PuATE XXX. 
PEUCEDANUM venetum, Koch. 
Natural Order UMBELLIFERA. 
Grn. Cuar.— Perennial, rarely annual. Leaves pinnately, or 3-nately 
compound. Umbels compound, many-rayed; bracts few or 0; bracteoles 
many or 0; flowers white, yellow, or pink, often polygamous. Calyx- 
teeth 0, or small. Petals with an inflexed, often 2-fid point. Disk-lobes 
small; margin often expanded, undulate. Fruit ovoid, oblong or sub- 
orbicular, much dorsally compressed, commissure very broad; carpels 
flattish, lateral primary ridges of each forming flat contiguous wings, 
dorsal and intermediate filiform; vitte 1-3 in each interstice. Seed 
nearly flat."—Hooker, Student's Flora of Brit. Is. p. 168. 
Spec. Coar.—L lowers white, arranged in several umbels forming a pani- 
culate inflorescence; rays of umbel rough along inner face. Bracts of 
general involucre 5-8, spreading or sub-reflexed. Styles long, at length 
reflexed and equalling or exceeding one-third of fruit. Leaves dark-green 
and shining above, 3-pinnate, leaflets triangular-ovate, ultimate divisions 
lanceolate or linear lanceolate, scabrous at edge.

Hasrrat.—Mentone valley, Mentone, in a shady part, where I gathered 
the specimen figured on December 11th 1865. (Figs. 3, 4, and 5 are, 
however, from a specimen in the Kew Herbarium, gathered at Prades in 
the Pyrenées Orientales.) 
Remarks.—Peucedanum venetum, Koch., is nearly related on the one 
hand to P. alsaticum, Linn., which is distinguished, however, by its 
yellowish flowers, short styles, and smooth rays of umbel, and on the 
other to P. austriacum, Koch., in which the bracts of the general involucre 
are much more numerous and reflexed. 
There are specimens of P. venetum in the herbarium at Kew, gathered 
near Prades in the Pyrenées Orientales (name of collector and date not 
given), this forming an isolated and hitherto unrecorded station on the 
extreme west of its range; from Outre Rhdéne, about half-way between 
St. Maurice and Martigny, where it was detected by E. Thomas, who 
communicated the specimen to M. J. Gay; and from the Val Vestino in 
the Western Tyrol (Porta). 
MM. Grenier and Godron give but one station for P. venetum in France— 
viz. the Chartreuse de Valbonne. It appears that this species is found here
