Perennial. — Flowers from May to August. 



Root somewhat woody, spreading. Whole plant very smooth 

 aftd even. Stems a foot or more high, leafy, very smooth, and 

 rather glaucous. Leaves, as in all the species of this genus, op- 

 posite ; lower ones somewhat stalked, spear-shaped, entire, rather 

 succulent ; upper ones sessile, more egg-shaped, and occasionally 

 toothed at the broadest part. Flowers of a fine deep rose colour, 

 sometimes varying to a pale flesh colour, or white ; they are very 

 numerous, scentless, upright, forming a dense corymbose head, of 

 forked, unilateral spikes. Seed egg-shaped, narrowed upwards, a 

 little compressed, crowned by the sessile feathery down, or pappus, 

 (see fig. 4). 



The celebrated French Botanist, Professor Decandolle, has 

 separated this, and 2 or 3 exotic species, from Valeriana, and has, 

 with them, consituted a new genus which he has named Centrdn- 

 thus ; this genus differs from Valeriana only in the long spur at the 

 base of the tube, and in having 1 stamen instead of 3. 



Valeriana rubra, although apparently wild, and very abundant 

 in the chalk-pits in Kent, is considered to be originally the outcast 

 of gardens. — Dr. Withering observes, “ From the progress of 

 time and intercourse with foreign parts, so many exotics have be- 

 come naturalized in Britian, that it is scarcely possible to define what 

 may strictly be considered indigenous; and in the present state of 

 scientific research, were we rigidly to adhere to aborigines, exclud- 

 ing those plants which there is reason to suspect may have been 

 gradually propagated from gardens or other adventitious sources, 

 our catalogue would be deemed extremely incomplete. Valeriana 

 rubra, and V. pyrenaica are instances of these dubice, being more 

 properly natives of the south of Europe, yet not unfrequently grow- 

 ing wild with us.” Bot. Air. v. ii. p. 89, note.
