Ninagongo: Oberer Wald in 2500 — 2800m Meereshohe, klimmender 

 Strauch mit rein\veil3en, nach Honig duftenden Bliiten (bliihend und fruchtend 

 am 4. Oktober 1907 — n. 1337). — Bugoyer Bambusmischwald: ca. 2500 m 

 u.M., Klimmstrauch, oft krautig erscheinend, Bliiten weiB, sehr stark nach 

 Honig duftend (bliihend und fruchtend am 31. Oktober 1907 — n. 1441). 



Diese Spezies ist sehr nahe mit V. pteropoda Oliv. et Hiern. verwandt, von 

 der sie aber sofort durch die klimmende Wuchsform zu unterscheiden ist.
