Iva corbinii is a rare North American species of flowering plants in the family Asteraceae. It has been found only in Travis County in central Texas.[1] [2]
Iva corbinii appears related to the much more widespread I. axillaris but is considerably larger. It is a wind-pollinated perennial subshrub up to 200 cm (80 inches) tall with a large taproot. It has many oval leaves up to 7 cm (2.8 inches) long. Flowers are set in the axils of the leaves rather than congregated at the tips of branches as in related species. Each head can contain 7-13 florets.[1]
