Brief Analysis showing Relations to Cognate Species. 
Leaves thickly coriaceous , smooth, shining above, the primary veins very prominent underneath, the 
reticulations inconspicuous. 
Fruit globular. C. obovata. 
Leaves more or less coriaceous, the reticulations fine, conspicuous or obsolete on both sides. 
Fruit globular. C. glaucescens. 
Leaves thinly coriaceous, the reticulations fine on both sides. 
Fruit ovoid-elliptical. C. microneura. 
C. glaucescens and C. microneura are found intermingled in the brushes along the whole northern 
coast districts of this Colony as well as Illawarra, and their distinct character (without any intermediate 
forms that we can trace) is maintained throughout. 
This species differs from C. glaucescens in colour, texture and shape of its leaves, in its absence of 
glaucousness, and particularly in the shape of its fruits. The reticulations are also more prominent than 
in the former species, and the specific name is very appropriate. The staminodia are also more acuminate. 
The fruiting perianth is entirely distinct; in C. glaucescens it is “ depressed-globular,” a shape uniformly 
maintained throughout the whole range of the typical species, but in this species it is ovoid-elliptical and 
consistently so. It measures about 6-8 lines long and 3-4 broad, is black and shining, and faintly ribbed, 
The fruits of C. microneura have not hitherto been described. In fine, we have repeatedly examined the 
two species in the brushes from Illawarra to Port Macquarie, and have requested Mr. Baeuerlen, the 
botanical collector of the Museum, to make similar observations on the Richmond River. Our observations 
agree in that we are convinced that the trees are distinct. 
Botanical Name. —Cryptocarya (see Part III, p. 73); microneura , from 
two Greek words, mikros, small or fine, and neuron , a nerve or vein, in allusion to 
the fine reticulation of the veins of the leaf. 
Vernacular Name. — I know of none exclusively applied to this tree. The 
late Sir William Macarthur says that this tree was called “Yellow Wood” in the 
Illawarra, and Teak in the Brisbane Water district, but both these names should be 
reserved for other trees, as has been shown in previous Parts of this work. 
Mr. R. H. Cambage says that it is called “Brown Jack” at West Dapto, 
because of the colour of its bark. 
Aboriginal Name. —“Murrogun” is the name formerly applied by the 
aborigines of the Brisbane Water district, according to the late Sir William 
Macarthur. I have accordingly ventured to suggest this for adoption. 
Synonym. — Cryptocarya glaucescens , B.Br., var. reticulata, Meissn., op. cit., 
p. 73. 
Timber. —The late Sir William Macarthur described this timber in the 
following words in collecting New South Wales timbers for the London Exhibition 
of 1862. 
A noble tree, with lofty cylindrical stem, and ample head. Wood hard, close, and fine in grain, 
cluramejp dark coloured, and frequently very handsome, with a powerful aromatic fragrance throughout. 
Common at Brisbane Water, and said to be a very valuable timber.
