The living collection of plants in botanical 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 oncampus
plantations, PU has a dedicated botanical garden established in
1963. We documented all the tree species of the botanical garden and
both of the campuses through extensive surveys during 2014-15. A total
of 220 woody plant species belonging to 157 genera of 55 plant families
were being reported. The major plant families in terms of species
contribution were Fabaceae (34), Moraceae (19), Myrtaceae (14),
Rutaceae (12) and Euphorbiaceae (11). The PU botanical garden
represents 87% of the total tree collection of both the campuses. The
tree flora of PU is a representative of the whole Lahore district and about
half of the country. Some rare and new tree species in Botanical garden
can be added into the flora of Pakistan.
