( Scapicephalus ) rosulatus ; d , D. racemosus and D. trollii . Habitat: —Elevation (2190–) 2430–3880 m , subalpine; locally frequent in forest clearings [ Abies webbiana (Wall. ex D.Don) Lindl. ], moist scrub, meadows [ Juniperus squamata Buch. -Ham., Bergenia stracheyi (Hook.f. & Thomson) Engl. , Kobresia nepalensis (Nees) Kük. ] and among rocks. Notes: Decalepidanthus elongatus is apparently restricted to a small stretch of land on the outer (south) slopes of the far western Himalaya, west to Hazara; a single literature record for Swat requires confirmation. With the possible exception of some doubtful specimens or populations from the upper Kaghan valley, its distribution is sharply separated from that of D. echioides to the north of the main Himalayan range.
