peculiar tendency to sprawl along the ground for a great 
deal of their length before rising. There may be two or 
three heads, but a single crown is usual. This is rather 
dense, with the fronds more upright than usual, their tips 
drooping gracefully. The fronds are 4-10 feet long on 
smooth, softly hairy stalks. The lower part of the stalks, 
as well as the whole axis of young fronds, is thickly 
clothed with long soft dark red hairs. The fronds them- 
selves are three times pinnate, the pinnae 7-16 inches long 
and 2-3 1 inches wide ; the secondary pinnae are 2-3 inches 
long and f inch wide ; the ultimate or tertiary pinnules 
are about 4- inch long, sometimes less, and are divided into 
several small lobes, each of which may bear a sorus. These 
sori arc placed on the margins of the segments enclosed 
in a two-lipped receptacle, the outer lip consisting of a 
recurved lobe of the frond, the inner one comprising the 
indusium proper. 
D. Youngiae. 
This species is apparently rare in Queensland and its 
known distribution is scattered. It has been found on 
Mounts Spurgeon and Bellenden-Ker, between Cairns and 
Herberton, on Fraser Island and at Robert’s Plateau 
(Macpherson Range) which forms part of the southern 
border, and extends into New South Wales. No doubt 
it will later be found in other out-of-the-way localities 
intermediate between those quoted. 
The fronds are very similar to those of the preceding 
species, differing mainly in the much larger indusium. It 
forms only a short trunk 10-12 feet high and is said to be 
fond of wet situations near creeks. 
ANGIOPTERIS. 
A. evecta. Fig. 7. 
This is not a tree-fern in the usual sense, having only 
a short thick trunk (sometimes more than one) and no 
regular crown as for instance in most species of Cyathea. 
The fronds and stalks are extremely large and fleshy, of a 
dark green colour and very spreading habit, one plant 
occupying a considerable area. It inhabits rain-forest and 
has been found as far south as the Blac&all Range, in 
gullies, and on Fraser Island. It occurs in the Carnarvon 
Ranges, but is most abundant in the far northern rain-
