Jennings: Contribution to Botany of Isle of Pines. 155 



Near Nueva Gerona, May 15, 1904, A. H. Curtiss, No. 500; Savanna, 

 near Santa Fe, May 24, 1910, 0. E. Jennings, No. 561. General 

 Distribution: Isle of Pines and northern South America. 



The plants, as seen growing on the savanna near Santa Fe, were 

 small bushy trees rising to a height of ten feet, with much the general 

 habit of growth and appearance of Curatella americana (the "Sand- 

 paper Oak"). The flowers generally are white, tinged with pink, 

 the stamens being yellow. 



Note. Malphigia urens Linnaeus, and M. setosa Sprengel, Blain, 



Nos. 37 and 144 respectively, were reported for the island by Mills- 



paugh, but these records seem not to have been accepted in the 



North American Flora, XXV, Pt. II, 1910, the former species being 



credited to "Jamaica and the lesser Antilles," the latter to " His- 



paniola" only.
