Valeriana dentata, Ehrh. Sm. Eng. Bot. No. 1370. 



Stem slender, rather firm, dichotomous usually only from above 

 the middle. Leaves oblanceolate-strapshaped, obtuse, entire, the 

 upper ones narrowly lanceolate-acute, generally toothed at the base. 

 Plowers not crowded, in small corymbose cymes, and also solitary 

 in most of the forks of the stem. Pruit ovate-lanceolate, ovoid, 

 not laterally compressed, acuminate, the fertile cell convex on the 

 back, but without spongy tissue and reticulating veins : the barren 

 cells not contiguous, reduced to small curved tubes on the face 

 of the seed, which appear as two elevated ribs enclosing a lyre- 

 shaped space. 



Calyx-limb accrescent in fruit, opaque, not netted-veined, much 

 shorter and narrower than the fruit, oblique, with a single large 

 tridentate or entire acute tooth over the fertile cell, and a few very 

 minute ones over the barren cells. 



In cultivated fields. Common, and generally distributed, 

 extending as far North as the counties of Moray, Forfar, and 

 Lanark. 



England, Scotland, Ireland. Annual. Summer 

 and Autumn. 



Very like Y. Auricula, but usually taller, the stem 9 inches to a 

 foot high. The flowers are of the same very pale-lilac, without 

 any blue tint ; but the fruit is very different, as the barren cells are 

 reduced to curved filiform tubes, and not parallel contiguous and 

 inflated, as in V. Auricula. The size and dentition of the calyx- 

 limb is very variable, but the length rarely exceeds half that of 

 the mature fruit. The hispid-i'ruited form, V. mixta (Duf.), 

 is common, and has been repeatedly mistaken for V. eriocarpa.
