80 SILA'US. Margin of calyx obsolete. Petals obovate- 

 oblong, entire, or rather emarginate, with an inflexed point ; ribs

 so close together as to appear one ; commissure furnished with 

 4-6 vittae. Involucra wanting or of few leaves ; involucels of 

 many leaves. Flowers cream-coloured or greenish. 



81 WALLRO'THIA. Calycine teeth 5, ovate-lanceolate, acute 

 (f. 56. A. 6.). Petals elliptic, entire, acute at both ends (f. 56. 

 A, d,). Mericarps with rather prominent, equal ribs ; vittae 

 numerous in the furrows. Involucra of 1-3 unequal leaves; 

 involucels of 5-8 unequal leaves. 



82 ME'UM. Margin of calyx obsolete. Petals entire, ellip- 

 tic, acute at both ends. Mericarps with rather prominent, equal, 

 keeled ribs ; vittee many in each furrow, and 6-8 in the commis- 

 sure. Involucra wanting ; involucels of many leaves. 



83 GA'YA. Margin of calyx obsolete. Petals obovate, more 

 or less emarginate, with a broad inflexed point. Fruit oval, a

VOL. HI. 



the base, at equal distances, obtuse ; vittae none. Carpophore 

 bipartite. Involucra few-leaved. 



84 CONIOSELINUM. Margin of calyx obsolete. Petals ob- 

 cordate or obovate, with an inflexed point. Styles at length 

 reflexed. Fruit compressed or convex from the back ; ribs 

 winged : lateral ones twice the breadth of the rest ; vittae 3 in 

 each furrow, but in the dorsal furrows sometimes only 2 : and 4-8 

 unequal ones in the commissure ; carpophore bipartite. Invo- 

 lucra wanting, or of few leaves ; involucels of 5-7 linear-subu- 

 late leaves. 



85 CRI'THMUM. Margin of calyx obsolete. Petals roundish, 

 entire, involute, with an obovate point. Mericarps with 5 ele- 

 vated, sharp, somewhat winged ribs : the lateral ribs a little 

 broader than the rest ; pericarp spongy from large cells. Invo- 

 lucra and involucels of many leaves. Seed semi-terete, consti- 

 tuting a distinct nucleus, covered with copious vittae. 



TRIBE VI. 



ANGELI'CE.*:. Fruit compressed from the back, girded by 2 

 wings on each side, from the raphe being central, or nearly so ; 

 mericarps furnished with 5 ribs: the 3 dorsal ribs Jiliform or
