To solve this matching question, we need to understand the specific botanical terms and how they relate to the given plants and flowers:
Vexillary Aestivation: This is a type of flower petal arrangement found in the family Fabaceae (Leguminosae), particularly known in plants like Pea. Here, one large petal, called the standard, overlaps the two lateral petals, known as wings, which in turn overlap the two smallest anterior petals called the keels. Thus, this matches with Pea (III).
Epipetalous Stamens: Stamens that are attached to the petals are called epipetalous. This is characteristic of the Brinjal, where the stamens are fused to the corolla. Thus, this matches with Brinjal (I).
Epiphyllous Stamens: Stamens that arise from the perianth (which includes the sepals and petals). This is characteristic of the Lily family, where stamens are attached to the tepals (similar to petals and sepals). Thus, this matches with Lily (IV).
Perigynous Flower: In these flowers, the ovary is partially submerged and surrounded by a floral cup (hypanthium), giving it a half-inferior position. This feature is seen in the Peach. Thus, this matches with Peach (II).
Based on the above reasoning, the correct matching for the options given is:
List-I
List-II
A. Vexillary aestivation
III. Pea
B. Epipetalous stamens
I. Brinjal
C. Epiphyllous stamens
IV. Lily
D. Perigynous flower
II. Peach
Thus, the correct answer is A-III, B-I, C-IV, D-II.
