Bupleurum salicifolium, commonly known as ‘anís de risco’
or ‘tabaibilla’, is a woody, evergreen shrub endemic to the Macaronesia
region, found naturally in the Canary Islands and Madeira archipelagos.
It is a glabrous, highly branched shrub that usually grows to between 1
and 2 metres in height.
The leaves are light green or glaucous in
colour, leathery in texture, linear-lanceolate in shape and have visible
parallel veins. Their resemblance to willow leaves gives rise to the
specific epithet salicifolium.
The flowers are grouped in terminal
inflorescences in the form of umbels, comprising between 10 and 20 small
flowers of a striking yellow or yellowish-green colour. It flowers
mainly between May and August.
It produces small, dark-coloured
(brown or black) dry fruits with clearly marked ribs when ripe.
The
species is divided into two distinct subspecies based on their
geographical distribution and leaf morphology:
Bupleurum salicifolium
subsp. salicifolium: Found on the islands of Madeira, Porto Santo, La
Gomera and El Hierro. Its leaves are noticeably wider (8 to 15 mm).
Bupleurum salicifolium subsp. aciphyllum: This is a species endemic
exclusively to the Canary Islands, found on all the islands of the
western and central provinces (Tenerife, La Palma, La Gomera, El Hierro
and Gran Canaria). It is characterised by its notably narrower and more
pointed leaves (3 to 5 mm wide).
It grows naturally in areas of
cliffs, scrubland and rocky slopes. Its altitude range extends from the
basal zone and coastal thermophilic forests to the laurel forest
(laurisilva/fayal-brezal) and pine forests, reaching altitudes of up to
1,200 metres on south-facing slopes.
