Asclepias curassavica Linnaeus, Species Plantarum 1: 215. 1753.

"Habitat in Curassao." RCN: 1777.

Lectotype (Woodson in Ann. Missouri Bot. Gard. 41: 59. 1954): Herb. Linn. No. 310.19 (LINN).

Current name: Asclepias curassavica L. (Asclepiadaceae).

Note: Rendle (in Proc. Linn. Soc. London 148: 64. 1935) clearly treated material in LINN as the type, noting that the description "...corresponds to the specimen, a poor one with a simple umbel". This fails, however, to distinguish between 310.18 and 310.19, which do not appear to be part of a single gathering (so Art. 9.15 does not apply). Wijnands (Bot. Commelins: 48. 1983) and others concluded that Rendle intended 310.18 (LINN) as the type, and accepted him as having typified the name. However, this does not seem justified, and Woodson appears to have been the first to make an explicit type choice (of 310.19).
