thorn. This is not the firft fhrub, or tree 
(for when it (lands fmgle it generally de- 
ferves the latter appellation) that we have 
examined belonging to this Clafs Icofandria. 
In March, you remember, we met with the 
Prunus Jpinofa in bloflbm -, but it is of the 
Order Monogynia. 
Let us now examine that yellow '*- 
flower which grows fo profufely among ?" 
the green corn. The petals of the 
flower being four, equal, and in the 
form of a crofs, tell us, at once, that it 
is of that natural clafs called by Ray, 
Siliquofei by Tournefort, Cruciform! , 
and by Linnaeus, ^etradynamla^ from 
from Tecr<ra quatuor and Awap? poten- 
tia. The Stamina, you obferve, are fix, 
four long and two fhort ones: at the 
bafe of the latter, there is a neclarife- 
rous gland, which, that it may not be 
comprefled, obliges two of thejlamtna 
to make a curve j this circumftance ren- 
ders them fhorter than the other four. 
The Orders in this Clafs are Siliculofa, 
feeds in a broad pod or pouch, and Siliquofie, 
feeds in a long pod. But thefe diftinftions 
are of no ufe in the prefent ftate of this 
R 2 plant.
