Cycas pectinata was the fourth species of Cycas to be named; it was described in 1826 by Scottish surgeon and botanist Francis Buchanan-Hamilton from Kamrup, Assam in northeast India. The species is one of the most widespread cycads. It is found in the northeastern part of India, Nepal, Bhutan, northern Burma, southern China (Yunnan), Bangladesh, Burma, Malaysia, Cambodia, northern Thailand, Laos, and Vietnam. Cycas pectinata usually grow at elevation 300 m to 1200 m and in difficult terrains. In China, it grows in dry, open thickets in limestone mountains, red soil in sparse monsoon forests. Cycas pectinata grows up to 40 feet (12 m) tall and has very large, ovoid male cones. The tallest Cycas pectinata is a female plant in North Kamrup, Assam which measures 52.8 feet (16.1 m). The tree is the world's tallest Cycas plant. In Northeast India, the species is under severe threat due to clearing of forest and over collection of male cones for preparation of traditional medicines.
