Geranium. | XX. GERANIACE®. 93 
with slender, decumbent, slightly hairy stems ; the leaves deeply divided 
as in G. dissectum, but the segments still narrower, mostly linear; the 
peduncles and pedicels long and slender ; the calyx considerably longer, 
with long, slender points. Petals entire or notched, seldom exceeding 
the calyx. Carpels but slightly 2 or quite glabrous, not wrinkled. 
Seeds dotted as in G. dissectum. 
In dry pastures, on banks and waste places, over Hurope and Russian 
Asia, except the extreme north. Not so common as G. dissectum in 
Britain, and very local in Scotland and Ireland. Fl. spring and summer. 
Il. ERODIUM. ERODIUM. 
Prostrate or decumbent herbs, differing from Geranium in the divi- 
sions or nerves of the leaves being pinnate, not palmate; in the stamens 
always reduced to 5, the 5 alternate ones being rudimentary only; in 
the awns of the carpels bearded witli a few long hairs on the inside, 
and spirally twisted after they are detached from the axis. The flowers 
are also frequently more than 2 together, in an umbel on the summit of 
the peduncle. | 
The geographical range is nearly that of Geranium, in which genus 
it was included by Linnzus. But the greater number of the species 
are maritime plants from the Mediterranean regions, or roadside weeds, 
with flowers so insignificant that but few have ever been cultivated. 
Leaves pinnate, with distinct segments. 
Segments deeply pinnatifid, with toothed lobes. Flowers of 
a reddish purple . 1. EH. cicutarium. 
Segments ovate, coarsely toothed or shortly lobed. Flowers 
of a bluish purple . 2. H. moschatum.

1. KH. cicutarium, LL’ Hér. ae 214), diosa #£.— Usually an annual, 
but often forming a dense tuft, with a thick taproot, and in some situa- 
tions lasting at least a second year, always more or less covered with 
spreading hairs, which are sometimes viscid. Stems sometimes exceed- 
ingly short, sometimes lengthening out to 6 inches or near a foot. 
Leaves mostly radical, pinnate, on long stalks, the segments distinct 
and deeply pinnatifid, with narrow, more or less cut lobes. Peduncles 
erect, bearing an umbel of from 2 or 3 to 10 or 12 small purple or pink 
flowers. Sepals pointed, about the length of the obovate, entire petals. 
Carpels slightly hairy, the beak varying from 16 to 18 lines in length. 
In waste and cultivated lands and dry pastures, especially near the 
sea, and on roadsides; very common in Kurope, northern Asia, and 
North America, short of the Arctic Circle. Generally distributed over 
Britain. Fl. spring and summer. A maritime, more viscid, and hairy 
variety, known in southern Europe as £&. hirtum, is also found on our 
own coasts. 
2. E. moschatum, L’Hér. (fig. 215). Musk 2.—A much larger and 
coarser plant than &. cicutarium, often strongly smelling of musk. 
Stems often a foot long. Leaves on long footstalks, with from 9 to 11 
distinct, ovate segments or leaflets, often cordate at the base, and 
deeply toothed or shortly pinnatifid. Flowers generally numerous 
in the umbel, of a bluish-purple, rather larger than in L. ctcutarium,
