moft of the wholeforne fruits, and the' thir- 
teenth chiefly coniifts of fuch plants as are 
poisonous; and it is curious to remark how 
juftly the infertion of. the ftamens into the 
calyx may be relied on as an indication of a 
fruit free from noxious qualities. In the 
Primus genus there are fome fbecies, as the 
padus and lauro-cerafus, in which every part, 
except their pulpy fruit, is poifonous ; and of 
that we may eat with fafety. This mark is 
alfo worth attending to in' the plants of other 
claffes. In the clafs Pentandria Monogynia 
there are many fruits, the juices of which are 
highly deleterious; but in Bibes (currant and 
goofeherry^ we find a wholeforne and grate- 
ful fruit, indicated by the circumftance of the 
infertion of the ftamens into the calyx. This 
charafieriftic diftinftion of the clafs Icofandria 
is alfo vifible when the fruits are ripe, their 
calyx frequently remaining like a little crown 
on their top, and, while in a frcfli ft ate, a 
ftdlful botanift may diftinguilh the infertion 
of the ftamens qn the inner part of it's divi- 
fions. The flowers of the twelfth clafs, Ico- 
fdndria, have a hollow calyx of one leaf, the 
corol fattened by it's claws to the infide of 
the calyx, and; as was before obferved, the 
ftamens
