Iram Mujahid
Abstract
The living collection of plants in botanic gardens and academic institutions play an important role in scientific research, education and conservation. The University of the Punjab (PU) is one of the oldest and largest seat of higher education learning in Pakistan with its two main academic campuses located in the city of Lahore. Besides several on-campus plantations, PU has a dedicated botanical garden established in 1963.We documented all the woody plant species planted in the botanical garden and on both the campuses. Extensive surveys of all the blocks on both campuses were carried out during 2014-15. As a result, a total of 220 woody plant species belonging to 55 plant families and 157 genera are being reported here.The major plant families in terms of species contribution were Fabaceae (33), Moraceae (19), Myrtaceae (13), Rutaceae (12) and Euphorbiaceae (12). The PU botanical garden represents 87% of total tree collection of both the campuses with 50 trees present only in the botanical garden and another 28 only found within the campus area. The tree flora of PU is a representative of the whole Lahore district and about half of the country. We report eight trees species (namely Pleiogynium timoriense, Pittosporum angustifolium, Handroanthus impetiginosus, Discladium obtusatum, Sapindus saponaria, Syzygium heyneanum, Tabebuia aurea and Anogeissus acuminata) as new records to the Flora of Pakistan.
