The name of this new species is published with the 

 permission of Mr. C. B. Clarke, to whom I am indebted for 

 the diagnosis in Latin. The description, in English, has 

 been made by me from my Mauritius specimens, which are 

 in flower, but not in fruit. 



Mr. C. B. Clarke, in a letter, dated Kew, 15th March 

 1895, writes, with reference to 0. costularioides : "It has 

 happened (and it is an accident that has frequently happened 

 to me) that while I never saw the plant till you sent it me, 

 I have since found it several times in old herbaria that 

 have come to my hand, both from Bourbon and Mauritius ; 

 it is Boivin n. 998, Goudot n. 1833, both from Bourbon." 



In Mauritius I observed this species growing in a forest 

 swamp, 1920 feet above sea-level, at the Mare aux Vacoas, 

 on 28th September 1888 ; and in a forest, 940 feet above 

 sea-level, at Le Grand Fond, Flacq, on l7th June 1890.
