Order LIII. HALORAGE,® 
King, l.c. 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. By. 
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. RHIZOPHORACE/E 
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, 1- 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.
