Study Notes
Malvaceae Family
- Also known as the Mallow family.
- Key Features:
- Monothecous and tetrasporangiate stamens.
- Many endospermic seeds in the fruit.
- Polypetalous corolla.
- Some members may lack epicalyx.
- Examples:
- Hibiscus
- Gossypium (Cotton)
- Abelmoschus (Okra)
- Floral Characteristics:
- Actinomorphic flowers
- Pentamerous calyx and corolla
- Twisted corolla
- Exstipulated leaves
- Staminal tube
- Polyadelphous stamens
- Epipetalous stamens
- Schizocarpic fruits and capsules.
- Superior Ovary, Hypogynous flowers.
Other Families and Characteristics:
- Fabaceae (Pea family):
- Basal placentation
- Liliaceae (Lily family):
- Bisporangiate Stamens
- Epiphyllous Stamens
- Poaceae (Grass family):
- Marginal Placentation
- Lodicules
- Spikelet
Incorrect Matches:
- Binola oil is not from the Cruciferae family. It's from the Malvaceae family, specifically the Gossypium genus (Cotton).
- Marginal placentation is associated with the Poaceae family (Grass family), not the Malvaceae family.
- **The Sunflower (Helianthus) belongs to the Asteraceae family (Compositae), not the Malvaceae family. **
- The Malvaceae family does have a capsule fruit, so this statement is correct.
Other Key Points
- **The floral formula provides information about the presence of extra whorls, epipetalous stamens, and monothecous anthers. **
- The floral formula does not include information about the superior gynoecium. This is a general characteristic of the Malvaceae family.
- The Malvaceae family does not have valvate aestivation in the calyx. The corolla is the whorl that may exhibit valvate aestivation. The calyx is mainly twisted.
