CAPPARIDACEAE FAMILY PDF

Herbs, erect or scandent shrubs, rarely small trees, often glandular hairy. Leaves alternate or rarely opposite, simple or digitately rarely 1, 2 or 9- -foliolate; leaflets usually entire; stipules , often spiny, persistent or caducous. Inflorescence terminal or axillary, often corymbose, sometimes solitary or fascicled. Flowers hermaphrodite rarely dioecious , regular, sometimes with unequal sepals or petals, complete or rarely petals wanting, pedicellate.

Capparidaceae

The Capparaceae or Capparidaceae , commonly known as the caper family, are a family of plants in the order Brassicales. As currently circumscribed, the family contains 33 genera and about species. The largest genera are Capparis about species , Maerua about species , Boscia 37 species and Cadaba 30 species. The Capparaceae have long been considered closely related to and have often been included in the Brassicaceae , the mustard family APG, , in part because both groups produce glucosinolate mustard oil compounds. Subsequent molecular studies [3] support Capparaceae sensu stricto as paraphyletic with respect to the Brassicaceae. However Cleome and several related genera are more closely related to members of the Brassicaceae than to the other Capparaceae.

The Families of Angiosperms

Capparidaceae Capparaceae ; order Capparidales A family of dicotyledonous Dicotyledoneae plants most of which are shrubs and small trees. The leaves are alternate, simple or compound , with stipules which are sometimes spiny. The flowers are usually borne in racemes , and have 4 petals , 2 pairs of sepals , 4—6 or more stamens , and a superior ovary of 2 carpels. The fruit is a berry , nut or drupe.
