[VOL. 10 



obovoid, appearing obscurely apiculate because of. the position of the hairs at 

 the tip, but actually rounded at the apex, nearly closed, the tiny apical aperture 

 with 4 or 5 dark marginal gland-like teeth ; calyx glabrous within, apparently 

 opening by irregular longitudinal breaks; hypanthium prolonged 1.5 mm beyond 

 the summit of the ovary, glabrous within except the hairy staminal ring; stamens 

 150 or more, the anthers 0.4 mm long; petals 4 or 5, fleshy, spatulate or sub- 

 rotund, silky on the outer surface, 1-2.5 mm long, 1.5-2 mm wide ; ovary bilocu- 

 lar, with two ascending ovules in each locule. 



VENEZUELA: Amazonas: Cerro de la Neblina, Rio Yatua, forests on middle slopes, 

 elevation 650-700 m, Dec 23, 1953, Maguire et al. 36820 (MICH, type). 



21. Marlierea cana McVaugh, sp. no v. 



Arbor, vel frutex 2 m altus, appresse pubescens vel canescens, paniculis 

 ramulisque novellis pilis incanis, usque ad 0.5 mm longis obsitis; ramulis exalatis; 

 foliis 6-9 cm. longis, obtusis; nervo medio supra convexo; venis non impressis; 

 petiolis 3-7 mm longis; paniculis 5-9 cm longis, 20-30-floris, elongatis (non ut in 

 Marlierea geminatis), e nodis mediis (verosimiliter bracteatis) rami foliacei 

 oriundis; bracteis deciduis; alabastris clausis, 3.5-4.5 mm longis; calyce ad 

 anthesin circumscisso, hypanthii margine revoluto, lobos inaequales parvos 

 gerenti. 



Tree, or shrub 2 m high, the young growth and inflorescence (especially the 

 hypanthium) appressed-pubescent or canescent with grayish-white hairs up to 

 0.5 mm long; leaves coriaceous, elliptic or ovate, (2.8-) 3.5-6 cm wide, 6-9 cm 

 long, 1.3-2.2 times as long as wide, blunt-pointed, obtuse and emarginate, or 

 rounded at the tip, obtuse to rounded or subtruncate at the base, the margins 

 abruptly decurrent on the petiole 1.5-2 mm thick, 3-7 mm long; midvein convex 

 or flattened above, narrowly channeled near the base, prominently convex be- 

 neath ; lateral veins 10-15 pairs, inconspicuous, raised a little on both sides when 

 dry ; marginal vein about equaling the laterals and slightly arched between them, 

 1-2 mm from the margin ; blades smooth and lustrous above, paler beneath, finely 

 dark-dotted on both sides when young, at maturity obscurely impressed-punctate 

 above and very finely dotted beneath; inflorescence a myrcioid panicle, 5-9 cm 

 long, 3 times compound, 20- to 30-flowered, borne at one of the middle (probably 

 bracteate) nodes of a leafy shoot; peduncle 2.5-4.5 cm long, compressed, 2-2.5 

 mm wide just below the first node, the basal branches of the panicle 2-4 cm 

 long, the flowers clustered near the tips of the branches ; buds closed, 3.5-4.5 mm 

 long, obovoid, bluntly and shortly apiculate ; calyx calyptrate, with small irregu- 

 lar accessary lobes persistent on the margin of the hypanthium, the calyptra 

 silky within ; hypanthium after dehiscence campanulate, or attenuate at the base, 

 2.5-3 mm long, the orifice about 3 mm in diameter, the thin margins abruptly 

 revolute, with small irregular lobes, at least the base of the tube persistently 

 canescent; style 4-6 mm long; stamens about 125, 4.5 mm long, the anthers 0.2- 

 0.3 mm long; petals 1 or 2, oblong to suborbicular, hirsute on the outer surface, 

 somewhat adherent to the calyptra at the base, 1-2 mm wide, 1.5-2 mm long; 

 ovary bilocular, with 2 ascending ovules in each locule ; immature fruit globose to 

 oblate, "turning red brown" (Cowan and Wurdack), 4-6 mm in diameter. 



VENEZUELA: Amazonas: Cerro Duida, Rio Cunucunuma, forested ridge west of Cano 

 Culebra, elevation 1700-1800 m, Nov 22, 1950, Maguire et al. 29653 (MICH, type) ; Bio Ven- 

 tiiari, Serrania Paru, Rio Paru, Cano Asisa, elevation 2000 m., Feb 10, 1951, Cowan 4" Wur- 

 dack 31386 (MICH), Feb 4, 1951, 31227 (NY). 



The generic position of this species may be questioned; the calyx is definitely 

 calyptrate as in Calyptranthes, but the calyptra breaks off somewhat irregularly
