1. My vtws communis. Linn.'? 
This differs slightly from the European forms, by the ends of the young branches being covered with a 
rusty pubescence, and by the larger fruit (5-6 lines in diameter). We have not seen the flower, but so far 
as we can judge by the remains of the calyx-limb, the segments are obtuse, and often four or five in number. 
The structure of the seed is that of a true Myrtus.
