Bryophyten. — Pteridophyten 101 



Portugals über Spanien, Frankreich nach England zieht, unterscheiden. 

 Verf. giebt nun eine Zusammenstellung der mediterranen Elemente der 

 mitteleuropäischen Flora (61 Arten), wobei er stets die Nordgrenze der 

 geographischen Verbreitung angiebt. Diejenigen Arten nun, die dem 

 mediterranen Gebiete eigen sind, tragen einen ausschliesslich xerophilen 

 Charakter, diejenigen Arten, welche die Moosflora des borealen Gebiets 

 zusammensetzen, besitzen meistens vortreffliche Hygrophyten-Anpass- 

 ungen. Die ersteren Anpassungen lassen sich in 3 Typen zusammen- 

 fassen : 1 Trichostomum-Typus (Gattung : Hymenostomum, Gymnostomum, 

 Weissid, Trichostomum, Tortclla, Timmielld), 2. Crossidium-Typus (Ptery- 

 goneuron, Crossidium, Aloi'na), 3. Cylindrofhecium-Typus (Braun ia, 

 Brvum. Cryphaea, Leskea, Cylindrothecium und Scleropodium). 



Verl' erwähnt noch diejenigen Arten, die absolut mediterran sind, 

 ferner die Arten, welche im mediterranen Gebiete weniger auftreten oder 

 in demselben keine Variationsfähigkeit erreichen und endlich die That- 

 sache, dass das Genus Tortula im europäischen Mediterrangebiete ein 

 selbständiges Centrum besitzt. Matouschek (Reichenberg).

I pon examination oi the scanty preserved speeimens of the puzz- 

 ling moss-genus Osculatia De Not., the author finds it to be identical 

 with another South American moss Bryum globosum Mitt. He redescri- 

 bes the plant and names it Bryum (Brachymeniuni) columbicum. It 

 oecurs in the Andes. He also discusses the characteristics of the genus 

 Schwetschkea C. M., and Claims a basal membrane is present in the inner 

 peristome of at least some of the species. He refuses to admit it into the 

 genus Leskea gracillima Tayl. A. Gepp.
