66 DIDYNAMIA— GYMNOSPERMIA. Ajuga. 



A. genevensis. Willi. 5 J 6. Scholler Barb. 135. 



Bugula caerulea alpina. Pluh. Almag. 73. t. 1 8./. 3. Ytaii Syn. 245. 



On mountains, rare. 



In Carnarvonshire. Ray. On the summit of a mountain, near 

 Castleton, Derbyshire. Mi: D. Turner, in the county of Dur- 

 ham. Mr. Robson. On the mountains of Aberdeenshire, not 

 uncommon. Mr. David Don. 



Perennial. July. 



This has no creeping scyons. The leaves are scarcely more hairy 

 than in the last, very coarsely and unequally toothed ; many of 

 the upper ones, and frequently a!I the floral leaves, ovate, and 

 quite entire ; the uppermost of all only slightly tinged with a 

 violet colour ; the radical leaves stalked and oblong, not much 

 larger than the rest. Fl. 10 or 12, sometimes more, in each 

 whorl. Cal. chiefly hairy about the teeth. Cor. pale blue, with 

 darker streaks ; middle segment of the lower lip undivided, 

 more or less acute, and various in breadth. I suspect that it is 

 often notched, or inversely heart-shaped, in which case the 

 plant becomes A. genevensis of Linnaeus and others ; and in this 

 state it is A. pyramidalis of Ehrhart's Herb n. 156. and of Bul- 

 liard, t 361. It is then also Bugula n. 283 of Haller, excluding 

 his variety rubrifolia ,• and B. montana of Rivinus, t. 76. f. 2. 

 Plukenet's figure in like manner has the middle lobe notched. 



3. A. pyramidalis. Pyramidal Bugle. 



Hairy. "Whorls crowded into a pyramidal form, many- 

 flowered. Radical leaves very large, obovate, crenate, 

 obtuse. Upper lip of the coi'olla deeply cloven.

Found in Scotland by the Rev. Dr. Burgess. Lightfoot. On Ben 

 Nevis, and in other places. Dr. Hope. On Tor Aichaltie, Ross- 

 shire. Mr. W. Gibb. 



Perennial. June. 



Of a more dense and pyramidal habit, as well as much more uni- 

 formly and copiously hairy than the last. Stem 4 or 5 inches 

 high, without runners. Radical leaves numerous, stalked, obo- 

 vate, 2 or 3^mches long, and half as broad, with numerous, 



■ shallow, rounded notches ; Jloral ones, or bracteas much smaller, 

 pale purple. Teeth of the calyx very hairy, longer than its tube. 

 Cor. light blueish purple, with dark streaks ; upper lip in 2 deep 

 acute lobes, by which this most distinct species is clearly mark- 

 ed. Seeds finely reticulated.
