* All the unibels peduncled. 

 t Root-Jibres filiform. 



1. OE. aiigulo§a, G-riseb. 2^ Stem tall, angled, solid. Leaves 

 of two sorts, the lowest tripinnatisect into cuneate-ovate, pinnatifid or 

 parted segments, the upper pinnatisect into elongated, linear lobes. 

 Rays of umbel 8-12, somewhat thickened in fruit ; petals moderately 

 radiating ; fruiting umbellets contracted, hemispherical, somewhat con- 

 Ycx above ; /'r?*i^s scarcely more than ,002 long, the outer as long as 

 thickened pedicel — June — Moist places ; middle zone of Lebanon. 



1 1 Root fibres thickened, or filiform with tiiberous nodules near tips . 



2. €E. media, Griseb. If .4 to .5. Tubers sessile, oblong or cy- 

 lindrical. Leaves of one sort, 1-2-pinnatisect into linear lobes, those of 

 upper leaves a little longer. Rays 5-8 ; fruiting umbellets compact, 

 hemispherical; fruit short-cylindrical — Spring — El-Huleh ; Leba- 

 non, and northward. 



3. CE. pinipinelloides, L. If .4 to .5. Root-fibres ending in 

 ovate or nearly globular tubers. Leaves of two sorts, the radical bipin- 

 natisect into ovate-ctcneate, dentate or incised lobes ; the middle and 

 upper [)innatisect into short-linear or long-linear lobes, or undivided^ 

 linear. Rays 4-8 ; fruiting umbellets compact, flat-topped ; fruit 

 cylindrical — May and June — Wet fields and swamps ; middle Leba- 

 non, Jjattakia, and northward. Very near QG. angulosa, Griseb. 



* * Central umbellet sessile ; marginal sterile forming an involucre. 

 Rootfibres cylindrical, thickened. 



4. <E. prolifera, L. If .3 to .5. Leaves of one hind bipinna- 

 tisect into cwieate-ovate and cuneate-obovate, crenate-dentate segments. 

 Hermaphrodite umbels with 5-7, marginal, staminate, abortive umbellets, 

 the hardened, flat, irregularly lobed rays of which form an involucre 

 around the central, fertile, hemispherical umbellet ; fruit sessile, prisma- 

 tic — Spring — Wet places ; common along coast, and in central plains, 

 and lower mountain regions to 800 m. 



40. SESEL.I, L. Sesbli. 



Calyx-teeth 5, thickish. Fruit nearly terete, ovate, or oblong , 

 styles deflexed, inserted on conical stylopodia. Ribs of mericarps 5, 

 slightly elevated, or prominent, thick, the lateral at margin, some- 

 times longer. Intervals (in ours) 1-vittate. Albumen semiterete — 

 Herbs, usually perennial, with (in ours) white flowers. 



5. L<ibaiioti§, L. If .8 to 1.5 ; stem angled, sparingly branch- 

 ed. Leaves 2-3-pinnatisect into oblong-ovate, obtuse or acute lobes, 

 .003 to .005 long ; umbels convex, m;iny-rayed; bracts of involucre and 

 involucel numerous, linear-subulate, membranous-margined, ciliate, at 

 length deflexed ; fruit ovate, .003 long, hirsute ; ribs prominent, ob- 

 tuse — June — Amanus (1500 m.), and northward. 



41. CXIDIUM, Guss. Cnidium.
