Cycas, the single genus of the family Cycadaceae, consists of about 100 species, chiefly Indo-Chinese (40) and Australian (27). Cycads vary in size from trunks only a few centimeters to several meters tall. Slow in growth, cycads live long, some species known to last about 1,000 years.

Cycas rumphii is commonly confused with Cycas revoluta, but pitogo is a much larger plant, with larger leaves and smooth and glabrous ovules. Trunk is stout and woody, growing to a height of 12 meters, 20 to 50 centimeters in diameter, with a round and symmetrical crown of large, hard, stiff, evergreen leaves. Leaves are 1.5 to 2.5 meters long, crowded at the apex of the trunk, leaflets are 20 to 30 centimeters long, about 1 centimeter wide, smooth and shining, falcate, 45 to 90 on each side of the midrib. Male cones are terminal, elongated-cylindric or ovoid-cylindric. Leaves are numerous, about 30 centimeters long and densely rusty-tomentose. Fruit is smooth, ovoid to ellipsoid, 3 to 5 centimeters long.

- Seeds also reportedly eaten in India, the Andaman, in the Malay Peninsula, and the Dutch Indies.
- In India, a kind of sago is prepared from the starch stored in the trunk.
