Long name !!
Two days ago got this query .
Spent some time over it and found the key !
In simple words ...
Stem non - prickly = A. manihot subsp. manihot (Himalayan subsp.)
Stem prickly = A. manihot subsp. tetraphylla ---->
subsp. tetraphylla var. tetraphylla .......epicalyx lobes covered with small soft hairs
subsp. tetraphylla var. pungens .......epicalyx lobes covered in long prickly hairs .
Specimen I collected in Surat today(14 10 2019) morning is definitely Abelmoschus manihot subsp. tetraphylla var. tetraphylla !
Point worth mentioning is , like many many species of the family , flowers bloom in the morning light yellow to yellow ,
they turn pink by evening . Literature I perused , I got this hint that even learned people have confusion on flower color .
Leaf shape is very variable and doesn"t matter in ID process ......leaves are dark green , entire to variably lobed ......it is the epicalyx...broad , long , red ...
beautiful ...prominently displayed on top of branches .... key to ID .......epicalyx lobes fall in fruit .......it is persistent in fruit in A. angulosus .
(Abelmoschus is separated from Hibiscus on basis of calyx...splits on one side in flowering , falls off with corolla on withering )
Use .....to clean Jaggery ....it is crushed along with sugarcane !!! Age old technique of farmers all over India .
