Gymnostomum Wimmerianum Sendtn. in Flora Ratisb. 1840. I. p. 50. 
Caulis simplex vel supra innovationibus 1 — 3 fastigiatis fascieu- 
latim ramosus, erectus, eirciter 3 linearis, dense caespitosus. Folia striete 
patula siceitate erispata, e luteo viridia, aetate corrupta, rufescentia; in- 
feriora breviora, lanceolata; superiora anguste lanceolata acutissima, supra 
basin eanaliculatam marginibus integerrimis involuta, indeque subulata. 
Areolatio basi tantum perceptibilis, e cellulis ordinatim seriatis teneris 
angustulis lucidis reetangularibus texta; supra basin condensata, ita ut 
folium obscurum appareat. Nervus fuscescens dorso in carinam productus, 
apice evanescens: Flores hermaphroditi. Vidi antheridia quinque eylin- 
drica rectiuscula fuscescentia, archegonia singula vel bina antheridiis duplo 
longiora, paraphysesque paucas lucidas tenues articulatas in perichaetio 
foliis e basi oblonga lanceolato - attenuatis figurato. Vaginula ovali-cylin- 
drica, fusco - lutea. Stipes tri-vel quadrilinearis luteus, subflexuosus, 
erectus, siccitate obsolete dextrorsum tortus. Theca ovali - eylindrica, 
angusta, plerumque obliqua vel subinclinata, orificium versus leniter an- 
gustata laevis, luteo-fusca ore aurantiaca; siceitate sub orificio eontracta. 
Operculum e basi depresso-conica  rubella in subulam ‚obliquam pallide
