174 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



[Vol. 2, 1915] 



namely, vascular cryptogams and monocotyledons at the base, 

 followed in order by the dicotyledonous groups, Apetalae, 

 Polypetalae, and finally the Gamopetalae. With the latter the 

 lineal series is closed, since according to the consensus of 

 modern opinion they constitute the most highly differentiated 

 group of flowering plants. 



In the preceding lines I have endeavored to condense the 

 most prominent features relative to the life of the Botanical 

 Garden of Oaxaca. They are totally without pretense on my 

 part, although they would wish to carry to the minds of all 

 those who may read them the same high concept which I 

 myself have formed of such a progressive institution. 



In spite of the discouragement that I often feel about the 

 Garden, I have confidence in its final success. Everything 

 indicates that to-day the Republic is approaching rapidly a 

 better era, which will be effected through organic peace and 

 progress in its truest sense, since the horizon appears already 

 free from the dark clouds. 



In concluding, I wish to say that the Botanical Garden of 

 Oaxaca, after showing itself in the preceding lines in all its 

 smallness, has the honor of sending its older brother, the 

 Missouri Botanical Garden of St. Louis, its most cordial con- 

 gratulations for the Twenty-fifth Anniversary, wishing it long 



life and abundant prosperity
