lanticum, Poir. suppl. 3. p. 304. Ligtisticum Fontanésii, Spreng. 
in Schultes, syst. 6. p. 565. Perhaps the furrows of the fruit 
are furnished with 1 or many vitte, and therefore may be either 
a species of Ligtisticum or Cnidium ; but the habit is that of 
Cnidium. ;

Selinum Canadénse, Michx. fl. bor. amer. 1. p. 155. A‘pium 
bipinnatum, Walt. carol. p. 115. The fruit is unknown, and 
therefore it is a doubtful species of Cnidium. Flowers white.

LXXIV. PETITIA (in honour of M. Felix Petit, author of 
a memoir on the genus Althénia, and who first made known the 
present plant by a figure and description). Gay, in ann. sc. nat. 
26. p. 219. ; 
Lin. syst. Pentándria, Digynia. Calyx toothless, Petals 
lanceolate, entire, with an involute point. Fruit oblong, crowned 
by the reflexed styles ; transverse section roundish-elliptic, fur- 
rowed on both sides, from the raphe being nearly central, not 
marginal; mericarps rather convex on the back, with 5 con- 
tiguous, thick, elevated, wingless, bluntly keeled ribs, therefore 
the transverse section is triangular, spongy inside ; lateral ribs 
not broader than the rest, nor marginal. Vittæ solitary in the 
furrows, which are narrow, and twin in the commissure. See 
adhering to the tegument, compressed, not angular.— A glabrous; 
green, biennial herb: with a very long, branched, thick root, 
which is spongy inside, and intercepted by transverse, mem- 
branous dissepiments. Stem short, nearly simple, thick, fistu- 
lar, leafy at the base, striated above, and scabrous at the stri@- 
` Leaves tripinnate; sheaths large; rachis smoothish ; lobes 
linear, scabrous on the margins, and on the dorsal nerve, Gt 
cronate at the apex. Umbels terminal, of many rays: rays a 
83, very rough, and very unequal: central ones much a 
shortest. Involucra wanting, rarely of 2 leaves ; involucels 0 
from 4-12 linear-subulate, quite entire leaves, which are muc 
shorter than the umbels. Flowers greenish. Stylopodium large. 
1 P. sca'sra (Gay, l. c.) ¢. H. Native of the ewe
