Folia pallide viridia opposita imbricata subpatula, subsemicordato- 
triangularia, e margine postico superne concavo ensiformia, margine 
antico recurvulo longius decurrente subintegerrima, postico (auricula

Pl. ensiformis, sicuti a Tayloro descripta folia apice subtridenticulata, 
ceterum integerrima, habet; czteris caracteribus cum nostrati congruit.

Caudex prostratus divisus. Caules 5-pollicares validi rufescentes, inno- 
vando dichotomi vel, innovationibus cujusque lateris 2-vel 3-nis, 
fasciculatim et subflabellatim ramosi, ramis rectis rigidiusculis. 
Folia maxima pallide viridia tenuia imbricata, explanata fere, latissime 
semicordata subtriangularia obtusata, basi preelata antice decurrentia 
postice rotundata, supra medium, vel apice solo, spinuloso-dentata, 
dentibus 8-12, tenuibus, ineequilongis, rarissime circumcirea fere 
spinulosa ; cellulee majuscule subeequilateree pellucide. 
Flores 9 terminales (e dichotomiis). Bracteze foliis paulo longiores, 
unijugee erecte, basi a perianthio dissite, toto fere margine argutius 
dentate. 
Perianthia emersa, late campanulata vel suboblonga, ore truncato sub- 
bilabiato longiciliata, antice ala prelate spinosa aucta, in sicco haud 
raro a fronte, nec a latere, compressa. 
Andreecia flabelliformia, caulem comantia, ramulis plurimis, 18™™ longis, 
semel bisve furcatis vel subpinnatis, microphyllis constantia; bracteze 
saccate, cauli utrinque alte adnate, apice brevi patulo paucidentatee,

Heecce pulcherrima stirps differt a Pl. Jamesoni foliis prelatis obtusatis 
(nec rotundatis), auricula basali incurvo-appressa, nec recurvo-cristata, et 
perianthiis ex involucro emersis.
