Justicia species ?
To me the plant seems to be Justicia gendarussa
The day before yesterday … sent me these two photographs in a separate mail and we had a little discussion. I didn’t know he also uploaded it in eFI. However, … also provided me the list of spp distributed in Bangladesh.
Since the species is a herb it is one of species number 2 to 6 of Flora of Pakistan – http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=116893#KEY-1-6 (as per list given by …).
I have seen none of those listed species. Without details of bracts, spike, calyx… as KEYed in FoP i am unable to identify the species.
Members who have more experience on various Justicia spp may help.
Justicia species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available)
Wallich cat. no. 2443 (see links below) is connected with two entries of FBI, J. quinqueangularis Koen. (ref. BP) and J. diffusa var. vahlii.
If bracts are obtuse or subacute this can be Justicia vahlii Roth.
I am also agree with …, we also discussed through another a-mail
