ovary having been described by Don as unaocular with parietal 

 placentae, contrary to the more accurate characters given by Euias 

 and Pavon, and' by Bonpland. 



The geographical range of the species is extensive, — along the 

 whole length of the Andes of South America, from New Grenada 

 to the Straits of Magellan ; and, as might be expected, there arQ 

 considerable variations in the foliage, although much less than ixx 

 some of our own shrubs, such, for instance, as our common Holly. 

 1 he connecting line of the petioles often shows on each side two 

 mmute teeth or protuberances, from whence two prominent lines 

 are more or less decurrent along the young branches, disappearing 

 entirely on the older ones. In the smaU-leaved specimens gathered 

 at great elevations within or near the tropics these lines are par- 

 ticxilarly prominent, and characterize the I>. acntangula of Dunal. 

 J- he southern specimens have usually a luxuriant foliage and 

 broader and more ciliate lobes to the calyx, constituting the D^ 

 ■aooJceri^ Dun. Specimens similar to these, but with unusually 

 large leaves and more numerous teeth, were originally selected by 

 ■Kuiz and Pavon to figure as their D. spinosa; and when Bonpland 

 had only before him the commoner Columbian form with few 

 large teeth to the leaves and narrow scarcely ciliate lobes to the 

 calyx, he did not venture to identify them as the species figured 

 m the * Flora Peruviana,' and therefore published them as a 

 <iistinct one under the name of Z>. splendens. But all these trifling 

 differences are so variously combined in the numerous specimens 

 before me, that I cannot but regard them as mere variations of 

 one species which will retain the older name of B. spinosa.

 several other Loganiaceous genera, but it forms in the whole
