The genus Lerchea (Rubiaceae)
Blumea: Biodiversity, Evolution and Biogeography of Plants , Volume 32 - Issue 1 p. 91- 114
Lerchea Linn., a genus from Sumatra and Java, is revised. Eight species are recognized. Two new species, L. corymbosa and L. parviflora, are described. One variety has been raised to species, L. beccariana. A key, descriptions, illustrations, and distribution maps for all species are provided. Raphides are shown to be present in Lerchea and the two closely related genera Xanthophytum and Pomazota. Hence these three genera are transferred from Pomazotoideae-Pomazoteae to Rubioideae-Hedyotideae. Two cladograms are given, one of Lerchea, the other showing the relationship between Lerchea, Xanthophytum, and Pomazota.
