devient Oe. caiicasica Simon. Quelques remarques sont faites sur Oe. 

 pimpinelloides var. major, Oe. Karsthia, Oe. Lachenalii var. parvula, Oe. 

 Foiicaudi; enfin le nom de Oe. Chalcidica est propose pour une espece 

 recueillie par Janka (Iter turcicum) et adressee ä Boissier sous le 

 nom de Oe. virgata Gris. 



Les conclusions de Simon sont commentees par M. Rouy, 

 d'apres qui on pourrait diviser le groupe de VOe. peucedanifolia en : 



1. Oe. peucedanifolia Pollich! auquel est rattache Oe silaifolia M. B. 



2. Oe. media Griseb., Oe. silaifolia Fouc. non M. B. 



3. Oe. filinendnloides Thuill., Oe. peucedanifolia Fouc. non Pollich.

A preliminary note on some branched speeimens of Lygino- 

 dendron. The stem of Lyginodendron has never so far been 

 observed to branch, but speeimens recently obtained from 

 Dulesgate, near Todmorden, Lancashire (Lower Goal

 also shows that they must have been aeriai, and not, as ge- 

 nerally accepted, basal or confined to the basal regions of the stem.

 grew in situ or not. It is concluded that the plant remains
