Description

Zornia sinaloensis Mohlenbr., Webbia 16 (1): 49. 1961.

Fig. S4

Type: MEXICO. Sinaloa: Santa Lucia, east of Panuco, 28 August 1935, F.W. Pennell 0037 (holotype US –00001989!; isotype GH–00063392!).

Shrub to ca. 30 cm tall. Stems erect, branched, glabrous. Leaves with 2 leaflets, petiolate. Leaflets 10–18 × 1–1.5 mm, linear, glabrous. Stipules linear, 1 veined. Inflorescences spiciform, terminal, 5 cm long. Bracteoles 8–10 × 4–5 mm, ovate, 2–3 veined, punctate, glabrous, green. Loment with 4–5 articles; articles 2 × 2 mm, not reticulate-veined, bristle-like trichomes absent.

Distribution and habitat: Mexico, endemic. It occurs in Tropical Dry Forest.

Conservation Status: Data Deficient (DD). Zornia sinaloensis is currently known from only three localities in Mexico. The limited information available on the population sizes and their distribution means that it is not possible to accurately assess the level of threat facing this species (EOO= 4,681.322 km ²; AOO= 12.000 km ²).

Notes: Zornia sinaloensis is recognized by its linear leaflets and stipules, with ovate bracteoles, and by its loment which lacks bristle-like trichomes.

Representative specimen examined: MEXICO: Sinaloa: Santa Lucia, east of Panuco, 28 August 1935, F.W. Pennell 0037 (US).
