As we learned
Types of inflorescence -
Racemose - The main axis does not end in a flower but continues to grow. The development of flowers is acropetal (old flowers arrange on lower side and young one on upper side). The opening of flowers is centripetal
Raceme: When main axis (peduncle) and flowers are pedicellate, acropetally. Ex: Mustard, Radish
When peduncle is branched and each branch bear flower is called compound raceme or panicle
Spike - Peduncle has bisexual and sessible flowers. Ex: Achyranthes. When penducle is branched and each branch bear spike, then each branch having flower is called spikelet and this arrangement is called spike and spikelet. Ex: Wheat (Graminae family)
Catkin - Peduncle is long, weak and flowers are sessile and unisexual. eg. Mulberry, Betula, Oak
Corymb - Peduncle is short and all flowers are present at same level because the lower flower has much long pedicle. eg. Ex: Capsella, Iberis, cauliflower
Umbel - All flowers arise from same point. At the base of flower stalk there is a whorl of bracts forming the involucre. eg. Cautella, coriander, cuminum
Spike with fleshy axis and having both male and female flowers. Surrounded by large coloured bract called spathe. eg. Maize and Banana
