CALLITRIS ARENOSA.
The oil from the leaves of this tree resembled ordinary pine-needle
oil in odour, but had a marked suggestion of lemon. The principal con-
stituent was limonene, dextro-limonene preponderating. Two specimens

CALLITRIS INTRATROPICA.
The leaf oil is practically a terpene oil, the principal constituents
being pinene, dipentene, and laevo-limonene. Bornyl and geranyl esters
are present in very small amount. Two samples gave the following
values:—
