smaller, more acutely and deeply dentate, more erect and more shining 

 than in E. nemorusa ; leaves subtending the principal brandies 

 largest, 6-8 mm. long; bracts 5-6 mm. long, the upper with tri- 

 angular, lanceolate or subulate aristate teeth. Calyx-teeth and veins 

 often purplish or blackish. Corolla brightly coloured, 7-10 mm. 

 long ; tube elongated after the Howering, but in small-flowered plants 

 not conspicuously so. Leaves, bracts and calyx apjjearing glabrous, 

 but rather rough w^itli very minute seta?. Wetts. Mon. t. ix. fig. 10;

Small-flowered plants are sometimes distinguished with difficulty 

 from E. nemorosa, and, on the other hand, large-tlowered forms of 

 that species simulate E. Eerneri. There are also forms which appear 

 to be intermediates or hybrids between the two sj)ecies. 



Enola^d. — Devox. Near Plympton, Sej^t. 1902. Stem attaining 

 16 cm. high, with longer internodes and therefore less compactly 

 branched than usual. — N. Somerset. Kowberrow Down, Mendip, on 

 boggy ground, Sept. 1900, 1901, 190S and 1916. Concerning the 

 specimens gathered on Sept. 15th, 1900, which were in bad condition 

 on account of the lateness in the season and from having been bitten 

 by rabbits, Townsend wrote : " 1 can only put this to E. Kerneri, but 

 the remarkable diffuse branching, the branches compound and the 

 lower ones very slender render it remarkable. On carefully examining 

 the central stem, it will be seen that it has often been arrested from 

 grazing by cattle, causing growth and developments from the lower 

 leaves, but this does not seem in all cases to account for the unusual 

 development of branches. ... A specimen fi'om AV. H. Purchas from 

 Cheddar, Sej^t. 5, 1853, approaches tlie Black Down (Rowberrow) 

 form." 



Having observed this plant in succeeding years under more 

 favourable conditions, I can now state definitely that it is E. Kerneri. 

 As far as I have explored the locality it is sparing in quantity, 

 although other forms now to be mentioned are very abundant. The 

 most remarkable of these is a plant which Townsend named E. Levieri 

 Wetts. {E. citrta x RostJcoviana), but which I now feel com- 

 pelled to refer to X E. Recliingeri Wetts. {E. Kerneri x Eost- 

 kociana). 



The following is a description of this plant : — Stem 3-10 cm. high, 

 with numerous, crowded, compound branches often as long as the 

 stem ; internodes short, but longer in the taller plants with fewer 

 branches, which resemble E. EGsthoviana. Leaves and bracts ovate, 

 with ovate obtuse or triangular acute teeth, all, as well as the calyx, 

 pubescent with long or short hairs, and often with few or many long 

 glandular hairs. Corolla large, its tube elongating after the flowering, 

 brightly coloured. Capsule usually short and broad, rounded and 

 deeply emarginate at the top. 



Having had the o})portunity of thoroughly exploring the groimd 

 in the middle of June 1916, I found in a grassy lane which leads to 

 Kowberrow Down an abundant crop of young E. nemorosa and a few 

 plants of E. borealis, which, however, was more abundant in a neigh- 

 bouring valley. E. Kerneri, E. Rosytoviana and the hybrid plant 

 grew in the boggy valley, and the two latter also on the higher and
