material, will haxe to be considered at a later date, when more complete 

 specimens are available. PhrygUanlhus, included by Bentham in Lor- 

 anthus, but distinguished primarily by its versatile anthers, is here 

 retained as a genus, and is represented in the Archipelago by a single 

 species, which must be considered as an Australian type. Cleistoloran- 

 thus^ remarkable for its cylindric corolla-tube entirely closed at the apex 

 by the inward projecting and connate basal portions of the lobes, and by 

 its very short, spreading, irregularly toothed, e-xternal portions of the 

 lobes which are broader than long, is described as a new genus. Viscum 

 is represented by four species, all of wide distribution; Notothixos by 

 three endemic species, and Ginalloa by a single endemic species. The 

 table below gives some idea of the distribution in this part of the world 

 of the genera and species, the latter being much more strongly developed 

 in the Malay region than to the north and south. Arccuthohium, with 

 one species in the Himalayan region, and Nuytsia and Atbinsonia (Gaia- 

 dendron) with one species each in Australia, are not included in the table.
