POLLEN FLORA OF PAKISTAN – LXVIII
Pollen morphology 20 species of the family Alliaceae from Pakistan has been examined by light and scanning electron microscope. Pollen grains are usually bilateral, hetropolar mostly boat shaped, sexine thicker tor thinner than nexine. Tectal surface is mostly rugulate foveolate or subpsilate rarely reticulate. On the basis of apertural types 3 distinct pollen types are recognized, viz., Allium fedtschenkoanum –type, Allium grifthianum-type and Allium roylei-type.
Identification of monocot flora using pollen features through scanning electron microscopy
Pollen used to track structural and functional evolution in plants as well as to investigate the problems relative to plant classification. Pollen characters including ornamentation, shape, apertural pattern, pollen symmetry, colpus length, width, and margins used to detect the similarities and dissimilarities between genera and also species of the same genus. In this study pollen features of 20 monocot species belonging to 15 genera of the Amaryllidaceae, Asparagaceae, Iridaceae, Ixioliriaceae, Liliaceae, and Xanthorrhoeaceae were studied using scanning electron microscopy (SEM) and light microscopy (LM). In this study two species that is Zephyranthes citrina and Tulbaghia violacea were reported for the first time from Pakistan. Pollen grains were visualized with LM. Non‐acetolyzed and acetolyzed pollen were examined using SEM. A taxonomic key was developed to highlight the variation in pollen features in order to make their systematic application for correct species identification.
List of the described Coleoptera ofTasmania.
The Coleoptera of Tasmania have never been considered as 
a whole since the time of Erichson, and no list or 
catalogue of the species has ever been compiled. About 
10,000 species have now been recorded from Australia and 
Tasmania, of which scarcely 400 have been described from 
Tasmania. A very imperfect knowledge of what species 
are confined to the island exists, as species supposed only 
to occur there, are constantly being found in Victoria and 
New South Wales, and even sometimes in Western Australia 
and Queensland; on the other hand, Tasmanian 
collectors frequently obtain mainland species which have 
never been recorded from Tasmania. 
I have considered it advisable, therefore, to prepare a 
list of the species hitherto recorded from Tasmania, adding 
to the list such species as I have seen in Tasmanian collections, 
or have myself taken in Tasmania. In this list, 
the genera and families are placed as far as possible in the 
order in which they appear in Masters' "Catalogue of the 
Described Coleoptera of Australia;" the species are placed 
alphabetically. All known synonyms have been omitted.
