consider that of Iberis, in wliicli I can find no })eculiarity, 

 as deviating from that structure.^ 



Luna HI A libyca of Viviani' is the second phmt of Cru- 

 ciferae on which I have some observations to offer. This 

 species was described and figured, by the author here 

 quoted, in 18.24, from specimens cohected in 1817 by 

 Delhi Ceha. The specimens in the herbarium were found 

 near Tripoli, where the plant had also been observed in 

 1819 by ^Ir. llitchie, who referred it to Lunaria, and 

 remarked that the calyx was persistent. Professor Sprengel, 

 in his ' Systcma Vcgctaljihum,' considers it a species of 

 Farsetia. 



Tliat this phmt ought not to be associated cither witli 

 the original species of Lunaria, or with Savignya, as now 

 constituted, is sufficiently evident. And if it is to be in- 

 chided in Farsetia, it can only be on the grounds of its 

 having a sessile silicule, with compressed valves, an inde- 

 finite number of seeds in each cell, and accumbent cotyle- 

 dons. But in these respects it accords equally with 

 Meniocus, a genus proposed by ]\L Desvaux, and with 

 some hesitation received by M. De Candolle, and with 

 Schivereckia of Andrzejowski, which he has also adopted.
