- n thysanocarpus A genus of cruciferous plants, of the tribe Isatideæ. It is characterized by a small one-seeded winged silicle, often with a perforated margin, by accumbent cotyledons, and stamens without appendages. There are about 6 species, natives of California and Oregon. They are slender branching annuals, with pinnatifid radical leaves, and entire, clasping, and sagittate stem-leaves. The racemose white or violet flowers are followed by fiattened ovate or roundish pods hanging on filiform pedicels and resembling samaras. A variety of T. curvipes with perforated wing is known as lace-pod; and a fringed variety of T. laciniatus, as fringepod (which see).
