3. Stenandrium bracteosum (Britton & Millsp.) Britton ex Leonard, Wrightia 2:77. 1960. Gerardia bracteosa Britton & Millsp., Bahama Fl. 402. 1920. TYPE.— BAHAMAS. Mayaguana: Abraham Bay and vicinity, in cultivated field, 6-8 Dec 1907, Wilson 7472 (holotype: NY [00114975]; isotypes ᘥ!, US). Figure 4E.

DISCUSSION.— Stenandrium bracteosum is endemic to the Bahamas. It was distinguished from S. droseroides by its stout peduncle (vs. delicately slender), longer bracts (8–12 vs. 3–7 mm), and pink (vs. white) corolla with a longer tube (7+ vs. 3–4 mm) (Correll and Correll 1982). The type specimen of S. bracteosum at NY is recognized as the holotype because the handwritten word “type” on its label resembles Britton’s handwriting. The specimen at US bears the note “fragment of type.”
