X. j:^fi/er5m7ia is evidently a very variable plant. It is doubtful if some of tl'ie 

 varieties admitted here represent more than individual or local states. On the other 

 hand, therj are indications of the existence of more or less distinct form.?, wliich will 

 have to be noticed in future. Tlie 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 witli almost pear-shaped fruits, solid at the base. Dr. Busse, 

 who collected it in Donde, proposed the name var. Tubeujii lor 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 hill- 

 sides of the Kande peninsula near Langenburg, Lake Nyasa. It was identified by 

 Hallier f. I.e. 81, with Rowland's specimen from Lagos described here as L.ferru- 

 ginea, and enumerated together with it as L. scandens, vsly . 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 typicdi. 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 J (rarely up to 3 J) 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 pedunoled, many-flowered, finely fulvo- 

 tomentose (rarely elongate, with distant spreading or recurved branches, 

 the lower acting as tendrils) ; peduncles |-lj in. long; bracts broad- 

 ovate, subacute or apiculate, early deciduous, like the very short pedicels 

 finely fulvo-tomentose. Calyx 1-1 J lin. long, finely f ulvo-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, flashy, lJ-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, 1-2J in. in diam., yellow mottled with red, wrinkled ; rind 

 woody, 2-2J lin. thick ; seeds 5-6 lin. long, — Lam. Illustr. iii. 582, t.
