Lagarinthus eustegioides Meyer (1837: 207) . Gomphocarpus eustegioides (E.Meyer) Dietrich (1840: 901) . Asclepias eustegioides (E.Meyer) Schlechter (1896b: 6) . Schizoglossum eustegioides (Meyer) Druce (1917: 645) . Type : — SOUTH AFRICA , Eastern Cape Province , Scattered in the Sneeuwberg Mountains, not far from Compasberg, alt. c. 1100 m , 2 March 1833, Drège 3438 ( lectotype P [P04256914] scan!, here designated; isolectotype K! [K000234579] fragment). Schizoglossum crassipes Moore (1902: 383) . Type : — SOUTH AFRICA , Leeuw Spruit and Orange River Colony, near Vredefort road, Capt. Hamilton-Barrett s.n. ( holotype BM! [BM000925946], isotype K! [K000234581], a branch from the type). In the original description of Lagarinthus eustegioides Meyer (1837) only one locality is listed. When this locality is cross-referenced with the collections listed in Drège (1843: 54–55) the only collection that matches the taxon and locality is Drège 3438 . As the specimen from P (only scan seen) is a more complete specimen when compared to the fragment at K, it is selected here as the lectotype .
