Asphodelaceae
Asphodelaceae Juss. comprises approximately 40 genera and 900–950 species, distributed mainly in Africa, Europe, Asia, and Australia. Modern molecular phylogenetic studies have broadened the family to include the formerly recognized families Aloaceae, Asphodelaceae sensu stricto, and Hemerocallidaceae, which are now treated as the subfamilies Alooideae, Asphodeloideae, and Hemerocallidoideae, respectively. Members are well known for their succulent leaves, ornamental value, and medicinal importance, particularly the genus Aloe.

Distribution
Asphodelaceae is distributed throughout the Old World, with its greatest diversity in southern Africa, particularly the Cape Floristic Region, which is the principal centre of evolution for Aloe, Haworthia, Bulbine, and allied genera. Additional representatives occur across the Mediterranean region, the Middle East, Central Asia, Australia, and parts of tropical Asia. Members inhabit deserts, rocky slopes, grasslands, Mediterranean shrublands, savannas, and open woodlands, where many species are adapted to drought through succulent leaves and specialized water-storage tissues. In Pakistan, Asphodelaceae is represented primarily by native species of Asphodelus and Eremurus, while several species of Aloe are widely cultivated as ornamentals and medicinal plants. Native representatives occur, where they grow on dry rocky slopes, mountain grasslands, and open scrub vegetation. Cultivated Aloe vera is common throughout, and urban areas across Pakistan for medicinal and ornamental purposes.
