oblonga acuta, margine antico recurvo integerrimo, rarissime 1-—2- 
denticulato, postico a basi fere apiceque dentato-longispino, dentibus 
circiter 8, subulatis acuminatis, 2 vel 3 apicalibus spe prelongis 
unde folia 2-3-fida evadunt ; cellule majuscule, duplo triplove 
longiores quam lata, pachy dermes. 
Flores Q terminales , innovati. Bractew propriz nullee. 
Perianthia exserta, basi nuda, parva, oblonga obovatave tetragono-com- 
pressa, exalata, ore subbilabiato longispina. 
Ab omnibus Pl. frondescentis formis differt foliis margine postico toto 
fere nec solum apicem versus spinosis, dentibus longioribus, reti cellu- 
larum laxiore, denique perianthio exinvolucrato. A Pl. macrifolia foliis 
et preecipue perianthiis longe brevioribus distincta. Pl. tenwis Lindng. 
Sp. Hep. t. 10, habitu similis, diversa est foliis apice solo inciso-dentatis

Obs. Jameson’s original specimens, on which Lindenberg founded his 
Pl. procera, were probably ¢ gathered in the same places as my own; for 
Baivos, the locality cited by” him, is a village at the foot of 7 unguragua, 
between that mountain and the Forest of “Canelos, which begins a little 
lower down the same valley, of the river Pastasa.
