E. robusta, a very handsome tree, with large, dark-green, shining 
leaves. It is particularly attractive when in bud. The buds are a 
delicate cream pink and quite large. The timber of this tree is very 
durable and especially resistant in earth or water. It contains the 
largest percentage of kino yet measured. For ornamental road or 
street planting it is now the most sought of any of the eucalypts. 
H. rostrata, red gum. This tree contains a considerable proportion of 
oil in the foliage and of fine kino in the timber. It is a highly valued 
timber in Australia. It isa good grower and is particularly adapted to 
very hot, dry climates. It also does well in our mild valley climates. 
I have just successfully introduced the tree in Arizona, where a num- 
ber of other eucalypts have failed. It is with us nearly all the time 
eovered with new growth. This is a vivid willow-green in eolor. The 
particularly agreeable odor of the leaves is an additional attraction. 
E. leucoxylon, var. rosea. This tree has two distinct forms—one with 
green foliage and pink flowers and the other with silver-gray foliage 
and pink flowers. Both have a deep-red persistent bark. The silver- 
gray is far the more striking. The timber of this tree is exceedingly 
durable and is stronger than English oak (Laslett). 
We have two other forms of H. leucoxylon here. One has rough red 
bark, green foliage, and white flowers. This is a very shy bloomer, 
while the others are all free flowering. The other form has a white, 
smooth bark, from decortication; green foliage; and, besides, grows 
differently. The first three are stromg, single-stem trees, while the 
last, or white bark one, grows larger, but tends to branch low and 
make several stems. I feel sure that some of these varieties should 
have specific rank. The silver-leafed E. leucoxylon with pink flowers 
is extensively planted for or nament. 
E. polyanthema is also planted for ornament. It has round leaves of 
Silvery blue color. 
LE. fissifolia is extensively ea for its dark-green leaves and mag- 
nificent crimson flowers. Itis to be noted that our seedling L. jfissifolias, 
vary sometimes in flower color, the range being pink, orange, crimson, 
and magenta. 
EH. maculata, var. citriodora, is planted for the delicate fragrance of its 
foliage. The timber of this tree is valuable. 
The most successful of these trees in California are H. corymbosa, 
bloodwood; EH. resinifera, red mahogany; LH. diversicolor, karri; E. calo- 
phylla, South Australian red gum; LH. botryoides, bastard mahogany; 
the searlet-flowered EL. jfissifolia, for ornament only; H. corynocalyx, 
sugar gum, for dry soils; and H. robusta, swamp mahogany, for heavy, 
damp soils and as an ornamental shade tree for streets. 
Reports from the Exotic Nurseries of Seven Oaks, Florida, speak of 
EH. robusta and HE. resinifera as growing the fastest there. It is reason- 
able to presume that this type of foliage would be more favorable to the 
climate of Florida than that of the equally green group, doubtless
