Nasir, Yasin J. (1983) A REVISION OF THE FAMILY PRIMULACEAE FROM PAKISTAN. PhD thesis, University of Karachi, Karachi.



In the present study the family Primulaceae, represented by sixty one taxa, is revised from Pakistan and Kashmir. A synthetic approach has been used utilizing the information available from various fields including the macromorphological characters, seed and pollen morphology. Eleven new taxa are described for the first time. These include Androsace hazarica Y. Nasir, A. ojhorensis Y. Nasir, A. lowariensis, Y. Nasir, A. baltistanica Y. Nasir, Y. russellii Y. Nasir, A. staintonii Y. Nasir and primula denticuloides Y. Nasir; the 3 new subspecies are Y. Nasir, A. aizoon ssp. Androsace himalaica, ssp. kurramensis brirensis Y. Nasir and Cortusa matthioli ssp. hazarica Y. Nasir. Androsace robusta var. gracilis Y. Nasir is newly described from Ladak. The following taxa are given new status: Androsace rotundifolia ssp. glandulosa (Hook. f.) Y. Nasir, A. thomsonii (Watt) Y. Nasir,A. villosissima (Knuth) Y. Nasir and Lysimachia japonica ssp. Papuana (5. Moore) Y. Nasir. A combination and status novum has been given to Androsace robusta ssp. jacquemontii (Duby ex DC.) Y. Nasir, Y.harrissii ssp. crassifolia (Wendelbo) Y. Nasir and one new name given i.e. A. alii Y. Nasir. primula heydei Watt has been placed as a synonym of P. minutissima Jacq. The classification of the genus Androsace is revised and includes 2 new subsections i.e. subsect. Himalaicae and subsect. Harrissianae. The series Mucronifoliae Handel-Mazzetti given sub-sectional rank. In the genus Primula the subsect. Inayatii and subsect sibirica(classification after subsect. Inayatii and subsect.Smith and Fletcher, 1942) are accorded sectional rank. The scanning of both the pollen and the seed for most of the Himalayan taxa studied, has been done for the first time and the characters employed in this respect have proved to be useful in assessing relationships and redefining groups. Descriptions accompanied by for all the taxa concerned, along their geographical distribution. detailed drawings are given with notes and maps showing Endemism is briefly discussed.
