A Numerical Taxonomy of the Genus Rosularia (Dc.) Stapf from Pakistan and Kashmir
Pak. J. Bot., 44(1): 349-354, 2012. A NUMERICAL TAXONOMY OF THE GENUS ROSULARIA (DC.) STAPF FROM PAKISTAN AND KASHMIR GHULAM RASOOL SARWAR* AND MUHAMMAD QAISER Centre for Plant Conservation, University of Karachi, Karachi-75270, Pakistan Federal Urdu University of Arts, Science and Technology, Gulshan-e-Iqbal, Karachi, Pakistan Abstract Numerical analysis of the taxa belonging to the genus Rosularia (DC.) Stapf was carried out to find out their phenetic relationship. Data from different disciplines viz. general, pollen and seed morphology, chemistry and distribution pattern were used. As a result of cluster analysis two distinct groups are formed. Out of which one group consists of R. sedoides (Decne.) H. Ohba and R. alpestris A. Boriss. while other group comprises R. adenotricha (Wall. ex Edgew.) Jansson ssp. adenotricha , R. adenotricha ssp. chitralica, G.R. Sarwar, R. rosulata (Edgew.) H. Ohba and R. viguieri (Raym.-Hamet ex Frod.) G.R. Sarwar. Distribution maps of all the taxa, along with key to the taxa are also presented. Introduction studied the genus Rosularia and indicated that the genus is polyphyletic. Mayuzumi & Ohba (2004) analyzed the Rosularia is a small genus composed of 28 species, relationships within the genus Rosularia. According to distributed in arid or semiarid regions ranging from N. different workers Rosularia is polyphyletic. Africa to C. Asia through E. Mediterranean (Mabberley, There are no reports on numerical studies of 2008). Some of the taxa of Rosularia are in general Crassulaceae except the genus Sedum from Pakistan cultivation and several have great appeal due to their (Sarwar & Qaiser, 2011). The primary aim of this study is extraordinarily regular rosettes on the leaf colouring in to analyze diagnostic value of morphological characters in various seasons. -

It is being submitted for the Degree of Doctor of Philosophy in the University of the Witwatersrand, Johannesburg. It has not been submitted before for any degree or any other examination in any other University. ______________________ ______ day of ______________________ 20_____ ii ABSTRACT Introduced plants will lose interactions with natural enemies, mutualists and competitors from their native ranges, and possibly gain interactions with new species, under new abiotic conditions in their new environment. The use of biocontrol agents is based on the premise that introduced species are liberated from their natural enemies, although in some cases introduced species may not become invasive because they acquire novel natural enemies. In this study I consider the potential for the biocontrol of Bryophyllum delagoense, a Madagascan endemic, and hypothesize as to why this plant is invasive in Australia and not in South Africa. Of the 33 species of insects collected on B. delagoense in Madagascar, three species, Osphilia tenuipes, Eurytoma bryophylli, and Rhembastus sp. showed potential as biocontrol agents in Australia. -

CPC Best Plant Conservation Practices to Support Species Survival in the Wild
CPC Best Plant Conservation Practices to Support Species Survival in the Wild Lilium occidentale ii CPC Best Plant Conservation Practices to Support Species Survival in the Wild CENTER FOR PLANT CONSERVATION iii About the Center for Plant Conservation CPC’s mission is to ensure stewardship of imperiled native plants. To do this, we implement the following tested and effective strategy: We advance science-based best practices in plant conservation through our network of conservation partners known as Participating Institutions. Our network actively applies these practices to save plants from extinction here in North America as part of the CPC National Collec- tion of Endangered Plants. We share best practices with conservationists all over the world and advocate for plants and their value to humankind.

Weeds of the future? Threats to Australia’s grazing industries by garden plants Abstract This report identifies 281 introduced garden plants and 800 lower priority species that present a significant risk to Australia’s grazing industries should they naturalise. Of the 281 species: • Nearly all have been recorded overseas as agricultural or environmental weeds (or both); • More than one tenth (11%) have been recorded as noxious weeds overseas; • At least one third (33%) are toxic and may harm or even kill livestock; • Almost all have been commercially available in Australia in the last 20 years; • Over two thirds (70%) were still available from Australian nurseries in 2004; • Over two thirds (72%) are not currently recognised as weeds under either State or Commonwealth legislation. -
Some Major Families and Genera of Succulent Plants
SOME MAJOR FAMILIES AND GENERA OF SUCCULENT PLANTS Including Natural Distribution, Growth Form, and Popularity as Container Plants Daniel L. Mahr There are 50-60 plant families that contain at least one species of succulent plant. By far the largest families are the Cactaceae (cactus family) and Aizoaceae (also known as the Mesembryanthemaceae, the ice plant family), each of which contains about 2000 species; together they total about 40% of all succulent plants. In addition to these two families there are 6-8 more that are commonly grown by home gardeners and succulent plant enthusiasts. The following list is in alphabetic order. The most popular genera for container culture are indicated by bold type. Taxonomic groupings are changed occasionally as new research information becomes available. But old names that have been in common usage are not easily cast aside. Significant name changes noted in parentheses ( ) are listed at the end of the table.
