description
Hunzikeria texana is a small, woody, perennial plant that can grow up to 20 cm high. It branches off from a woody base with slender but early woody twigs that are densely hairy with short, sticky trichomes . The leaf blades of the leaves are entire, inverted ovoid to inverted lanceolate or occasionally wedge-shaped. Usually they are 10 to 20 mm long and 5 to 8 mm wide. To the front they are usually pointed or occasionally blunt, the base is pointed or tapering to a point. The leaf veins can only be seen indistinctly. Fine hairs are mainly present on the underside, and the leaf margin and the leaf axis are also ciliate. The leaf stalks are usually 2 to 5 mm long.
The terminal or almost terminal flowers stand individually or in pairs on about 7 mm long, round pedicels . These are tomentose and are surrounded by normal-sized leaves. The calyx is inversely conical, ten-nerved and about 10 mm long, its entire surface is hairy tomentose. The calyx is set with five triangular tips about 3 mm long. The crown is saucer-shaped and colored light purple or purple-pink. The outside is hairy with shortened trichomes. The slender corolla tube is 15 to 25 mm long, about 0.5 mm wide and only slightly widened towards the top. The Kronschlund is widened mm to about 2, the dust bag to take. The coronet is slightly inclined to the corolla tube and measures 20 to 23 mm in diameter. It is divided up to about half into five corolla lobes, these are almost evenly rounded-butt-shaped. The four stamens start far below in the corolla tube, in the upper pair they are greatly shortened. Occasionally a thread-like staminodium is formed. The stylus has two wings just below the scar . The scar itself is divided into two crescent-shaped arms. It is located inside the corolla tube and is enclosed by the anthers.
When the fruit is ripe, the flower stalks do not enlarge, the calyx is only slightly enlarged. The calyx encloses the two-chamber capsule fruit . There are about five relatively large seeds in it . These are reddish, elongated, about 1.5 mm long and provided with about eight coarse, transverse, darker colored furrows.
Distribution and locations
The species was collected in Texas and the Mexican states of Chihuahua , Coahuila, and San Luis Potosí . The locations are mainly stony, calcareous slopes along the eastern side of the Edwards Plateau and the Sierra Madre Oriental .
