Tamaricaceae includes 4 genera and nearly 120 species, chiefly distributed in temperate and subtropical regions of the old World. It is represented by 36 taxa belonging to all the 4 genera in Pakistan.

The family has considera1le economic importance. Most of the plants are halophytes and good indicators of water logging and salinity. The wood of Tamarix aphylla (L.) Karst. is used in North Arabia and N. Africa for making house raftors. In N. Africa, Arabia and Iran, galls called Takut or Teggant, derived from this species are used for obtaining tannin, used for fine qualities of goat and sheep skins which take up purplish or pink colour (Hutchinson, 1967). Some Tamarix species have high content of tannin e.g. T.ramosisson Ledeb. has 1.54% tannin (Kurdiashev, 1932). Sukhowkov (1924) obtained 12% tannin in young branches of 2 species of Tamarix. Tamarix manna, a sweet excretion of insects, living on Tamarix (Bodenheimer,1929), is used in medicine s in India and Arabia (Hutchinson, 1967). The twigs of T.dioica Roxb. ex Roth are used in local medicines for curing ring worms, gonorrhoea etc.(Said, 1969). Some of the species of Tamarix and myricaria are cultivated as ornamental plants (Bailey, 1950; Lawrence, 1951) and a few are used for afforestation (Herriot,l942 and Hawkins,195B). Tamarix species are highly adabtable on sandy soils, especially on the sea shore and are extensively employed in these situations as shelter belt plants.

The presence of minute and intricate nature of character differences between most of the taxa has offered annoying difficulties to botanists when. trying to delimit the species infra specific taxa. This has resulted resulted into an a1arming accumulation to names. It was felt that in addition to classical taxonomic methods, a synthetic approach is likely to be useful in such a group. Hence a biosystematic study of Tamaricaceae from Pakistan has been carried out. Data obtained from the different fields such as chemotaxonomy, palynology, seed morphology, embryology, cytology and general morphology was taken into account in order to reach the taxonomic conclusions.

The main thesis is divided into 5 parts, dealing with seed morphology, chemotaxonomy, palynology, cytology and embryology and systematic treatment.
