midrib, minutely inflexed-pointed at tlie apex. Filaments glabrous, inserted to the faint bends of the annular 
glabrous disk, generally twice or thrice shorter than the petals, occasionally only one-tliird shorter. Anthers 
didymous- or cordate-roundish, pale, dorsifixed, line long*, two-celled, with introrse dehiscence. Pollen- 
grains ellipsoid, smooth, with longitudinal fissure. Style very short, five-furrowed, glabrous. Stigma de¬ 
pressed, roundish, indistinctly five-angular. Ovaries in exceptional cases with two collateral ovules. Carpels 
often only in part developed, ovate-globose, turgid, seldom longer than 2 lines, bivalved. Sarcocarp dotted 
with oil-glands. Endocarp parchmentous, livid, nerveless, remaining with the exception of the margin 
attached to the sarocarp. Seeds ovate-globose, quite smooth, carrying with them the nearly linear placentar 
membrane, filling almost completely the cavity of the carpel. Exterior part of the testa thin and brittle, 
interior one hard and thick. Albumen present according to Schott. Embryonic structure remaining unknown, 
none of the many seeds, examined on this occasion, having the nucleus developed. 
In flower during the spring. 
This species resembles in every respect, as regards flowers and fruit, G. salicifolia, which merely by the 
generally ovate or broad-lanceolate long-stalked veined and beneath paler leaves and often larger and copiously 
ilowered panicle can be distinguished from G. parviflora. As G. latifolia, which is intermixed with G. parvi- 
ilora in the Brigalow scrubs of East Australia, mediates the transit from our plant to G. salicifolia, it becomes 
very doubtful whether all are not merely forms of one species, holding the same relation to each other as 
Dodomea Preissii to D. viscosa,* for it can well be imagined what effect the dry desert climate would exercise 
on a plant, capable to bear it, whilst it adapts itself also to our humid jungle-clime. 
G. salicifolia occurs southward at least as far as Cabranatta, according to Mr. W. Woolls, and northward 
as far as Rockhampton, according to Mr. Anthelme Thozet. The 'wood *vvas exhibited by Mr. C. Moore under 
Is. 78 in the Paris Exhibition. Mr. Thozet prepared an excellent ink from the bark. A doubtful species, 
with almost rhomboid short-rostrate carpels, has been noticed near Moreton Bay; no others are known.

Sepals 4, valvate in aestivation, persistent, rarely deciduous. Petals 4, sessile or subsessile, val- 
vate or imbricate in prac florescence, persistent or tardily dropping. Stamens 4, opposite the sepals or 
8 ; those opposite the sepals longer than the rest and sometimes bearing barren anthers, very rarely 
those opposite petals sterile. Filaments free, linear-subulate or filiform or subclavate, generally 
inflexed at the apex. Fertile anthers dorsifixed, with introrse longitudinal dehiscence. Ovaries 4, 
inserted on a sinuate or undivided disk. Ovules 2, affixed at the interior angle of the ovary; the 
upper one ascendent, the lower one descendent. Styles united into one or wanting. Stigma simple 
or four-lobed. Carpels normally 4, oblique-oblong or ovate, bivalved, 1-2-seeded. Endocarp cartila¬ 
ginous, bivalved, operculate towards the base by the placental membrane. Seeds subovate. Testa 
crustaceous. Embryo cylindrical , straight, in the axis of the copious albumen. Radicle longer than 
the plane-convex cotyledons or nearly as long. 
Odorous shrubby rarely suffmticose or arborescent plants, inhabitants of extratropical and sub¬ 
tropical Australia and of Tasmania, rare within the tropics and towards the centre of the Australian 
continent. Leaves opposite , simple or impari-pinnate or with ternate or bitemate leaflets even 
sometimes in the same species, very rarely some alternate or fasciculate or verticillate. Flowers 
solitary, geminate, ternate, cymose or paniculate. Pedicels at or above the base jointed, and almost 
aw r ays at the joint provided with two opposite bracteoles, often incrassate at the apex. Petals gene¬ 
rally longer than the calyx and the stamens, pink, sometimes crimson, blue or whitish, very seldom
