As coming from a comparatively low level, in a thoroughly 
tropical and indeed a very hot archipelago, Campanula 
Jacobea forms a remarkable exception to the rule that the 
genus to which it belongs is eminently one of temperate 
and, indeed, cold latitudes. It is certainly one of the last 
vegetable forms that might be expected to occur in the 
torrid and generally arid Cape de Verd Islands, in lat. 15° N., 
and which forms geographically an insular continuation of 
the Saharan region. In this, as in other respects of its 
botany, the Cape de Verd Islands display an affinity with 
the Floras of the temperate Atlantic Islands to the north- 
ward of them (Canaries, Madeira, and Azores), which is 
totally out of harmony with their physical conditions, and 
thus affords one of the strongest proofs known of a previous 
land-connexion, whose effects on the Flora have not been 
obliterated by subsequent geographical segregation. The 
late Mr. P, B. Webb, who published the first Florale of the 
Cape de Verds, founded principally on the collections made 
by Christian Smith in 1816, by myself in 1839, and by 
Vogel in 1841, and which appeared in the “ Niger Flora,” 
states that nearly one-fifth of the species then known belong 
to Canarian genera or forms, only a tenth to the Arabo-
