Geonoma stricta
subsp.
stricta
Geonoma maguirei
Bailey (1948: 102)
.
Type
:
SURINAME
. Coppename River headwaters,
24 July 1944
,
B. Maguire
24166
(
holotype
NY!).
Leaves
undivided, rarely pinnate; veins not raised or slightly raised and triangular in cross-section adaxially; pinnae 1(1–3) per side of rachis.
Inflorescences
unbranched, rarely branched; staminate flowers deciduous after anthesis, rarely persistent.
Distribution and habitat:—
From 2°20’–
7°10’N
and 52°50’–
58°50’W
in the northeastern Amazon region of
Suriname
and
French Guiana
, with an outlying specimen in
Guyana
, at 373(100–800) m elevation in lowland rainforest (
Fig. 38
).
Two specimens from
French Guiana
(
de Granville 4803, Le Prieur s. n.
) are unusual in having branched inflorescences with 2–3, stouter rachillae, and one has a pinnate leaf (the only one in this subspecies). They are recognized as the
neglecta
morphotype. One of these specimens (
Le Prieur s. n.
) has “
Geonoma neglecta
” written, in Trail’s hand-writing, on the label. This specimen was illustrated by
Wessels Boer (1968
, plate V) and determined by him as
G. bartlettii
.
However, the
type
of that name was destroyed and it is treated here as an excluded name. Two specimens from
Suriname
(
Sastre 1567, Wessels Boer 1558
), with larger leaves and inflorescences with persistent staminate flowers appear more like those of the
pycnostachys
morphotype of
subsp.
arundinacea
. These are recognized as the
large
morphotype.
