There is no order with which I can satisfactorily point out 

 that this genus has any affinity. In many respects the leaves 

 resemble those of some Loasece, and Turneracem ; but the 

 perianth being perfectly free from the ovary removes it from 

 the former, and with the latter there is little resemblance. 

 The ovules being in pairs forbid its being placed in Urticece, 

 with which Mr Harvey is disposed to ally it, but it may be 

 conveniently placed in that neighboHrhood until the male 

 flowers and fruit be known. 



Trichilia Ekehergia^ E. M., is a genuine species of Eke- 

 bergia, as restricted by Adr. de Jussieu in his valuable 

 memoir on the Meliacece. It chiefly differs from my speci- 

 mens of JEkebergia capensis, Sparm. (or Trichilia capensis, 

 Pers.,) by the larger size of the foliage and panicles,- but 

 that may be the effect of accident. In T. capensis, which is 

 in Zeyher's Uitenhage collection, No. 559, the ultimate 

 branches are almost destitute of leaves except at the apex, 

 but are covered with numerous tubercles from which the 

 previous leaves seem to have fallen off.
