Giertncr lias however subsequently asserted that such a 



dissepiment is present in Ricotia, and has given in his car- 

 pological work an engraving of its silicle, in which that 

 part is shown as complete and distinct as in Lunaria, only 

 not so conspicuously pedicled. Willdenow has replied, and 

 maintained that Gaertner has figured a silicle of Lu\ t arta 

 redivixa for one of Ricotia cegyptiaca. Dr. Roth, in his 

 " Catalecta botanica," rejoins in support of Gaertner, and 

 avers that the dissepiment is always present in the unripe 

 silicle, hut being of a very tender delicate substance, it 

 breaks from the frame of the suture, and adheres to the valve 

 opposite to that on which the seed is seen to lie, showing 

 itself in partially detached scaly fragments. But Gsrtner's 

 figure is plainly of a ripe silicle belonging to the present 

 plant (and not, as Willdenow gratuitously avers, to Lunauia 

 raliviva)\ in which, however, no one else pretends to have 

 seen a dissepiment in the state he has represented it. So 

 that we are to suppose either that he has met with an ano- 

 malous specimen, or (with less candour) that he has pre- 

 sented us with an offspring of his prepossession. Mr. 

 Brown, whose accuracy merits the greatest confidence, has 

 always found this part ultimately obliterated, although 

 clearly present in an early stage. 



Sir James Smith has recorded a new species (temiifolia) in 

 the first part of the second volume of the " Prodromus Flora; 

 grecie;" in a note on which Mr. Brown is made to say, that 

 44 the fruit of the genus is not constantly unilocular;" which 

 seems to us to be in no way the equivalent of what he has 

 said himself concerning that part, in the character we have 

 quoted from the Hortus Kewensis.
