Lackeya
Species 1.
Lackeya is closely allied with Dioclea Kunth and Galactia and has been treated historically by different authors as part of one or the other (C. T. Mohr 1901; R. H. Maxwell 1979). The woody stem habit and caducous stipules of Lackeya can be used to distinguish it from climbing members of Galactia, which have herbaceous stems and persistent stipules. Within Dioclea, species of sect. Macrocarpon Amshoff are more closely aligned morphologically with Lackeya. These species of Dioclea have larger, strongly compressed fruits with a woody pericarp, which differ from the smaller, less compressed fruit with a herbaceous pericarp found in Lackeya. Dioclea is more tropically distributed; its range does not overlap with that of Lackeya (R. H. Fortunato et al. 1996).
