Brassicaeae is one of the 15 most important plant families from an economic point of view. All cabbage cultivars (Portuguese cabbage, savoy cabbage, red cabbage, cauliflower, brussels sprouts, and broccoli) belong to this family, and to a single species, Brassica oleracea, from the Mediterranean region and southwest Europe. Other cultivated species belonging to this family are the rapeseed (Brassica napus) from which is extracted the rapeseed oil, watercress (Nasturtium officinale), radish (Raphanus sativus), mustard (Sinapis alba), rocket (Eruca sativa), horseradish (Armoracia rusticana), wasabi (Eutrema japonicum), and several other ornamentals such as hoary stocks (Mathiolla incana) and annual honesty (Lunaria annua). The bitter and spicy taste of these plants results from glycosinolates, particularly abundant in this family.
Brassicaceae are distinguished well from other plants by their flowers with four petals arranged in a cross and the six stamens (two shorter). The family has c. 4,000 species found throughout the world. In Portugal there are c. 107 species.
It is very important to finalising databasing this family!
