“Timber yellow with occasional black strands, inferior; similar 
to D. sylvatica; wood parenchyma wide lumined, tracheal elements 
rather low percentage number; large radical strands of parenchyma 
occur in the wood (cf. D. quesita); the coloured contents are not 
abundant; timber used for buildings. The wide lumined parenchyma 
and the sparse contents of the secondary xylem elements prove the 
timber to be of inferior quality.”’ (Wright 1. c. p. 160.)

‘“ The timber is very variable. The young trees have usually a smail 
black or brown heartwood, and a sapwood of a faint red tint; large 
trees possess a coloured heartwood of considerable size; one tree 
having a total diameter of 690 mm. had a heartwood of 440 mm. 
diameter. The heartwood of such trees is invariably irregular in out- 
line and presents a beautiful alternation of black and brown layers, 
which from an ornamental point of view greatly enhances, the value 
of the timber; such specimens are almost equal to calamander for 
ornamental purposes.’’ (Wright I. c. p. 163.)

‘* Timber when freshly felled is yellow or white with a variable but 
usually small quantity of black heartwood; inferior but often used for 
fancy work and buildings.’’ (Wright 1. c. p. 171.)

‘“Male flowers in bud are green, pubescent, 5 mm. long, 
3 mm. diameter; open flower 13 mm. long; there is much 
variation in the number and orientation of the members of 
accessory whorls and stamens. Calyx yellowish-green, 
pubescent, campanulate, 5-8 mm. long, 5 mm. diameter, 
occasionally very small; segments 3-6 and accrescent, 
apex acute, I°5-3 mm. in length. Corolla yellowish- 
white, narrow-throated, outside covered with silky hairs, 
12 mm. long, 3 mm. diameter; segments 4-6 usually 5, 
rotate, rounded or acuminate apex, 2 mm. long, 2 mm. wide. 
Stamens indefinite, 8-10-16-20, never epipetalous but ter- 
minate central disk, arranged singly or in equal or unequal 
groups of 2 or 3; in one case 15, arranged (a) outer whorl 
of 8, four in two connate adjacent pairs, and four successive 
separate stamens; (b) inner whorl of 7, two of which were 
connate (cf. D. pruriens); in another case 13, ten in 5 pairs 
with anthers of inner stamens shorter than outer, two as a 
pair with anthers of equal length, and one separate stamen 
with long anther and filament; anthers yellow, glabrous, 
slightly apiculate, 1-8-3 mm. long, opening by longitudinal 
Part IItf.
