below; secondary nerves about 13 on each side, oblique, slender, 

 connected by gently curved arches, 1-U lin. distant from tlie margin,' 

 like the loosely reticulating veins faintly" raised ; petiole 4-5 i lin. long! 

 Flowers in dense subsessile corymbs, at the end of the branches and 

 from the axils of the uppermost leaf pairs, the terminal up to 12- 

 flowered, minutely rusty tomentose all over ; bracts ovate, more or less 

 obtuse, 1 lin. long; pedicels stout, up to U lin. long, bracteolate. 

 Calyx 1^-1 J lin. long, segments very broad, ovate, obtuse. Corolla- 

 bud up to 6 lin. long ; tube 2 lin. long, widest between the middle and 

 the mouth, finely pubescent without above the glabrous base, very 

 sparingly within ; lobes linear-oblong, up to 4 lin. long, sparingly 

 pubescent near the base without. Stamens inserted at the middle or 

 just above it ; anthers lanceolate, almost 1 lin. long. Ovary ovoid, with 

 a densely white-silky top. Style and stigma 1 lin. long, the latter 

 cylindric, deeply bifid.

Evidently nearly allied to L. owarierifiis and L. Klainei, but easily recognised 

 by the niuoh larger flowers. This yields, acein-ding to Dawe, excellent rubber. 



196. Landolphia Pierrei, Uua in Compt. Rend. Acad, Paris, 

 cxxxv. (1902) 8G8. Flowering branches robust, covered when young 

 with long reddish -brown hairs, at l^gth glabrescent. Leaves more or less 

 elliptic, long acuminate, rounded or almost sinuate at the base, 4-0 in 

 long, 2-1 J in. broad, midrib hairy; secondary nerves about 12 on each 

 side, rather conspicuous. Panicle corymbose, almost sessile at the end of 

 the branches or in branch-forks, dense, hairy ; bracts subacute, persis- 

 tent ; pedicels extremely short. Sepals oblong or ovate. Corolla-tube 

 fusiform, finely pubescent in the exserted part ; limb 3-4 lin. in diam. ; 

 lobes falciform, subacute, about half as long as the exserted part of the 

 corolla-tube. Stamens inserted at the middle of the tube ; filaments 

 hairy at the base ; anthers emarginate at the apex. Ovary tubinate, 

 glabrous below, velvety above ; stigma as in L. owariensis. Fruit sub- 

 globose, almost 2 J in. long, 2 in. wide, deep yellow, turning black when 

 dry and covering itself with a blueish bloom, smooth. Seeds about 12, 

 irregular, angular, 7i-10 lin. Ipng. — L. owariensis, Hallier f. Kaut-
