C. munbyana<\/strong> (Boiss. & Reut.) Stapf [Polygala munbyana<\/em> Boiss. & Reut., Polygaloides munbyana<\/em> (Boiss. &
\nReut.) O. Schwarz], glabrescent, with quadrangular stems, shortly winged, and with flowers pink or yellow; endemic to the littoral and sublittoral mountains of NE Morocco (from littoral Bokkoyas towards the E) and the coastal mountains of central-western Algeria.<\/p>\n

C. webbiana<\/strong> (Coss.) Stapf [Polygala webbiana <\/em>Coss., Polygaloides webbiana <\/em>(Coss.) O. Schwarz], easily differentiated by its densely pubescent branchlets; present in southern Spain (Malaga) and NW Morocco (calcareous mountains of the western Rif and, although rarer, also in the Middle Atlas, in Bab Metik).<\/p>\n

In Algeria C. munbyana <\/em>is included in the List of protected non cultivated flora (Executive Decree 12-03 on 4-Jan-2012).<\/p>\n","protected":false},"template":"","short_name":"Chamaebuxus","name_html":"Chamaebuxus<\/strong>Tourn.","short_description":"","references":"","custom_author":"A.
