OF this genus we have already figured fix different {pecies ; 
this is another newly difcovered one, which, like moft of its 
kind, difplays its beauties chiefly in the night. It is the only 
one, as far as we yet know, that has white bloffoms ;_ thefe, 
when firft expanded, are beautifully fo, but in the morning they 
change to a purple colour, fade, and their place is fupplied by — 
a frefh fucceffion. In this remarkable change of colour, it | 
bears fome affinity to the Gixothera anomala, which may be 
confidered as ftrengthening our opinion that the latter plant 
belongs to this genus rather than to that of Gaura. The 
_ GQnotbera tetraptera is a native of Mexico, its duration as 
yet not certainly afcertained, but may be treated as a tender 
annual; and fuch plants as do not flower the firft year, may 
be preferved under glaffes through the winter. It was raifed 
from feeds fent by Mr. Donn, from Cambridge; but was pro- 
bably firft introduced into this country from feeds fent to the 
Marchionefs of Bure, by Prof. Orteca, of Madrid. —
