Parvitate partium omnium atque cellulis alaribus pulchre chryseis 
majusculis laxis facile distinguenda species. 
90. Dicranum (Campylopus, Dicranodontium) chloro- 
trichum n. sp.; cespites lati pulvinati pollicares vel altiores sordide 
flavo-virides laxe cohaerentes sed foliis subulatis intricati inferne fer- 
ruginei vel nigriti; caulis dichotome ramosus, ramis apice plus 
minusve uncinatis; folia caulina erecto-patula falcata, madore parum 
laxiora, e basi cellulis alaribus pro foliolo majusculis laxis in ventrem 
levem congestis fuscis ornata in laminam anguste lanceolato - acumi- 
natam producta, margine erecto summitatem versus remote serrulata 
cymbiformi -canaliculata, nervo latiusculo flavo-reticulato percursa, € 
cellulis incrassatis flavis ellipticis basin versus magis rectangularibus 
arcolata; perichaetialia similia; theca in pedunculo mediocri innovando 
laterali glabro flavido siccitate et madore erecto parum flexuoso parva 
recta obovalis sulcata siccitate angusta saepius arcuatula, operculo 
minuto conico oblique rostellata, calyptra basi stricte fimbricata, 
peristomio brevi tenui normali. 
Habitatio. Prom. bonae spei, Montagu-Pass: Dr. A. Reh- 
mann, Coll. No. 53; in sylvis Knysnae; idem, Coll. No. 53b; in sylvis 
prope Blanco arboricolum, Oct. 1875: idem. 
91. Dieranum (Campylopus, Dicranodontium) perfal- 
catum n. sp.; cespites pulvinatuli virides inferne ferruginei teneri 
laxe cohaerentes sed foliiss subulatis intricato-adhaerentes; caulis 
subgracilis in ramos falcato-uncinatos dichotome divisus; folia caulina 
erecto-patula madore laxiora, e basi cellulis alaribus magnis multis 
teneris laxissimis in ventrem magnum valde pominentem congestis 
ornata in laminam anguste lanceolatam longe subulatum summitatem 
versus tenuiter serrulatam producta, margine erecta cymbiformi-canali- 
culata, nervo latiusculo reticulato flavido subulam carnosulam omnino 
fere occupante percursa, e cellulis minute rotundis viridibus incrassatis 
basin versus rectangularibus laxioribus areolata, dorso subulae tenuiter 
asperula. Caetera nulla. 
Habitatio. Prom. bonae spei, in sylvis Distr. Knysnae prope 
Esternek, Nov. 1875: Dr. A. Rehmann. 
A.D. chlorotricho proximo cellulis alaribus maxime prominen- 
tibus laxissimis jam diversum. 
92. Dicranum (Leucolomatacompacta)Rehmannin. sp.; 
cespites latissimi pulvinati robusti pallide lutescentes; caules usque 
bipollicares arcte adhaerentes in ramos appressos fissi flexuosi turges- 
centes, in apicem uncinatum brevem cuspidatum producti; folia 
caulina in axi nigrita tenui laxiuscule imbricata crispatula homomalla 
humore erecto -patula flexuosa longiuscula angusta, e basi cellulis 
alaribus paucis planis magnis laxis albidis teneris ornata semiam- 
plexicauli in laminam elongatam lineari-acuminatam setosam falcatam
