Adoxaceae Plant Family

Adoxaceae E. Mey DescriptionGeneral/Distribution: The family had been considered as monotypic, but quite recently Wu Cheng-Yi (in Acta Bot. Yunnanica 34:383-388, t. 1-2. 1981) has described two new Chinese genera-Tetradoxa C.Y. Wu and Sinadoxa C.Y. Wu.Acknowledgements:
The family's systematic position is doubtful. It was previously included in the Caprifoliaceae by Clarke (in Hook. f., Fl. Brit. Ind. 3:1.1880), from which it differs in the split stamens, semi-inferior ovary, 3-5-parted style and the general habit of the plant. Clarke (op. cit.) related the genus Adoxa to Chrysosplenium (Saxifragaceae). Willis (1973, ed. 8. Diet. Flow. Pl. & Ferns) is of the view that the family bears some resemblance to the Araliaceae, which it resembles in the inconspicuous flowers, semi-inferior ovary and the pendulous ovules. The present view is that family Adoxaceae is best placed between the families Caprifoliaceae and Valerianaceae.
Description
Small perennial, rhizomatous herbs. Leaves exstipulate; radical biternate, long petioled; cauline solitary or two; 3-foliolate. Flowers up to 5 in number. small, greenish, bisexual, in condensed cymose clusters. Calyx 2-3-lobed. Corolla 4-6-lobed. Stamens 4-5, epipetalous, alternating with the corolla lobes and apparently double their number, due to the deeply divided filaments; anthers monothecous. Carpels (2-)3-5, syncarpous. Ovary semi-inferior, with one pendulous ovule in each loculus. Fruit a drupe.

Family Aceraceae or Sapindaceae Discription

Aceraceae Juss. in Pakistan
The maple family (Aceraceae) and Sapindaceae recently b
een added to same Sapindaceae family.
General/Distribution: A bigeneric family of temperate North America, N.W. Africa, Europe, Asia and Indonesia. Acer is found in Pakistan. The other genus, Dipteronia, is endemic to central China.Description of Aceraceae
Trees or shrubs, usually deciduous, rarely evergreen. Leaves simple or compound, opposite, palmately lobed or unlobed-penninerved; petiole bases meeting but not perfoliate, usually exstipulate. Inflorescence corymbose, fasciculate or racemose, lateral or terminal on leafy or leafless shoots. Flowers actinomorphic, perfect or unisexual, rarely dioecious. Sepals and petals 4-5, rarely absent. Stamens 4, 6, 8, 10 or 12, inserted inside or outside the disc. Ovary bicarpellate, transversely compressed, bilocular, each locule biovulate; stigma usually bifurcate, rarely absent. Fruit a geminate samara; mericarps indehiscent.

Acanthaceae Discription

General/Distribution: A large family of nearly 250 genera and 2500 species, distributed mainly in the tropics and extending to Mediterranean, Australia and Southern U.S.A. In Pakistan it is represented by 18 genera and 60 specific and infra-specific taxa; of which 44 are native.

Description Perennial sometimes annual, suffrutescent, armed or unarmed herbs or shrubs, rarely climbers or small trees. Leaves exstipulate, usually simple, opposite-decussate, entire or undulate-dentate, rarely crenate-dentate or lobed, mostly with cystoliths on the upper surface, petiolate or sessile. Flowers commonly in dichasial cymes becoming monochasial, often in dense to lax spikes, racemes, panicles, sometimes fasciculate or verticilate, rarely solitary; sessile or pedicellate, bisexual, hypogynous, usually zygomorphic; bracts 1,2 or more, often coloured, frequently large, imbricate, persistent, rarely absent. Calyx usually gamosepalous, persistent, 4-5-lobed, lobes valvate or imbricate, sometimes spinescent or reduced to truncate or 10-15-dentate minute tube. Corolla gamopetalous, tube cylindrical or ventricose, the limb of 5, subequally spreading lobes or strongly 2-lipped; upper lip erect or suberect, entire or 2-fid rarely absent or fimbriate; the lower lip more spreading, 3-fid or 3-lobed, lobes imbricate or controrted. Stamens 4 and didynamous or 2, epipetalous, ascending below the upper lip; anthers dorsifixed, usually unequal in a stamen pair, dithecous or monothecous, thecae parallel, divergent or superposed, appendaged or bearded, longitudinally dehiscent; stamindodes 0-1-3. Ovary conical or oblong-cylindric, bicarpellate, syncarpous, superior, sessile or minutely stipitate, bilocular, placentation axile, rarely parietal, ovules 2-10 (-many) in each locule, in 1 or 2 vertical rows, rarely collateral, anatropous; style simple, filiform stigmas 1 or 2 minute. Fruits a bivalved, 2-loculed, clavate to elliptic-ovoid or oblong-cylindric, terete or compressed, usually ± stipitate capsule, elastically dehiscent from apex downwards, rarely drupaceous. Seeds mostly flattened and lenticular or discoid rarely globose or angular, borne on retinacula or papillae, testa smooth, rugose, echinate, tuberculate, glochidiate, appressed hairy or papillate, embryo with scanty or no endosperm.
