appearance. It usually runs up straight to 90 ft. or so before commencing 
to branch, and never attains quite the same girth, the largest specimen I have 
seen measuring barely 8 ft. in diameter. Diameters of 4-6 ft. are not 
uncommon. Bark light grey, smooth but often much laminated, and lacking 
the bitter taste of A haya nyasica. Red where cut. Heartwood a deep grey- 
brown in colour, sapwood dull whitish. The timber is handsome, but fre- 
quently eross-grained and difficult to work. It has been used a great deal 
locally for outdoor work, being very durable and untouched by insects. The 
crown of the {тее is frequently not very large in proportion to its height. 
The foliage where exposed to sunlight is dark green and glossy, and the 
young leaves are pale green. The trees are in full bloom in January. So 
far as I know at present, the tree grows only in Chirinda, where it prefers 
well-drained slopes to banks of streams."

This species differs from the plant figured by Guillemin and Perrottet in 
their Fl. Seneg. t. 34, by the leaves being more generally oblong and more 
abruptly attenuate at the apex, the longer petiolules and shorter style. The 
flowers of Perrottet n. 130 will be found on dissection to differ in certain 
partieulars from the structure of the plant as figured.

“А huge tree attaining a height of 150 ft. or more, and exceptionally a 
diameter of 15 ft. ; one that I measured in the Inyamkuwha forest patch 
having attained this diameter at 8 ft. from the ground just above the buttresses. 
Diameters of 5-8 ft. are not uncommon. The trunk is almost invariably 
very straight, and runs up to a eonsiderable height before branching; the 
young saplings have much the appearance of young Castilloa elastica. 
Bark light grey, thick, smooth or laminated, astringent in taste, reminding 
one of quinine, hence the native name ** Umbaba," meaning to be bitter.
