The research aims to explain the plant composition and morphology profile of four road shade plant species in Malang City. The observed road shade plants consist of Handroanthus chrysotrichus, Bauhinia purpurea, Spathodea campanulata and Erythrina fusca. The study was conducted in May to June 2022. Observations included the number of plants, plant density, stem circumference, plant height, canopy covering an area, and plant canopy shape parameters. The results showed that generally, the composition of four road shade plants in Malang City was 49.24 percent S. campanulata, 21.02 percent B. purpurea, 15.63 percent E. fusca, and 14.11 percent H. chrysotrichus. The H. chrysotrichus had a square-shaped canopy, B. purpurea had a dome-shaped canopy, S. campanulata had a rounded-shape canopy, and E. fusca had an irregular-shape canopy. Most of the densities of H. chrysotrichus, B. purpurea, and S. campanulata were 3-6 (trees/500 m), and the E. fusca was less than 3 (trees/500 m). Most H. chrysotrichus and B. purpurea plants had 50-100 cm, S. campanulata 100-150 cm, and E. fusca less than 50 cm stem circumference. Most of the plants of H. chrysotrichus, B. purpurea, and E. fusca had 4-7 m, and S. campanulata had 7-10 m plant height. All shade plants had a 3-12 m2 canopy covering the area.
