Answer 2

The type of anther in Leucas aspera is didynamous  and connivent(2+2).

• Leucas aspera , commonly known as thumba/thumbai belongs to the family Lamiaceae an annual herb distributed throughout India.
• Didynamous stamens are the characteristic of the  Lamiaceae family, consisting of 4 stamens with unequal lengths.
• One pair of stamen is long while the other is short usually the upper pair.
• Epipetalous stamens: Stamens are attatched to the petals of the flower.
• Connivent anthers are those that are converging into contact but not fused.
• Anther cells seem to be divaricating(branching off).
• This anther arrangement helps in effective insect pollination(entomophily) and prevents self-pollination to a certain extent.
