UMBELLIFEROUS TRIBE. 279 



* A variety (D. maritimus), abundant on many parts 

 of the sea-coast, differs from the preceding in having 

 somewhat fleshy leaves, and in being destitute of the 

 central purple flower, or umbel. 



28. CAUCALIS (Bur-Parsley). 



1. C. daucoides (Small Bur-Parsley). Leaves re- 

 peatedly divided ; umbels of about 3 rays, without bracts ; 

 partial umbels of few flowers, with about 3 bracts. 

 Chalky fields, not common. A somewhat bushy plant, 

 nearly smooth, with a stem which is deeply furrowed and 

 hairy at the joints. The flowers, which are pinkish 

 white, grow both in lateral and terminal umbels, and 

 are succeeded by large prickly seeds. Fl. June. Annual. 



* C. latifolia (Great Bar-Parsley) was formerly not 

 uncommon in chalky fields in Cambridgeshire, but is 

 now extinct there. It is taller than the preceding, and 

 is well distinguished from it and all other British plants 

 of the tribe by its handsome, large, rose-coloured flowers. 



29. TORILIS (Hedge-Parsley). 



1. T. Anihriscus (Upright Hedge-Parsley). Leaves 

 twice pinnate ; leaflets narrow, sharply cut ; umbels 

 stalked ; general and partial bracts several. Hedges, 

 abundant. A tall slender plant 2 3 feet high, with a 

 solid rough stem, hairy leaves, and many-rayed umbels 

 of small white or pinkish flowers. The fruit is thickly 

 covered with incurved rigid bristles. Fl. July, August. 

 Annual. 



2. T. infesta (Spreading Hedge-Parsley). Leaves 

 twice pinnate ; leaflets oblong, sharply cut ; umbels 

 stalked ; general bracts 1 or 0, partial several. Hedges, 

 common. Smaller than* the last, 6 18 inches high, 

 with more branched stems and more rigid leaves. The 

 fruit is covered with spreading hooked bristles. Fl. 

 July, August. Annual.
