Hillebrand 1870. 
o 
Entodonti Solanderi Angstr. Tahitensi persimilis, sed hicce 
differt jam foliorum reticulatione laxiere atque theca cylindrica 
subarcuata. 
86. Neckera (Rhystophyllum) hawaiico-pennata n. sp.; monoica; caulis 
primarius ramosissimus, ramis elongatis flexuoso-curyatis perangustis 
breviter ramulosis laete flavido-lutescentibus latissime dilatatus; 
folia caulina laxe irnbricata madore valde patula, ramulos patentes 
plumosos gemmula minuta conclusa terminatos constituentia, di- 
stincte transversim undulata madore autem planissima pallidissima 
parva, e basi angustiore parum asyinmetrica in laminam anguste 
oblongam ligulato-acuminata, caviuscula, nervis binis brevissimis 
subobsoletis leviter exarata, e cellulis angustissimis summitatein 
versus magis ellipticis minoribus albescentibus areolata; perichae- 
tialia multo majora, e basi lato-vaginata in subulam longiusculam 
strictiusculam attenuata; theca immersa anguste cylindrica, oper- 
culo conico rostrato erecto; peristomium longum: externi dentes 
angusti longe subulati articulati lutei valde cristati, interne illis 
aequilongi longissime capillares basi linea longitudinali divisi. 
Habitatio. Insulae Hawaiicae, sine loco speciali, sed certe ex 
regionibus elatioribus: Dr. Hille brand. 
A. N. pennata statura gracili jam remote differt; species 
distinctissima elegans. 
87. Neckera (Omaliopsis) aquatilis n. sp.; caulis secundarius elongatus 
tluitans viridissimus, ramis brevioribus basi et summitate angu- 
stioribus curvatis viridissimis irregulariter pinnatus; folia tenuia 
parva dense irnbricata surculum planissimum sistentia madore patula, 
e basi angustiore ligulato-ovata rotundato-obtusata, acumine bre- 
vissimo latiusculo terminata, planiuscula brevissime obsolete binervia, 
integerrima, e cellulis viridissimis veluti conflatis angustissimis 
areolata. Caetera ignota. 
Habitatio. Insulae Hawaiicae, East Maui, 8000 ped. alt. in 
aquis: D. D. Baldwin. Riemenschneider misit 1875 ex 
Honolulu. 
Neckerae glabellae similis, sed tenuitate partium omnium jam 
remotum. 
88. Neckera (Omaliopsis) Baldwini m sp.; caulis secundarius supra- 
bipollicaris strictus vel curvatus, simplex vel ramulis brevissimis 
patentibus divisus viridissimus latifrondeus aequalis summitate obtu- 
satus, basi attenuatus minutifolius; folia caulina dense irnbricata 
planiuscula viridissima majuscula, e basi decurrente angustiore 
asymmetrico-oblonga latiore ligulato-obtusata, acumine brevissimo 
latiusculo terminata, nervis binis tenuissimis longiusculis percursa, 
summitate distincte minute denticulata, e cellulis viridissimis inferne 
angustissimis apice ellipticis minoribus areolata. Caetera ignota.
