The oldest leaf forms the outermost layer of the crownshaft . Eventually the lowest palm frond dies back, the outer layer of the crownshaft splits, the leaf unwraps and pulls away from the trunk exposing the new crownshaft surface.

With its slightly grouped pinnae, and glabrous inflorescences branched to 2 orders, this species is allied to D . oreophila and D . tsaratananensis, from which it is easily distinguishable by its larger crownshaft, longer leaves with larger pinnae, the much longer inflorescences, and the larger fruit.

On flowering, they produce up to six inflorescences which ring the trunk below the crownshaft, branched to one order, with white to yellow flowers, which are male and female; both pistillate and staminate flowers have three sepals and three petals, the former being smaller than the latter.

The authors describe " P . cattienensis ", as differing from all previously described species of " Pinanga " from Viet Nam, by its leaf sheaths which do not form expanded / extended bases of the leaves to form a crown ( " crownshaft " ) and inflorescences which are not situated below the leaves.
