Horticultural Society in July last, when it received the silver 
Knightian medal. 
The genus Nolana, as at present constituted, includes 
plants so different from each other in structure and general 
appearance that, considering the principles adopted in the 
classification of the Convolvulaceous, Boraginaceous, and 
other allied orders, it is necessary to break it up into 
several genera, for which good characters will be found in 
the very remarkable fruit, and probably in the flowers also, 
whenever an opportunity shall occur for examining them in a 
fresh state. 
If we regard Nolana prostrata as the original species of 
Nolana, we shall find that its distinctive character resides in 
the regular combination of its twenty ovaries into five nuts or 
drupes, each of which is four-celled. 
But there is another group, consisting principally of shrubs, 
in which the ovaries are very irregularly combined, so that 
while some of the nuts or drupes are four or more celled, 
others have not more than one, two, or three cells. They 
may be conveniently separated under the name of Alona (the 
anagram of Nolana). 
Corresponding with these in the irregular condition of the 
fruit, but not having more than eight or ten ovaries in com- 
bination, are two singular plants with all the habit of shrubby 
Salsolas, and a very small hypocrateriform corolla. They 
may be named Dolia (from doXuos, deceptive); they being one 
thing, and looking like another. 
On the other hand, in Nolana paradoxa and atriplicifolia 
there is a complete breaking up of the twenty ovaries into so 
many independent drupes. Those species constitute a group 
bearing the same relation to the other genera as Malope to 
its neighbouring Malvacezm. The name Sorema (from opos; 
a heap,) may be applied to them. 
Finally, under the name of Aplocarya (e7Aoos, simple, 
and kapva, a nut,) it will be desirable to station a singular 
scrubby shrub, in which the ovaries are five in number, and 
altogether simple.
