Hab. Andes Quitenses, in monte Tunguragua, ad arbores saxaque, alt. 
2100-2800", ubi magis frequenter quam quisqualis Plagiochila in- 
venitur ; in ceteris Andibus rarius mihi videbatur. 
F 2°75 x20; ¢ gg; per 3°75™™ longa. 
Caules 2-3-pollicares, erecti vel ascendentes, parce monotropo-innovandi 
vel dichotomi, ramique apice insigniter circinati. 
Folia tulva fuscescentiave, subopposita vel plane alterna, conferta et 
vel distiche patula vel devexo-secunda, exacte cardioidea, basi lata 
semicordata, apice rotundata; margine antico subrotundato fere 
stricto recurvulo integerrima, cellulis marginalibus 2-3-seriatis 
cxeteris minoribus rufulis elongatis pulchre limbata, basi decurrentia; 
postico semiorbiculari longiciliata, ciliis sub 30, rectis rufo-badiis; 
cellule parvee subsequilateree pachydermes. 
Flores @ terminales, imnovati. Bracteze foliis sensim submajores, oblate, 
erebrius ciliates, perianthio appresse. 
Perianthia emersa rufa late campanulata compressa, hine vel utrinque ala 
ciliata aucta, ore lato oblique rotundato-truncato inciso-ciliata, ciliis 
subulatis, pulchre rufis. 
Planta ¢ humilior, magis ramosa. Androecia tenuia, lineari-fusiformia ; 
bractee seepe plurijugee, parvee, basi turgida antice in auriculam 
incurvam dilatate, 1- (raro 2-) andre. 
Var, elatior, robustior, 4-pollicaris, magis et seepe fastigiatim ramosa, foliis 
patulis vel subsecundis, pallidis, cellulis omnibus ciliisque fere con- 
coloribus.—Ad verram inter Ericeas in monte Tunguraqua.—A Pl. 
homochromate ramis equifoliatis et foliis margine antico integerrimis 
diversa. 
Pl. pachyloma varies exceedingly in aspect. Some forms have pale, 
others rufous foliage; some have it so bent back as to become secund, in 
others it is spread out nearly flat. In all forms the leaves have the 
semicircular postical margin equably set with long brown or red cilia, 
and the nearly straight antical margin bordered with narrow reddish cells, 
which give it a cartilaginous look, although not really thickened, as 
Taylor’s name implies.

Caules suberecti bipollicares di-vel trichotomi, sub flore 9 interdum sub- 
pinnulati, ramis apice  strictis vix circinatis, aliis subbasalibus 
flagellaribus. 
Folia subimbricata, horizontaliter patula, raro secunda, concoloria vel 
obscure rufo-marginata, dimidiato-ovata, basi subsemicordata, apice 
spina recté subulaté acuminata, spinula altera subantica plerumque 
divergente adjecta, rarius apice subeequaliter bispinosa; margine

toto margine 18 vel paucioribus, cellule mediocres, marginem 
apicemque versus sensim multo minores.
