BOTANY OF THE GUAYANA HIGHLANDS PART V 



49 



Creek and Augustus Creek, hill no. 1, Tafelberg, Suriname, 570 m, 13 Aug 1944, 

 Bassett Maguire 24726 (holotype fl., fr. NY ; f r. A) . 



Distribution. A tree to 15 m with large, extremely coriaceous, elliptic leaves, 

 the pale brownish under contrasting with the olive-green upper surface, known 

 only from the type locality. 



The nearest alliance seemingly is the new species A. castanea, another equally 

 arresting species from Tafelberg, Suriname. The two are easily distinguished, 

 however, by the dense, conspicuous reticulations of the leaves of the latter species 

 which is smaller in every dimension. Examination of the flower structure shows 

 no near relationship. 



The type of this species also was reported (Allen, 1. c.) as Ocoteaf on the 

 fruiting material alone at the Arnold Arboretum.

 scentibus mox cinereo-glabrescentibus subteretibus. Folia alternata suboppositave, 

 petiolis robustis atro-brunnescentibus glabrescentibus canaliculars, 10-12 mm 

 longis et 3-4 mm latis, laminis supra glabris subtus glabrescentibus coriaceis, 

 supra viridibus subtus opacis, ellipticis, (4-) 6-13 cm longis et (2-) 2.8-5.3 cm 

 latis, margine recurvatis, ad basim acutis rotundatisve, ad apicem acutis vel 

 subacuminatis, raro obtusis vel emarginatis, penninerviis, costa brunnea, supra 

 leviter subtus conspicue elevata, nervis ±8-paribus utrinque ± inconspicuis, ad 

 angulo 50-45° divergentibus, rete venularum obscure minuteque areolato. In- 

 fiorescentia terminalia robusta, ut videtur patenti-paniculata, ad 3.5-5 cm longa, 

 utrinque dense adpresseque cinnamomeo-pubescens, pauciflora, subsessilis. Flores 

 4-5 mm longi, pedicello 1.5-2 mm longo aliquantum robusto ; perianthio campa- 

 nulato, lobis satis crassis late ovatis, ad 1.5 mm longis, tubo lobis aequali vel 

 longiore ; staminibus fertilibus pubescentibus, ser I & II ad 0.8 mm longis, 

 antheris subrotundatis introrsis, connectivo anguste obtuso producto, filamentis 

 crassis quam antheris brevioribus, ser III quam I & II leviter brevioribus 

 biglandulosis, glandulis sessilibus, antheris ± apicali-extrorsis ; gynoecio 1.8-2 

 mm longo, ovario subrotundato vel ovoideo pubescenti, ad apicem attenuato quam 

 stylo robusto breviore, stigmate minute lobato. Infructescentia brevis et de- 

 pauperata, glabrescens. Fructus viridis, ellipsoideus, ad 1.8 X 1.3 cm, cupula 

 rubra, fide coll., cyathiformi tenui verruculosa, ad 12 mm longa, ad 15 mm diam., 

 et ad 4r-5 mm alt., stipite ad 5 mm longo, pedicello incrassato glabrescenti, ad 

 3 mm longo. 



Type. Small tree 2 m, woodland in Cano Grande, Cerro Sipapo (Paraque), 

 Amazonas, Venezuela, 1150 m, 20 Jan 1949, Bassett Maguire & Louis Politi 28476 

 (holotype, fl. NY). 



Distribution. Known only from the Cerro Sipapo region where it occurs along 

 streams or near mountain summits at 1500-1800 m. VENEZUELA. Amazonas : 

 near summit of West Mountain, Cerro Sipapo (Paraque), Maguire & Politi 2812 J 

 (fl., fr. NY), infrequent at stream-side, upper Cano Negro, 28241 (fr. NY). 



The smooth, extremely leatherly leaves with robust petioles, olive-green above 

 and brownish beneath, the venation obscure except for the broad midrib, plane 

 above and slightly elevated beneath, mark this as distinct vegetatively. The 

 cinnamon-colored pubescence clothing the stout, subterminal inflorescence also 

 is a distinguishing characteristic.
