tertiariis tenuibus laxe reticulatis. Panicula laxe pauciflora terminalis 3-5 cm 

 longa ; flores 4-meri breviter (0.5-2 cm) pedicellati. Hypanthium (ad torum) 

 2.2 mm longuin graciliter 8-costatum sparse vel modice resinoso-furfuraceum ; 

 calycis tubus 0.9 mm altus, lobis 0.3 mm longis late rotundatis dentibus exte- 

 rioribus non eminentibus. Petala 3.1 X 1.4-1.7 mm obovato-oblonga apice obtusa 

 vel rotundata. Filamenta 2-2.2 mm longa ; antherarum thecae 2.8-3 mm longae 

 arcuato-subulatae, connectivo basi postice calcari 0.1-0.2 mm longo acuto armato. 

 Stylus 6.5 X 0.2 mm ; stigma punctiforme ; ovarium biloculare superum apice 

 sparse vel modice granuloso-furfuraceum. Fructus maturus ignotus. 



Type. Tree 6 m x 5 cm diam, flowers white, occasional in Cunuria forest, 

 Membaru-Kurupung trail, Pakaraima Mts., British Guiana, alt. 1000 m, 29 Oct- 

 4 Nov 1951, Bassett Maguire c0 I). B. Fanshawe 32404 (holotype US 2342458). 



G. obliqua has the axils of the inner pair of primary lower leaf surface veins 

 setulose, leaf blades only gradually and shortly blunt-acuminate, and acute calyx 

 lobes 1-1.5 mm long. Although G. obliqua was described by Cogniaux as having 

 3-4-locular glabrous ovaries, the material available to me shows apically gran- 

 ulose-furfuraceous 2-celled (occasionally 3-celled) ovaries. Both G. latifolia 

 (Nau<L) Triana and G. anomala Triana, with bilocular ovaries, have leaves quite 

 different from G. caudata. Calyptrella littoralis Gleason is synonymous with 

 G. anomala; however, I do not have available at present sufficient material to 

 establish the proper generic disposition of this Choco (Colombia) species. 



Neblinanthera TVurdack, gen. nov.

 antherarum thecae oblongae apice uniporosae, connectivo non prolongato basi 

 dorsaliter brevissime hebeti-calcarato antice non appendiculato. Ovarium omnino

 Capsula trilocularis loculicidaliter dehiscens ; semina ignota. Genus monotypicum.
