Notes

Hassler (1907: 12−13) described Polycarpon anomalum mainly on the basis of the occurrence of an elongate style with one stigma. This feature was considered as taxonomically good by Iamonico (2021) who decided to maintain Hassler’s taxon as separate species despite various authors synonymized it with P. suffruticosum.A

Description

Shrubs (chamaephyte) up to 50 cm tall, woody at the base, branched, branches usually finely ridged. Leaves in whorls of 4 (sometimes 6), sessile, lanceolate to lanceolate-linear, 3.5−4.0 × 15.0−40.0 mm, apex acute, base cuneate, glabrous to glabrescent. Inflorescence terminal, dichotomous cymes, 4(−6)-branched; bracts ovate, scarious. Flowers subsessile; sepals 5, ovate, (1.6−)1.9−2.5(−2.8) mm long, obtuse or acute, 1-nerved, keeled, hyaline on margins; petals 5, ovate, 1.3−1.5(−2.0) mm long, shorter than sepals, usually obtuse, entire, white; stamens 3, perigynous; style 1, stigma 1. Fruits (capsule) ovoid, 2.0−2.7(−3.0) × (3.0−)4.5−5.5 mm, longer than the calyx, opening by non-involute valves; seeds 20−30, ovoid-fusiform, nearly smooth on the surface or slightly reticulate, brown.B
