Detailed Matching Explanation
Floral formulas use symbols: ⊕ (actinomorphic), ⚥ (bisexual), K (calyx), C (corolla), A (androecium), G (gynoecium); numbers in () indicate fusion.
-
A. ⊕ ⚥ P(5) A₅ G(2) → III. Chenopodiaceae: P(5) denotes perianth (tepals); typical for this family (e.g., Beta); 5 free tepals, 5 stamens, 2 carpels.
-
B. ⊕ ⚥ Epi K₅–₇ K(5) C₅ A(∞) G(5) → IV. Malvaceae: Epicalyx (bracts K₅₇), calyx K(5), corolla C5, monadelphous A∞, 5 carpels (e.g., Hibiscus).
-
C. ⊕ ⚥ K(5) C(5) A₅ G(2) → II. Solanaceae: Gamosepalous K(5), gamopetalous C(5), epipetalous A5, bicarpellary G(2) (e.g., Petunia, Datura).
-
D. ⊕ ⚥ K₅ C₅ A₅+₅ G(3) → I. Caryophyllaceae: 5 sepals, 5 petals, A10 (5+5 whorls), 3-5 carpels (often G(2-5)); e.g., Dianthus.
