Familia
APIACEAE
Hierba negrilla
Bupleurum semicompositum, commonly known as ‘hierba negrilla’ or, by its English name, ‘dwarf hare’s ear’, is a small annual herbaceous plant belonging to the Apiaceae family. It is a slender, delicate species, native mainly to the Mediterranean and Macaronesian regions.
It is a very small therophyte (annual) plant, usually measuring between 2 and 35 centimetres in height. It has slender stems barely 1 mm in diameter with long internodes and highly branched stems.
The leaves are glaucous green (greyish-blue), linear or narrowly lanceolate, up to 25 mm in length. They have parallel veins and a subamplexicaul base (partially clasping the stem).
The inflorescence consists of umbels comprising between 2 and 12 notably unequal rays. Its flowers are minute and yellowish-green in colour.
The fruits are small (1–2.5 mm), subglobose mericarps, characterised by being covered with small whitish papillae and having barely perceptible ribs.
This species thrives in arid, sunny environments exposed to maritime influences or in continental steppes. It is commonly found on sandy soils, calcareous therophytic grasslands, slopes and low dunes. It is also found on semi-saline soils, in marshes and along the edges of brackish lagoons.
Geographically, it is widespread throughout the Mediterranean basin and the Irano-Turanian region, and is native to most of the Canary Islands, where it is commonly found in low-lying areas and volcanic ash deposits near the coast.
