32. Euphorbia cognata (Klotzsch & Garcke) Boiss. in DC., Prodr. 15(2): 120. 1862. Rech. f. & Schiman-Czeika in Rech. f., Fl. Iran 6: 29.1964; Stewart, Ann. Cat. Vasc. Pl. W. Pak. & Kashm. 448. 1972.


  • ?Euphorbia cashmeriana Royle
  • Euphorbia consanguinea Klotzsch
  • Euphorbia pilosa var cognata (Klotzsch & Garcke) Hook. f.
  • Tithymalus cognatus Klotzsch & Garcke

    Very like Euphorbia carnigera but plant more generally pilose, leaves quite entire and fruits only sparingly covered with shortly cylindrical processes.

    Holotype: ‘Himalaya’, W. Hoffmeister s.n. (B).

    Distribution: Afghanistan, Pakistan (Chitral, Waziristan). 9500'/2900 m.

    Euphorbia cognate may really only represent a local variant of the much more wide-spread Euphorbia cornigem. Specimens cited under the latter include intermediates between the two.

    Typical Euphorbia pilosa is a Siberian and Mongolian plant, and, although listed by Stewart (Ann. Cat. Vasc. Pl. W. Pak. & Kashm. 451. 1972), it does not occur in Pakistan.
