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.
