Question

• A. Euphorbiaceae
• B. Moraceae
• C. Musaceae
• D. Lamiaceae

Answer 1

The correct option is D Lamiaceae

The term inflorescence refers to the group or cluster of flowers arranged on a stem or on an arrangement of branches. While there are number of simple and compound inflorescence, verticellaster is a special type of inflorescence where at each node of the stem two axillary opposite cymose inflorescences develop on either side. The cyme in the axil of each leaf, starts as a dichasial cyme but subsequently become monochasial scorpioid cyme. The cyme bends round the stem on either side and meets a similar cyme from the opposite side, bringing about a cluster of flowers at each node. This type of inflorescence is commonly found in Lamiaceae. Very often verticillasters with reduced bracts form an inflorescence commonly called as a spike.
Therefore, the correct answer is option D.
