subdivisi, apice florente innovandi, seepe dichotomi, haud raro ex in- 
volucro innoyationes 2-6-natas distiche proferentes, ex eo fasciculato- 
dendroideove-ramosi; rami eodem modo innovandi vel simplices. Folia 
magna, 4-7™™ longa, sat lata, in vivo seepius amcene viridia, siccando 
pallida, flavida badiave, neque rufa nec rosea; in speciebus Andinis 
semper opposita, vel saltem per paria approximata, basi postica lata ple- 
rumque semicordata, auricula vel recurvo-cristaté vel appressa, caulem 
et folia contraria imbricante, margine utplurimum longe ciliata spino- 
save, raro solum denticulata, rarissime integerrima ; cellule majuscule, 
in paucis mediocres, rarissime parvule. oliola constanter nulla. Peri- 
anthia semper bracteis involucrata, plerumque insigniter alata. An- 
drecia in plerisque speciebus terminalia, composita, eleganter flabellatim 
dichotoma, ramis tenuibus ubique bracteiferis, bracteis minutis monan- 
dris ; in perpaucis ad plantze ab initio dichotomz ramos apicalia media- 
nave, spicam fusiformem sistentia, bracteis majoribus polyandris (anthe- 
ridiis ad 10). 
Hab. Plantee in genere nobilissime, foliis ad quartam pollicis vel etiam 
ad tertiam partem attingentibus, seepe pulcherrime ciliatis, Andes sylva- 
ticos habitant, majore copia in regione temperata, inter 1500 et 2800 
metr. altitudine, adusque 3400 metra tamen ascendunt; unica specie 
excepta, secus fluminis Orinoco origines inventa, in planitiem nusquam 
descendunt. Loca umbrosissima diligunt, ubi ad arborum  truncos 
ramulosque, necnon sed rarius ad rupes, rarissime sub fruticibus in ipsa 
terra vigent. 
Obs. These fine plants present much uniformity of coloration, being 
when fresh usually of a pleasant green, verging on the one hand to 
yellow, on the other to olive, and are never (not even when dried) either 
rose, or red-brown, or golden; although Pl. conspicua approaches the 
latter tint.
