Stanleya pinnata var. texana

B. L. Turner

Lundellia 7: 39, figs. 2, 3. 2004.

Treatment appears in FNA Volume 7. Treatment on page 698. Mentioned on page 697.

Cauline leaves: blade linear-lanceolate, margins entire. Flowers: sepals 8–10 mm; petals 8–9 (–10) mm, claw 4–5 mm; gynophore 10–20 mm, glabrous or nearly so. Fruits 5–8 cm; ovules 10–20 per ovary. Seeds 2–3 mm.


Phenology: Flowering Apr–Jun.
Habitat: Silty flats, desert washes, bare calcareous-gypseous outcrops, betonite clay hills

Discussion

Of conservation concern.

R. C. Rollins (1939c, 1993) treated plants of var. texana under both var. integrifolia and var. pinnata. As shown by Turner, var. texana is somewhat distinct morphologically and is disjunct by ca. 800 km from the nearest populations of var. pinnata. Also, it grows on gypseous instead of seleniferous soils. It is found only in Brewster County.
