UMBELLIFER^:. 



compressed, girded by a smooth, winged, flattened, or rather con- 

 vex, dilated, entire margin. Mericarps nith SJiliform ribs, rarely 

 winged; lateral ribs contiguous to the dilated margin, or lost in it. 

 Raphe marginal, hence the fruit is only furnished with 1 ning on 

 each side, not nith Z wings, as in the last tribe, where the raphe 

 is central. Seed flattened, or rather convex on the back. 



91 OPO'PANAX. Margin of calyx obsolete. Petals roundish, 

 entire, involute, with an acutish point. Stylopodium broad, thick ; 

 styles very short ; mericarps with 3 dorsal, filiform, very slender 

 ribs : the 2 lateral ones wanting, or not distinct from the margin ; 

 vittse 3 in each furrow, and C-10 in the commissure. Seed flat. 

 Involucra and involucels of many leaves. Flowers yellow. 



92 FE'RULA. Margin of calyx with 5 short teeth. Petals 

 ovate, entire, with an ascending or incurved point. Fruit 

 girded by a dilated flat margin ; mericarps with 3 dorsal filiform 

 ribs : the 2 lateral ones very obsolete, or not distinct from the 

 dilated margin ; vittae 3 or more in the dorsal furrows, and 4 or 

 more in the commissure. Seed flat. Carpophore bipartite. 

 Involucra and involucels variable. Flowers yellow. 



93 DORE'MA. The large, cup-shaped, epigynous disk, and 

 the solitary vittae in the furrows of the fruit, distinguish this 

 genus from Ferula and Opopanax. The flowers being com- 

 pletely sessile is also a remarkable character. 



94 ERIOSY'NAPHE. Calyx bluntly 5-toothed. Petals ovate, 

 entire, with a short, incurved point (f. 56. E. /.). Fruit com- 

 pressed (f. 56. E. k.) from the back, girded by a thickish margin : 

 the 3 dorsal ribs filiform : and the 2 lateral ones running into 

 the thickish margin, which is spongy inside ; furrows broad, 

 2-3-striped, bearing 2-3 vittae in each ; and the commissure is 

 without vittae, but marked with a middle nerve and 2 marginal 

 ones, rather hollow and tomentose between the nerves. Seed 

 flattish. Involucra and involucels wanting. Flowers yellow. 



95 PALI'MBIA. Margin of calyx obsolete. Petals elliptic, 

 with an acute inflexed point. Fruit oblong or oval. Mericarps 

 compressed from the back : with 5 filiform, bluntish ribs : 2 mar- 

 ginal ones a little broader than the rest ; vittae 3 in each furrow, 

 and 2 broad ones in the commissure. Seed oblong, free, striped. 

 Involucrum few-leaved or wanting. Flowers cream-coloured. 



96 PEUCEDA'NUM. Margin of calyx 5-toothed. Petals obo- 

 vate, emarginate, or entire, with an inflexed point. Fruit girded 

 by a flat margin ; the 3 dorsal ribs filiform : and the 2 lateral 

 ones more obsolete, contiguous to the dilated margin ; vittae in 

 each furrow usually 1, and in the commissure 2. Carpophore 

 bipartite. Seed flat in front. Involucra variable in the different 

 species ; involucels of many leaves. 



97 IMPERATORIA. All as in Peucedanum, but the margin of the 

 calyx is obsolete. Involucra wanting ; involucels of few leaves. 



98 CALLI'SACE. Margin of calyx rather 5-toothed, or nearly 

 obsolete. Petals oval, with an incurved point. Fruit nearly 

 orbicular, emarginate at the base, with a winged margin ; the 3 

 dorsal ribs obtuse and nerve-formed : the 2 lateral ones ex- 

 panded into wings, which lie over the whole surface : vittae 1 

 in each furrow, and 1 on each side of the commissure. Forks 

 of carpophore adhering to the mericarps. Involucra wanting, or 

 of few leaves ; involucels of many setaceous leaves.

