ILLUSTRATIONS OF INDIAN BOTANY- 



these, than by description only, I have in the accompanying plates given analyses of three of its. 

 four sub-orders, and of 6 of the 12 tribes under which DC. has distributed the species. The 

 remainder, not having representatives in the Indian flora, are excluded. The following are 

 Dc Ciiudolle's characters of the sub-orders and tribes here shown, with the names of the genera 

 employed to represent them. 



( 



Flowers isomerous ; aestivation of the corolla valvate. 



Capsule didymous, many-seeded, seeds wingless ; embryo small ; cotyledons scarcely con- 

 spicuous. Herbaceous plants; leaves sometimes exstipulate. Mitrasackme Mitreola, 



Sub-order II. Strychne.e. Flowers isomerouSj aestivation of the corolla valvate. Embryo con- 

 spicuous. Trees or shrubs. 



Tribe IL EustrychnecB. Berry or drupe two-celled, many-seeded ; sometimes by abortion 

 one-celled and one-seeded. Seeds peltate, wingless. Strychnos. 



Tribe JTT. Gardneriece. Berry 2-celled and 2-seeded. Seed peltate, wingless. Gardneria. 



Tribe IV. AntoniecB. Capsule 2-celled, bipartible, septicidal, dehiscing from the apex. 

 Seed few in each cell, peltate, winged. Aiitonia, 



Sub-order III. liOGANiEiE. Flowers isomerous, corolla convolute in aestivation. Shrubs or herbs. 



Stipules sometimes wanting. 



Tribe X. Fagrceaceoo. Fruit baccate. Seeds numerous, wingless. Fagrcca. 



Tribe XL GcErtnercB. Ovules anatropous. Berry dicoccous, cocci 1-seeded. Seed erect 

 from the base. Gcertnera. 



A comparison of the characters of the Tribes, here placed in strong contrast, will show at 

 once how difficult an order this must be to deal with. The first tribe is closely related to 

 GeniianecE in habit, structure and properties ; the second and third to Jpocynacew ; the fourth 

 leaning towards BignoneacecB in its winged seed, and Sesamece, in the peculiarly inflexed margins 

 of the valves of the capsule : the tenth approaches Bignoneacece] in the form of its flowers, 



the latter.
