Geonoma pinnatifrons subsp. ramosissima (Burret) Henderson

49h. Geonoma pinnatifrons subsp. ramosissima (Burret) Henderson View in CoL , comb. & stat. nov.

Basionym: Geonoma ramosissima Burret (1930a: 249) View in CoL . Type: COLOMBIA. Antioquia: Cieneguetas, 27 July 1880, W. Kalbreyer 1892 ( holotype B, destroyed). Neotype (selected by Bernal et al. 1989): COLOMBIA. Antioquia: Mun. Frontino, Corregimiento de Murrí, road from Nutibara to La Blanquita, Río Cuevas, 950 m, 23 March 1982, R. Bernal & G. Galeano 306 ( neotype COL!, isoneotype NY!).

Leaf pinnae 15(12–17) per side of rachis. Inflorescences peduncular bracts inserted 1.3(1.0–1.5) cm above the prophyll; peduncles 19.3(16.5–22.0) cm long, 18.2(15.2–21.2) mm in diameter; rachillae 11.4(7.0–16.0) cm long, 1.6(1.1–2.3) mm in diameter; fruits 3.8(3.5–4.0) mm in diameter.

Distribution:— From 3°55’– 7°00’N and 75°54’– 77°37’W on the Pacific Coast and western slopes of the Western Cordillera in Colombia, at 427(0–1150) m elevation in lowland to montane rainforest ( Fig. 32 View FIGURE 32 ).

There is geographic discontinuity but too few specimens to test for differences, and too few to test for geographical variation. Three specimens ( Bernal 306, Betancur 2818, Forero 7370) from higher elevations on the western slopes of the Western Cordillera appear intermediate between this subspecies and G. interrupta subsp. magnifica , and may represent hybrids. They have the flower pits densely hairy internally distally only, as in G. interrupta .
