Umbellated imflourascence is with in racemose( With the main axis shortemed) . Not a seperate type.
six major types of inflorescence. A 1. Racemose Inflorescence 2. Cymose Inflorescence 3. Compound 4. Cyathium 5. Verticillaster 6. Hypanthodium.
Racemose Inflorescence: In this type of inflorescence the main axis does not end in a flower, but it grows continuously and develops flowers on its lateral sides in acropetal succession (i.e., the lower or outer flowers are older than the upper or inner ones). The various forms of racemose inflorescence may be described under three heads.
They are as follows:
(i) With the main axis elongated, i.e., (a) raceme; (b) spike; (c) spikelets; (d) catkin and (e) spadix.
(ii) With the main axis shortened, i.e., (i) corymb and (ii) umbel.
(iii) With the main axis flattened, i.e., capitulum or head.
An umbel is an inflorascence that consists of a number of short flower stalks (called pedicels) which spread from a common point, somewhat like umbrella ribs. The arrangement can vary from being flat topped to almost spherical. Umbels can be simple or compound. The secondary umbels of compound umbels are known as umbellules or umbellets
