puberula (sensu latiore). In the circumstances, however, I prefer to leave 
open the question as to origin and position of this species. 
I insert here a sketch-map of the Canarian Archipelago, which may 
serve as a summary of our present knowledge of the distribution of the 
Statices of the Nobiles group.

Distribution of the Statices of the Nobiles group — 
1. Statice arbor ea. 2. Statice macrophylla. 3. Statice imbricafa. 
4. Statice brassicifolia. 5. Statice puberula. 
The figures in brackets mark stations from which the species has disappeared in recent times. 
As there exist excellent figures and fairly good descriptions of all the 
species mentioned above (with the exception of the dubious Statice 
Preattxii), I do not consider it necessary to describe them over again in 
extenso ; but I thought it might be useful to add short diagnoses put 
together in the form of a key, a sort of condensed descriptions fractionnees 
et classees 1 . They would bring out the salient characters of the species, 
and at the same time facilitate identification. 
Key. 
Ultimate divisions of the panicle winged, with the wings widened upwards and 
produced into auricles ; pubescence, if any, uniform. 
Glabrous or nearly so (only the ultimate or subultimate divisions of 
the panicle sometimes sparingly pubescent) ; primary axis of the in- 
florescence and its primary divisions wingless or very narrowly winged ; 
auricles below the ‘spicae’ usually produced into fine, often sickle- 
shaped points ; inner bracts with distinct laterally-compressed, abruptly- 
ending keel and narrow scarious margin ; leaves distinctly petioled, 
blades often slightly undulate and shallowly sinuate at the decurrent 
base. 
Bare main stem several feet high; leaves to over 30 cm. by 
13 cm. S. arborea (typica). 
Bare main stem very short, branches from the ground or almost 
so; leaves rarely over 10 cm. by 5 cm. S. arborea f. frutescens.
