General information
Laphamia specicola is known from Grand and San Juan Counties, Utah where it grows only in the Navajo Basin along the Colorado and San Juan Rivers. This species is often associated with desert shrub and hanging garden communities and grows on sandstone and limestone formations such as cliff basses, alcoves and narrow canyons. Alcove Rock-Daisy is named for its unique habitat and has tiny yellow flowers blooming in a humble display of small, packed florets. This plant is unique for having miniature leaves that are measured in the milimeters giving this very green species a slender form as it emerges through tangled stems of the previous years growth.
