jiartiiil of many loaves sliortcr than the flowers. Distinguislied 
iroin the preeeiling hy its j)et., uniform leaflets, and want of a 
general involuere. — Many authors refer the English ])lant to CE. 
siluifolia (llieh.) whieh has an enlarged eallous base to its fr. 
aeeording to Koch and Grisebaeh. The nomenelature cannot be 
settled without rij)c fruit of the English plant. — In freshwater 
marshes. P. VI. E.

oblong-wedgeshaped variously cut those of the upjjer 1. narrower, 
fr. cylindrical oblong striated longer than its pedicel. — E. B. 
2dld. — St. 3 — 5 feet high, much branched. L. large, leaflets 
broad. Involuci’es various in number and shape. — [CE. apiifolia 
has narrower and more divided upper 1. according to a Corsican 
specimen.] — Wet places. P. V^II.

6. CE. Phellandrium (L.); st. erect: base fusiform, 1. tripinnate, 
leaflets ovate pinuatifld cut sjn-eading, of the submersed 1. multifld 
with capillary diverging segments, umbels lateral opposite to the 
leaves, fr. ovate. — E.B.GS4. — St. 2 — 3 feet high, very thick below, 
stoloniferous. Segments of the 1. numerous, fine, acute, pale 
gi’een ; submersed 1. dark green. Probably, as suggestedby Koch, 
the flowering root dies each year, but the plant is continued by 
the offsets. — In the water of ditches and ponds. 13. ? /3. P. ?

7. CE. fluviatilis (Golem.) ; st. floating, 1. bipinnate, leafl. 
simple or pinnatifid, of the submersed 1. cuneate cut pellucid with 
many parallel nerves, umbels lateral opj)osite to the 1., fr. broadly

well marked by the leafl. of its submersed 1. being divided into 
flngerlike acute broadly linear parallel segments deeply incised 
at the end. Leafl. of the upper 1. broader than those of CE.
