Thispublicatio n isa monographi c revision of thegenu sOncinoti s containing sevenspecies ,si xo fwhic h are restricted tocontinenta l Africa and onet o Mada gascar.Th estud y isbase d mainly onherbariu m material. Inadditio n the author has had the opportunity to study living plants of five species in the wild and undercultivatio n inbotanica lgarden si n Africa.
HISTORY OF THE GENUS
When BENTHAM (1849) described the genus Oncinotish e based it on a single species,O. nitida. Th enam eOncinotis i sderive d from the Latin 'uncus'(i nGree k 'OVKOQ'), 'uncinatus' meaning 'shaped like a hook, hooked', referring to the curvedtail so fth eanthers . Several authors added further species, some of which were later reduced to synonomy, while others have been referred to the closely related genusBaissea. Meanwhile a few specieswer eerroneousl y described in theclosel y related genus Motandra. In 1954 PICHON revised Oncinotisan d attributed 10specie s to it, 7 of which aremaintaine d here.
GEOGRAPHICAL DISTRIBUTION
The distribution of the genus is shown on Map A. Oncinotistenuiloba i s the mostwidel ydistribute d speciesreachin gfro m Western Nigeria to Eastern South Africa, O. glabrata, O. gracilisan d O.pontyi occur in West and Central Africa. Lesswidel y distributed species are:O. nitida,limite d to acomparitivel y narrow zone along the West African coast; O.hirta, restricted to Central Africa; and O. tomentella,endemi ci n Madagascar.
HABIT AND GROWTH
All Oncinotisspecie s are lianas or climbing shrubs. The present author has observed the architectural model of TROLL (HALLE & OLDEMAN 1970: 125; HALLE et al 1978:242 ) in the field for five species {O.glabrata, O.gracilis, O. nitida, O. pontyi and O. tenuiloba).Th e species wind either to the right or to theleft , orar eno t twining.
