Ipomopsis tenuituba, also known as slendertube skyrocket and slendertube ipomopsis, is a species of flowering plant in the phlox family Polemoniaceae. It is native to much of the western United States from California to Colorado, where it is found on rocky mountain slopes.
Description Ipomopsis tenuituba is a perennial herb producing an erect stem with widely spaced leaves, each 3 to 6 centimeters long and with many narrow, fingerlike lobes. The inflorescences toward the top of the stem each hold three to seven flowers. The flower is very pale to medium pink, sometimes with white streaks, or solid white. It is a tube 2 to 5 centimeters long, opening into a corolla of five twisting, pointed, ribbonlike lobes. The stamens and style do not protrude far from the mouth of the flower, if at all. While it is a perennial plant, it dies after its first flowering.
Taxonomy Ipomopsis tenuituba was first described as a species in the Gilia genus named Gilia tenuituba in 1913 by Per Axel Rydberg. In 1956 it was moved to Ipomopsis by Verne Grant, giving the species its accepted name. Along with the genus it is classified in the Polemoniaceae family and has two accepted subspecies.
