A REVISION OF THE GENUS HAMELIA 213 



Nearly related to the Mexican H. versicolor, but distinguished 

 especially by the shape of the corolla-tube and the size and shape 

 of the fruit.

This species is notable for its relatively large globose berries, 

 about 8 mm. in diameter. 



A curious inaccuracy appears in the original description of 

 this species, the number of stamens being given as " saepius 7." 

 The pentamerous condition of the androecium is so constant 

 throughout the genus that the presence of a larger number of 

 stamens in any flower under examination would reasonably arouse 

 some suspicion of abnormality. I have, however, dissected several 

 flowers of the type-plant itself {Palmer, 125), but in no case was 

 the number of stamens other than 5 ; and this applies also to the 

 other specimens examined.

This species seems to have affinities with the Mexican H. nodosa 

 Mart. & Gal., but is distinct in the relative smallness of its leaves 

 and flowers, the arrangement of the inflorescences, and the 

 character of the seed.
