Slender to moderate, clustering palm to 5.5 – 15 (– 21.6)m., withup to 3 adult stems, and up to 4 or more suckers at the base, crown spherical in outline.

Cyrtostachys glauca, is easily distinguished from all other species, by its spherical crown, glaucous leaf sheath and crownshaft, slender and elongate petioles, of more than 50 cm. long (– 100 cm.), papery leaflets, slender inflorescence, and rachilla with sparse superficial pits, and by the unique presence of trichotomosulcate pollen grains. This is a very peculiar species within Cyrtostachys, because of the nature of the pits along the rachilla. The pits are very shallow, or even lacking in a few specimens, and together with the tiny flowers (in bud), the species may be superficially confused, with Heterospathe or Rhopaloblaste. However, the generic characters such as presence of a crownshaft, connate petals, and stamens in staminate flowers; fruit and seed, morphology, still clearly indicate it as a species of Cyrtostachys.

Description

Slender to moderate, clustering palm to 5.5 – 15 (– 21.6) m, withup to about 3 adult stems and up to 4 or more suckers at base, crown spherical in outline. Stem 5 – 15 cm in diam., bright green and becoming grey in age, nodal scars conspicuous; internodes 3.5 – 7.5 cm long. Leaves 6 – 8 per crown, leaves spreading, 172 – 410 cm long (including petiole); sheath tubular, 66 – 130 cm long, 8 – 22 cm wide, forming a distinct crownshaft, 70 – 240 cm long, bright glaucous, sparsely and minutely lepidote with membranous brown scales; petiole green, elongate, 25 – 88 (– 100) cm long, 2 – 3 cm wide and 1 – 1.6 cm thick at the base, rounded and rather densely and minutely brown lepidote below, concave and similarly lepidote or puncticulate above; leaflets regularly arranged.

Cyrtostachys glauca, is easily distinguished from other species in its genus, by its spherical crown, glaucous leaf sheath and crownshaft, slender and elongate petioles, of more than 50 cm. long (– 100 cm.), papery leaflets, slender inflorescence, and rachilla with sparse superficial pits, and by the unique presence of trichotomosulcate pollen grains. This is a very peculiar species within Cyrtostachys, because of the nature of the pits along the rachilla. The pits are very shallow, or even lacking in a few specimens, and together with the tiny flowers (in bud), the species may be superficially confused, with Heterospathe or Rhopaloblaste. However, the generic characters such as presence of a crownshaft, connate petals, and stamens in staminate flowers; fruit and seed, morphology, still clearly indicate it as a species of Cyrtostachys.
