The description of the inflorescences and flowers lias been drawn np from speci- 

 mens grown in the Tjikomo Gardens in Java (ScbifPner, Trop. Kultnr-u. Heilpfl. 

 No. 50!) These plants were bronglit to Java from Ceylon, where seeds had been 

 received from Kew. The Usambai*a specimens are imperfect, and their determina- 

 tion will have to be tested when flowering specimens come to hand. Vogtherr 

 also figures and describes fruits ; but they are evidently quite young, and his state- 

 ment that the seeds are exalbnminous is certainly erroneous. L. toatsoniana is very 

 closely allied to L. crassipes, Kadlk., of Madagascar and to L. Buchananii, Stapf, which 

 has large fruits and i-ather large seeds of the ordinary Landolphia type, and it has 

 no particular resemblance to Clitandra parvifolia, Stapf {Cylindropsis parvifolia, 

 Pierre, the type of the genus Cylindropsis). 



2. £a, kilimandjarica, Stapf. A scandent, perfectly glabrous 

 .shrub. Young branches slender, greyish-brown when dry; lenticels 

 not very conspicuous. Leaves oblong to broadly lanceolate, obtusely 

 subacuminate, subacute or slightly rounded at the base, 2-4 in. long, 

 1-1 J in. broad, thinly coriaceous or papery, glossy above, green on both 

 sides, but paler beneath; midrib channelled above, much raised below ; 

 lateral nerves about 15-18, subhorizontal, fine, faintly raised below; 

 reticulation delicate, but distinct below ; marginal arches rather close 

 to the margin ; petiole 1 J-2 lin. long. Flowers in terminal short 

 racemes, or small panicles ; peduncles very short or up to 1 in. long, 

 slender ; bracts ovate, subacute, membranous, J lin. long ; pedicels up 

 to 3 lin. long, horizontally spreading. Calyx scarcely 1 J lin. long, quite 

 glabrous ; sepals broad, ovate, obtuse or subacute, more or less mem- 

 branous. Corolla up to G lin. long in bud; tube 21 lin. long, slightly 

 (if at all) widened at the middle, rather stout ; lobes oblong, subobtuse, 

 3 to almost 4 lin. long, \\ lin. broad, slightly silky at the base. Stamens 

 inserted at the middle of the corolla.-tube ; anthers ovate-oblong, sub- 

 obtuse, slightly over h lin. long. Ovary ovoid, quite glabrous ; style 

 and stigma somewhat over 1 lin. long. Fruit globose, up to 2 in. in 

 diameter, dark brown (when dry) mottled with yellow and dotted with 

 minute raised warts ; seeds up to 7 J lin. long, 2i-3J lin. broad ; testa 

 reddish-brown, irregularly pitted. — Clitandra kilimandjarica, Warb. in 

 Tropenpfl. iv. (1900) 614, and in Rev. Cult. Colon, viii. (1901) 45.

This yields according to Warburg very good rubber.
