Mirabilis austrotexana

B. L. Turner

Phytologia 75: 438, fig. 2. 1994.

Treatment appears in FNA Volume 4. Treatment on page 57. Mentioned on page 41.

Stems erect, few, moderately leafy mostly in proximal 2/3, few branched, 7–15 dm, glabrous basally, glabrous or sparsely glandular-puberulent distally. Leaves ascending at 30–70°, progressively reduced toward inflorescence; petiole 0.3–2 cm; blade green, lanceolate to lanceovate, 3–12 × 1–5 cm, thick and moderately succulent, base broadly obtuse to cuneate, apex acute or tapered to rounded tip, surfaces glabrous or sparsely pubescent. Inflorescences terminal and in upper axils, open, widely branched from main axis; peduncle 5–10 mm, glabrate or sparsely puberulent or spreading viscid-villous, crosswalls of hairs pale; involucres pale green, widely bell-shaped, 4–5 mm in flower, 7–10 mm in fruit, glabrous (except, often, margins) or very sparsely puberulent or villous, 70–80% connate, lobes broadly ovate, rounded. Flowers 3 per involucre; perianth pink to reddish purple, rarely white, 0.8–1 cm. Fruits brown to grayish or purplish brown, narrowly obovate, 4–5.3 mm, very sparsely pubescent with hairs 0.1–0.5 mm; ribs round-angular, 0.3 times width of sulci, 0.5–1 times as wide as high, smooth on angle, usually rugose on sides, occasionally interrupted and tuberculate; sulci with low tubercules, often also with transverse wrinkles.


Phenology: Flowering primarily spring–fall, occasionally winter.
Habitat: Mudflats, sandy or loamy soils
Elevation: 0-300 m

Discussion

Mirabilis austrotexana is very closely related to, and perhaps only a southern race of, the M. carletonii phase of M. glabra.
