I (erbaceous plants, often with a soft texture, and heavy Bmell, covered with glandular 



hairs, or quaternary vesicles. Leaves opposite or alternate, undividi 

 lobed, without Btipulea Flowers axillary, solitary, 

 or clustered, usually large, and furnished in many 

 cases with conspicuous bracts. Calyx divided into 5 



nearly equal pieces. Corolla monopetalous, hyp< 

 Dous, irregular ; the throat ventricose, the limb bUa- 

 biate, the lobes somewhat valvate in pestivation. Ifisk 

 bypogynous, fleshy, Bometimes glandular. Stamens 



didynanious, included within the tube, together with 

 a rudiment of a fifth. Anthers '.'-celled ; the con- 

 nective articulated with the filament, a little proloi 

 hey ond the cells, terminated by a gland. Ovary 

 seated in a glandular disk, 1-celled, formed of two 

 Carpellary leaves, anterior and posterior as regards 

 the axis, sometimes divided into 4 or li spurious cells 

 by the splitting of two placentas and the divergence 

 of their lobes ; ovules anatropal, either erect, or pen- 

 dulous, or horizontal, solitary, or '_', or several ; style 



1 ; Btigma divided. Fruit drupai us or capsular, 



valvular, or indehiscent, with from 2 to 6 ell-, which 

 are usually few-seeded when numerous, and many, 

 seeded only when two. Seeds 

 w inj^less : albumen none 



dons large, plano-convex 

 hilum. 



The only real differences that can he found between 

 these plants and Bignoniads consist in tlie parie- 

 tal placentse of the former, their wingless or nearly 

 wingless seeds, which are in most cases definite, and 

 Bometimes in their woody lobed placentse, which 

 spread and divide variously in the inside of the peri- 

 carp, so as to produce an apparently l or 6-celled 

 fruit out of a 1-celled ovary. Sesamum may be con- 

 sidered a transition from tl le to the other. From 



i iesnerworts they are readily known by the texture of 



their fruit, their large seeds, plano-convex cotyledons, 



and very short radicle. Calabashes are distinguished 



by their great succulent fruit and almond-like sei 



Endlicher rightly observes that Ih-own in forming 



his Pedalinje {Prodr. 51 9.), does net combine with 



them Sesamum ; neither, however, does he explain 



how they are to be distinguished ; but as usual, the 



extreme and studied conciseness of this learned man leavi - Ids i much 



in the dark as if the name of Sesanuun had not been mentioned. 



It is not a little remarkable that such observers as De Candolle ( /' 

 Endlicher (Linnaa, vii. p. 8.) should suppose the fruit of tl 

 5 or 4 carpels, a statement entirely opposed to both theorj and (act l( 

 posed of two anterior and posterior carpels, exactly as that of the otlh I :i tin- 



present Alliance. It is doubtless true that Martvnia has been da 



noii numerous, aim many -
