CLASS V. ORDER II.] TORILUS. 401 



margin. Umbels lateral and terminal, the general of three or four 

 long, stout, rough, furrowed rays, the partial of numerous short unequal 

 ones, the central ones mostly with abortive flowers. Flowers rose 

 colour, the central ones nearly regular, the outer ones radiant, with one 

 or two petals, larger than the rest, and bifid. Petals inversely heart- 

 shaped, with a small' inflexed bind point. Stamens with short fila- 

 ments and small ovate anthers. Styles short, stout, with small obtuse 

 stigmas. Calyx broadly lanceolate acute segments. Fruit oblong, 

 laterally contracted, almost divided. Carpels with two ridges placed 

 upon the margin of the commissure, the remaining seven with two or 

 three rows of equal prickles. Channels obliterated, vittee beneath the 

 secondary ridges simple, rough. Albumen convex at the back, deeply 

 channeled in front. 



Habitat. Fields in a chalky soil, rare; frequent in Cambridgeshire. 



Annual ; flowering in July. 



This, the most beautiful of the tribe, is made a separate genus by 

 Hoffmann, on account of its laterally contracted nearly double fruit, 

 two of the ridges being placed on the margin of the commissure, and 

 the others having two or three rows of prickles ; in other respects it is 

 not different, either in character or habit, and these we do not think of 

 sufficient constancy to constitute it a distinct genus. 



GENUS LXXIX. TORI'LUS. ADAUSON. Hedge Parsley. 



GEN. CHAR. Calyx of five teeth. Petals obcordate, with an inflexed 

 point, the outer ones radiant, and deeply bifid. Fruit with the 

 sides compressed. Carpels with five primary ridges, bristly, three 

 at the back, the two lateral ones on the plane of the commissure, 

 the secondary ridges obliterated by the numerous prickles which 

 occupy the whole of the channels, under which are the single 

 vittce. Albumen deeply channeled in front. General and partial 

 involucre of numerous segments Name of doubtful derivation. 

 1. T. Anthris'cus, Gcertn. (Fig. 461.) upright Hedge Parsley. Stem 

 erect, branched; leaves bi-pinnate ; leaflets lanceolate, cut and ser- 

 rated ; umbels terminal ; involucre of several awl-shaped segments ; 

 fruit with simple hooked incurved-prickles.

Root small, tapering, branched. Stem erect, from one to three feet 

 high, much branched from the base, roundish, furrowed or striated, 

 rough, with reflexed rigid hairs, leafy, hard and wiry. Leaves alter-

 scarcely sheathing base, rough and channeled above, leaflets lanceo-
