omnino magnopere minutissime tessellato-squamulosa, 
7.5-10 cm. longa, 6-7.5 cm. lata (parte centrali); nervo 
centrali robusto, nervis secundariis valde arcuatis, terti- 
anis angulatim 45° patentibus, nervis omnibus supra in- 
conspicuis sed subtus prominentioribus. Inflorescentia 
erecta, gracillima, pedunculo usque ad 16 cm. longo, 
eylindrico. Spatha viridis, vivo valde reflexa, membra- 
nacea et hyalina, oculo armato minutissime squamulosa, 
nervulis prominentibus, lanceolato-elliptica, apice acutis- 
sima, 4.5 cm. longa, 7.5-8 mm. lata. Spadix erectus, 
albidus, usque ad 5 cm. longus, cylindricus, comparate 
tenuis (3 mm. in diametro, ad apicem non attenuatus), 
stipite 1.5 cm. longo suffultus. Flores valde regulares, 
subquadrangulares. 
From other species with similar hastate leaves, 4n- 
thurium pluviaticum can be distinguished by its long- 
stipitate and unusually slender spadix, by its very abbre- 
viated caudicle and by the small size of all its parts. It 
would seem to resemble the type of Anthurium chloro- 
carpum Sodiro in some respects, but its leaves are smaller, 
more acuminate and more nearly membranaceous, and it 
has an inflorescence which, in addition to the stipitate 
spadix, shows important morphological differences. 
The specific epithet of Anthurium pluviaticum recog- 
nizes that the plant grows in an area which has one of the 
world’s heaviest rainfalls.
