(ad torum) 3.8-4 mm longum subsericeo-strigosum ; calycis tubus 0.2 mm altus, 

 lobis interioribus 1.5 mm longis ovatis rotundatis ciliolatis, dentibus exterioribus 

 1.5 mm eminentibus lineari-lanceolatis setosis pilis p.p. glanduliferis. Petala 3.8- 

 4.2 X 2.6-2.7 mm oblongo-obovata apice rotundata glabra eciliata. Stamina 

 isomorphica glabra ; filamenta 2.3-2.8 mm longa ; antherarum thecae 2.8-3 mm 

 longae lanceolatae poro apicali, connective* basi non prolongato exappendiculato. 

 Stylus 7.5 X 0.25 mm; stigma truncatum ; ovarium 3-loculare 1/4-1 /3-inferum 

 apice in collum 0.3-0.4 mm altum circum stylum protractum collo cum setulis

Type. Leaves very viscid, flowers greenish white, occasional on lower east slope 

 of Cerro Moriche, Rio Ventuari, Terr. Amazonas, Venezuela, alt. 200-300 m, 

 16 Jan 1961, Bassett Maguire, R. 8. Cowan, & J. J. Wurdack 30971 (holotype 

 US 2342445). Paratype. VENEZUELA, Amazonas. Cerro Moriche: east slope, 

 alt, 300-800 m, Maguire, Cowan, & Wurdack 30864. 



In C. involucrata, the leaf blades are shortly plinerved, much less densely 

 pubescent, and acute to rounded (but not cordate) at the base; the floral bracts 

 are linear to lanceolate. In general aspect, especially in the inflorescence form, 

 C. morichensis is like C. capitata Benth. ; that eastern Guayana species is 

 eglandular, with predominantly 4-merous flowers, and with the ovary apex only 

 very shortly glandular-setulose. The inflorescences of C. morichensis are borne 

 one per branchlet from an upper leaf axil. 



Clidemia alternifolia Wurdack, sp. now

 ovarium 4-loculare omnino inferum apice sparse granuloso-furfuraceum et in 

 collum 0.35 mm altum circum stylum protractum. Bacca globosa teres; semina 

 1 X 0.3-0.6 mm pyramidata vel curvato-pyramidata minutissime irregulariterque 

 muriculata.
