is a delicate perennial forb in the purslane family (Portulacaceae) that grows (seemingly miraculously) in very steep, rocky scree slopes and slide-rock. Claytonia scammaniana
has beautiful five-petalled glossy pink flowers and grows 4-6 cm high, arising from a filiform rhizome
. Basal leaves are linear
, fleshy, with a hyaline sheath at the base. Stem leaves are opposite, sessile
and narrowly elliptical. The inflorescence
consists of 1 to 2 purplish to pink flowers with 5 petals and 2 sepals
. Fruits are a dry green capsule
, splitting along the seams to release seeds. The other pink-flowered member of the genus Claytonia
in Denali is Claytonia sarmentosa
, which is found in moister lush meadow habitats, has more basal leaves and generally broader leaves.
This species flowers in early summer in Denali.
with bisexual flowers. Flowers are insect pollinated, most likely by flies, bees or wasps. Seeds are flung out when capsules
split open. Seeds have a prominent elaiosome—a lipid-rich food-packet that attracts ants, who carry the seed to their nest, remove the elaiosome and leave the seed intact to germinate.
