UMBELLlFERiE, 155 CRTPTOTJENIA, 



quinate leaves. Near the top it divides into two or more short branches, each 

 of which divides again into peduncles, with small, capitate umbels of minute, 

 white flowers. At the points of these divisions are situated leaflets apparent- 

 ly ternate, resembling involucres. Leaflets oblong-lanceolate, pointed at each 

 end, cut into irregular, mucronate serratures, the lateral ones often confluent 

 at base. Most of the flowers barren. Tube of the calyx echinate. Petals 

 with a closely inflexed point, apearing emarginate. Jn. Sanicle. 



2. DAUCUS. 



Involucre pinnatifid; the central flower of each umbellet 

 abortive; fruit oblong; carpels with 4 rows of flat prickles, 

 and 3 intermediate, bri.stly ribs. 



The Greek name of the Carrot. Cal. 5-toothed. Pet. emarginate with an 

 inflected point, the 2 outer ones often largest and deeply 2-cleft. Each car- 

 pel with 5 primary ribs, of which 3 are on the back, and 2 on the commissure, 

 and 4 secondary ones, all bristly. — Biennial herbs. 



D. Caro'ta. 



Stem hispid; petioles nerved beneath; haves tripinnate or pinnatifid, the 

 segments linear, acute ; umbels dense, concave. The word kar in Celtic sig- 

 nifies red, hence carrot. It is occasionally found wild in fields and by road 

 sides. Root fusiform. Stem 2—3 feet high, branching. Leaves numerous, 

 divided in a thrice pinnatifid manner, pale green. Umbels large and very 

 compact, with white flowers, blooming all summer. Cultivation has produced 

 several varieties. Carrot. 



3. SlUM. 



Involucres general and partial, the bracts many and entire ; 



fruit nearly oval ; carpels with 5 obtusish ribs and several vit- 



tas in the intervals; petals obcordate with an inflexed point. 



Celtic sun, water; that is, a genus of aquatic plants. — Perennial, leaves 

 pinnately divided. 



1. S. LATIFO'UUM. 



Leaves pinnate ; leaflets oblong-lanceolate, acutely serrate ; stem sulcate- 

 angular. A tall plant, in swamps and ditches. Stem 3 feet high, hollow, 

 smooth, with 7 deep furrows and prominent angles. Leaflets equally serrate, 

 in about 4 pairs with an odd one, those submerged, if any, pinnatifid. Leaf- 

 stalks ezribracing the stem at base. Umbels large, with numerous, small, 

 white flowers. July. Aug. Water Parsnep. 



2. S. LINEA're. T. S^- G. S. latifolium. /3. lineare. B. 

 Leaves pinnate ; leaflets linear, finely serrate ; bracts of the involucre linear- 

 lanceolate ; calyx teeth minute ; fruit obovate. In swamps. Stem three feet 

 high, furrowed and angled as the above plant, which it so much resembles in 

 its general aspect, as to have been generally, and perhaps correctly, consid- 

 ered only a variety. 



^ 4. CRYPTOTiE'NIA. 



Involucres 0; involucels few-leaved; margin of the calyx 

 obsolete; fruit linear-oblong or elliptic-oblong; carpels with 

 5 obtuse ribs; villas very narrow, twice as many as the ribs.
