Scientific classification :
- Kingdom : plantae
- Division : tracheophyta
- class : Angiosperms
- subclass : Eudicots
- superorder : Asterids
- order : Asterales
- Family : Asteraceae
- Subfamily : carduoideae

-
Genus : Echinops.
An old world genus of more than 115 species of flowering plants in the
daisy family Asteraceae .
Distribution:
most common in the Eastern Mediterranean region.
Represented by at least 7 named and some unnamed species in Saudi
Arabia. Heemstra
lobed, the teeth or lobes spinous-tipped. Heads terminal and axillary, compound, each consistine of.
number of 1-flowered headlets sessile on a common subglobose to ellipsoid receptacle and decidno individually from the receptacle. Common involucre of the head reduced to small narrow bracts refleve
and concealed under the compound head at base. Each headlet with its own involucre (the nartial
involucre); the outer involucre of numerous bristles or narrow pales (constituting the “pencil") and of
many inner imbricate involucral bracts; the involucral bracts peristent, coriacous, green, purple to bluish-
violet, the outer narrow, narrowly spathulate above, pinnatley long-ciliate near base, the other gradually
becoming longer subulate or attenuate-acerose; some of the bracts transformed into long spines (the
headlets with the long spines called cornigerous headlets); 5 innermost free or united and then forming a
tube. Florets hermaphrodite, perfect, tubular, 5-lobed, blue or greyish to white. Anthers with setose-hairy
basal appendages, bluish-grey; filaments glabrous. Style with a ring of minute hairs below the branches.
Achenes elongate, terete to quadrangular, densely hairy. Pappus of numerous short setae or narrow scales,
distinct or connate forming a narrow crown.
