8. Оснха, sp.? A leafy branch without flowers or fruit, from Madi. Speke's Ap- 
pendix, 628. 
[An ordinary-sized tree. Madi woods, Dec. 1862.—J. А. G.] 
BURSERACEZ. 
1. BoswELLIA, sp.? А single pinnate leaf 15-18 in. long, with about 18 alternate 
oblong-lanceolate, rather obtuse, sinuous, coriaceous leaflets 4—6 in. long. 
Hab. Madi, Col. Grant ! 
[Native name “looban,” or Frankincense. Tree. Madi, 3rd January, 1863, not in flower or fruit. 
Leaf, gum, and bark preserved. .A number of these young trees grew in an open space, as if this locality 
‚ had been that of the parent tree. Each tree was about 5 feet high, and its trunk 15 inches in circumference 
at base; therefore the tree tapered rapidly to its extremity. They bent easily, but were tough to break. 
The bark was rent into black, hard, irregular pieces ; and an incision of the inner bark showed it to be of 
а red carmine colour and without smell. Its gum is a rich, clear amber, tastes sweet, and dissolves in 
the mouth. It is glassy-like, and comes from wounds made by insects in the trunk. Leaves grow alter- 
nately upon the tree; their surface shines; and underneath they are of a dull green colour; edges wave 
very much, and are irregularly toothed ; the leaf is hard and dry to the feel, and has a pleasant smell when 
rubbed. Unknown to most of our men.—J. А. G.]

[This shrubby tree (native names “© m'gazoo" and “ katatee ”) has the appearance of our Blackthorn, 
but 18 more stunted-looking. Bark smooth, of the colour of our plum-trees, but, near the ground, it is 
rougher and cracked into small shapeless parts. Оп scraping the inner bark a colourless juice appears ; 
and from under the bark a milky-white sticky juice exudes, scentless, and seems soluble. Тһе older 
spines are sunk into the bark and grow horizontally with the leaf-branch. Тһе branches end in a sharp 
point. The leaves are very glossy on their surface. The small fruits, in April, were the colour of a 
greengage, but speckled over. "The tree is used as a fence at 3? N. lat.—J. A. G.]
