Well developed tap root system
small leaves with thick epidermis

Forklaring
Desert plants have adapted to the hot, dry conditions if the desert by developing specialised features such as; small or absent leaves, narrow, waxy, hairy leaves, deep roots to access deep water in the soil.
Broad leaves would lead to excessive water loss through Transpiration, making it difficult for desert plants to survive. Hence, broad leaves is not adaptation of plants in desert environment.
