POLLEN FLORA OF PAKISTAN-XXXVII. TAMARICACEAE MOHAMMAD QAISER AND ANJUM PERVEEN Abstract: Pollen morphology of 35 taxa of the family Tamaricaceae from Pakistan has been examined by light and scanning electron microscope. Pollen grains usually radially symmetrical, isopolar prolate-subprolate, rarely prolate-spheroidal, colpate Sexine thinner or thicker than nexine. Tectum reticulate to reticulate – rugulate or foveolate or areolate. On the basis of tectum and relative thickness of sexine and nexine three distinct pollen types are recognized viz., Myricaria squamosa - type, Reaumuria alternifolia -- type and Tamarix aphylla – type. Pollen of the genus Tamarix are divided two groups viz., columellae present inside the luminae and luminae without columellae. Playnological data has been useful at generic and specific level.
