138 HoMALO-LEJEUNEA. 
Perianthia maxima, foliis duplo longiora, fulva, a basi brevicuneata rec- 
tangulari- oblonga, valde compressa, fere plana, ex apice emarginato 
longirostria demum bilabiata, margine repandulo levi. 
Andreecia vel ramulum terminantia, flore 2 in ipso apice nullove, bracteis 
¢ 2-4-jugis, vel in medio caule posita, bracteis plurijugis foliis con- 
secutivis. Bracteze hasi naviculares subturgidze ultra 4 bifidee, lobulo 
lobo duplo breviore ovato-lingulato acuto. Antheridia magna, singula, 
raro binata. 
Obs. In specimens gathered on Pichincha the very apex of both stem 
and branches is minutely bifid, with a monogynous 9 flower in the fork. 
The next 2 or 3 pairs of leaves below the ? bracts contain antheridia— 
solitary, rarely twin; and very rarely a solitary abortive antheridium 
occurs In the axil of each 9 bract. The branchlets of each fork finally 
lengthen out and flower at the apex, like the first branches.

Caules e caudice prostrato tenui ramoso, cito dissoluto, ascendentes pendu- 
live cawspitosi elatinsculi (1—4-pollicares) graciles flexuosi, fere arhizi, 
pinnati, pinnis alternis distantibus—hine swepe pro parte deficientibus 
—superioribus iteratim dichotomis, flore 2 in furcis. 
Folia majuscula (*75—-1‘6mm.) parum imbricata decurva, siccando involuta, 
semicordato-ovata, subtriangularia, acuta, apice argute jee Mate loli 
serratave, raro integerrima, ad plicam decurrentia; lobulus (=1-$ 
folii) inflatus, margine seepius unidenticulatus, apice v. dentiformi v. 
confluente; cellulee mediocres parvuleeve pachydermes pellucide, 
utriculo pro more collapso. 
Foliola foliis subduplo breviora—in unica sp. fere equimagna—oblonga, 
rotunda, reniformiave, decurrentia integerrima, radicellas fasciatas 
apice subdivergentes (nec in orbem radiantes) perraro proferentia. 
Flores monoici (paroici)—interdum dioici (?): Q dichotomiales. Bracteze 
foliis raro longiores, lanceolate acute spinulose ciliateeve, minutis- 
sime (vel non) lobulatee—in unica sp. lobulo magis distincto, carina 
alata; bracteola latior, longius ciliata, apice integra v. emarginato- 
truncata. 
Perianthia emersa obcordata compressa brevirostria, margine alata cilia- 
taque, postice late obtuse unicarinata, vel rarissime carinis 2 sub- 
spinosis percursa. [Perianthium revera in dorso primitus bicarin- 
atum est, carinis obtusis basi haud longe dissitis, superne conniventi- 
bus, apiceque confluente 1—-(raro pluri-) spinis inermibusve, fructu 
autem maturato, obsoletis, indeque perianthium dorso alte convexum 
ecarinatum videtur.] Calyptra perianthio fere duplo brevior pyri- 
formis tenuis rufula, ultra medium in valvulas 3 regulares, tertia 
paulo latiore, fissa. Capsula globosa tenuis pellucida, ultra $ quadri- 
ralvis, cellulis bistratis, externis magnis quadrato-hexagonis, internis 
intus nodosis seepe ex parte dissolutis. Elateres pauci subapicales, 
cujusque valvyule sub 6 (utrinque 3), e cellulis valvularum mar- 
ginalibus, ceeteris duplo mimoribus quadratis, orti, preelongi, capsula 
haud multo breviores, unispiri, apice lato truncati. 
Andreecia hypogyna; bractee foliis rami fertilis parum mutatis con- 
stantes, monandre.
