Benth. differ at least in the basally tapered hypanthia, more prominent external 

 calyx teeth, and pubescent ovaries. 



Maieta neblinensis Wurdack, sp. nov. 



A M. guianensi Aubl. et M. poeppigii Mart, ex Tr. differt hypanthiis distincte 

 10-alatis alis glandulifero-setosis inter alas glabris. 



Frutex 1-3 m in partibus juvenilibus furfuraceis tomento mox deciduo; rami 

 teretes petiolisque modice glanduloso-setosi pilis ca. 1.5 mm longis. Folia dis- 

 parilia membranacea supra sparse glanduloso-setulosa subtus in venis modice

 margines undulato-serrulata et glanduloso-ciliolata. Folia maiora: petioli 0.5-1.3 

 cm ; lamina basi vesiculif era ; vesica 2-3 cm longa oblonga modice longo-setulosa 

 pilis glanduliferis ; lamina expansa 15-28 X 6.5-12 cm oblongo-elliptica apice per

 axillis 1-4-faseiculatae 1-2 (-3) -florae ; pedunculus 0.4-2.5 cm longus compresso- 

 quadrangulatus in angulis glanduloso-setulosus ; bracteae ca. 3 mm longae sub- 

 ulatae ad pedunculi apicem insertae sparse glanduloso-setulosae tarde caducae. 

 Pedicelli 3-5 mm longi clavati compresso-quadrangulati in angulis glanduloso- 

 setulosi; bracteolae 1-1.5 mm longae triangulares acuminatae glabrae ad hy- 

 panthii basim insertae persistentes. Flores 5-meri. Hypanthium (ad torum) 6.5 

 mm longum 10-alatum alis 0.2 mm altis modice glanduloso-setulosis setulis 1-1.5 

 mm longis basi expansis plusminusve caducis alioqui glabrum ; calycis tubus 

 1 mm altus, lobis interioribus inconspicuis 0.4 mm altis obverse ellipticis apice 

 rotundatis minutissime glanduloso-ciliolatis, dentibus exterioribus 2 mm em- 

 inentibus linearibus apice seta unica glandulifera 1 mm longa terminatis. Petala 

 7-7.5 X 4.2-6 mm obovato-oblonga apice vix emarginata apicem versus ad 

 margines inconspicue erosa. Filamenta 6 mm longa ca. 4.5 mm supra basim 

 ventraliter cum glandula sessili ; antherarum thecae 7.5-8.5 mm longae oblongae 

 curvatae convolutae basi sub filamenti insertionem per 1.1-1.3 mm bifidae apice 

 dorsaliter poro 0.3 mm diam. Stylus 9 X 0.8 mm; stigma expansum 1.5 mm diam; 

 ovarium^ 5-loculare 1/2-inferum apice per 2 mm liberum truncatum minutissime 

 sparseque glanduloso-puberulum. Bacca ca. 1-1.3 cm longa oblongo-sphaeroidea ; 

 semina 0.8 X 0.4 mm pyramidata laevia. 



Type. Flowers white, fruit purple-black, abundant in talus forest between 

 Camps 3 and 4, Cerro de la Neblina, Terr. Amazonas, Venezuela, alt. 700-800 m, 

 7 Nov 1957, Bassett Maguire, John J. Wurdack, & Celia K. Maguire 41993 (holo- 

 type US 2342597). Paratypes. VENEZUELA, Terr. Amazonas. Cerro de la 

 Neblina: vicinity of Camp 3, alt. 650-1200 m, Maguire, Wurdack, & Bunting 

 36810, 36876; Canon Grande SSW of Cumbre Camp, alt. 1100 m, Maguire, 

 Wurdack, & Maguire 42491. 



Both relatives have terete hypanthia with glandular setae evenly distributed 

 over the surface. M. guianensis has 2-3 pairs of more-or-less coalesced bracteoles 

 at the hypanthium base, rather than a single pair as in M. neblinensis, while 

 M. poeppigii has stellulate-furfuraceous bracteoles and hypanthium as well as
