Calochortus bruneaunis Nels.& Macbr. 



Bruneau mariposa 



DESCRIPTION: Bruneau mariposa lily has a single erect, 

 unbranched stem, 1-4 dm (4-16 in) tall arising from a bulb with a 

 papery coat. The long, linear, alternate leaves are rolled or u- 

 shaped in cross section. Foliage is glabrous. 1-4 flowers are 

 borne on erect stalks subtended by 2 or more linear bracts at the 

 top of the stem. Flowers have 3 pointed, egg-shaped petals, 25- 

 45 mm (1-2 in) long, that are nearly glabrous and white with a 

 vertical green stripe and a red or purple spot above the circular 

 gland near the yellowish base. The 3 sepals are narrowly lance- 

 shaped and shorter than the petals. The fruit is a narrowly 

 lance-shaped, 3-angled capsule, 35-55 mm (1-2 in) long. 



This species is similar to the more common C. nuttallii; however, 

 the latter has petals sparsely hairy near the base without a 

 vertical green line.
