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, Z’ubeufii for it. Kirk’s specimen at 
Kew from Bagamoyo and Stullmann’s 6509 and 6657 at Berlin belong to it. Another 
conspicuous, but imperfectly known, form was collected by Goetze (884!) on the hill- 
sides 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. ferru- 
ginea, and enumerated together with it as LZ. scandens, var. ferruginea, The re- 
semblance 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 typic.l L. petersiana. 
19, L. owariensis, Beauv. Fl. Owar. i. 55, t. 34. A more or less 
scandent shrub or tree, often very large, with long hook-branched 
tendrils (usually more or less modified inflorescences) ; young branches 
scantily pubescent, soon glabrescent, dark brown to almost black, dotted 
with small yellowish lenticels. Leaves oblong, rarely elliptic or lanceolate, 
subacuminate or sometimes distinctly and abruptly acuminate (acumen 
obtuse), rarely quite obtuse, subobtuse or subacute at the base, 3-6 in. long, 
1-2} (rarely up to 34) in. broad, coriaceous, quite glabrous or finely pubes- 
cent in bud, glossy above ; midrib flat or slightly channelled above, promi- 
nent below ; secondary nerves 10—15 on each side, oblique, slender, con- 
nected by strongly curved zig-zag arches rather close to the margin, like 
the reticulating veins more or less raised; petiole 2-4 lin. long. Panicles 
pyramidal or ovoid, shortly peduncled, many-flowered, finely fulvo- 
tomentose (rarely elongate, with distant spreading or recurved branches, 
the lower acting as tendrils); peduncles 4-1} in. long; bracts broad- 
ovate, subacute or apiculate, early deciduous, like the very short pedicels 
finely fulvo-tomentose. Calyx 1-1} lin. long, finely fulvo-tomentose ; 
segments very broad, ovate to almost rotundate, acute or obtuse. 
Corolla white, soon turning brownish; tube cylindric, widest between 
the middle and mouth, 3 lin. long, more or less pubescent or tomentose 
without, at least in the upper half; lobes oblong, acute, spreading or 
reflexed, fleshy, 14-2} lin. long, rarely longer, pubescent without, 
mouth finely pubescent. Stamens in the upper third of the tube; 
anthers oblong, subobtuse. Ovary depressed, truncate, top finely 
tomentose. Style and stigma 2 lin. long, the latter conical, shortly 
bifid. Fruit of the shape, size and colour of a middle-sized or small 
orange, 1-21 in. in diam., yellow mottled with red, wrinkled ; rind 
woody, 2-21 lin. thick; seeds 5-6 lin, long.—Lam. Illustr. iii. 582, t.
