7. CONIUM. Fruit short, broadly ovate, rather strong-scented, compressed at the 



sides, each carpel with 5 strong and more or less wavy ribs: oil-tubes many 

 and minute. Leaves pinnately decompound. 



+*-**- Seed slightly if at all hollowed out on the inner face. 



8. CICIITA. Fruit globular and contracted on the sides, each carpel with 5 broad 



and thickened blunt ribs, and an oil-tube in each interval: the slender axis 

 between the carpels splitting in two. Flowers white. Leaves pinnately 

 decompound, not aromatic. Fruit aromatic. 



8. S1UM. Fruit globular or short-oblong and contracted on the sides, each carpel 

 with 5 strong or corky ribs, and commonlv 2 or more oil-tubes in the narrow 

 intervals. No 4xis or hardly any left when the carpels separate. Flowers 

 white. Leaves pinnate. Not aro'matic. 



10. APIUM. Fruit ovate or broader than long, flattened on the sides, each carpel 



5-ribbed and a single oil-tube in the intervals: axis left when the carpels sep- 

 arate not splitting in two. Flowers white. 



11. CARUM. Fruit ovate or oblong, flattish on the sides; each carpel with 5

12. FCENICULUM. Fruit oblong; the two carpels with a broad flat face, 5 stout 



ribs, and a single oil-tube in the intervals between the ribs. Flowers yellow. 

 Leaves decompound : the leaflets slender thread-shaped. Whole plant sweet- 

 aromatic. 



*- - Fruit winged or wing-margined at lite junction of the two carpels, which are flat 

 on the face and flat or Jlattish and 3-ribbed ori tiie back. Leaves pinnately or 

 ternately compound. 



M- Wing double at tfie margins of the fruit. 



13. LEVISTICUM. Fruit ovate-oblong, with a pair of thickish marginal wings, 



and single oil-tube in each interval. Involucre and involucels conspicuous, 

 the bracts of the latter united by their margins. Flowers white. Plant 

 sweet-aromatic. 



14. ARCHANGELICA. Fruit ovate or short-oblong, with thin or thickish margi-

**++ Wing surrounding the margin of the fruit single, splitting in two only when the 

 ripe carpels separate. 



15. HERACLEUM. Fruit, including the thin and broad wing, orbicular, very flat, 



and the three ribs on the back very slender: the single oil-tubes in the "inter- 

 vals reaching from the summit only half-way down. Flowers white, the 

 marginal ones larger and irregular. Leaves ternately compound. Plant 

 strone-ccented.
