and gneiss formation 

 very near Prawle Point. It is recorded by Keys from Bolt Head, 

 but we did not see it there. 



G. striatum, Linn. Seemingly quite established (as it is in 

 several spots around Plymouth) on a hedgebank a short distance 

 from an old house at CoUapit, on the lower road from.Kingsbridge 

 to Salcombe. 



G. rotundifoHiim, Linn. By the road to Loddiswell, immediately 

 to the north of Kingsbridge ; not seen elsewhere. G. lucidum in 

 the same locality. 



Erodium maritimum, Sm. Thurlestone and Bantham villages. 

 This dehghts to grow on rocky cuttings about villages lying near 

 the coast. Considering the proximity of the sea and the large 

 influx of tidal water into the tract I was surprised to find this in so 

 few spots ; the aUied E. cicutarium only at Thurlestone and Bantham ; 

 and E. moschatum not at all. 



Medicago sativa, Linn. Quite established in considerable 

 quantity on the edge of a piece of cultivated ground, near a mass 

 of rock, a short distance from Prawle Point, associated with 

 Geranium sanguineum, and other native plants. It must have grown 

 here for a considerable time. 



M. denticulata, Willd. By the road-side close to North Sands, 

 near Salcombe. 



Trifolium medium, Linn. Near Prawle, in the mica and gneiss 

 tract. Apparently not common. 



T. fragiferum , Linn. Thurlestone, on the sands and in the turf 

 between that and the village, in plenty. A considerable distance 

 from any previously recorded station. Not found anywhere near 

 Plymouth. 



Lotus tenuis, Kit. Near Bolt Head. 



Orohus tuherosus, Linn., b. tenuif alius. With the type, in a lane 

 near Wolston. 



Prunus Cerasus, Linn. In many spots in hedges. 



Agrimonia odorata, Mill. Between West Alvington and Marl- 

 borough ; also near Heddiswell Cross, a little west of the former 

 village; between Frogmoor and Ford. In the 'British Flora,'
