Hab. Andes Bogotenses, W'eir, n. 149; Brasilia, Sierra dos Orgaos, in 
truncis emortuis sylvarum antiquissimarum, Beyrich; Rio de Janeiro, 
Gardner; ad viam inter San Paulo et Jundiahy prope Olha da.Agua 
(1800 ped.), Weir. 
Caules prostrati, 3 unciam longi, ramos vage dispositos 2—3-lineares 
ferentes, latitudine cum foliis lineam dimidiam vix superantes. Folia pal- 
lide viridia. Pedunculus 3-linearis. 
H. guadelupensi similis, foliis autem brevioribus acumine latiore minus 
argute serrulatis diversa. 
This minute species appears to be closely allied to H. hyp- 
nacea; but both C. Müller and Hampe ascribe to that plant a 
dicecious inflorescence. 
76. H. suBFALCATA (Hampe in Ann. Sc. Nat. ser. 5. v. 305). Dense 
ezspitosa, expansa, ramosissima, flavescens vel rufescens; caulis com- 
pressus, basi purpureo-fibrillosus, prorepens; ramis apice aduncis, dense 
foliatis. Folia biformia; majora concava, basi plicato-contracta, immar- 
ginata, apice undulato-crispa, superne denticulata; nervis binis flavidis, 
solidioribus, ad apicem productis; cellulis basilaribus laxioribus, cæteris 
linearibus, pellucidis ; folia dorso papilloso-scabra; minora ovato-lanceo- 
lata, piliformi-acuminata, limpido-hyalina, nervis binis brevioribus, levia; 
pericheetialia latiora, longissime acuminata, apice denticulato-serrata, hya- 
lina, nodulis minutissimis lutescentibus adspersa, cellulis basilaribus luteis, 
nervis vix indicatis. Seta adscendens, uncialis, glabra, apice incurva, in- 
crassata. Theca elliptico-ovata, rubra, inclinata, ore nigricante ; operculo 
umbonato conico-subulato; peristomii dentibus exterioribus cruentis, lan- 
ceolato-subulatis, medio sulcatis ; interioris membrana lutescens, cruribus 
carinatis prominentibus, ciliis brevibus fugacibus interpositis; calyptra 
glabra, basi 8-fida, pallida, apice fuscata. 
Hab. Andes Bogotenses, Tequendama, Pacho et Canoas (2000-2500 
metr.), Lindig. 
Species ex auctore H. falcate simillima, sed foliis angustioribus nec 
plicatis diversa. 
77. H. cnactLIs (Mitt.). Folia compressa, concava, nervis ultra me- 
dium productis dorso serrulatis, marginibus superioribus denticulis apici- 
bus gemellis serrulatis, cellulis elongatis levibus; perichztialia ovata, 
subulata, enervia, serrulata. Theca in pedunculo superne scabro nutans, 
ovalis, collo sensim attenuato, operculo breviter subulirostrato ; calyptra 
apice scabra. 
Hab. Andes Quitenses, Jameson ; in sylva Canelos, Spruce. 
Folia viridia fulvescentia. Pedunculus ;-uncialis, gracillimus. 
Ab H. guadelupensi, statura paululo majore foliis latioribus et seta 
scabra recedit.

rum apicibus subcuspidato-imbricata, nervis tenuibus dorso superne ser-
