nearly as wide, 3-celled, contracted towards orifice and not recurved, rim narrow 
and plain; valves deeply placed, and when open still wholly below rim. i atuee 
wood deep red in colour, remarkably free from defects,, easi y wor e , s ow o 
burn, and exceedingly durable in either dry or wet situations. 
CULTIVATION IN NEW ZEALAND. 
E. marqinata is in the first rank for quality and durabdity of timber, but in 
the second or third rank for rapidity of growth even in its own country. 1 lanted 
as an exotic in New Zealand, it has rarely yet exceeded the dimensions of a shrub 
or small tree. The best specimens noted by the writer were m the railway reserve 
at Mount Albert, Auckland. These in 25 years had reached heights of about 
30ft. and diameters of 12in. to 15in., while other species planted at the same 
time in the same reserve had reached heights of 80ft. to 100ft., and diameters of 
2ft. to 2ft. 6in. The destruction of the plantation some years ago preyen e 
further observations, except to note that the E. marginata stumps contained a 
crood percentage of red heartwood. Further trials in warm northern localities 
may yield better results. Seed should be obtained through the Western Australia 
Forest Service. 
The specific name marginata was suggested by a vein or thickening along the 
margin of the leaf, a character subsequently observed in some other species, lhe 
vernacular name jarrah belongs almost exclusively to this species. 
A eucalypt somewhat similar to E. marginata, and found in southern parts 
of the same tree region, was some years ago described and named by Maiden as 
E. Jacksoni. It is a species that grows to. large dimensions and yields a red 
coloured heartwood believed to be of very high merit for economic purposes. In 
view of the difficulty we have experienced in trying to acclimatize E. marginata, 
experimental attention might well be turned to E. Jacksoni. The Western Aus¬ 
tralia Forest Service will be able to supply seed from best selected trees.

NATURAL HABITAT, DESCRIPTION, AND USES. 
Natural habitat in south Western Australia, on uplands not very remote 
from the sea, latitude 32 to 34. Trees reported to exceed 100ft. m height with 
corresponding diameter of bole. Dead bark of the woolly sub-fibrous type, per¬ 
sistent on stem and branches. Leaves in juvenile stage sessile, broad; those of 
adult tree 4in. to 8in. long by lin. or more wide. LTmbel with few flowers; stalk 
y 2 in., stalklets %in.; lid of bud a low dome with slight central projection; anthers 
with nearly parallel openings. Ripe seed-cup in largest form up to %in. deep by 
%in. wide, but often smaller, contracted towards orifice and not recurved, rim 
plain and narrow; valves usually 4, wholly below rim. Mature wood pale, too 
interlocked for easy splitting, but valuable when sawn into planks and scantling. 
CULTIVATION IN NEW ZEALAND. 
Reports from native home encourage trial in warm localities of North Island. 
Seed should be obtained through the Western Australia Forest Service.
