PLANTS JAVANIC^ RARIORES. 589 



genus Professor Lindley has lately considered generically 

 distinct from Incarvillea. But except those differences in 

 the seeds and calyx, which I have regarded, and still con- 

 sider, as only of sectional value, I find no other characters 

 whatever in the flower or fruit to justify the separation ; 

 for in both species of Amphicome, as in the original Incar- 

 villea, the ovarium as well as the capsule is certainly bilo- 

 cular, and not unilocular, as it is described in the species 

 figured in the ' Botanical Register ' (for 1838, t. -19), and 

 the two subgenera entirely agree in the peculiar structure 

 of the anthera, the spur of each of whose loculi originates 

 not on the back, but front of the cell, in the line of de- 

 hiscence, which it limits. 



The following characters of Gesneriacece, and of the [112 

 three tribes of which, according to my view, it consists, 

 may serve to distinguish the family from the nearly related 

 orders, and the tribes readily from each other. 



GESNERiACEiE, Bichard et de Jussieu. 



Calyx 5-divisus, sequalis (rar6 parum insequalis). Corolla 

 monopetala, irregularis, limbo 5-lobo, sestivatione imbricata. 

 Stamina antherifera 2 v. 4, cum v. absque quinti postici 

 rudiraento. Ovarium (liberum v. adnatum) uniloculare (nunc 

 approximatione placentarum quasi biloculare); basi disco 

 lobato v. indiviso cinctum ; placentis 2 parietalibus latera- 

 libus (ssepius bilamellosis) polyspermis ; ovulis anatropis. 

 Pericardium capsulare v. baccatum. Semina parva (raphe 

 nulla), albuminosa v. exalbuminosa ; albumine carnoso, 

 moUi, copioso v. parco. Embryo rectus, axilis, orthotropus, 

 dimidium albuminis dum adsit sequans v. superans. 



Herbse v. Suffrutices foliis simplicibus, indivisis, exsti- 

 pidatis, oppositis, vcrticillatis alternisve, saipius serraiis 

 crenatisve nunc integerrimis, in plerisque pube simplici, 

 acut(tv. capitata. Inflorescentia varia. 



GeSNERIEjE. 



Calyx cum ovario pliis minus connatus. Pericarpium 

 capsulare. Semina albumine copioso.
