Order LIII. HALORAGEi^ 



King, I.e. 309, gives two species of this order as inhabitants 

 of the region, but the evidence for their occurrence here is so 

 doubtful that I exclude both. They are : — 



Haloragis micrantha R. Br. 



Perak? Scortechini. "No specimens in Scortechini's collec- 

 tions, but a field note from him " (King). 



Not given by King. 



Myriophyllum intermedium DC. 



" Malacca, Griffith, probably on Mt. Ophir." No specimen 

 occurs in Griffith's collections at Kew, nor is it mentioned in the 

 F.B.I. Mt. Ophir is a most improbable locality for this pond- 

 weed. 



Order LIV. RHIZOPHORACEiE 



Tidal mud trees. Leaves opposite stipulate, coriaceous. 

 Flowers in axillary cymes, rather large. Calyx-tube obscure, 

 adnate to ovary ; sepals coriaceous 4 to 14. Petals 4 or more, 

 entire or lacerate. Stamens 8 to many. Ovary inferior, i- to 

 4-celled. Fruit fleshy, more or less conic. Embryo germinating 

 before the fruit falls and emitting a long thick root. Species 

 about 20, tropics. The Mangroves, Bakau of Malays.
