332 PORELLA. 
oblonga, margine toto recurvo integerrima nisi basi hine decurrente 
in lobulos squamulasve fissa. 
Flores dioici: @ ad caulem (raro ad ramos) laterales. Bracteze subbijuge 
raro plures, intime foliis equimagnee ad 4 complicato-bilobe, lobo 
semiovali, lobuloque angustiore, eequilongo fere, subdenticulate ; 
bracteola zequilonga late ovalis, apice truncatnlo preecipue denticulata. 
Perianthia foliis sat longiora, late ovalia, compressa, antice bi-postice 
uni-carinata, fructu maturando facie anticd alte convexa (carinis 
obliteratis), posticd concava, medio tamen in carinam obtusam 
elevata, ore ineequaliter lobulato denticulatoque, demum bilabiata et 
decurva. 
Exemplaria originalia Jamesoniana cum meis satis bene conveniunt. 
Folia margine postico valde incurva, basi ipsa tamen vel plana vel 
cerispula. Lobuli foliolaque basi in alam profunde laciniatam super 
caulem producta, laciniis squamulas mentientibus. Caulis aliter non est 
“squamulifera,” neque in hac specie nec in P. arborea ceeterisque. 
6. PORELLA ACANTHOTA, Spruce. 
Hab. in monte Azudy Andium Quitensium, ad fruticum ramulos. 
F, lobus 2:0 x 1:4, lobulus 1-4x °35 ; ¢ 3,3 f 1:1 (1'8 ad basin decurrentem 
usque) X°83; br 2°55 br’* 23x11; per 40x 2:1, lacinie 1°5 ; elateres 
$3 spore x-—s5™. 
Elata pendula virescens. Caules 6—9-pollicares, laxe bipinnati, ramis 
ramulisque subinzequilongis, apice seepe attenuatis. 
Folia subcontigua, angulo fere recto patula, siccando immutata, bipartita 
complicata, carina perbrevi arcuaté; lobus semiovato-oblongus, 
margine supero, basi subsemicordata obsolete denticulata excepta, 
fere recto, postico apiceque plus minus rotundato repando, basi (7.e. 
in sinu) in auriculam 2-5-laciniato-spinulosam protractus ; lobulus 
lobo 4 brevior appressus ligulatus (4plo longior quam latus) rotun- 
datus, basi externa in auriculam Jongam spinoso-fimbriatam pro- 
ductus ; cellulase mediocres parum elongate opacie, trigonis magnis 
ad angulos auctie, subbasales sensim majores flavidee. 
Foliola lobulis subsequimagna, subimbricata, ligulato-oblonga rotundata, 
basi (hine preecipue) in cristam laciniatam longe decurrentia, laciniis 
triangularibus acuminatis. 
Flores dioici: ? laterales. Bracteee bijuge, intime folia subexcedentes 
profunde bifida, complicate, obtusie, plus minus denticulato-ciliate, 
lobo semiovali, lobulo ligulato fere squilongo triplo angustiore ; 
bracteola ovato-lanceolata sublingulata rotundata ciliolata. 
Perianthia alte emersa, f. caulinis duplo longiora, ovalia compressa, 
obtuse subplicata, ore truncato subconstricta, demum campanulata et 
macrostoma, 15-fida; laciniis lato-subulatis acuminatis iterum lacinu- 
latis denticulatisve, longit. =% perianthii. Calyptra perianthio duplo 
brevior globosa valida opaca, cellulis minutissimis 5-stratis con- 
formibus conflata, demum bivalvis. Capsula magna globosa, e peri- 
anthio in pedicello perbrevi valido vix emersa, vix ad basin usque 
4-partita ; valvule fragiles, demum in lacinias 3 ineequales longitu- 
dinaliter fissee. Cellule bistratee, exteriores sat crasse, apicem 
valvulz versus tam late quam Jongwe, infra medium autem plus 
minus elongate, omnes leptodermes nisi ad angulos ubi columnis 
rubro-fuscis fulcite ; stratum interius facile (sepe pedetentim)
