Antillanae, I, 1899, p. 227) to C. laurijolia, represent a form having a 

 large leaf with an obtuse base and a strong wide petiole, very much 

 in contrast to the specimens from the Isle of Pines. The latter speci- 

 mens have leaves up to about 7 cm. long and 2.5 cm. wide, acute or 

 even acuminate at the base, while the petiole is comparatively slender. 

 Florida plants referable to Lindau's C. Curtissii are, in fact, very 

 closely related to the specimens from the Isle of Pines, as to leaf 



characters.
