of Borrer; the Pedunculate laterales of my * Manual.’ | "These possess 
two nectaries (as he calls the “ glands” at the base of the germen and 
stamens of English authors), two or three free stamens, catkin- scales 
of uniform colour, and convolute vernation. These nectaries are blunt 
plates, one placed within the catkin-scale and next to it, the other on 
the opposite side of the germen or stamens. Dumortier then included 
Amerina his present subgenus Lycus, the Pentandre of Borrer, 
which has an urceolate nectary, much like the so-called ** cup-shaped” 
perianth of Populus, from the middle of which the germen or stamens 
spring, 4—8 stamens, catkin-scales of uniform colour, and vernation con- 
volute. 
2. VgTRIX, the Repentes, Rosmarinifolie, Vacciniifolia, Cineree, 
and JVigricantes, of Borrer's latest views. ese have one simple 
cuneate nectary on the opposite side from the scale, two free stamens 
with fuscous-yellow spent anthers, catkin-scales discoloured at the end, 
and equitant vernation. 
3. VrwEN, the Osiers; the Viminales of Borrer, with one simple 
nectary, two monadelphous stamens with yellow spent anthers, and re- 
volute vernation. 
ELICE (as he now calls it), the Purpuree of Borrer, possess- 
ing a cuneate simple nectary, one stamen with a four-celled anther, or 
two monadelphous stamens with purple anthers becoming black when 
n and equitant vernation. 
5. CHAMÆTIA, of which I have not seen his characters. It includes 
the “alpine Willows;” the Myrsinites, Reticulate, and Herbacea of 
Borrer; the Pedunculate terminales of my ‘Manual.’ Its characters 
appear to be, nectary of two opposite plates, (but Fries justly remarks 
** nectario in vivo ulterius probe observanda. Duo petit Dumortier, 4) 
two stamens, and inflorescence from the terminal or subterminal buds. 
We want much information in this group; the structure of the nectary 
is uncertain, the vernation is apparently unknown. But the subgenus 
is well marked by the position of the inflorescence upon Jong leafy, per 
sistent, terminal or subterminal shoots. In all the rest of the genus the 
inflorescence is manifestly lateral. It is possible that Dumortier =
