fruit. In the cooler southern regions the tree attains 
considerable dimensions. The wood tough and elas- 
tic—used for boat-building (Dr. Philippi). The fruit 
of the allied Brabejum stellatifolium can only be util- 
ized with caution in a roasted state as an article of 
diet, because it is noxious or even absolutely poison- 
ous in a raw state. 
Guilandina Bonduc, Linné. — Widely dispersed 
through the inter-tropical regions of both hemispheres 
with G. Bonducella, L. Both would be well adapted 
for hedges in the warmer parts of our colony. 
Gunnera Chilensis, Lamarck.—From Caracas to Pat- 
agonia, chiefly on cliffs. A most impressive plant for 
scenic groups in gardens. Darwin measured leaves 
8 feet broad and 24 feet in circumference. The acid- 
ulous leaf-stalks serve as a vegetable ; the thick roots 
are used for tanning and dyeing. G. macrophylla, 
Blume, is a native of Java and Sumatra, where it 
occurs on mountains, up to 6,000 feet. : 
Harpullia Hillii, F. v. Mueller.—The Tulip - wood 
of Queensland. One of the most valuable of the nu- 
merous kinds of trees indigenous there for select cab- 
inet-work. 
Heleocharis tuberosa, Roemer and Schultes.—Chi- 
na, where it is called Matai, or Petsi. This rush can 
be subjected to regular cultivation in ponds for the 
sake of its edible, wholesome tubers. H. plantaginea 
and H. fistulosa, of India, and our own native H. 
sphacelata are allied plants. 
Helichrysum lucidum, Henckel. (H. bracteatum, 
Willdenow. )—Throughout the greater part of Austra-

would be remunerative to supply its everlasting flow-
