Tu-LEJEUNEA, 269 
quasi-stipitata. Calyptra tenuis obovata. Capsula ovato-globosa in 
pedicello longiusculo exserta. 
Andreecia vel ramulo foliis caulinis breviore, bracteis 3-v. 4-jugis con- 
stantia; vel in ipso caule ramove terminalia longispica, bracteis 
6-10-jugis laxiusculis turgidis pro more parvulis. 
Speciei tam late distribute formas innumeras legi, limites tamen inter 
illas frustra queesivi, plurimis vix pro varietatibus (meo sensu) habendis. 
Solum in duas cohortes, sive subspecies, primo visu omnes se divi- 
dunt, se. 
1. flava (typica) ad arborum radices, in truncis vetustis et in rupibus 
habitans, colore in vivo amcene-vel flavo-viridi, in sicco fere semper 
flavescente; foliis oblique oblongis, nunquam semicordatis; foliolis 
raro ultra + alt. bifidis, basi rotundatis; bracteola angusta seepe triplo 
longiore quam lata. 
2. albida, in foliis vivis vel supra alias hepaticas reptans, colore tam re- 
cente quam post siccationem albicante; foliis vel oblongis vel sub- 
ovatis—hasi latioribus interdum semicordatis ; foliolis seepe ad dimi- 
dium usque bifidis basi minus raro subcordatis ; bracteola latiore— 
vix duplo longiore quam lata. 
Forme intermediz inveniuntur, que nexum completum inter has 
duas cohortes preebent.—Ad subsp. euflavam pertinet torma longicaulis, 
caulibus elongatis subramosis, ramisque parallelis stratificatis plagas latas 
in scopulorum facie ad fi. Negro cataractas, necnon ad arborum vicinarum 
pedem, efficiens. Folia dissitiora subfalcata. Amndreecia seepius termi- 
nalia longispica. Czespites unisexuales adveniunt, alii tamen plantas 
monoicas cum unisexualibus mixtas monstrant.—Forma dichotoma, flori- 
bus 9 fere constanter ex innovationum oppositarum furca ortis, crescit 
in M. Guayrapurina (alt. 900™) et ad S. Carlos fluvii Negro, in corticibus. 
Huic forme adsunt foliola interdum submajora, 4 folium subsuperantia. 
—Forme pusille variis locis vigent; earum una, ad Caripi prope Pard 
lecta, intermedia est quoad caracteres inter euflavam et albidam.—He 
omnes forme foliolis gaudent ab apice pro more ad 4 altitudinis solum 
bifidis; in eodem cespite tamen sepe adveniunt plantz quarum foliola 
ad 4 usque fissa sunt.— Planta Hibernica typica est, cum Swartziana 
originali bene conveniens, quoad colorem flavovirentem, foliola magna ad 
% fissa, ete. 
Subsp. albida quoque polymorpha est, formasque plures, inter se parum 
diversas, induit. Ad fl. Negro, in Muse folio carioso legi formam platy- 
stipam, foliolis paulo latioribus quam longis (3 x*85™™), bracteis foliis 
caulinis brevioribus. Forma subacutifolia, foliis plerisque (ac in typo) 
rotundatis obtusatisve, superioribus tamen interdum abrupte subacutis, 
czeterum nullo modo a typo diversa, crescit in fl. Negro sylvis super gramina 
(Pariane sp.) Forma parvi-angustifolia, recens albescens, siccando flavida, 
foliolis cordato-orbiculatis, nec aliter a typo diversa, habitat in trunco 
vetusto ad Caripi prope Pard. 
Obs. As several very distinct species are found in herbaria under the 
name “ Lejewnea flava”—even Lindenberg having sometimes given a form 
of the very distinct L. denticulata for it—I add a few diagnostic marks 
which may aid in identifying it. Although it runs into many forms, 
none of them are widely apart, and scarcely merit being called varieties. 
The two “subspecies” I have described above are better distinguished by 
their colour and place of growth than by any structural character; the
