Dr. Shafer's notes show this to be a shrub about 1.3 m. high, 

 with white flowers. 



25. Rondeletia Rugelii Urban, Symb. Ant. 7: 397. 1912 



Rondeletia Poitaei microphylla Griseb. Cat. PL Cub. 128. 1866. 



Type locality : near Matanzas. 



Distribution: Known definitely only from the type locality. 



Rugel's label indicates that this is a shrub growing in rocks. 

 The species is related to the following one. Grisebach considered 

 the plant to be the same as R. Berteriana A. Rich, (not DC), 

 which was collected at La Cabana, Havana. R. Berteriana DC, 

 of Hispaniola, is clearly different. 



26. Rondeletia Combsii Greenm. Trans. Acad. St. Louis 7: 427, 



pi. 34- 1897 



Type locality: Calicita [Santa Clara]. 



Distribution: Hillsides, cliffs and rocky shores, Santa Clara; 

 Havana. Endemic. 



Plants with identical foliage have calyx-lobes ovate or lanceo- 

 late; Dr. Greenman's original description indicates that they 

 may even be linear. A fruiting specimen from Bahia Honda, 

 Pinar del Rio {Wilson 9409), is doubtfully referred to this species. 



27. Rondeletia camarioca C Wright; Sauvalle, Anales. Acad. 



Habana6: 102. 1869 



Type locality: Savannas of Camarioca [Matanzas]. 

 Distribution: Serpentine barrens and savannas, in dry soil, 

 Camaguey; Santa Clara; Matanzas. Endemic.

 long; peduncles solitary in the axils, stout, about as long as the 

 petioles, i-flowered, pubescent; bractlets ovate, acute, 1 mm. long;

 lobes ovate-oblong, obtuse, 1 mm. long.
