262 LT.-COL. D. PRAIN ON THE MANSONTE.T. 
Note on the Wood of Mansonia Gagei. 
“ The wood-specimens before me consist of :— 
* A. A block from an old dry log of very hard wood, heart- 
wood only, eut in the Kalamet Forest in March 1901 by Mr. 
Hearsey. 
«B. A round from a green tree giving bark and sapwood as 
well as heartwood, the round measuring 103 inches in diameter. 
The bark is 4 in. thick and the sapwood 1j inches. Tree from 
Theingón Choung, eut in December 1901 by Mr. Hauxwell. 
«C. A book-form block, apparently from the same tree as B, 
but bearing a different date, June 1903. 
« D. A small slab, 6 in. x 5L in. x 2 in., eut from the heart- 
wood of a green tree about 4 ft, in girth in Wot-kyi-tal, Kalamet 
Forest, in March 1903. 
« E, Two small pieces of side-slab, bought in the Rangoon 
Market. 
* They all appear to agree in structure, and that may thus be 
deseribed :— 
“ Bark } in. thick, dark greyish brown, with shallow vertical 
fissures, the outer part peeling off in thin irregular flakes. 
Wood very hard, heartwood dark olive-brown, sapwood light 
brown; texture close and homogeneous. Annual rings doubtful, 
but rings are clearly seen though they are difficult to trace: if 
true annual rings, however, there are about 14 to the inch of 
radius, a very slow growth. Pores small, very numerous, arranged 
in more or less conspicuous, but often slightly oblique concen- 
tric lines, evenly distributed : the pores touching the adjoining 
medullary rays on either side. Medullary rays fine, very nume- 
rous, regular, long, about 300 to the inch: a radial section 
showing a finely-marked silver-grain. Weight about 70 lbs. per 
cubic foot.” 
Mr. Gamble informs the writer that the wood-specimens will 
be presented to the Museum at the Royal Botanic Gardens, Kew. 
The drawing (Pl. 10) which accompanies this paper has, with the 
exception of the floral diagram, been prepared by Miss M. Smith. 
It will be noted that the imbrication of the petals shown in the 
diagram reverses the arrangement shown in the fully-opened 
flower (fig. 3). Both representations are correct, as both 
arrangements are at times to be met with in the flowers of the 
same cyme. That given in the diagram appears, however, to be 
the more usual one.
