If thestalks themselves are branched, the inflorescence is a is common in the grasses, the Vine, and the Olive. Ingrasses it is a panicle of spikelets instead of single flowers. The spike and raceme have a lengthened axis. A capi-tulum or flower head has a shortened axis and sessile flowers,as in the Everlasting family and Protea ; for here what lookslike a single flower is really a cluster of many flowers.
