TRIBE XI. 



THAPSIE'JE. Fruit compressed from the back ; mericarps with 5 

 filiform primary ribs, which are now and then bristly : lateral ones 

 seated in the jlat commissure ; secondary 4 : inner ones of these 

 Jiliform, and the outer ones or all are winged : wings undivided, 

 hence the fruit is either 8-ninged, or furnished with 2 wings on 

 each side. Seed flattish, or teretely convex, flat in front. 



124 THA'PSIA. Margin of calyx 5-toothed. Petals elliptic, 

 entire, with an inflexed or involute point ; 2 lateral secondary 

 ribs winged, hence the fruit is 2-winged on each side ; furrows 

 under the secondary ribs furnished with 1 vitta each. Carpo- 

 phore bipartite. Seed flattish. Involucra and involucels want- 

 ing, or of few leaves. Flowers yellow. 



125 CYMO'PTERUS. Calyx minutely 5-toothed. Petalsround- 

 ish-oval, inflexed at the apex. Fruit nearly elliptic, compressed, 

 7-8-winged, from all the secondary ribs being winged; wings 

 undulated ; furrows flat, 1-nerved ; commissure naked, 3-striped. 

 Carpophore not separable from the mericarps. Involucra want- 

 ing ; involucels dimidiate, 5-7-parted. 



126 LASERPI'TIUM. Margin of calyx 5-toothed (f. 55. C./.).

 (f. 55. C. i.). Fruit compressed from the back (f. 55. C. g.), 

 or nearly terete, 8-winged, in consequence of the 8 secondary 



nerves being winged ; vittae 1 in each furrow, unde r the secon 

 dary ribs. Carpophore free, bipartite (f. 55. C. k.~). Involucra 

 and involucels of many leaves. 



127 LOPHOSCIA'DIUM. Margin of calyx 5-toothed. Petals 

 elliptic, entire, acuminated, involute at the apex (f. 55. B. rf.). 

 Fruit compressed (f. 55. B. e.) on the back ; the 2 lateral second- 

 ary ribs expanded into a subserrated wing each : the 2 dorsal ones 

 expanded into an interrupted wing each, at first sight appearing 

 like retrograde scales (f. 55. B. e.~). Involucra of 5-7 ovate- 

 lanceolate leaves (f. 55. B. a.); involucels of 5-7 narrower leaves 

 (f. 55. B. &.). Flowers yellow. 



128 MELANOSELINOM. Margin of calyx 5-toothed. Petals 

 obovate, emarginate, with a reflexed point. Fruit compressed

TRIBE XII. 



DAUCI'NE.E. Fruit lenticularly compressed from the back ; 

 mericarps with 5 bristly, Jiliform, primary ribs ; lateral ones of 

 these seated in the flat commissure, as in Thapsiece ; and with 4

 prickles free, or joined into a wing. Seeds flattish, or subsemi- 

 terete, or convex on the back, and flatfish in front. 



129 ARTE'DIA. Margin of calyx obsolete. Petals obovate, 

 emarginate, with an inflexed point : those on the outer part of 

 the umbel radiating and bipartite. Secondary ribs 4 : the 2 inner

 Leaves of involucra and involucels divided into linear lobes. 



130 ORLA'YA. Margin of calyx 5-toothed. Petals obovate, 

 emarginate, with an inflexed point : those in the ray of the umbel 

 profoundly bifid. Secondary ribs of fruit furnished with 2 or 3 

 rows of prickles, outer ones more prominent, or a little winged ;
