Mozamb. Dist. German East Africa: Usambara; Mlalo, river woods, 
4500 ft., Holst, 2458! Lutindi, Hunda forest, 5000 ft., Holst, 3443! Usaramo; 
Dar es Salaam, seedling plant, Kirk! and cultivated specimen grown at Kew from 
seeds sent by Kirk from Dar es Salaam! 
The description of the inflorescences and flowers has been drawn up from speci- 
mens grown in the Tjikémé Gardens in Java (Schiffner, Trop. Kultur-u. Heilpfi. 
No. 50!) These plants were brought to Java from Ceylon, where seeds had been 
received from Kew. The Usambara 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 exalbuminous is certainly erroneous, JL. watsoniana is very 
closely allied to LZ. crassipes, Radlk., of Madagascar and to L. Buchananii, Stapf, which 
has large fruits and rather 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. L. 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} 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 14-2 lin. long. Flowers in terminal short 
racemes, or small panicles; peduncles very short or up to 1 in. long, 
slender; bracts ovate, subacute, membranous, } lin. long; pedicels up 
to 3 lin. long, horizontally spreading. Calyx scarcely 14 lin. long, quite 
glabrous; sepals broad, ovate, obtuse or subacute, more or less mem- 
branous. Corolla up to 6 lin. long in bud; tube 24 lin. long, slightly 
(if at all) widened at the middle, rather stout; lobes oblong, subobtuse, 
3 to almost 4 lin. long, 1} lin. broad, slightly silky at the base. Stamens 
inserted at the middle of the corolla-tube ; anthers ovate-oblong, sub- 
obtuse, slightly over } 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} lin. long, 2}-34 lin. broad ; testa 
reddish-brown, irregularly pitted.—Clitandra kilimandjarica, Warb. in 
Tropenpfl. iv. (1900) 614, and in Rév. Cult. Colon. viii. (1901) 45. 
Mozamb. Dist. German East Africa: Kilimanjaro; Moshi, received from 
the Foreign Office! and without precise locality, Merker ! 
This yields according to Warburg very good rubber.
