XVlii A FLORA OF GIBRALTAR AND THE NEIGHBOURHOOD 
Cork Wood and Alcadeza Crags being gt: where: new records 
can readily be made. It contains about 1020 native species, of _ 
which over 140 do not occur for certain elsewhere in our region. 
The list is too long to detail, but the following, in addition to 
ts — do not occur elsewhere in the province, those in 
roman type not being recorded from Spain, while those marked ?

District III. Subdistrict ii. AnGecrras.—This subdistrict, of 
lve ole lf square miles, is the only one, except that o 
Gibraltar, which contains mountains of over “an 
range behind Algeciras is usually called the Sierra de Palm 
the 8. de Luna, but I have been unable to verify that these retail 
are used locally, nor to which portions of the range they apply. 
Debeaux usually, though not eso writes of the 8. de Luna 
as in the Los Barrios district, but moras certainly lie south of the 
Palmones River, and are iechew < e northern end of the range. 
I have called the whole range, of which I have personally only 
worked the — nearest to Algeciras, the “ Mountains behind 
Algeciras,” or simply ‘“ Mountains.” They are mostly covered 
with cork and ok trees, with shrubs of the Cistacee, Legumini- 
fere, and Ericacee, the undergrowth being ericetal. The valleys 
are well-watered, and produce thany moisture-loving plants, but 
as the elevation — the vegetation becomes more xero- 
philous, and nothing of an alpine or see ep nature is found, 
unless Corbularia Bulbiseaaaes be so classified. The lower hills 
about Algeciras and the higher ones hans Carnero Point have 
a somewhat similar flora to that of “es of the same nature 
about San Roque, but 76 — Point species found elsewhere 
only on the Rock reappear, e. g. Silene obtusfolia and Asteriscus 
maritimus. There are fapat lls at Sandy B. ~~ south of Algeciras, 
and from about a mile north of the town up to the Palmones 
River there are extensive sands, much of shink is cultivated for 
vegetables. The river is tidal and its muddy shores support a 
few halophilous plants.
