material, will have to be considered at a later date, when more complete 
specimens are available. Phrygilanthus, 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, external 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 Mala} 1 region than to the north and south. Arceuthohium, with 
one species in the Himalayan region, and Nuytsia and Athinsonia ( Gaia - 
dendron) with one species each in Australia, are not included in the table.
