L. scabra, DC. (Echites scabra, Labill. Sert. Austr. Cal. t. 31; Thenardia scabra, Spr.), is confined to 
New Caledonia (Labiilardiére) and Eromanga, New Hebrides (M‘Gillivray!), and is the only species 
besides the following one as yet found in tropical Polynesia, unless a twining plant, of which I collected the 
leaves only, and distributed under n. 315, should prove a congener. It is a hairy plant, and certainly is not, 
as Asa Gray at one time suspected, identical with Z. levis.
