350 Mr. Don’s Description of a new Genus belonging to 
the form of its corolla, essentially distinguish it from both these 
genera. Both Maurandia and Antirrhinum have their seeds 
covered by a thick spongy testa, which is very much wrinkled, 
and resembles in a remarkable degree the testa of the curious 
cruciferous genus Parrya of Mr. Brown. ‘This character is also 
met with in all those genera which are intimately allied to An- 
tirrhinum; and it appears to me to be of sufficient importance 
to warrant their being regarded as a separate section, which may 
be denominated Antirrhinee. Chelone, on account of its flat 
seeds and foliaceous cotyledons, will constitute another section 
of the order, forming the link of affinity between it and Bignoni- 
aceé, from which it principally differs in the direction of its 
seeds, and in the presence of albumen. Sesamum corresponds 
with the latter family in the absence of albumen; but in the 
form and direction of its seeds it is closely allied to Chelone, 
from which it is however essentially distinguished in the struc- 
ture of its capsule, the absence of albumen, and by having the 
cells of its anthers parallel. It may therefore be considered as 
forming, together with Martynia and Craniolaria, a distinct na- 
tural group, as has already been suggested by Mr. Brown. 
In Scrophularia the upper lip of the corolla is so much more 
developed than the lower one as to give the flower the appear- 
ance of being resupinate. The anthers of this genus differ very 
materially in structure from those of every other genus of the 
order; they are unilocular, and open by means of a transverse 
fissure, and the cell is attached along its whole length to the 
summit of the filament, in which particular it recedes from the 
usual form of the one-lobed anther. 
A number of other scctions equally distinct might be indi- 
cated, the adoption of which would greatly facilitate a know- 
ledge of the genera of this extensive order. In a practical 
point of view, the advantages arising from the division of
