Widely distributed throughout the North Temperate Zone. 
This is the first and only record of Myrica Gale, Linn., the common European 
*‘ Bog-myrtle,” from the Southern Hemisphere, and in including it in the 
present work we rely entirely on the correctness of Buchanan’s label, for there 
is no doubt as to the identification of the specimen to which it is attached. 
Buchanan collected the plant on July 6th, 1879, and his label indicates that it 
was gathered in the Shire Highlands “near the top of the mountain ” (probably 
Mt. Mlanji). If it really be native there, and it is very improbable that in 
1879 it could have been introduced, it affords an additional and particularly 
striking example of the close affinity or identity of several of the plants of the 
high mountains of tropical Africa with species confined to the North Temperate 
Zone. On this subject consult Engler in Annals of Botany, xviii. 523-540. For 
complete references and synonymy see Sargent, Silva of North America, ix. 84, 
2. M. arborea, Hutchinson in Kew Bulletin, 1917, ined. A tree 
20-30 ft. high ; branches fairly stout, about 23 lin. thick, sulcate, 
closely puberulous and glandular; young branchlets fairly densely 
leafy, almost tomentulose. Leaves oblong or oblong-lanceolate, 
rounded to a shortly mucronate apex, mostly truncate and unequal- 
sided at the base, 2-34 in. long, 3-1} in. broad, rigidly chartaceous 
or subcoriaceous, mostly dentate or subserrate all round the margin, 
rarely subentire, glandular on both surfaces, more densely so below, 
otherwise glabrous ; midrib prominent below; lateral nerves 12-16 
on each side of the midrib, diverging from it almost at right angles, 
mostly distinctly 2-furcate towards the margin, slender, prominent ” 
on both surfaces ; ultimate venation scarcely visible ; petiole 2-3 lin. 
long, glandular and shortly pubescent. Flowers monoecious. Male 
Spikes axillary, mostly about twice as long as the petiole or some- 
times racemosely arranged on long leafless shoots ; rhachis velvety- 
tomentulose ; bracts very broadly obovate, nearly 1 lin. long, sub- 
membranous, ciliate, glandular and pubescent outside; stamens 
about 6; anthers very sparingly pubescent. Female spikes borne 
ut the base of the young shoots, or axillary, and then about twice 
he length of the petiole, sometimes with one or two flowers at the 
nase ; bracts broadly triangular, about 1 lin. long, submembranous, 
glandular and slightly pubescent outside, ciliate; hypogynous 
scales pubescent and glandular; ovary pubescent and glandular ; 
styles flattened, broad, acute, 3 lin. long. Fruits ellipsoid, 2 lin.
