Notes
L. petersiana is evidently a very variable plant. It is doubtful if some of the varieties admitted here represent more than individual or local states. On the other hand, there are indications of the existence of more or less distinct forms, which will have to be noticed in future. The fruits of the specimens collected by Sir John Kirk on the Lower Zambesi are exactly globose; but farther north, in German East Africa, a form occurs with almost pear-shaped fruits, solid at the base. Dr. Busse, who collected it in Donde, proposed the name var. Tubeufii for it. Kirk's specimen at Kew from Bagamoyo and Stuhlmann's 6509 and 6657 at Berlin belong to it. Another conspicuous, but imperfectly known, form was collected by Goetze (884!) on the hillsides of the Kande peninsula near Langenburg, Lake Nyasa. It was identified by Hallier f. l.c. 81, with Rowland's specimen from Lagos described here as L. ferruginea, and enumerated together with it as L. scandens, var. ferruginea. The resemblance is very great, but the leaves are rather more ovate, more acutely acuminate, the flowers larger and the young fruits rusty-tomentose, though not so densely and delicately velvety as in typical L. petersiana .
