		Definition of aril in English: arilnoun ˈarɪlˈerəl Botany An extra seed covering, typically coloured and hairy or fleshy, e.g. the red fleshy cup around a yew seed.  Example sentencesExamples -  Seeds from the fruits were collected and viable seeds were distinguished by the colour of the aril (red, as opposed to dark brown for aborted seeds).
 -  The fruits, about 6 cm in length, are red or yellow, and, when ripe, split to expose three shining black seeds surrounded by fleshy arils.
 -  But the fruit's clusters of arils - or seeds surrounded by a juicy sac - are protected by sections of white, pithy membrane.
 -  What are commonly thought of as spices today are a collection of seeds, berries, flowers, fruits, kernels, roots, rhizomes, leaves, arils, barks and saps that are used in cooking and food preparation.
 -  The frail, brown shell is marked with longitudinal ridges, sometimes having a whitish aril (seed coat) fixed to one end.
 
 
 Derivatives   adjective Botany  The migrant bird Tersina viridis utilizes arillate seeds of the Asian tree Michelia champaca.  Example sentencesExamples -  It was not possible to compare the removal and predation rates between arillate and non-arillate seeds due to the fast removal of the aril by invertebrates such as harvestmen, grasshoppers and especially ants.
 -  Experimental results with another bird-dispersed tree bearing arillate seeds, Clusia criuva, have further demonstrated that ant-induced seed movements can markedly affect seedling establishment in the Atlantic rainforest.
 -  In an arillate fruit, the aril is a fleshy outgrowth of the seed's own outer covering.
