62371 $120^{\circ}$ phyllotaxy is found in:

1 tristichous

2 pentastichous

3 distichous

4 octastichous

Explanation:

A
$120^{\circ}$ phyllotaxy is found in tristichous. In tristichous phyllotaxy, there are three leaves in one spiral.
The mode of arrangement in the 1st, 4th, 7th and 10 th leaf remains in one row while the 3rd, 6th, 9th and 12th in the second row and 2nd, 5th, 8th and 11th are in the third row. For ex. Cyperus rotundus.

62374 Alternate phyllotaxy in which the sixth leaf lies above the first leaf after completing two circles is known as:

1 distichous

2 tristichous

3 pentastichous

4 octastichous

Explanation:

C
Phyllotaxy is defined as the arrangement of leaves or mature leaves on branches or the stem in a distinct pattern. Pentastichous phyllotaxy is also called as $2 / 5$ phyllotaxy. It is seen in Hibiscus. In this the sixth leaf base lies above the first one after completing two circles similarly the seventh leaf base lies above the second leaf base.
