Rosaceae of Portugal

Family of major economic importance not only for its fruits but also for its ornamentals. Well-known edible fruits are very variable being drups (fleshy with a stone) as in apricot, cherry, nectarine, peach, plums, prune, almond; pomes as in apple, quince, pear, loquat; aggregates (with free carpels) as in blackberry, raspberry, strawberry. The beautiful tree Prunus lusitanica is widely planted as a hedge as are Spiraea, Cotoneaster, Pyracantha, Crataegus and some others. Rosa is the best-known ornamental species and there are many thousand hybrids and cultivars. Rose perfumes are made from rose oil, a mixture of essential oils obtained by steam distilling the crushed petals.
