THE COLONY OE VICTORIA. 
173 
or sliort-lobed leaves, purple petals, but slight inequality of filaments, all being pointed, and in the glabrous 
rostrum of the fruit. 
Erodium cicutarium, which in several varieties occurs now rather frequently throughout extratropical 
Australia, seems to be an introduced plant, and is therefore eliminated from this diagnostic enumeration. It 
can readily be distinguished by the pinnatisected leaves with deeply pinnatifid segments, by pink petals with 
stronger bearded and more distinct unguis, by narrower and more gradually attenuated filaments of less 
inequality in length, by more velvet-hairy carpels and by somewhat crenulated or lobulated cotyledons, 
Erodium moschatum, which has likewise become a common Australian weed, differs from E. cicutarium only 
in a musky scent, usually larger stipules, less deeply divided segments of the leaves, often bidentate fertile 
filaments, characters on which perhaps too much dependence has been placed for specific distinction. All the 
accepted species of this genus have to undergo a new critical revision and limitation, their number being 
evidently vastly overrated. 
GERANIUM. 
L. Gen. 350.—Crane’s-bill. 
Calyx devoid of a nectar tube. Petals 5, equal or almost equal. Stamens 10, towards the base 
monadelplious or almost free, biseriate. Filaments from a dilated base subulate, all fertile , rarely 
the five exterior petaline filaments destitute of anthers. Sepaline filaments provided at the base with 
an anterior gland. Awn-like prolongations of the carpels circinate-seceding from the lengthened 
fruit-axis. Cotyledons orbicular, convolute, on one side replicate. 
Herbs, rarely half-shrubs, very rarely (in species from the Sandwich Islands) shrubby plants, 
inhabiting the more temperate and colder regions of the globe, thus within the tropics to be met with 
in high mountain tracts, much more frequent in the northern than in the southern hemisphere, one 
species only indigenous to Australia. Leaves usually in outline cordate, renate or orbicular, often 
deeply cleft. Peduncles axillary or opposite to the leaves, 1-2-flowered, rarely terminal and paniculate. 
Pedicels at the base bibracteolate. Color of petals generally blue, purplish or pink. Carpellar pro¬ 
longations on the inner side smooth, rarely short-downy or villose.— Endl. Gen. 1167. 
The cotyledons verge either into a renate- or cordate-orbicular form; they are folded back on 
one side only in all the species here subjected to examination (viz., G. Sibiricum, G. sanguineum, 
G. lucidum, G. Pyrenaicum, G. Robertianum, G. pfigeum, G. viscidum, G. dissectum).

Diffuse or procumbent, hairy; leaves mostly long-stalked, in circumscription cordate- or renate-orbicular, 
deeply 5-7-cleft; tlieir partitions cut into three or more linear- or semi-oblong’ or broad-linear or dilated cuneate 
and trifid lobes, rarely some entire; stipules and bracteoles usually small, semilanceolate- or linear-subulate, 
membranous; peduncles axillary, 2- or 1-flowered, rarely undeveloped; fruit-bearing pedicels declinate; 
petals cuneate-obovate, entire or slightly emarginate , pink or pale , scantily downy at the base, as long as or 
longer than the short-cuspidate sepals, minutely unguiculate, without anterior basal ridge; stamens all fertile, 
shorter than the calyx, usually thinly downy towards the base, short-connate; staminal glands glabrous; 
styles puberalous, extending but little beyond the carpellar prolongations; carpels downy , without wrinkles ; 
testa densely reticulate.
