Many thanks Saroj ji.

I had done some study / checking on the internet.

Let me copy-paste whatever information I had collected here.

Distinct differences between Gonostegia bennettiana var. longifolia VERSUS Gonostegia hirta

While

Gonostegia bennettiana var. longifolia and Gonostegia hirta (Hairy Pouzolz's Bush) are related, they are visually and structurally distinct species within the same genus.

Visual Comparison

Feature	G. bennettiana var. longifolia	G. hirta
Stem Shape	Generally cylindrical or slightly angled.	Distinctly 4-angled towards the tip.
Leaf Base	Usually tapering (attenuate) or rounded.	Heart-shaped (cordate) or rounded.
Leaf Veins	Primarily 3-veined from the base.	Can be 3- or 5-veined from the base.
Leaf Texture	Membranous and minutely hairy (puberulous).	Herbaceous or thinly papery; upper surface is often bristly.
Growth Habit	Prostrate, creeping herb.	Prostrate to sub-erect, often longer (up to 100 cm).

Key Identification Differences

• The Stem: If you see a sharp, 4-angled stem near the top, it is almost certainly G. hirta. G. bennettiana stems are typically more rounded.
• The Leaf Base: Look at where the leaf meets the stalk. G. hirta leaves often "hug" the stem with a heart-shaped base, whereas var. longifolia leaves tend to be more slender and tapered at both ends.
• The Hair: G. hirta has a "rougher" feel due to its bristly hairs, giving it the common name "Hairy Pouzolz's Bush".
