What forms do compound flowers come in?

• A. Umbel, Head, And Panicle
• B. Raceme, Spike, And Corymb
• C. Solitary Bloom
• D. Inflorescence Types

Answer: (B)

Compound flowers are inflorescences—multiple flowers arranged as a single unit rather than a single blossom. The forms most commonly described for these arrangements are raceme, spike, and corymb. In a raceme, flowers sit on short stalks along a central axis, with the oldest at the base and new ones toward the tip. In a spike, the flowers are directly attached to the axis with no stalks, producing a continuous column of flowers. In a corymb, flowers are on stalks of different lengths so the upper ones reach a similar level, forming a flat or rounded top. These patterns contrast with other inflorescence forms like umbels (flower stalks spreading from a common point like an umbrella), heads (a dense cluster of sessile flowers forming a single head), or panicles (branched racemes). A solitary bloom, by contrast, is just a single flower, not a grouped inflorescence.
