Helicia (Rhopala) represents the family of Protectees. 



Stilaginece. — The affinity of this order with Euphorbiaceae 

 is very strong, so much so, that it appears to me that no 

 truly distinctive mark exists except perhaps the dehiscence 

 of the fruit. 



Several species exist about Mergui. The fruit is not 

 always drupaceous. 



Gymnobotrys, Wallich, which I refer to Stilaginese, abounds 

 in milky juice. 



Myrsinecc. — Several species of Ardisia and one of Samara* 

 represent this order, in which the presence of pellucid glands 

 in the leaves is by no means an uncommon character. 



Two species of Lobeliacece and one of Codonopsis of Cam- 

 panulacece occur ; with regard to this last genus, it appears 

 to me questionable whether the tube of the corolla is not 

 united to the ovarium as in Barclaya : in this view of the case, 

 the involucrum of M. Alphonse DeCandolle will be referable 

 to the calyx. 



Stylidece. — Two very distinct species, neither of which 

 appear to have an irritable column, are found about Mergui. 

 A third species exists at Moulmein.
