alt. 1500-1800: forma foliis aureis; etiam in descensu montis 
Chimborazo, alt. 1200: forma foliis badiis dissitis—Planta formosa 
cujus typus (foliis apice inciso-ciliatis, non autem bifidis) in Antillis 
primum inventa fuit.

Caules 4-9-pollicares, in ceespites seepe pendulos congesti, tenues flexuosi, 
subsimplices et innovando-elongati, vel parce suberecte ramosi, 
ubique foliosi. 
Folia nitida, aurea vel badia, subimbricata vel dissita, squarrose disticha, 
prelonga, semiovato-lanceolata longe sensim acuminata (i.e. scal- 
pelliformia), apice profunde (ad +) inciso-bifida vel ineequaliter 
trifida, laciniis subulatis acuminatis, raro solummodo 3-4-spina, 
cxetero margine plerumque integerrima, rarius postice 1-2-denticulata ; 
cellule tenues, 7-77 longe, bis terve longiores quam late, pachy- 
dermes. 
Foliola (raro ubique preesentia) foliis 2-8plo breviora, subulata, flexuosa, 
apice integra vel bifurca. 
Flores 2 terminales, ex innovatione subrecte continua scepe ad speciem 
laterales. Bractece 2-4-jugee arcte imbricatee late ovatee acuminatee 
toto margine ineequaliter spinosee. 
Perianthia involucro subeequilonga, cuneato-campanulata vel subobovata, 
inflata subplicata, ore compresso incurvo oblique arcuato pluri- 
spina. 
Differt a ceteris omnibus fere Plagiochilis cellulis foliorum elongatis 
quasi-Hypnoideis, involucris capitatis polyphyllis et perianthiis sub- 
plicatis. Nostra var. Andina, ob folia apice bicrura Herbertam simulat. 
2, PLAGIOCHILA TUNGURAGUENSIS, Spruce.

Caudex repens tenuis brevissimus. Caules elati, 4-6-pollicares, assur- 
gentes pendulive, iteratim (ad sexies) innovandi, vel monotropi vel 
ex parte dichotomi. 
Folia badia subimbricata, distiche patula vel plus minus decurvo-secunda, 
semiovata, apice subacuto pauci-dentata, dentibus brevibus 3-5, 
margine antico subrecto recurvo basi longe decurrente, postico con- 
vexo superne subrepando ; cellulee majusculee pachydermes, inferiores 
duplo longiores quam late, subapicales vix elongate, oblongse vel 
subrotundo-hexagonee. 
Flores 9 capitati, Bractece 3-jugze, foliis majores, grosse subspinoso- 
dentate. 
Perianthia parum emersa, late campanulata, compressa, hinc ala brevi 
lineari aucta vel exalata, ore spinoso-dentata. 
Species nobilis, cum nulla alia confundenda, involucris conspicuis ad
