(After Xiedenzu.) The flowers are sometimes soHtary m the leaf-axils, as in Myrtle {Jly/iu-s communis) and Guava (Psidium Guayava): but generally in cvmose. more rarely racemose, branched in- florescences. They are bisexual, regular. cycUc and generally epigvnous (as in M^Ttle. and Psidium. fig. 188). but imion between receptacle and ovary is not always complete so that various degrees of perigyny occm. The most general f\ rrangement of the flower is expressed by the formula S-i-5,.
