    • n draba A genus of cruciferous plants, low herbaceous perennials, or rarely annuals, often cespitose, distinguished by ovate or oblong many-seeded pods with flat nerveless valves parallel to the broad septum. There are about 100 species, mostly natives of the colder and mountainous regions of the northern hemisphere, of which 30 are found in North America, chiefly in the western ranges of mountains and in arctic regions. The whitlow-grass of Europe, D. verna, also introduced into some parts of the United States, is a small winter annual and one of the earliest spring flowers.
