patule duplicato-ramosus, ramulis floriferis teretibus, vulgo 15-18 cm 
longis, rigidis, crassiusculis, 2-2.5 mm spissis. Fructus spherici, stig- 
matum residuis fere exacte apicalibus apiculato-mucronati, 7 mm dia- 
metro, perianthio concaviusculo minime pedicelliformi et braeteolis 
conspicuis, in cupulam brevem elevatis, suffulti. 
A tree about 6 m high. Leaves large; leaflets equidistant, about 5 cm 
apart on each side, ensiform, slightly falcate near the end, very gradually 
acuminate to a long subulate tip, papyraceous, shortly and slightly nar- 
rowed toward a not very acute base, subconcolorous on both surfaces, 
unicostate, accompanied on each side of the mid-costa by two rather 
prominent and distinct secondary nerves; the margins conspicuously 
thickened; at the base of the mid-costa on the upper surface is to be found 
a small but very distinct glandular tubercle; the few leaflets seen by 
me are apparently from the central part, these are 65 cm long, 3 cm 
broad. The spadix is diffusely twice branched, the primary branches 
being divided into 2 to 4 flowering branchlets; these are rigid, terete, 
usually 15 to 18 cm long, 2 to 2.5 mm thick, bearing the flowers and 
fruits spirally arranged. Fruit spherical, almost centrally mucronate- 
apiculate b} r the remains of the stigmas, 7 mm in diameter. Seed 5.5 
mm in diameter. Fruiting perianth very slightly concave. Floral bracts 
forming a distinct shallow cup for receiving the base of the perianth. 
The main axis of the spadix and branchlets very minutely scabrid.

Closely related to Eeterospathe elata, but distinguished by its branches and 
branchlets being shorter, thicker, and more rigid, more deeply scrobiculate, while 
the flower bracts form a distinct cup; by the fruit being less distinctly tuberculate 
on its surface, with the remains of the stigmas almost central ; and by the perianth 
being almost explanate and not subpedicelliform.
