This interesting little species of Ruta, so unlike all the — 
others with which I am acquainted, in the general appear- 
ance and color of the flowers, has, nevertheless, the same struc- 
ture of leaves, and the same smell with the rest of its congeners. 
The number of the parts in the species of this genus seems to 
be very variable ; but the stamens appear to me to be more fre- 
quently eight than ten. In regard to the generic character, 
too, there seems to be some obscurity ; at least in this species I 
do not find “ puncta mellifera,” which are described: as existing 
on the receptacle. ‘There is indeed a remarkable gland or nec- 
tary surrounding the base of the germen, as in the other species 
of Ruta; but here there are no distinct pores. The germen is 
pedunculated, which I do not find to be the case with other 
Rute, and the styles, though united, so as to appear but one, are 
in reality four, or as many as there are lobes to the : germen ; and 
these are frequently separated as the lobes diverge, in the cap- 
sules’ advancing to maturity. It is the only pees weld which 
‘Tam acquainted that has white flowers. 
The present individual flowered in the month of June of — 
this year in the garden of my valued friend P. Nrrnt, Esq. at 
Canonmills, near Edinburgh, and was raised, among other rari- 
ties, trom seeds which were received from Nepaul. ,
