NOTES

There are five specimens in PC that have label information matching the type citation in Renauld’s (1891) protologue of L. diversifolium . Four of these (PC0105493, PC0105495, PC0105496 and PC0105497) are marked as specimens from Renauld’s personal herbarium and have labels in his handwriting. One specimen (PC0105492) is from Cardot’s personal herbarium, but otherwise identical to the others. Among these collections is a large specimen from Renauld’s herbarium that was annotated in 2007 as the holotype by Vaz-Imbassahy & Costa. It is selected as the lectotype.
