tumve versus 5-8-10-plicata, ore constricto denticulata demum pluri- 
fida. Calyptra plus duplo brevior obovato, basin versus pistillidiis 
20 vel pluribus obsita, basi ipsa 4 cellulas, paulo altius 2 cell., 
dimidio supero autem cellulam unicam crassa. Capsula maxima, 
ealyptra imo longior eandemaue apice cito rumpens, oblongo-rotunda, 
pedicello tenuiusculo longiusculo suffulta. 
Andreecia in planta propria, medio canle posita; bractez foliis caulinis 
consecutive, minores, paucijugee, basi erecto-ventricosa arcte imbri- 
cate, raro dente antico suprabasali auctz ; antheridia (fragmentaria) 
solitaria videbantur.* 
Var. densifolia 8., foliis confertis prelatis, basi tam antica quam postica 
altiuscule per paria connatis, apice oblique truncato-uni-bispinosis 
seepeve muticis et rotundatis, margine antico late valide recurvis.— 
In ascensu montis Tunguragua, ad truncos. 
Var. subintegra S., foliis subimbricatis apicem versus sensim angustatis 
obtusatis subacutisve, raro oblique bidentellis, basi subconnatis ;

Obs. The habit of this curious species is so exactly that of a Plagiochila, 
especially when (as is often the case) the leaves are decurva-secund, that 
before I found the perianths I placed it in that genus. The following 
species is still more like a Plagiochila, and at first sight would unhesi- 
tatingly be put along with the “cristate.” The presence in both species 
of a tuft of white radicles at the base of each pair of leaves suffices, along 
with the turgid perianth, 5-10-plicate at the mouth, to place them in a 
quite different genus, near to Jung. macrocalyx Montagne. 
2. SYZYGIELLA PECTINIFORMIS, Spruce. 
Hab. in sylva Canelos, in stillicidiis. 
F30xX1.75 Cye-zs™™. 
Cespitosa pulchre rosea purpureave ; caules 2-3-pollicares simplices fur- 
cative, subtus e foliis basi postica ampliatis recurvisque cristati (ad 
Plagiochile cristate instar). 
Folia conferta, pectinatum disticha, in planum patula decurvulave, oppo- 
sita sed non connata, longe semicordato-triangularia, a basi preelata 
sensim ad apicem angustum truncuto-excisove-bidentatum usque 
angustata, dentibus brevi-subulato-setaceis, integerrima vy. solum 
repanda angulatave ; cellule mediocres pellucide, trigonis conspicuis 
seepe intensius coloratis.—Flores haud inveni. 
A 8. plagiochiloide distincta erit foliis eequilongis duplo autem angusti- 
oribus, fere ab ipsa basi ad apicem usque sensim attenuatis, tam longis 
confertisque ut caules pectinati videantur. Quum autem planta sterilis 
solum adest, utrumque pro var. preecedentis, utrumque pro specie propria 
habenda, animo suspensus sum.
