The subject of the accompanying plate is an example of an 
essentially South African group, inhabiting northern Africa, 
and is further remarkable as forming a connecting link be- 
tween the vegetation of the three very remote geographical 
botanical districts of South Africa, the Canary Islands, and 
Arabia. In so far as I am aware, no Senecio of this habit has 
been found elsewhere in Northern, nor anywhere in Tropical 
Africa. Like many outlying species of genera with restricted 
limits, it departs a little from the characters of its immediate 
congeners; in this case in its remarkably odorous flowers, whose 
heliotrope-like scent is the chief merit the plant possesses as 
an object of cultivation to any but the lover of the curious. 
Senecio pteroneura is a native of rocky and sandy hills on 
the Maroccan coast near Mogador, where it forms a lax 
leafless shrub, that supports itself in thickets of Retama and 
JANUARY Ist, 1872.
