PLUMBAGINEÆ. 
1. PLUMBAGO ZEYLANICA, L.; DO. Prod. ii. 692; App. Speke's Journ. 645. 
Hab. Inenge, Usagara, 67 80! S. lat., Col. Grant! Widely spread in the Old-World 
ігорісв. 
[This is the only plant I could find іп flower at our салар of Inenge іп December before erossing the 
east-coast range for the interior. There were no leaves on the stem, which is very sticky. Flowers 
diminutive and white. It grows amongst rocks where there is no water, and at an altitude of 4000 feet 
at 63° S. lat.—J. А. 6.) 
OLEINEÆ. 
1. ІЛХОСТЕВА NILOTICA, Oliv., sp. nov. Arbor excelsa, glabra ; ramulis teretibus albes- 
centibus; foliis ovali-oblongis, obtusis v. obtusiusculis; paniculis brevibus axillaribus 
v. ad nodos vetustos defoliatos; petalis lineari-lanceolatis, glabris. 
Folia glabra, 3-5 poll. longa, 1-13 poll. lata, apice sæpe angustata, obtusiuscula, basi cuneata ; petiolus 
canaliculatus, 2-2 poll. longus. Inflorescentia in ramulis annotinis paniculata v. racemosa, 1-2 poll. 
longa, glabra v. eum bracteis parvis lanceolatis pubescens; ramuli laterales, 2—1 poll. longi; pedicelli 
brevissimi. Flores 1-1 poll. longi. Calyx lobis ovatis. Petala per paria mediantibus staminibus 
cohærentes. 
Hab. Madi, Dec. 1862 (Chionanthus ? sp., App. Speke’s Journ. 639), Col. Grant! We 
have probably the same species from Mr. Petherick. 
[A lofty tree, with 6 to 8 feet girth of stem; іп low ground, below the rocks at Madi, December 
17. Leaves like those of our peach-tree, but smooth; the side and mid ribs pressed in from above ; 
the side ribs rather distant, and nearly at right angles to the midrib. Flowers sweetly scented ; corolla 
white, deciduous, twice the length of calyx. Stamens two, very large, inserted in the corolla-throat. 
Fruit the size of large peas, in clusters, of several colours, black with red and white, like the fruit of 
Syzygium guineense, DC.

Hab. By the Nile, lat. 7° N., March 1863 (App. Speke's Journ. 645), Col. Grant ! 
Folia ovata v. ovato-lanceolata, obtusa.  Paniculæ axillares et terminales; ramulis divaricatis, pedicellis 
brevissimis subnullisve. Corolle lobis calycem duplo excedentibus, arcte reflexis, late ovato-oblongis ; tubo 
inappendiculato. Anthere exsertæ. | 
The African plant, which is widely spread through the continent north of the equator, differs from 
the Indian (Peninsular) form (S. Wightiana, РІ.) in having the flowers very nearly sessile. In this 
respect, however, it accords with the original plant of Dr. Garcin’s from the Persian Gulf, upon which 
Linnæus based the species. 
- [A large bush with white bark ; plentiful on the banks of the Nile in March, about 199 N. lat. and also 
further up the river. Now (March) in fruit, which is а small green berry. Our men knew the tree, and 
make tooth-scrubbers of its branches. The Turks called it “ arak.”—J. A. G.] |
