A point of morphological interest, to which I do not, as I write, 

 recollect a parallel amongst allied Dicotyledons, is the occurrence 

 of a hracteole between each flower of the capitulum and the axis. 

 This bracteole is bicarinate with ciliate teels and more or less deeply 

 2.1obed ; possibly made np of two lateral bracteoles connate by their 

 inner margins. 



This plant is quite one of tlie most interesting of the many 

 important additions made by Mr. Baron to the Madagascar Flora. —

Related to E. coriaceum, from which it differs in its smaller more 

 membranous and distinctly acuminate leaves, flowers from the old 

 wood, and anthers considerably shorter than the filaments. Althouffh 

 1 leave the genus m Olacinece, to which order I referred it in the 

 Journal of the Ltnnean Society, viii. 159, it shows considerable affinity 

 ^ith Styrace(B, an order hitherto not detected in Tropical Africa bo 

 far as I know. I have not seen fruit nor seed. — D. Oliver. '
