1. Hy@ro-LEJEUNHA CATINULIFERA, Spruce. 
Tab. Andes Quitenses in nemoribus subalpinis, alt. 3000-3500 m., supra 
pagum Quisapincha, ad filices et folia emortua; in montibus Altar 
et Mulmél, in truncis vetustis. 
F -9x°65; lob -4x°15; cm. Ay-dk; fl 55x °75, 5 x 65; br. lob 1:3 x 6, 
10x ‘5; br’ 1:0x -4—"5; per 1°6 x 65, 1°4 x °65™™. 
Pusilla, pallide sordide flavida rufave tenera czespitosa. Caules 1-1}- 
pollicares pinnatim v. subfastigiatim ramosi, ramis_breviusculis 
assurgentibus erectisve, aliis paucis elongatis microphyllis. 
Folia densiuscule imbricata, basi angusta inserta, patentia v. erecto- 
patentia, decurvo-concava, semicordato-ovata rotundata, fere dimi- 
diata, medium versus sinuato-complicata, lobulus plus duplo brevior 
inflatus ovalis obtusus acutusve, subsaccatus, bis introflexus tamen, 
unde anguste fusiformis videretur; cellulae mediz mediocres zquali- 
ter hexagone subleptodermes pellucide, marginales minores subqua- 
drate. 
Foliola subcontigua 4 folium superantia subcordato-reniformia-orbicula- 
tave, concava, margine toto incurvo, apice rotundato v, leniter re- 
tuso. 
Flores dioici: ? crebriusculi sed plerumque steriles, terminales, innova- 
tione unilaterali v. szpissime binis oppositis suffulti. Bractes 
erect foliis longiores ad } bilobze, lobo subovali obtusato, lobulo 
longe minore ligulato subtruncato; bracteola utrinque connata ovalis 
obtusa v. obtuse apiculata v. denique leniter emarginato-bifida.— 
Foliolum supremum infraflorale ceteris multo majus, orbiculatum 
subemarginatum. 
Perianthia alte emersa pellucida, clavato-pyriformia plus duplo longiora 
quam lata, compressula, rotundato-truncata rostellata, antice 1-cari- 
nulata, postice obtuse 2-carinata, demum ore in lobulos 5 cuspidatos 
i levia. Calyptra oblongo-globosa perianthii dimidium inferiorem 
replens. 
Inter Hygro-Lejeuneas et Archi-Lejeuneas fere media; teneritate, foliolis 
basi cordatis et perianthii carinis levissimis magis ad priores, foliis bracte 
isque integerrimis ad posteriores, accedit. Neque a Brachio-L. laxifolia 
Tayl. longe distat; habitu necnon floribus 9 normaliter dichotomialibus 
eadem; differt foliis rotundatis, lobulo haud crenulato, et foliolis cordatis 
incurvo-concavis—nec basi decurrente recurvis (qualia in B. L. laxifolra). 
—L. Loxensis Gotts. nostree certe affinis, folia habet acuta, foliola rotunda 
subplana. 
The leaves are very concave, or, when seen from above, convex, so that 
in the dried specimens they have a bullate appearance; this, and their 
pale colour, the narrow twice-infolded lobule, and (above all) the cordato- 
orbicular stipules, suffice to distinguish the species from Archi-Lejeunea 
unciloba and all its allies. 
The microphyllous branchlets are not male spikes, but possibly indi- 
cate a tendency to revert to a former monoicous condition.
