# Pallid Milkweed

*Asclepias cryptoceras subsp. cryptoceras* S. Watson

The Colorado Plateau plant, of juniper and pinyon-juniper country from Wyoming down into Arizona, with larger flowers than its western sibling.

## How to tell it apart

Larger in every flower part: corolla lobes 11 to 14 mm, crown segments 6 to 8 mm, and the crown tips stand above the central column. Flower clusters hold 4 to 10 flowers on long stalks.

## Where it grows

Fishbein notes that this plant looks remarkably like three unrelated species it grows alongside, including a milkvetch and a four-o’clock, and wonders aloud whether they form a mimicry complex. It is rare in Arizona and Nevada.

States: AZ, CO, NV, UT, WY
