200 THE UMBELLATE FAMILY. [ Cheerophyllum. 
3. C. Anthriscus, Lam. (fig. 444). Burr Chervil.— An erect, branched, — 
hairy annual, attaining near 2 feet in height, with nearly as. much the 
habit of a Caucalis as of a Cherophyllum. Leaves not large, twice, — 
or the lower ones thrice pinnate, with ovate or ovate-lanceolate segments, 
pinnately lobed and toothed. Umbels small, on short peduncles, opposite — 
to the leaves, of 3 to 7 rays, without general involucres, and but few bracts 
to the partial ones. Fruits ovoid-oblong, not 2 lines long, covered with — 
short, hooked bristles, and narrowed at the top into a very short smooth 
beak. <Anthriscus vulgaris, Pers. 
A weed of cultivation, probably of south European origin, but readily 
spreading with our crops, and now established in scattered localities over 
Europe and Russian Asia. Rather frequent in England and Scotland, 
more scarce in Ireland. £1. spring and early summer, 
XXXT. CAUCALIS. CAUCALIS. 
Hairy annuals, with dissected leaves. Umbels usually compound, with 
partial involucres of ‘several simple bracts, or rarely wanting. Outer petals 
usually larger, and deeply bifid. Fruit ovoid, covered with prickles or 
bristles. Carpels with 3 or 7 dorsal ribs, and 2 on the inner face; vittas 
single under each furrow. Albumen more or less furrowed on the inner 
face. | 
A small European, Asiatic, and African genus, one of the few natural 
ones in the family, if retained entire. It is well distinguished from Daucus 
by the involucre, the shape of the fruit, and the albumen; from the bristle- 
fruited Cherophyllum by the want of the smooth tip to the fruit; from all 
other British compound Umbellifere by the bristled fruits. 
Umbels opposite to the leaves, sessile, or on peduncles shorter 
than the rays. : 
Umbels contracted into little sessile heads. Fruitshort . . 1. C. nodosa. 
Umbels of 3 or 4 slender rays. Fruit oblong, with a short beak Cherophyllum.

1. ©. nodosa, Sm. (fig. 445). Knotted Caucalis—Stems procumbent 
or spreading, scarcely a foot long. Leaves twice pinnate, with small, 
narrow, pointed segments. Umbels forming little heads, closely sessile, and 
opposite to the leaves; they are sometimes composed of 2 or 3 exceed- 
ingly short, scarcely distinct rays, sometimes of a simple cluster. Fruits 
smaller than in the other species; the outer ones covered with short, 
straight or hooked bristles, which on the inner ones are reduced to mere 
tubercles. TZorilis nodosa, Linn. 
On roadsides, and in waste places, in the limestone districts of central 
and southern Europe, and eastward to the Caucasus, extending northward 
chiefly as a weed of cultivation. Common in sunny places in southern 
England and Ireland, more rare in the north and in southern Scotland, 
fl. spring and summer.