99 BU V BON. Margin of calyx obsolete. Petals obovate, en- 

 tire, with an acute involute point. Fruit girded by a flattened, 

 dilated margin ; the 3 intermediate ribs filiform, and the 2 lateral 

 ones going into the margins ; vittae covering the whole seed, 4 

 dorsal and 2 in the commissure. Carpophore bipartite. Seed 

 flat in front and convex on the back. Cape shrubs. Involucra 

 and involucels of many leaves. Flowers greenish yellow. 



100 ANE'THUM. Margin of calyx obsolete. Petals roundish, 

 entire, with a rather square refuse point. Fruit girded by a flat 

 margin ; the 3 intermediate ribs acutely keeled, and the 2 lateral 

 ones more obsolete, and running into the margin ; vittae broad, 

 solitary in the furrows, and filling them, and twin in the commis- 

 sure. Seed rather convex on the back. Involucra and invo- 

 lucels wanting. Flowers yellow. 



101 CORTIA. Teeth of calyx elongated, acute. Petals lan- 

 ceolate, acuminated, entire. Stylopodium conical ; styles di- 

 verging. Fruit elliptic, rather retuse at both ends ; ribs winged : 

 lateral one the broadest ; vittse 1 in each furrow, and 2 in the 

 commissure, which is flat. Seed flattish. Involucra of 2-3 mul- 

 tifid leaves ; involucels of 5 linear, entire, or 2-3-cleft leaves. 



102 CAPNOPHY'LLUM. Margin of calyx obsolete. Petals ob- 

 long, rather emarginate, tapering into an inflexed acumen. Fruit 

 girded by a flat, dilated margin ; the 3 intermediate ribs thickish, 

 keeled, rather flexuous, tubercular : the 2 lateral ones going 

 into the dilated margin ; vittae 1 in each furrow, and 2 in the 

 commissure. Seed rather convex on the back. Involucra and 

 involucels of 3-6 leaves. 



103 TIEDEMA'NNIA. Margin of calyx 5-toothed (f. 64. a.). 

 Petals acuminated, reflexed. Fruit nearly ovate (f. 64. c.); 

 mericarps with 5 filiform, subcarinated, approximate ribs : lateral 

 ones dilated into a membranous margin, which is nearly the 

 breadth of the fruit ; vittae solitary in the furrows, and filling 

 them, and twin in the commissure. Carpophore bipartite. 

 Seed flat. Involucra and involucels of 4-5 subulate leaves. 



104 ARCIIEMO'RA. Margin of calyx 5-toothed. Petals ob- 

 cordate, with an inflexed point. Fruit compressed from the back, 

 oval or obovate ; mericarps with 5 filiform, rather keeled, ap- 

 proximate ribs : lateral ribs dilated into a broad membrane ; 

 vittae solitary in the furrows, and filling them, and twin in the 

 commissure. Carpophore bipartite. Seed flattened. Involucra 

 wanting or few-leaved ; involucels of many leaves. 



105 PASTINA'CA. Margin of calyx obsolete, or minutely den- 

 ticulated. Petals roundish, entire, involute, with a broad retuse 

 point. Fruit compressed from the back, girded by a flat dilated 

 margin : the 3 intermediate ribs filiform, equidistant : lateral ones 

 contiguous to the dilated margin ; vittse linear, acute, hardly 

 shorter than the ribs, solitary in the furrows, and twin or more in 

 the commissure. Carpophore bipartite. Seed flattened. In- 

 volucra and involucels wanting or few-leaved. Flowers yellow. 



106 LEIOTULUS. Teeth of calyx obsolete. Petals roundish, 

 entire, involute, with a broad retuse segment. Fruit compressed, 

 with a thickened dilated smooth margin ; the 3 intermediate 

 ribs approximate, and the 2 lateral ones marginal and remote ; 

 vittae 1 in each furrow, filiform, distant in the commissure. In- 

 volucra wanting ; involucels of a few very fine leaves.
