A few inches - forms low mats
Plains, hillsides, washes, usually sandy locations, over a wide elevation range; up to 12,000 feet
Linear, hairy, up to 0.6 inches long
Cryptantha circumscissa is a low growing species that forms small, flatted, rounded mats, typically 6 inches in diameter. The short (up to 3 inches), slender, branched stems are held at around a 45 degree angle, and are covered both by flattened strigose hairs and longer, bristly hairs. Leaves have a similar hair covering; they terminate in a spike and are slightly folded up along the midvein.
Flowers are produced in small, bracted clusters, of between one and five, and are attached by very short stalks. Flowers tend to point upwards. The calyces are bristly, similar in hairiness to the leaves. The appendages at the base of the corolla lobes are pale yellow, and less pronounced than for most other cryptantha species.
There are two varieties: the widespread var circumscissa has stems longer than one inch, and leaf edges often rolled underneath, while the less common var rosulata (a high elevation species) has stems of less than one inch, and flat leaf margins.
