6. CyatJiea pubcsccjis is common to Jamaica and Porto Rico, 

 (i 200-1500 meters.) 



7. Cyatlica Tussacii is common to Jamaica and Hispaniola. 

 ( 1 200-1 500 meters.) 



8. Cyathca nuiricata is common to Guadeloupe and Martinique. 



9. Cyatliea tcnera is rather widely distributed from Trinidad 

 through the Lesser Antilles. 



10. Besides the above are the species endemic in single islands : 

 Cuba, 3 ; Porto Rico, i ; Jamaica, 9 (three of which are still im- 

 perfectly known) ; Dominica, i ; St. Vincent, i ; Trinidad, 2. 



11. All of the well-known endemic species of Jamaica are 

 confined to altitudes above looo meters and some of them above 

 I 500 meters. 



12. The higher altitudes of Cuba and Hispaniola, whose flora 

 is unknown, are likely to furnish additional species. 



Attention was called to morphological and physiological fea- 

 tures worthy of investigation as follows : 



a. Marked structural differences in shape and arrangement of 

 leaf-scars supposed to be due to differences of nutrition and con- 

 sequent rapidity of growth. 



b. The function of certain gland-like structures at the bases of 

 the leaves in certain species and at the bases of the pinnae in 

 others. 



c. The origin of pendent lateral bud-like branches (especially 

 in CyatJiea dissolutd), organs of vegetative reproduction. 



Discussion followed. 



The meeting adjourned at 5:30 o'clock.
