Pectis punctata Jacq., Enum. Syst. Pl. : 28 (1760). Type: Plum. ic. 86. f. 1. Note: Keil (1978: 139) cited Lectotype: Select. Stirp. Am. Hist. t. 128. 1763. with the footnote Authentic type specimens have not been located. Stafleu (1967) indicated that few of Jacquins West Indian material are known to exist, and that Jacquins 1760 publication represents a prodromus for his larger illustrated work. The illustration of Pectis punctata from the latter publication is selected here as the lectotype. This is unacceptable, since the only original material mentioned by Jacquin was the illustration in Plumiers work.
