DIVERSIFICATION IN LASIA SPINOSA (LOUR.) THWAITES TWO MORPHOTYPES EXISTING WITHIN ASSAM BASED ON MORPHO METRIC AND ISSR MARKER ANALYSIS

Lasia spinosa or Unicorn plant is an important tropical spinous rhizomatous herb. This one of the native species Assam used as vegetable and in Ayurvedic medicines. There are two distinct morphological types spinosa: Morphotype-I i.e.having dissected laminal hastate form Morphotype- II i.e. form. The current study revealed that physical anatomical parameters assent with genetic diversity through molecular data analysis. vein type, however, was discovered to be jumbled craspedodromous semi-craspedodromous morphotypes (I, II), respectively. Least variance forms observing leaf architecture. small changes petioles' roots' internal architecture between morphotypes. To do a phylogenetic analysis spinosa, ISSR-PCR product approximately 56% polymorphisms (i.e32 out 57 bands which each other).
