16 SOUTH-EAST DEVON PLANTS. 



soil (the Ordnance Geological Chart is my authority) is carboni- 

 ferous, with greenstone cropping up here and there, limestone 

 occasionally to the south-east of Chudleigh, and granite above 

 Hennock ; while to the west of Bovey Tracey (a town beyond 

 Hennock, and five miles by road from Trusham) lie the "Bovey 

 Beds" (Lignites and Clays). This last-named district, known in 

 the neighbourhood as the Bovey Heathfield, is said to be rich in 

 interesting plants ; but I have as yet visited it only once, and that 

 so early as May. The semi-maritime character of the flora of 

 Trusham parish appears to me to be its most marked sj)ecial 

 feature, especially when it is remembered that the Haldons 

 intervene between the district and the sea. 



Eauinicuhis ])anijiorus, Linn. Exceedingly abundant on open 

 down and in stony field throughout the district, and quite a feature 

 in the flora — especially as the foliage keeps freshly green through 

 the greater part of the year. Also very common on the coast of 

 South-east Devon, near Sidmouth, at Budleigh Salterton, and on 

 Dawlish Warren. 



Cardamine imjmtiens, Linn. Li " Teign Lane," Trusham, 

 where it was discovered by Mr. T. E. Archer Briggs in May last, 

 while the plants were still only an inch or two high. Long known 

 by the Eev. H. Eoberts at Ashton, in a lane parallel to Teign 

 Lane, but from two to three miles to the north of it ; and on his 

 authority recorded for South Devon in ' Topogr. Bot.' In Teign 

 Lane this year it flowered freely, from the middle of June to the 

 end of September, along the dry bushy bank for a quarter of a 

 mile or more. 



Barharea intermedia, Boreau. In Trusham, Ashton, and 

 Christowe parishes ; rather frequent in waste spots and in rocky 

 ground, especially by the river Teign ; but never many plants 

 together. B. pracox, Brown, is often to be seen near it, but is 

 most abundant in the borders of stony fields. 



Teesdidia nudicaidis, Brown. Very common throughout the 

 district in bare rocky ground, and not infrequent in thin copses. 



Viola odorata, Linn, (with purple flowers). Very abundant at 

 the Chudleigh Piocks, but occurs nowhere else in the district, so 

 far as I have yet seen. The more common variety (b. alha of 

 Lond. Cat., ed. 7) is faMy general in woods and lanes. The lilac 

 form, which on chalk in Dorset and South Wilts I have always 

 found (without difficulty, though usually in small quantity) growing 

 with the purple and the white, seems quite absent here. The 

 Chudleigh Piocks are also remarkable for the great abundance of 

 V. Bciclu'uhacldana to be found there — almost to the exclusion 

 of the more general V. Blviniana ; the exact reverse of this 

 being true at Trusham, Ashton, and apparently elsewhere in the 

 district. 



Viola lactea, Sm. Common on the Bovey Heathfield, on 

 Knighton Heath (which is a continuation of Bovey Heath), and 

 on similar ground near. "With it, but (so far as I observed) only 

 on the drier and more strictly heathy spots, occurs a form which 

 I suppose to be the var. b. intermedia of 'Lond. Cat.,' ed. 7.
