After considerable study of this plant I am inclined to place it in the 
general alliance with Glyceria R. Brown, but am not entirely satisfied 
that this is its proper disposition. In its facies and in details it is quite 
different from Glyceria. Its striking distinguishing characters are its 1- 
to 3-flowered spikelets, its distant glumes, its flowering glumes slightly 
inflated and longitudinally sulcate at the base, and its produced rachilla 
that is tipped with a very greatly reduced sterile glume, so reduced usually 
as to appear like a mere enlargement of the tip of the rachilla. 
The genus is dedicated to Maximo Ramos, who for many years has 
been employed by the Bureau of Science as a botanical collector, and whose 
field work has yielded material on which the descriptions of several hundred 
new species have been based.

Alte scandens, glabra ; foliis coriaceis, in siccitate pallidis, an- 
guste lanceolatis, usque ad 45 cm longis et 6 cm latis, tenuiter 
longissime caudato-acuminatis, basi obtusis, leviter inaequilate- 
ralibus, nervis collectivis utrinque 2 vel 3, distinctis ; petiolo cir- 
citer 15 cm longo, in siccitate tubuloso, usque ad geniculis vagi- 
nato ; pedunculis 2 vel 3, 4 ad 7 cm longis ; spathis oblongo-ovatis, 
coriaceis, usque ad 15 cm longis et 5.5 cm latis, caudato-acumi- 
natis; spadicis sessilibus, cylindraceis, 4 ad 5 cm longis, circiter 
1 cm diametro. 
A stout, climbing vine, rooting copiously at the nodes, the 
stems about 1 cm in diameter, the nodes not prominent, the 
internodes about 2 cm long. Leaves coriaceous, pale when dry, 
narrowly lanceolate, slightly inequilateral, 30 to 45 cm long, 4 
to 6 cm wide, base somewhat narrowed, obtuse, apex long and 
slenderly caudate-acuminate, the acumen up to 3 cm in length, 
the midrib very prominent, the longitudinal collective nerves 2 
or 3 on each side of the midrib, slender, distinct, the third one 
when present submarginal; petiole about 15 cm long, cylindric 
when dry, narrowly winged throughout its length, at most 8 mm 
in diameter. Peduncles 2 or 3, each subtended by a narrowly lan- 
ceolate, long-acuminate, somewhat sheathing bract up to 11 cm 
in length, the peduncles 4 to 5 cm long. Spathes oblong-ovate, 
coriaceous, up to 15 cm long and 5.5 cm wide, long and slenderly 
caudate-acuminate. Spadices sessile, cylindric, obtuse, 4 to 5

A most striking species, clearly in the alliance with Pothos rumphii 
Schott, but with entirely different leaves, much broader spathes, and shorter, 
sessile spadices.
