L. Boulos (1973) distinguished subsp.
asper (annuals with leaves mostly cauline, cypselae margins little or not at all curved and/or ciliate, and one pair of chromosomes with small satellites) from subsp.
glaucescens (biennials with leaves mostly in rosettes, leaves mostly stiffer and more prickly than in subsp.
asper, cypselae with curved, ciliate margins, and two pairs of chromosomes with large satellites) and noted that the two subspecies are morphologically rather difficult to distinguish if the specimen in hand lacks the rootstock or stem base.
According to H. N. Barber (1941), crosses between Sonchus asper and S. oleraceus resulted in sterile hybrids.

Sonchus asper
provided by wikipedia EN
Sonchus asper, the prickly sow-thistle,[2] rough milk thistle,[3] spiny sowthistle,[4] sharp-fringed sow thistle, or spiny-leaved sow thistle, is a widespread flowering plant in the tribe Cichorieae within the family Asteraceae.
Description
Sonchus asper is an annual or biennial herb sometimes reaching a height of 200 centimetres (6.6 ft) with spiny leaves and yellow flowers resembling those of the dandelion. The leaves are bluish-green, simple, lanceolate, with wavy and sometimes lobed margins, covered in spines on both the margins and beneath. The base of the leaf surrounds the stem. The leaves and stems emit a milky sap when cut. One plant will produce several flat-topped arrays of flower heads, each head containing numerous yellow ray flowers but no disc flowers.[5][6]
Distribution
Sonchus asper is native to Europe, North Africa, and western Asia. It has also become naturalized on other continents and is regarded as a noxious, invasive weed in many places. Its edible leaves make a palatable and nutritious leaf vegetable.[7][8][9][10][11]
It is found in cultivated soil, pastures, roadsides, edges of yards, vacant lots, construction sites, waste areas and in grasslands.[12]
