PLANTS INDIGENOUS TO 
[Tremandrece. 
A half-shrub with the habit of a Boronia, attaining the height of 3 feet ; usually, however, more dwarf, 
producing in most instances many erect ascending or diffused rather slender stems from the stout woody 
root. Branches less frequently smooth than hairy, some of the hair occasionally terminated with a gland. 
Leaves herbaceous or thin-coriaceous, varying in length from about 2-9 lines, quite entire or somewhat 
repand or seldom imperfectly crenulated, glabrous or in various degrees downy from pale hair, above dark- 
green, beneath paler; the midrib rather strong; the lateral nerves and veins faint. Pedicels thin-filiform, 
usually black-purple, arising solitary or geminate from the axis of leaves, spreading or recurved, at the apex 
considerably thickened, at the base beset with two bracteoles, from nearly equal to double the length of the 
leaves, either quite glabrous, or oftener more or less short- and pale-hairy and simultaneously beset with 
some longer black-purple gland-bearing hair. Bracteoles less than 1 line long, subulate-linear, channelled, 
sometimes ciliolated, deciduous. Sepals usually black-purple, §-I line long, adnate with their truncate base 
to the dilated summit of the pedicel, slightly acuminate, inside especially towards the margin and midnerve 
short-hairy, outside clothed with an indument similar to that of the pedicel. Petals oblong-oval, slightly 
tapering to the base, more variable in size than the sepals, thus from 2A-8 lines long, entire, clothed with 
very thin only under a lens observable pubescence, usually of a rosy purple, rarely white or pale-red’ the 
midnerve tender; the veins very fine. Stamens from 1-1 g line long, sometimes quite blunt, usually 
attenuated into a short and paler apex; the tetragonous-cylindrical anthers confluent with the filament ; 
the pore terminal, minute, occasionally almost lateral and large. Pollen-grains pale, ellipsoid, smooth, with 
longitudinal fissures. Style hardly longer than 1 line, thin-subulate, reddish towards the base, fulvous-pale 
towards the summit, very minutely downy below the middle. Ovary covered with very short grey and 
sometimes also with scattered longer dark gland-bearing hair; the cells rarely containing three ovules. 
Capsule 2-4 lines long, bent downward, outside covered with exceedingly short hair, amongst which some¬ 
times a few longer gland-hairs are scattered, inside smooth. Seeds dark- or grey-brown, 1-1| line long, 
scantily clothed with short patent soft pale hair, when 1 in each cell ovate, when 2 truncate-ovate. 
Appendage of seed either spirally coiled or variously twisted, pale, especially upwards. Albumen amygda¬ 
loid. Embryo yellowish, transparent, thin-cylindrical, straight, shorter than the albumen. Radicle about 
as long as the cotyledons.

Branches terete ; leaves scattered or crowded or verticillate, linear or lanceolate or oblong or ovate or 
rhomboid , often revolute at the margin, seldom wanting; sejyals oppressed, rhomboid- or orbicular-ovate, 
often acuminate, as well as the petals usually 4, stamens usually 8 ; anthers smooth, four-celled, black-purple, 
tapering into a compressed short filament ; their cells longer than the tubular apex ; cells of the ovary 1-2- 
ovulate; capsule cuneate- or orbicular-obovate. 
On heath-traots of the mountains and ridges in many parts of this colony, ascending to alpine eleva¬ 
tions, extending to St. \ incent’s Gulf, Kangaroo Island, Tasmania, Flinders Island and Moreton Bay. 
A suffruticose or shrubby plant, variable in aspect, attaining* the height of several feet, sometimes quite 
dwarf, in alpine localities and much exposed barren spots occasionally depressed. Indument variable, some¬ 
times glandulous, sometimes deficient. Leaves from 2-10 lines long. Pedicels measuring from 1-14 lines. 
Flowers so similar to the various varieties of the preceding species as to render their description here 
needless. Petals in alpine varieties sometimes reduced to lj line length. Fruit-capsule usually narrower 
than that of P. ciliata, otherwise as well as the seeds similar to that species.
