Corypha lecomtei (common name Cay la buong) is a species of plant in the family Arecaceae.

[citation needed] Although known locally for centuries, it was formally described in 1916 by the botanist Odoardo Beccari.

[1] This palm species has a trunk 3.5–4 metres (11–13 ft) high and up to a full meter (40 inches) thick, and the palmate leaves are even larger, with petioles up to 8.8 metres (29 ft) long[2](exceeded only by Musa ingens and Lodoicea) and canaliculated (round in cross-section with a deep groove on the upper surface).

The palmate leaf blade, or lamela is 3.5–4 metres (11–13 ft) in length.

[4] The plant flowers and fruits only once (monocarpy), at between 15 and 30 years of age, and then dies.
