MELASTOMATACEAE 



Leandra longisepala Wurdack, sp. nov. Fig. 31, A-J. 



Inter congeneros sectionis cum conjunctione foliorum submagnorum paulo 

 pubescentiumque et sepalorum magnorum bene distincta. 



Sect. Secundiflorae. Rami cum petiolis inflorescentiisque dense subsericeo- 

 strigosi pilis laevibus ca. 1 mm longis. Petioli 3-7 cm longi ; lamina membranacea 

 9-17 X 4—9 cm ovata apice anguste acuminata basi rotundata ad margines 

 distincte serrata dentibus ca. 6/cm et ca. 1 mm profundis singulis unisetosis seta 

 1-2 mm longa, breviter 7-plinervata jugo interiore 6-11 mm supra basim inserto 

 jugis exterioribus ad basim ipsam insertis nervis secundariis ca 4-5 mm inter se 

 distantibus nervis omnibus supra planis subtus graciliter elevatis, supra sparse 

 strigulosa pilis ca. 1 mm longis et 3-4/mm, 2 subtus in venis venulisque modice 

 strigulosa sed in superficie glabra. Inflorescentia ca. 12-17 cm longa cum ramis 

 arcuato-divaricatis ad 8 cm longis secundifloris. Flores inter se satis distantes 

 sessiles 5-meri ; bracteolae persistentes 2.5-3 X 0.3-0.5 mm lineares setulosae. 

 Hypanthium (ad torum) 2.3-2.5 mm altum densiuscule strigulosum pilis eglan- 

 dulosis plerumque 0.7-1 mm longis et modice cum glandulis clavatis sessilibus 

 vix 0.1 mm longis obsitum. Calycis tubus 1 mm altus, dentibus interioribus 

 ovatis rotundatis 1 mm altis, dentibus exterioribus ca. 2.5 mm longis oblongo- 

 lanceolatis anguste acutis extus et ad margines setulosis setis 0.5-0.7 mm longis. 

 Petala 3.6-3.8 X 1.5-1.6 mm ovata apice anguste acuminata. Stamina in magni- 

 tudine vix dimorphiea sed in forma isomorphica; filamenta 2.9-3.3 mm longa; 

 antherae 2.4—2.6 mm longae anguste oblongae apice minute uniporosae (poro 

 0.15 mm diam.), connectivo basi postice unicalcarato calcare 0.2 mm longo. 

 Stylus 6 X 0-3 mm ; stigma punctif orme ; ovarium triloculare apice glabrum et 

 in collum ca. 0.4 mm altum circum stylum protractum dentibus irregularibus 

 subsetulosis ; bacca ca. 6-7 mm diam., seminibus 0.5 X 0-35 mm leviter denseque 

 tuberculatis. 



VENEZUELA: Amazonas: Cerro de la Neblina, occasional on slopes just below escarp- 

 ment east of Camp 3, alt. 1600-1700 m; shrub 1.5-2.5 m, inflorescence branches pale pink, 

 petals pale translucent pink, stamens pale yellow, fruit deep purple; 27 Dec 1953, Maguire, 

 WurdacTc # Bunting 36914 (holotype, NY). 



Among the 5-merous species of Leandra sect. Secundiflorae, only L. franca- 

 villana Cogn. and L. longicoma Cogn. approach L. longisepala in sepalar 

 dimensions ; the former species has leaf blades beneath densely sericeous as well 

 as crowded flowers, while the latter has spreading longer stem, inflorescence, 

 foliar, and hypanthial hairs. 



Miconia pseudocapsularis Wurdack, sp. nov. 



M. lateriflorae Cogn. affinis sed cum foliis plinervatis inflorescentiae ramis 

 secundifloris floribus plerumque 5-meris connectivo antice distincte prolongato. 



Frutex vel arbor parva usque ad 10 m inflorescentia excepta glabra ; ramuli 

 teretes. Folia aequalia vel vix inaequalia; petioli 1-7 cm longi; lamina mem-
