A tail, liandsome species, 2 - 4 feet high, exuding copiously a balsamic giun, that smells o f tui-pentine and
somewhat o f Mangos {Gunn).— Branches and branchlets usually pubescent aud covered with tubercles, each containing
an oil-gland, but sometimes smooth. Leaves pinnate ; petioles stout, 4—4 inch long, often flat and dilated ;
leaflets two or three pair, more or less obovate-lanceolate or obovate-spathulate, membranous or coriaceous, theii-
apices acute, blunt, rounded, retuse, or in broader leaflets bi-trifid, studded ivith large glands, very variable in
length aud breadth, 4—4 inch long, generally ivith an evident prominent midrib. Floivers vei-y numerous, pink,
variable in size, similar to those o f B. p ilosa.— Narrow-leaved states closely resemble B . anethifolia, A. Cunn,,
of New South Wales. The membranous state of tbis, with spathulate, broad, retuse, or lobed leaflets, looks quite
distinct from any ê f its congeners, but Gimn’s suites of specimens show that it passes directly into the following ;
it is the B . dentigera of D r. Müller, and is also found in South-eastern Australia.

As handsome a species as B . Gunnii, but not so tall ; it is very difficult to distinguish it from that plant, except
by the strong and delicious smell of lemons, the fewer, far more coriaceous leaflets, and shorter petioles. Gunn
observes that the seeds are larger and longer in this, but the difference is slight, and can only he detected by comparison.
Gunn’s 894 ? are small specimens o f the same (as he suspects himself).

A b o u t e igh ty Australian species o f LtJiamnex are k n ow n ; w ith very few exceptions all o f th em are
extratropical. Th e great majority be long to the two genera Orgptandrra, and P om a ie r r is , or to their im m ediate
allies. Ab ou t au equal number are found on th e E a s t and W e s t Coasts, and none are common to
both. T he W e s t Coast species are by far th e most peculiar, in so far as th a t all o f them b e lon g to genera
confined to Australia, ex cep t P om a d e rris, whereas the A siatic genera Ventilago, Colubrina, and ZizgpJms,
and the South American genus D isc a ria , are all found on th e N o r th and E a st Coasts. There are only
six or eigh t tropical Australian species, in c lu d in g several A sia tic Z iz y p ld and Colubrina:, and there is also
