Lectotypification of the Names of Linnaean Echium Species Now in Lobostemon (Boraginaceae)

The first species of Lobostemon Lehm. to be collected in South Africa were originally considered to belong to Echium L. Although Lobostemon was established by Lehmann (1830), it was Buek (1837) who placed the three Linnaean species in Lobostemon. To date their names have not been typified. A visit to herbaria (BM, L, LINN, S, UPS) housing possible Linnaean material was undertaken to account for all potential type material.
