Carlowrightia parviflora (Buckl.) Wassh.

PHENOLOGY.— Flowering: January–February, July–December; fruiting: July–December.

DISTRIBUTION.— USA (Tex.), Mexico (Ags., Coah., Dur., Gto., Hgo., N.L., Qro., S.L.P., Tamps.).

HABITAT.— Thornscrub, sometimes on limestone.

NOTES.— Daniel (1983a) and Daniel and Acosta C. (2003) provided descriptions of this species ( Fig. 1G ). Plants with narrow, linear (vs. lanceolate to ovate) leaves, have sometimes been referred to C. lindauiana Standl. , but are not currently recognized as a distinct taxon; both “leaf forms” occur in Tamaulipas. A white-flowered form of the species ( Fig. 1J ) is uncommon in portions of its geographic range, including Tamaulipas.
