218 THE VALERIAN FAMILY. [Valerianella, 
cymes at the end of the branches or solitary in the forks. Calyx 
border small, entire or toothed, sometimes enlarging as the fruit 
ripens, but not feathery. Corolla with a short tube, not spurred at the 
base, and 5 equal, spreading lobes. Fruit small, convex on the back, 
but often marked in front with 2 longitudinal ribs or variously shaped 
projections, which are in fact either imperfect or abortive empty cells. 
_ The species are rather numerous, all much alike in general appear- 
ance, and distinguished chiefly by modifications in the form of the 
little fruits which appear to be constant. They are chiefly natives of 
the Mediterranean and Caucasian regions, but some are spread as 
weeds of cultivation over the greater part of the temperate regions 
of the northern hemisphere. 
Fruit without any perceptible projecting border on the top. 
Fruit as broad as long, somewhat laterally compressed, with a 
slight furrow on each side _. ‘ ‘ ; : : : : 
Fruit ovoid, convex on the back, with an oval, concave, or cup-

Fruit crowned by the small, oblique, tooth-like border of the calyx.

Fruit broadly ovoid, showing ‘when cut across 3 cells, 1 with 
a seed in it, and 2 conspicuous empty ones V. auricula.

1. V. olitoria, Poll. (fig. 488). Cornsalad, Lamb’s-lettuce.—A glabrous 
or slightly downy annual, seldom above 6 inches high, erect or ascend- 
ing, branching from the base, and repeatedly forked. Radical leaves in 
a spreading tuft, oblong, 14 to 2 inches long, rounded at the top, entire 
or with a very few coarse teeth, narrowed at the base; stem-leaves 
narrower, but with a broad base, often clasping the stem, and more 
frequently toothed. Flowers very small, mostly in little, dense, terminal 
cymes, + to 4 inch in diameter, surrounded by small lanceolate or linear 
bracts. Fruit about a line long and at least as broad, somewhat com- 
pressed, without any perceptible calycine border, and marked on each 
side with a longitudinal furrow. When cut across, the seed is seen in 
the centre, with a corky mass on one side, and an empty cell on the 
other. 
A native of southern Europe, often cultivated for salad, and now a 
common weed in waste places and cornfields in central Europe. Not 
unfrequent in various parts of the British Isles. Fl. spring and summer. 
2. V. carinata, Lois. (fig. 489). Keeled C.—Closely resembles V. 
olitoria in everything but the fruit, which is ovoid, not compressed 
laterally, but rather from front to back, without any corky mass at the 
back of the seed, and the empty cell in front is not closed in, but open, 
in the shape of a little cup-shaped appendage. 
More abundant than V. olitoria in most parts of continental Europe, 
but much less frequent in England. I have not met with it in cultiva- 
tion, although:so similar in foliage. Fl. spring and summer. 
3. V. Auricula, DC. (fig. 490). Sharp-fruited C.—Stems generally 
more erect than in the last two species, the branches not proceeding 
from so near the base, more slender and wiry; the leaves small and 
narrow, the cymes small and not so compact, often with single flowers — 
in the forks of the stem, and the bracts small and narrow. Fruit 
broadly ovoid, scarcely compressed, crowned by the little green oblique —
