grows especially in the famous gorge of the Yumury or Yumuri 

 River (Rugel 145). Mr. Schulz (loc. cit. 170) erroneously spells 

 this "Tomory," while Mr. A. H. Moore* also has it wrong as 

 "Sumuri." This gorge is one of the scenic attractions of the 

 northern coast of Cuba; the handwriting of Rugel's labels is 

 somewhat difficult to decipher. In Pinar del Rio it inhabits 

 limestone rocks at San Diego de los Bafios {Britton, Earle & 

 Gager 6674); C. Wright's specimen j8i was collected in Oriente; 

 the locality of the type specimen is doubtfully cited as Havana. 



21. NOTES ON TWO JAMAICA PLANTS 



Ampelocissus Alexandri Urban, Symb. Ant. 6: 15. 1909 



To the description may be added "berry depressed-globose, 

 black, shining, 1.5 cm. in diameter, the pulp watery; seeds 2 or 3, 

 depressed-obovoid, slightly rugose, rather deeply and broadly 

 grooved, 5 mm. long, 4 mm. wide." 



Wooded hillside, Union Hill near Moneague, St. Ann's, 

 Jamaica, at 500 meters altitude, Britton & Rollick 2767; this 

 station is within a few miles of the type locality at Mount Diablo. 



Tabernaemontana discolor Sw. Prodr. 52. 1788 

 Tabernaemontana ochroleuca Urban, Symb. Ant. 6: 34. 1909. 



An examination of the type specimen of Swartz' species in 

 the herbarium of the British Museum of Natural History estab- 

 lishes the identity of these species. 



22. THE GENUS GINORIA IN CUBA 



GlNORIA AMERICANA Jacq. 



As intimated by Koehne (Bot. Jahrb. 3: 349) this species 

 may sometimes bear spines, as observed by me on plants in the 

 palm barren at Santa Clara, in March, 1910 (Britton & Wilson 

 60Q3). This shrub grows along brooks and streams, attaining a 

 height of 2.5 meters, at lower elevations in all provinces of Cuba, 

 ascending to 160 meters in Oriente.
