As per efi thread: H. verticillatus has cladodes 2.5cm or longer, stiff, very sharp pointed bifid or rarely trifid ...accidental prick is very painful, stinging. Plant about a meter tall or less, stout. Flowers light to deep shade of violet. In H. tentaculatus cladodes are up to 1.5cm, soft, hairy, tip inconspicuously bifid, non-prickly. Three varieties can be recognised by cladodes... In var. plumosa cladodes are covered in dense soft white hairs, inflorescence which is actually terminal part of stem and branches, looking like plume. In var. neilgherryensis terminal spike of cladodes and flowers is densely packed, meaning by, internodes are very small. And of course cladodes not plumose. Var. tentaculatus seen in suitable habitat in Surat, is having cladodes sparsely hairy, nodes widely spaced. Cladodes are pointed upwards in Haplanthodes tentaculatus (Nees) Majumdar or its two other varieties, while these are pointed either straight or downwards in Haplanthodes verticillatus (Roxb.) R.B.Majumdar Haplanthodes species in India:
