46 APPENDIX. 



the inclusion of tlie Nolanace<2^ is necessarily a combination of 

 contradictory characters^ repeating and increasing all the defects 

 of his predecessors. 



I will here recapitulate the more essential points suggested on 

 a former occasion, when upon the principle then recommended, 

 the Solanal alliance, excluding entirely the Nolanace(B, but in- 

 cluding the ScrophulaTiace(£, will consist of individuals, marked by 

 the leading characters there enumerated [huj. op. i. 166.). Among 

 these, the Solanace(B mil embx'ace those genera with a monope- 

 talous corolla^ having a 5-, rarely 4-partite border, the lobes of 

 which (even under the unusual circumstance of the tube being 

 oblique) are nearly regular and equal, and their margins always 

 valvate orinduplicato-valvate in aestivation : epipetalous stamens, 

 alternate with, and equal to the number of the lobes, sometimes 

 unequal in length and size, and the fifth very rarely sterile ; 

 anthers introrse, bursting by longitudinal slits or apical pores ; 

 an ovarium most generally 2-celled, rarely 3- to 5-locular, with 

 a simple style and a 2-lobed or clavate stigma, often hollow j a 

 fruit either capsular or baccate, 2-locular, rarely more- celled 

 from the increment of the placentae, albuminous seeds with an 

 embryo, in the suborder CurvembryecBy always slender, terete, and 

 curved in a more or less annular or spiral form, in the suborder 



temhry 



cr 



not to the base, but to the basal angle of the seed, and turned 

 away to some short distance from the hilum, which is generally 

 lateral and somewhat marginal, but never basal. They consist 

 of plants, with alternate, often geminate, rarely pinnatifid leaves, 

 with an inflorescence sometimes axillary, but more generally a 

 little extra-axillary, or lateral, either single or fasciculated, or in 

 different modifications of the cyme, panicle or corymb, under a 

 mode of development called centrifugal. 



The ScrophulanacecB will consist of those genera, possessing a 

 tubular corolla, more or less curved and irregular, with a 4- or 

 5-partite border, the lobes of which are generally unequal and 

 bilabiate, and decidedly imbricate, never valvate, in aestivation; 

 stamens two or four, didynamous, rarely five, or with a rudi- 

 mentary fifth ; anthers always introrse ; an ovarium most gene- 

 rally bilocular, a simple style, with a stigma more or less bila- 

 biate or 2-lobed j fruit almost always capsular, in a very few 

 cases baccate, 2-locular, rarely more- celled, bursting in different 

 ways, with placentae proceeding from the dissepiment. Seeds 

 albuminous, with an embryo quite straight, or but little curved, 

 generally with the radicle pointed towards a basal hilum : in one 

 solitary instance the embryo is perispherically curved, and in the 

 Rhimnthe^y by an al)normal extension of the podosperm ; the 

 hilum appears somewhat lateral. In this very natural family,
