Geonoma stricta subsp. stricta

60a. Geonoma stricta subsp. stricta View in CoL

Geonoma maguirei Bailey (1948: 102) View in CoL . 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 View FIGURE 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.
