Gertner has however subsequently asserted that such a 
dissepiment is present in Rrcorra, 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 Gertner has figured a silicle of Lunarra 
. rediviva for one of Ricotra @gyptiaca. Dr. Roth, in his 
“« Catalecta botanica,” rejoins in support of Gaertner, and 
avers that the dissepiment is always present in the unripe 
silicle, but 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 Gzrtner’s 
figure is plainly of a ripe silicle belonging to the present 
plant (and not, as Willdenow gratuitously avers, to Lunarta 
redtviva); 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, 
Browa, 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 (tenuifolia) in 
the first part of the second volume of the ‘“ Prodromus Florez 
grece;” in anote on which Mr. Brown is made to say, that 
“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. 
The seed’ should be sown in a sheltered border, where the 
plants are to remain. This will come up in the autumn, 
and the plants will flower early in the summer. It may be 
also sown in the spring; when the plants will flower later. 
The drawing was made at the nursery of Messrs. Lee and
