— Myrrhis.) XXXKV. UMBELLIFERZ. 197 
A single species, scarcely distinct as a genus from Cherophyllum. 
1. M. odorata, Scop. (fig. 442). Sweet Cicely—An erect, branching, 
hairy perennial, 2 to 3 feet high, with the foliage and habit of a Chero- 
phyllum and highly aromatic. Leaves large, thin, twice or three times 
pinnate, with numerous lanceolate segments, deeply pinnatifid and 
toothed. Umbels terminal, not large, with seldom more than 8 or 10 
rays, and of these but few ripen their fruits. No general involucre ; 
bracts of the partial ones lanceolate, thin whitish, with fine points. 
Fruits when ripe 6 or 7 lines to near an inch long; the very prominent 
ribs occasionally rough with minute hairs. 
A native of mountain pastures, in central and southern Europe, from 
the Pyrenees to the Caucasus. Of ancient cultivation in more northern 
Kurope, it has frequently established itself in the neighbourhood of 
cottages. In Britain, believed by some to be truly indigenous in the 
hilly districts of Wales, northern England, and Scotland, where, at any 
rate, it is perfectly naturalised. FV. spring and carly summer. 
XXIX. CONOPODIUM. CONOPODIUM. 
Leaves dissected. Umbels compound, either without involucres or 
with very few small bracts, and white flowers. Fruit oval-oblong, 
somewhat laterally compressed, shortly contracted at the top, with 
erect, or slightly spreading styles. Carpels with 5 scarcely perceptible 
ribs, and several very slender vittas under the interstices. Albumen of 
the seed, with a longitudinal furrow on the inner face. 
A genus of few species, chiefly from the Mediterranean region, with 
the habit of the tuberous Carums, but with a fruit more nearly allied 
to that of some Cherophyllums, although shorter. 
1. C. denudatum, Koch. (fig. 443). Harthnut, Pignut.—The perennial 
stock consists of a globular tuber, the annual stems erect, slender, 
glabrous, 1 to near 2 feet high, with a few forked branches. Radical 
leaves few and decaying early, with 3 long-stalked segments, each once 
or twice pinnate; the ultimate divisions short, narrow, pointed, entire 
or 3-lobed. Stem-leaves few, with narrow-linear divisions; the central 
lobe of each segment much longer than the lateral ones. Umbels 
terminal, or one opposite the last leaf, of 6 to 10 rays. The ribs and 
vittas of the fruit are scarcely perceptible. Buniwm flexuwosum, With. 
In woods and pastures, chiefly known as a west Huropean plant. 
Much more common in Britain than Carum Bulbocastanum, which is also 
known under the name of Pignut. Fl. summer. 
XXX. CHAAROPHYLLUM. CHERVIL. 
Leaves dissected. Umbels compound, with partial involucres of 
several bracts, and white flowers. Fruit narrow-oblong or linear, con- 
tracted at the top, and sometimes forming a beak always much shorter 
than the seed. Carpels with 5 ribs, sometimes only apparent at the 
top, either without vittas or with one vitta under each interstice. Seed 
marked with a longitudinal furrow on the inner face. 7 
_ A considerable and rather natural genus, widely diffused over the 
northern hemisphere without the tropics. It is usually divided into
