agreement in the gymeceum, placentas, ovules, fruits and seeds. Moreover, 

 their relation, when coupled with the parallelism in their anatomical character, 

 e.g. in the perforation of vessels , becomes still more complete. Some resem- 

 blance to the Batidales is indicated by the dimerous gynsec-aum in both 

 Salicaoaffl and Batidacear 5 . Further, the Salicales are regarded by some 

 authors as comparable with the Myricales and with the Juglandales 35 . Now, 

 take fruits and seeds as the criterion for comparison, then the Salicales should 

 be taken far away from their present position and put close to the Parietales. 

 Next, take into consideration for classification the absence of perianth in 

 the Salicales, and you will find the latter series quite right in its present 

 place near the Juglaudales, Fagales , Batidales or Myricales. 



Then, follow the Garryales ft) after ENGLER'S system. As to this series, our 

 knowledge is too incomplete for an understanding of its relation to other series. 



Next, come the Myricales^. They are comparable with the Fagales, 

 Salicales and Juglandales in this point or that 7 ^. 



Here, ENGLER places the Balanopsidales 8) . This juries is somewhat allied 

 to the Geraniales, as is indicated by the agreement in the structure of the 

 ovules of the Balauopsidaceae and Euphorbiacese' . Consequently, its natural 

 position is movable from this place to that, from proximity to the Myricacese 

 far away to near the Euphorbiacese. 



Then, follow the Leitneriales. It is difficult to deny that they are related 

 to the Resales, when we consider the resemblance of the Leitneriacese 10 ^ and 

 Harnamelidacese in the resin-ducts in the medullary-sheath. 



Here, ENGLER places the Juglaudales. Their relation to the Myricales, 

 Salicales and Verticillatte has already been stated. They are also allied to some 

 extent to the Fagales, and Urticales' . But, a greater resemblance is to be found in 

 the Julianiales'- ; . The alternate, exstipulate, iniparipinuate leaves and the resinifer-
