Halorage;i:. 



Haloragis ceratophylla, Endl. Herberton. I have also seen 

 it on other tropical table lands, where open sandy soil supported 

 a heath-like vegetation. 



Myriophjllum verrucomm, Lindl. In all the almost stagnant 

 fresh water holes of the tropics. 



Ceratophjilum demersum, L., Barron Eiver. 



EiiizonroRE^. 



Illihopliora mucronata, Lam. Mangrove thickets but not the 

 commonest species in the tropics. 



Ceriops Candolleana, Arn. Mangrove thickets, but not the 

 commonest species in the tropics. 



Bruguiera Rheedii, Blume. This is the most common con- 

 stituent of all the mangrove swamps. Its rich, dense foliage 

 redeem the otherwise desolate character of the mud flats of the 

 tropics. B. gymnorrhiza is sometimes mixed with it. 



Terminalia melanocarpa, F. v. Muell ^^Comlretacece). This is 

 a very common tree between Cairns and Cooktown. It grows 

 quite close to the sea and on the coral islets, where the pigeons 

 {Carpopliaga spilorliod) greedily devour its fruits. These are 

 about an -inch long with a very large hard stone, in fact there is 

 scarcely any sarcocarp, so that one wonders how the birds find 

 any nourishment in it. The taste is bitter and unpleasant. T. 

 oblongata, F. v. Muell., is rather common in the Brigalow Scrubs 

 of the tropics. 



Addenda to Malxacem. 



Ahutilon graveolens, "Willd, Mulgrave Eiver, where it forms 

 thickets. A. muticum, Don., Fitzroy Island Hibiscus manehof, L., 

 Mulgrave Eiver.
