with that of Onagrariæ by an inferior germen (incorporated 
with what by some is termed the tube of the calyx), a parted 
calyx, a corolla of several petals inserted at the outer rim 
of the top of the germen alternately with the leaflets of the 
calyx, by stamens inserted on the same level with the pe- 
tals, by a single style, and a many-seed capsular fruit; on 
the other hand the Loasec differ from the Onagrarie by the 
indefinite number of the stamens, by a fruit with one cell 
that opens at the upper part only by three shallow valves, 
and by the seed being borne on three vertical receptacles 
attached at equal distances along the inner wall of the 
capsule. 
We believe our plant will prove to be annual. The stem 
was rather more than a foot high. The pubescence which 
covers it is of two kinds, the one of longer stouter straight 
unjointed transparent pricklelike -hairs with a small bag or 
vesicle at the base containing the liquid for transfusion 
through the sting when in action, the other of pliant, softish, 
jointed hairs without any vesicle, and quite harmless. The 
stigma attributed to the genus has been always described as 
single, but in our plant the style was terminated by three 
recurvedly spreading subulate ones rather shorter than the 
column itself, and reaching a little beyond the stamens. 
Each of the five leaflets that compose the stamineous crown 
was furnished at the base, at equal distances on the out- 
side, with three narrowly ligulate diffusely spreading ap- 
pendages nearly as long as the leaflet itself. 
* Mr. Lambert has engravings which represent fifteen 
species of the genus, most of them unrecorded : they form 
a part of the plates intended for the forthcoming volume of 
the Flora Peruviaua. Twelve species have been repre- 
sented from the dried subject by engravings appended to a 
per on the order Loaseæ inserted by M. De Jussieu in the 
pa 
Annales du Musée.
