The genus Rhododendron is a large group of woody plants that includes about 1,000 species and countless cultivars. The name Rhododendron is derived from the Greek words "rhodon" meaning rose and "dendron" meaning tree, reflecting the showy and colorful flowers that these plants produce. The specific epithet "makinoi" honors the plant's discoverer, Tomitaro Makino. Morphology Rhododendron makinoi is a deciduous or evergreen shrub that can grow up to 3 meters tall and wide. Its leaves are elliptic to oblong in shape, 5-15 cm long, and 2-5 cm wide. The upper surface of the leaves is dark green, while the lower surface is pale green with a few hairs. The leaves are arranged alternately on the stem and have a prominent midrib and veins. The flowers of Rhododendron makinoi are bell-shaped, 2-3 cm long, and are usually produced in clusters of 3-10 at the ends of the branches. The flowers come in a range of colors, including pink, purple, red, and white, and have spots or blotches on the inside of the corolla. The stamens are shorter than the corolla and are usually white or yellow.
