6. H. iNCRASSATO-LIMBATUM (C. Müll. Syn. ii. 8). H. laricino 
similimum, sed paulo robustius, folia e cellulis multo densioribus mi- 
neribus magis incrassatis et pachydermibus areolata, latius incrassato- 
limbata, superne denticulata, stipuleformia latiora, omnia utriculo pri- 
mordiali instructa igitur chlorophyllosa; perichetialia longius acuminata. 
Thece aggregate, longe pedunculate, nutantes, obovales, turgide, oper- 
culis cupulatis rubris longe et oblique subulatis; dentes exteriores lati, 
ciliis binis valde nodosis fragilibus inter dentes internos anguste carinatos 
tenuiter subulatos positis.— C. Müll. I. c.

fl. Itajahi in lapidibus sylvarum montosarum, Pabst. 
7. H. wrvALE (C. Müll. Syn. ii. 9). H. incrassato-limbato similli- 
mum, sed robustius; folia majora, haud incrassate sed laxius marginata, 
apice robusta argute serrata, nervo lato constanter in furcam sæpe pluries 
divisam partito multo longiore, cellulis majoribus minus chlorophyllosis, 
vel chlorophyllo carentibus; stipuleformia latius cordato-ovata, acumine 
recto latiusculo, minutius serrata et perfecte marginata obsoletinervia ; 
perichetialia lanceolato-acuminata, enervia, elongate reticulata, convolu- 
tacea. Thecæ aggregate in pendunculis longiusculis flexuosis rubris, pal- 
lescenti-rufze, turgide oblongz, sub ore coarctate, operculis cupulatis longe 
et oblique subulatis ; peristomium H. incrassato-limbati.—C. Müll. l. c. 
Hab. Venezuela, in montibus nivalibus Meridæ, Moritz, n. 70 et 150. 
8. H. TnourN1 (Mont. in Ann. Sc. Nat. ser. 3. iv. 86). Stipes 
elatus, foliis appressis obtusis, apice in frondem horizontalem ramis basi 
convergentibus inde ambitu rotundatam expansus. Folia ramea late 
ovata, apice obtusiuscula, mucrone brevi terminata, nervo sub apice eva- 
nido, limbo hyalino angusto apice denticulato, cellulis parvis rotundatis ; 
stipuliformia subcordato-ovata, obtusiuscule apiculata, nervo excurrente, 
limbo longius denticulato; ramulina parum angustiora; pericheetialia 
erecta, lanceolata, acuminata, integerrima. Theca in pedunculo brevi, 
oblongo-cylindracea, nutans, basi tuberculata, subito in pedunculum con- 
tracta; peristomii dentes intus valde trabeculati, processibus angustis 
pertusis, ciliis binis brevioribus, in membrana ad medium usque dentium 
longitudinis exserta impositis.
