The character states pertinent to the indumentum of Lobostemon Lehm. leaves are tabulated and discussed. Lobostemon possesses similar trichome and indumentum types as described for Echium L.. with the exception of the ‘Alpine’ indumentum type. Due to the environmentally induced variation, the leaf indumentum characters of Lobostemon are viewed to be of limited phylogenetic value, although they do diagnose a number of taxa.
