Description:Latin Diagnosis - A d Cymosas Trel.; nullo aho affinitatem praebet nisi P. dichotomo (Bert.) Kr. & Urb., a quo abhorret cataphyllorum pari unico tubuloso, foliis crassioribus absque nervis fructibusque aurantiacis. Fruticulus dioicus, plus minusve castaneus, ramis dichotomis cymosisque, dichotomiis spicis gerentibus hand raro, teretibus; internodiis 3-7 cm longis. Vagina cataphyllaris 1 ad omnes internodiorum bases, tubulosa, vulgo circa 3 mm alta, supremae fere integrae infimaeque plus minusve bifidae, omnes margine rotundatae absque denticuhs. Foha in universum ovata, saepe oblonga vel oblongoovata, basi breviter cuneata, apicem versus magis attenuata, extremo apice acuta, frequenter obhqua aut falcata, crasse rigideque coriacea, utrinque nervis destituta et ad lentem rugosissima et nitidula, margine incrassato scrobiculato ut morsicatus esset cincta, 6-9 cm longa, 2-4 cm lata; petiolus parum a limbo distinctus, circiter 5 mm longus. Spicae terminales ad dichotomias axillaresque, 1-2-nae, 3-articulatae, graciles, rubrae, floriferae 2-3 cm longae, fructiferae 5-6 cm longae; pedunculus 3-6 mm longitudinem metitur, 1-2 vaginis sterilibus suffultus; articuli fere cyhndrici, floriferi 5-6 mm, fructiferi ad 2 cm usque longi, 10-24-flori, floribus 4-seriatis. Fructus late ovoideus, 4-5 mm longus, epicarpio fusco-rubro perrugoso interdum videtur granuloso obtectus, perigonio prorsus clauso coronatus.

Discussion:Type. Frequent on shrubs, scrub, and low forest (8-10 m) on shoulder of east flank, above Thompson Camp, 1418-1525 m. Mount Ayanganna, Upper Mazaruni River Basin, Guyana, 10 Aug 1960, S. S. Tillett, C. L. Tillett & R. Boyan 45088 (holotype RB, isotype NY). Paratype. Edge of forest, savanna near G. S. Camp 1, Ayanganna Plateau, 747 m , Guyana, 22 Jul 1960, 44914. The species is noteworthy by its leaf margin which seems to have been minutely nibbled. From its nearest relative, P. dichotomum, it is distinguished by its tubulose cataphylls as well as its thicker, nerveless leaves.
