H ab. Asbestos H ills, N o r th -w e st Tasmania, Gunn.— (FI. Oct.)
A remarkably d istinet-looking plant, but in my opinion a very doubtful species. Jlr. Gunn however considered
it very distinct, and called it T. gracilis, a name that is preoccupied by Steetz for a West Australian congener.
The stems are very long (3 feet), weak, slender, diffuse, glabrous or pubescent. Leaves and flowers as in T. p ro cumbens,
but the stamens are very short, and the flowers usuaUy white. Mr. Gunn remarks that it was gathered
on grassy lands and serpentine rocks, and that T. p ilosa, which grew along with it, retained a totally dilferent habit
and appearance ; so that if a variety, its character cannot be wholly attributed to soil or situation.— Plate VII. B.

Ab ou t fifty accurately known species o f th is N atural Order, b e lo n g in g to eleven genera, are found in
Australia, which is perhaps the head-quarters o f th e Order. A ll are endemic, and m ost have a very narrow
range. O f th e se, th e genus P itto sp o rum is th e largest, and its species frequent the east coast, and are
rarer to th e west and south ; whereas all th e other genera, e specially M a ria n th u s aud Cheiranthera, are
more abundant on th e west and south coasts. A few species are found with in th e Tropics and in Tasmania.
B u r sa r ia spinosa appears to b e common to aU th e extratropical coasts, in c lu d in g Tasmania. Endlicher
(P lant. H ü g e l, p. 9) says that th e g en u s SoUya {B illa r d ie r a fu s ifo rm is , Lab., o f.S o u th and W e s t Australia)
is also found in Tasmania j bu t I know o f n o species from tb a t country. P u tter lich also (Plant. P reiss.
p. 2 0 3 ) says th a t h e has examined an authentic specimen o f Labillardiere’s, gathered in T asmania in January
1 7 9 3 . B o th statements probably arise from some errors that are known to have crept into Labillardière’s
localities.
T he affinities o f P ittosporeæ are generaUy considered to be w ith P o lyg a leæ , to which some o f th e genera
are evidently aUied b y many characters. Their exac t p o sition is however disputed, and th ey have by va-
rions authors been compared with Celastrinea, Ru ta ceæ , and Fiti/e ræ . Lin d ley considers that th e curious
g en u s Cheiranthera allies them to D illen ia c eæ ; b u t to m e it rather su g g e sts an affinity with j

The graceful plants belonging to this genus are all extratropical and chiefly Eastern; about seven species are
known.— Climbing, slender shrubs, with alternate, narrow, entire, exstipulate leaves and axUlary pendulous yellow
or purplish flowers. Sepals deciduous, generaUy small. Petals long and narrow, together forming a cylindrical
tube. Stamens five, with slender filaments. Ovary two-celled; omles nmnerous, attached to the axis o f the dissepiment
in two rows. B e rry cylindrical or quadrate, with blunt angles, or somewhat cordate, glabrous or vUlous.
Seeds imbedded in pulp. (Named in honour o f Labillardiere, tbe naturalist to D ’Entrecasteaux’s voyage, and a

Climbing, 3 -6 feet high, glabrous, extremely variable.— Leaves ^ 1 ^ inch long, linear-oblong, obovate, elliptical,
and all intermediate forms. Flowers %-l inch long, yellow-orange, more or less greenish or straw-coloured,
sometimes bluish iu diied specimens. Sepals extremely variable in form. Berries inch long, and proportionately
broad, broadly-oblong or square, with rounded ends, or lobed at the base, generally of a fine blue colom-, but
sometimes greenish or yellowish, quite glahrous. Seeds very nmnerous, variable in size, compressed, hartng an
opaque red-brown testa.— Labillardière’s figure is vei-y typical of a small-leaved state of this plant, wbich abounds in
alpine parts of the Colony and probably also on the southern coast, whence his specimens were obtained ; in more
favom-ed climates it has larger leaves, and Mr. Gunn’s cultivated specimens are very luxuriant.

Readily distinguished from B. longiflora by the much larger foliage, which, as well as the young branches, is
often covered with süky hairs ; by the shorter, more eampauulate flowers, with acuminate petals and larger sepals ;
and cspeciaUy by the cylindrical fruit.— Fi-uit huear-oblong, cyliudrical, glabrous, neai-ly blunt at both ends, green
when ripe, rather acid. Seeds as in B . longiflora.— This differs from the plate in the ‘ Botanical Magazine ’ in the
flower being yellow and not purplish : it more resembles that of B . scandens (tab. 801), but in that the fruit is hairy.
