Contents

It is native to the mountains of southern California and Baja California, where it grows in several local habitat types, including chaparral and woodland.

Description

Keckiella ternata is a shrub often exceeding two meters in height and spreading slightly with wand-like, waxy branches.

The branches bear whorls of three leaves each, or oppositely arranged pairs of leaves. Each toothed, curving leaf is tapered at the base and pointed at the tip, oblong to lance-shaped, and up to 6 centimeters long.

The inflorescence is an array of solid red tubular flowers up to 3 centimeters long. The hairy staminode is visible in the mouth of the flower.

Taxonomy

Keckiella ternata was scientifically described in 1859 by Asa Gray, who credited work by John Torrey, and named Penstemon ternatus. [3] [2] It was moved to the genus Keckiella in 1967 by Richard Myron Straw. Together with its genus it is classified in the Plantaginaceae family and it has two accepted varieties. [2]

It has seven homotypic synonyms of the species and one of its varieties. [2] [4]
