63. H. TERRESTRIS (Mitt.). Dioica?, prostrata, subpinnata. Folia 
laxe compressa, media intermediaque anguste ovato-lanceolata acuta, 
lateralia longiora erecto-patentia subcomplicata concava, apicibus sub- 
flexuosis, nervis dorso denticulatis infra apicem abruptis, apicibus exstan- 
tibus, margine superne duplicato-serrulata, cellulis angustis basi laxioribus 
oblongis levibus; folia in caulis latere inferiore conformia, tenera; peri-

Hab. Andes Peruvianz, in monte Guayrapurina, ad terram (3000 ped.),

H. Cruegeriane simillima; foliis autem acutioribus, nullis obtusis in- 
termixtis. 
64. H. PARKERIANA (Hook.; Spreng. Syst. Veg. iv. 197). Doten: 
caulis procumbens, ramis pluribus adscendentibus simplicibus ramosisque, 
ruber. Folia compressa, superiora media intermediaque oblongo-ligulata, 
angulo obtuso terminata, inferne concava, lateralia patula angustiora 
acutiora, apice obliqua, inferne subcomplicata, inferiora acutiora, omnia 
transversim undulata, margine e medio usque ad apicem serrulata, flexuosa, 
nervis infra apicem desinentibus angustis, dorso apicem versus serrulatis, 
cellulis angustissimis limitibusque pellucidis levibus, basilaribus paucis 
latioribus fulvis; perichztialia longiora, late subulata. Theca in pedun- 
culo levi, oblonga, horizontalis, peristomii dentibus crassis, interni pro- 
cessibus flavis, in membrana usque ad J dentium longitudinis exserta im- 
positis; calyptra archegoniis paucis inspersa. 
Hookeria gigantea, Hornsch. in Mart. Fl. Bras. Musc. 67. 
Hab. Guiana, Parker, Schomburgk, Appun. Fl. Amazon, Martius; fl. 
Negro in sylvis rivuli Tarumá, ad ramulos, Spruce, n. 708; fl. Uaupés, 
loco Panuré, Spruce, n. 709. 
Caulis, ut in speciminibus parum perfectis invenitur, repens, radicans, 
ramos l-l} unciam longos emittens. Folia lj-linearia, straminea aureo- 
fulvescentia nitida, pulchre undulata. Pedunculus uncialis. Theca cum 
collo 2-linearis. 
Habitu ut videtur a speciebus H. Cruegeriane et H. undate similibus 
diversa. Foliatione autem parum recedens.

Folia compressa, complanata, transverse anguste undulata, lateralia patentia 
oblonga acumine brevi acuta, margine inferiore inflexo complicato, media 
intermediaque breviora, omnia nervis ultra medium productis, dorso apici-
