Based on Breweria minima A.Gray

Description.

Annual with adventious root; stems 5-25 cm long from central rootstock, decumbent, indumentum of scattered long hairs mixed with some shorter pubescence. Leaves 1-5 × 0.2-0.6 cm, oblong-oblanceolate; apex rounded; base attenuate, petiole-like, margin entire. Flowers solitary, axilary; peduncles 0.8-1.6 cm, often becoming recurved in fruit; bracteoles 3-6 (-9) × 1-2 mm, oblanceolate; pedicels 1-3 mm; outer sepals 5 × 1 mm, lanceolate-oblong, acute to apiculate, differing from the oblong-obovate inner sepals; corolla 5-6 mm long, deeply lobed, pale blue with white midpetaline bands radiating from the centre; midpetaline bands glabrous, terminating in a mucro; filaments eglandular; ovary glabrous; style glabrous, divided 1-1.5 mm above base, stigmas 1 mm. Capsule glabrous; seeds tuberculate.

Distribution.

United States of America: California (Greene 1665, Pringle s.n. [6/4/1882]), Arizona (fide Austin 2006: 79); Mexico: Baja California (Raven et al. 12670).

Notes.

Although separated geographically from related species, Convolvulus simulans is very close to Convolvulus pentapetaloides and its allies morphologically and this is confirmed by our molecular studies which show they all belong to a single clade ( Williams et al. 2014).
