Grozd

Grozdasta cvast bagrema

Grozd ili racema (lat. racemus) je vrsta cvasti iz grupe jednostavnih racemoznih cvasti. Ove cvasti imaju dugačku glavnu osovinu na kojoj su drške sa cvijetovima. Peteljke na glavnoj osovini su približno iste dužine. Terminalni cvijet može, ali ne mora bitiprisutan, odnosno nije nužno da se formira. Cvjetovi u grozdu mogu da rastu na sve strane, ali on može biti i dvostran i jednostran (npr. kod vrste gladiola (Gladiolus imbricatus). Listići koji se nekada pojavljuju na glavnoj osovini ustvari su brakteje.[1][2]
