534 Bryophyten. — Pteridophyten. - Floristik ii. Systematk. 



Besonderes Augenmerk legt Verf. auf die anatomische Untersuchung 

 der Blätter. Die Biattbündel von Hymenostomum squarrosum Br. germ. 

 und Fissidens decipiens De Not. gehören in die II. Gruppe der Haber- 

 landt'schen Blatttypen^ wobei sich die nahe Verwandtschaft der letzt- 

 genannten Art mit Fissidens adiantoides auf's neue zeigt. Die Spalt- 

 öffnungen an der Urne von Fiss. decipiens sind nicht rudimentäre^ 

 sondern zurückgebildete^ wie die Entwicklung derselben zeigt.

A preliminary report on studies of the embryogeny of Botrychitim 

 obliqiium Muhl. The author, contrasting the development of the sporophyte 

 of this species with that oiB. VirginianumSw. as described by Jeffrey, 

 proposes the new genus Sceptridiuni for the species of Boirychium hi- 

 therto associated as the „group of B. ternatiini"- , of which B. obliquum 

 is a member; these are : Sceptridium aiistrale (R. Br.) Lyon, 5. biforme

L'auteur montre que le Gypsophila fastigiata L. indique par Biroli, 

 et, d'apres celui-ci, par plusieurs autres auteurs, du Val Formazza 

 (Prov. de Novara), doit etre exclue de la flore italienne, et que le 

 Gypsophila que M. Rigo a recolte en 1902 dans les environs du lac de 

 Garde et a distribue sous le nom de G. fastigiata L. var. benacensis 

 Rigo est le G. hispanica Willk. jusqu'ä present connu seulement de 

 l'Espagne. (Cfr. Flora italica exsiccata, n«. 56.)
