3-lobed, lobes in the same plane, acute, furnished towards the base 

 and between tlie lobes with numerous resinous glands, otherwise 

 smooth, about 1 lin. long.

Widely distributed throughout the North Temperate Zone. 



This is the first and only record of Myrica (Jalr, Linn., the common European 

 " Bog-myrtle," from the Southern Hemisphere, and in including it in the 

 present work we rely entirel}' on the correctness of Buchanans lab<l, for thi-re 

 is no doubt as to the identification of the spt-cimen to which it is attached. 

 Buchanan collected the plant on July ()th, 1S70, and his label indicates that it 

 was gathered in the Shire Highlands " near the top of the mountain " (probably 

 Mt. JMlanji). If it really be native there, and it is very improbable that in 

 1870 it could have been introduced, it affords an additional and jmrticularly 

 striking example of the close affinity or identity of several of the plant* (if the 

 high mountains of tropical Africa with species confined to the North Temperate 

 Zone. On this subject consult Engler in Annals of Botany, xviii. r)23-540. 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 2J 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, 2-3J in. long, \-\\ 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 

 at the base of the young shoots, or axillary, and then about twice 

 the length of the petiole, sometimes with one or two flowers at the 

 base ; 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, f lin. long. Fruits ellipsoid, 2 lin. 

 long, closely warted. — M. salicifolia, A. Cheval. Monogr. Myric.
