PLAGIOCHILA. 487 
Var. Peruviana, rufescens, foliis subdissitis siceando tam recurvo-con- 
strictis ut linearia viderentur. In Andibus Peruvise orientalibus, ad 
arborum truncos in humidis. 
Obs. In this species, all the leaves, of both stem and branches, have 
the margins so strongly recurved at the base that they seem cuneate, 
and the general outline of the leaf obovate, whereas when flattened out 
they are found to be widest near the base, z.e. obliquely ovate, or seri- 
ovate, rarely semicordate. Jn the variety Peruviana the whole plant has 
a rufous tinge ; the leaves are rarely at all imbricated, and in drying the 
margins are so strongly rolled back that the leaves seem widely-set and 
linear ; yet when expanded by moisture their form and toothing are not 
sensibly different from those of the typical form. 
A plant gathered on Mt. Campana has regularly, though laxly, pinnate 
stems, with sometimes as many as 12 pinnze on each side, and a pinna 
usually bears a @ flower, apparently about midway, in reality the upper 
half is a subfloral innovation. This peculiarity, and the rather narrower 
leaves, 5- or 6-toothed at the rounded apex but entire elsewhere, lead me 
to suppose it a distinct species ; but as | have only very young perianths, 
Iam unable to describe it fully.

Caudex repens brevis subramosus. Caules 4-pollicares flabellatim sub- 
bipinnati, vel ex parte subdichotomi, basi e foliis ad squamulas 
breves redactis ad speciem denudati, dendritici; ramis primariis 
paucis patentibus, infimis multo longioribus, 
Folia flavo-viridia imbricata patula vel subsecunda, late semiovata (ramea 
semiovato-oblonga) margine antico recurvo basi longe oblique decur- 
rente integerrima, postico apiceque brevi-spinulosa (spinulis sub 12) 
basi edentata caulem subamplexantia ; cellula mediocres subelongate, 
trigonis conspicuis intercalatis. 
Flores 2 terminales. Bracteve foliis majores semicordato-oblongze magis 
spinosee. 
Perianthia emersa oblato-campanulata, basi subinflata, apice latiora com- 
pressa rotundata crebre spinosa, antice tota longitudine alata, ala 
lata superne spinosa, interdum acie etiam postica alata. 
Planta ¢ tenuior, laxe bipinnata, ramulis interdum fureatis, apice flori- 
feris. Bracteze 7-10-jugze julaceo-appressie, tenerrime, elongato-

ovali-globosa stipitata.—Folia caulina rameaque subangustiora, seepe 
semiovalia, angulo 45° erecto-patenteia. 
A Pl. letevirente satis distincta videtur. Caules sunt robustiores, magis 
flabellatim divisi, ad ultimos ramulos latius foliati ; folia omnia semi- 
ovata, nulla rhomboidea, siccando parum mutata nec revoluto-linearia ; 
perianthia denique majora et multo latiora, spinoso-alata, ipso apice 
compresso-plana et insigniter dilatata.
