474 PLAGIOCHILA. 
spinosa-ciliatave, spinis ciliisve 30-32, subulato-acuminatis 7 cellulas 
longis, rectiusculis ; cellulee majusculz zequilatere pellucide. 
Flores 2 terminales (seepe dichotomiales). Bracteze unijuge . foliis 
majores, margine antico fortius recurvo, toto margine longius 
spinoso-ciliatee, ciliis ad 13 cell. longis. 
Perianthia maxima alte emersa, clavato-oblonga compressa, antice sub- 
anguste spinoso-alata, ore bilabiata, labiis rotundatis crebre longis- 
sime ciliatis, ciliis tenuibus rectis, 
Var. (?) aspergillifera S., tenella, caule seepe fasciculato-prolifero, Innova- 
tiones 2-6-nas, apice solo foliosas aspergilliformes proferente.—Hab. 
Andes Quitenses in sylva Canelos. 
Obs. Non dubitandum est quod ill. Swartzius sub nom. “Jung. 
adiantoides” plures species complexus est. EK suo herbario tres formas 
J. adiantoidis examinavi, omnes specie plane diverse: sunt. 
1. Frustula sesquipollicaria olivaceo-et fulvo-viridia. Folia exacte 
opposita, 3°5x2-0™™, ovato-oblonga obtusata, utrinque subde- 
currentia, ipsissima basi excepta, circumcirca longe spinoso-ciliata, 
ciliis 839-40, aliis hamatis, anticis minoribus et remotioribus—Cum 
Pl. adiantoide Lindenb. ac nostra supradescripta bene convenit. 
2. Caulis (subcompletus) bipollicaris nigrescens fastigiatim subramosus. 
Folia 3-0 x 2°5™™ subopposita subsecunda badia ovato-orbiculata, 
antice subdecurrentia, circumcirea fere minute spinuloso-denticulata, 
dentibus brevibus subinzequalibus, margine antico late valideque 
recurvo revolutove paucidenticulato; cellule equilaterze, omnes fere 
zquimagnee. Perianthia alte exserta compressa hamata, ad suturam 
anticam incrassata non autem alata, ore truncato minute denticulata. 
—Species forsan adhue nondeseripta, quum neque cum Pl. adiantoide 
nec cum Pl. macrostachya Lg. convenit. 
3. Frustulum pollicare bifurcum. Folia badia obscure per paria approxi- 
mata, 1-4 1°5™™, ovato-orbiculata subtruncata, margine hic illic 
brevi-pauci-denticulata. 
21. PLAGIOCHILA VIRENS, Spruce. 
Hab. ad fruticum ramulos juxta fl. Bombonasa, in Andium radicibus 
orientalibus (Junio, 1857). 
F 52x 4-0, c a; per 0x 4:0™™, 
Viridis tenella. Caules bipollicares apice semel bisve furcati. 
Folia pro plantula magna imbricata distiche patula prelate semiovata 
rotundata; margine antico recurvo breviuscule decurrente basi 
pauciciliolato, medio subintegerrimo, apicem versus spinuloso ; mar- 
gine postico toto fere apiceque .spinuloso, basi plerumque recurvo- 
cristato ; dentibus omnibus 40-44, parvis, 3-7 cellulas longis, basi 
dilatatis apice setaceis; cellule majuscule pellucidee aquilatere, 
ad plicam anticam paulo longiores, pariete subincrassato. 
Flores dioici: @ in furca ramisque terminales. Bractea appressze foliis 
perpaulo majores, subconformes, nisi pro margine toto spinuloso 
(d. 50). 
Perianthia vix subemersa campanulata ore compresso bilabiata, labiis 
erebre (haud longe) ciliatis, antice alata, ala angustiuscula pro more 
dentata. Capsula subglobosa,
