18. Aruvusa Linn. Fools’ Parsley. 
1. Ai. Cynapiwm (L.); partial involucre of 3 leaves longer 
than their umbel, 1. all doubly pinnate, leaflets lanceolate decur- 
rent pinnatifid— H. B. 1192.—St. 4—12 in. high. L. dark green, 
lid, stinking. General involucre 0; partial one long, narrow, 
pendulous. Herb poisonous.—Cultivated land. A. VII. VIII. 
19. Fanicutum Hoffm. Fennel. 
1. F. officinale (All.); st. terete below, 1. decomposite, seg- 
ments all capillary elongate in the upper 1. flaccid, umbels of 
many rays concave—Meum Sm., E. B. 1208.—Involucres 0. 
St. 3--4 feet high, usually filled with pith, branching. Umbels 
large. FI. yellow. Whole herb aromatic. Segments of 1. chan- 
neled, usually capillary in the wild plant, but the cultivated plant 
with awlshaped segments is probably the same species, and I 
therefore place the F. Piperitium (ed. 2) under this species.—

20. Lisanotis Crantz. 
1. L. montana (Crantz); 1. doubly pinnate cut, segments
