554 METZGERIA. 
Frondis lat. 3:0; furce long. 8°0; ¢ ss—gh; sete *15—-25™™. 
Pallida, siccando fulva fuscidulave, ciespitoso-stratificata. Frondes 
14-pollicares, intricate, acute dichotome, costa tenui subterete per- 
currente, limbo preelato hie illic decurvo-sinuato-constrictove, unde 
frondes undulato-crispe evadunt, supra glabree, subtus tota super- 
ficie dense setoso-villosie, setis pagine cellulis 4-6plo longioribus, 
rectis incurvis: flexuosisve marginalibus 1-2-(raro 3-)nis; cellule 
majuscule subeequilateree subincrassatie fere vacuze. 
Fleres dioici: 9 crebri. Bractea magna incurvo-concava late oblonga, 
apice obcordata—haud raro in frondulam dichotome fissam elongata 
—fere constanter basi utrinque 4—5-laciniata-lobulatave, extus mar- 
gineque setosa. Pistillidia brevia, 3-vel 4-paria. 
Calyptra clavato-pyriformis, longitudine =caulis lat., densissime setoso- 
hirta, incrassata, basi 8-cell., medio 4—5c., crassa, demum seepe infra 
apicem circumscissa. Czetera haud visa. 
Forsan M. Liebmanniane Lind. et G. Syn. Hep. 505, proxima; cl. 
auctores autem speciem suam describunt subtus setulis brevibus pubes- 
cens, (dum in nostra facies postica, setis longis crebris obsessa, potius 
villosa dicenda,) setisque marginalibus solitariis (in nostra plerumque 
binis). 
Obs. The “bract” being cloven at the base, into 4 or 5 rudimentary 
lobules on each side, is the initial step of the wing (cr limb) breaking up 
into distinct leaves. 
4, METZGERIA FRUTICOLA, Spruce. 
Hab. Andes Quitenses, in monte Tunguragua, ad fruticum ramos. 
Fr, lat 2°0; cell }3™™. 
Viridis, prostrata stratificata intricataque. Frondes 3—4-pollicares itera- 
tim (sub quinquies) dichotomee angulo subacuto. (70°-80°); costa 
valida subteres, supra cellulis 4-seriatis operta, subtus setis crebris 
sat longis villosa; limbus utrinque millimetrum latus decurvus, e 
cellulis sat magnis prominulis subpapulosus, apicibus latiusculis 
retusis, margine setosus, setis binatis cellulis 2-4plo longioribus. 
Flores dioici: Q@ subter costam sparsi; bractea annularis, antice tamen 
biloba, costata, extus tota setosa. 
A. M. claveflora certe diversa fronde magis divisa, costa subtus villosa, 
cellulis majoribus convexis; bracteis tota facie inferiore setosa. 
5. MEvZGERIA LEPTOMITRA, Spruce. 
Hab. In Andibus Peruvianis et Quitensibus, alt. 500-2500™., se. ad Tara- 
poto, in montibus Campana, Tunguragua, &e.; necnon in planitie ad 
fl. Negro cataractas ; ad arborum ramos, rarius ad saxa. 
Fr. lat 1°5-2°0; cell py; cilia -1; cal 8 x 35™™, 
Viridis tenuis tenera prostrata substratificata. Frondes2-pollicares lineares, 
iteratim dichotome, angulo fere recto, furcis 10™ longis,—aliis 
autem perbrevibus, aliis subelongatis—latiusculee, margine decurvo 
minute setuloso-ciliate, ciliis binatis rectis brevibus, raro cellulis 
paginee duplo longioribus, subtus tota facie—ad paginam sparse, ad 
costam densius—setulose; cellulae majusculee parum elongate ; costa 
mediocris compressula supra ¢c, 2 operta.
