1. M. pubescens (Schrank.) Radd. 



Dioica, perfecte plana optimeque undulata, et antice et po- 

 stice ubique densissime villosa, strato corticali caulis maxime 

 indistincto. — Fig. 1. 



2. M. frontipilis Lindb. n. sp. 



Dioica, convexa, haud undulata, caule et antice et postice 

 dense, alis foliaceis solum antice remotius et in marginibus 

 dense subvillosa, strato corticali caulis indistincto. — Fig. 2. 



3. M. filicina Mitt. 



Dioica, convexa, haud undulata, antice semper glaberrima, 

 postice in caule haud vel sparsissime, in marginibus sparse, 

 in ipsis alis foliaceis numquam tamen setoso-pilosa, strato 

 corticali caulis distincto. — Figg. 3.

4. M. Liebmanni L. G. 



Dioica, plana optimeque undulata, postice ubique, prsesertim 

 in caule, dense villosa, pilis breviusculis, e basi divaricata 

 irregulariter sursum nutantibus et curvatulis, marginalibus in 

 piano alarum positis, vix umquam geminis, caule antice a 4 

 —6, postice a 6—9 cellulis corticalibus obtecto. — Figg. 10. 



5. M. dichotoma (Sw.) Nees. 



Dioica, convexa, haud vel vix undulata, postice ubique, prae- 

 sertim in caule et marginibus, dense, in alis remotius, setoso- 

 pilosa, pilis longis, e basi divaricata deorsum curvatulis vel 

 strictiusculis, marginalibus in piano alarum positis, vix um- 

 quam geminis, caule antice a 3—5, postice a 5 — 8 cellulis 

 corticalibus obtecto. — Figg. 7. 



6. M. myriopoda Lindb. n. sp. 



Dioica, maxime convexa, haud undulata, postice in caule et 

 marginibus, haud in alis, densissime setoso-pilosa, pilis lon-
