 brilliant blue, in a short panicle ; capsules egg-shaped. Almost the 

 entire plant is glabrous. A rare species, found only on one or two 

 mountains in Scotland. Fl. July, August. Perennial. 



V. fruticidosa (Flesh-coloured Speedwell) is a variety of V. saxa- 

 tilis, with small pink flowers, and is extremely rare. 



3. V. Alpina (Alpine Veronica). A slightly hairy little plant, 

 with simple, ascending stems, 2-5 inches high (not woody), bearing

 blue veins. Capsules inversely heart-shaped, with a long style.

 trate stems, rooting at the nodes, varying from 2-6 inches in length :
