Draba rectifructa by Teresa Burkert

General description: Draba rectifructa is an annual, with simple stems, 0.5-4  dm tall, and yellow flowers, fading to white. Petal and sepals are about 2 mm long. Plants are pubescent with simple and 2-4 rayed trichomes.  Plants have basal and cauline leaves, which are about 1-2 cm long. Fruits are about 7 mm long, pubescent, lanceolate and flattened (Flora of North America 2010, pers. comm. Burkert 2012).

Look Alikes: Draba rectifructa is similar to D. nemorosa in pubescence of stems and leaves, and like D. stenoloba var. nana (=D. albertina) in the tendency to have a small but well-developed rosette (Goodrich and Neese 1986).

Phenology: Flowering April-August throughout its range (FNA 1993+, Colorado Natural Heritage Program 2012).
