It differs from Blakea penduliflora in having smaller, elliptic-lanceolate (vs.
10-15 mm long), sepals lanceolate to elliptic-lanceolate
6 mm wide, inner bracts elliptic-lanceolate
to elliptic, 4.
Sterile laminae are lanceolate to elliptic-lanceolate, pinnate.
Sterile laminae lanceolate to elliptic-lanceolate, up to 130-140 cm, pinnate, herbaceous in texture, base cuneate, attenuate, having aphlebiae along the stipe, apex acute or largely prolonged in a radicant axis, both types of apices appear in different fronds of the same plant.
