Aspidosperma refractum Mart. & Zucc., 1824

Aspidosperma refractum Mart. & Zucc. View in CoL in Flora 7(1, Beil. 4): 136. 1824.

≡ Macaglia refracta (Mart.) Kuntze, Rev. Gen. View in CoL 2: 416. 1891.

Lectotype (designated here): — BRAZIL. Bahia: Inter oppidum Caiteté et praedium Maracás , s.d., C.F.P. von Martius s.n. ( M [barcode M-0183484 image!]; isolectotypes: M [barcode M-0183483 image!, barcode M-0183485 image!, barcode M-0183486 image!, barcode M-0183487 image!, barcode M-0183488 image!]) .

Notes —The diagnosis of A. refractum presented in “ Flora ” by Martius & Zuccarini (1824) was based on a single collection made by Martius himself, though the indication of the original material ( Martius s.n.) was only made later by Martius (1824) in “ Nova Genera et Species Plantarum ”. Since this name was published without a holotype, we selected a specimen possessing a label including information about the collection place as the lectotype of A. refractum (M barcode M-0183484) (ICN article 9.3; Turland et al. 2018).

Woodson (1951) considered A. refractum as a synonym of A. pyrifolium Mart. & Zucc. , but Duarte (1970) reestablished the former. We agree with Duarte’s concept because A. refractum presents flowers with triangular calyx lobes ( vs. filiform), entirely tomentose ovary ( vs. glabrous), and sparsely lenticellate follicles ( vs. densely lenticellate) with conspicuous midrib ( vs. inconspicuous).
