PLANTS INDIGENOUS TO 
[JRutacea, 
recurved at the margin, smooth or frequently beneath thin-velvety, strongly veined; cymes axillary, gene¬ 
rally trichotomous-paniculate and velutinous; bracts and bracteoles lanceolate or lanceolate-subulate, sepals 
twice to four times shorter than the whitish subvelutinous corolla, semilanceolate or subdeltoid; petaline 
stamens wanting ; sepaline filaments as long 1 as the calyx or somewhat longer, almost smooth; anthers 
without appendage ; style short; stigma depressed, slightly four-lobed; disk deeply four-cleft ; carpels 
quadrate-ovate; endocarp protracted at the junction of the valves into a deltoid tooth ; seeds shining*, finely 
wrinkled. 
From the Grampians and the Cape Otway Ranges eastward, scattered along the humid forest-valleys of 
Victoria, thus occurring on Mount Disappointment, in the Dandenong Ranges, at Wilson’s Promontory, and 
in various parts of Gipps Land, ascending to high mountain ravines; not rare in Tasmania; dispersed over 
Eastern Australia as far north as Moreton Bay. 
A shrubby plant, becoming under favorable circumstances arborescent, when it is found to attain a 
height of 30 feet, exhaling a strong not agreeable odor. Bark grey. Wood pale-yellowish, close-grained. 
Branchlets often thinly grey-velvety, sometimes from the beginning glabrous, occasionally glandular- 
tuberculate. Petioles semiterete, narrow-margined, sometimes channelled, often obscurely velvety, generally 
between f and 1J inch long, extending occasionally to the length of 2 inches, whilst in small-leaved varieties 
it becomes much shortened. Leaflets generally from 1J-3 inches long, attaining, however, the length of 6 
inches in luxurious specimens, shortened to a length of less than J inch in stunted specimens grown in 
exposed highland situations, dotted with more or less pellucid oil-glands, occasionally" also somewhat tuber- 
culated, glabrous and somewhat shining rarely thin-velvety above, frequently covered with an exceedingly 
thin grey velvet beneath, although occasionally on both sides quite glabrous, keeled with a somewhat promi¬ 
nent midrib, producing very divergent towards the margin anastamosing veins. Primary peduncles in most 
cases not much longer than the petioles, cylindrical, bearing a decompound cyme generally from 1 to a few 
inches long with numerous flowers, occasionally", however, in meagre specimens furnishing a simple few- 
flowered cyme. Pedicels more frequently- shorter than longer than the flowers. Bracts lanceolate or linear- 
lanceolate or canaliculate-linear, acute, 1-4 lines long, in one variety early dropping, in another rather long 
persistent. Bracteoles J— 2 lines long*. Sepals line long*. Petals broad lanceolate-subovate, very short - 
unguiculate, terminated with a minute point, one-nerved, valvate in prmflorescence. Filaments white or 
pale-pink, filiform, minutely glandulous at the apex, rarely scantily puberulous. Anthers pale, cordate- 
roundish, in large-flowered varieties nearly J line long, in small-flowered varieties only | fine or even less 
long. Pollen-grains orange-colored, ovate, smooth. Style green, filiform, line long. Stigma broader 
than the style, smooth, greenish. Disk divided to the base into four half-round smooth purplish or pink 
fleshy turgid lobes, from which at the back the filaments arise. Carpels 1J-2 lines long, truncate, hardly 
apiculate, one or the other frequently tabescent. Endocarp pale-yellowish, somewhat shining, nerveless. 
Seeds brown-black, oblique ovate, |-1 line long, one in each cell; if rarely two occur, then angular from 
mutual pressure. Placental membrane tender, whitish, triangular, closing the opening, which whilst the 
valves cohere is formed near the base of the internal angle of the endocarp. Albumen copious. Embryo 
very slender, cylindrical, nearly as long as the albumen. 
The forms which, under varied circumstances, this plant is capable of assuming* are singularly- discre¬ 
pant, but become confluent by numerous mediating stages of the species. A small-leaved everywhere downy 
variety, to be found near Port Jackson, accords with the definition of Z. cytisoides. A few-flowered variety 
is known from various parts of Eastern Australia, in which state the calyx is very small and the petals are 
reduced to the length of 1 line, whilst the narrow bracts remain long* persistent. Another singular variety, 
with dense velvety- indument in all parts, even in the fruit, with a more agreeable strong aromatic scent and 
densely tuberculate branches, was brought from the forest-gullies of the Hastings River by Dr. Beckler. 
Even B. granulata seems to be only an extreme state of this plant with linear leaves, which are prominently 
dotted, whilst the branchlets bear copiously a glandular granulate secretion. Another variety collected on
