Long-Spine Thistle is an extremely variable plant, 4-10 ft tall, with
spreading branches. White to purplish-white flower-heads, clustered or
solitary, are borne on leafless stalks, or are stalkless. They are 2-3.8
cm across, with florets about 1.6 cm. There are lanceshaped bracts ending
in erect or recurved spines. Stalkless leaves are pinnately lobed, with
margins having very long, stout spines. Leaves are hairless above and
cottony beneath. Stems are hairy and leafy. Long-Spine Thistle is found in
the Himalayas, from Afghanistan to SW China, at altitudes of 1200-3300 m.
Flowering: May-August.
