Rather pretty, with a slender stem about a foot tall, smooth, bluish-green leaves, and flowers about three-quarters of an inch across; the calyx much inflated, yellowish-white and papery, with brownish veins, and the petals cream-color, with two lobes and a "crown."

There are a few kinds of Vaccaria, of Europe and Asia, smooth annuals, with clasping leaves and red or pink flowers in terminal clusters; calyx five-angled and inflated in fruit, five-toothed, without bracts; petals longer than the calyx, without appendages; stamens ten; styles two. Both the Latin and common names allude to the value of some kinds for fodder.
