SELECT PLANTS. 
Eucalyptus diversicolor, F. v. Mueller. 
Furnishes good timber for ship and boat-planks, particularly for 
masts, likewise for wheels. Eich soil serves this and other rapid- 
growing species best, although they live in inferior soil. 
Eucalyptus gomphocephala, Cand. 
Attains a height of 120 feet, the clear trunk up to 50 feet long. 
All the Eucalypts are valuable for the production of tar, pitch, 
acetic acid, potash and various dye- substances. 
Eucalyptus marginata, Smith. 
Instances are on record of the stem having attained a girth of 60 
feet at 6 feet from the ground through the formation of buttresses. 
Eugenia myrtifolia, Sims. 
East Australia. A handsome bush with palatable fruits. 
Fagopyrum cymosum, Meissner. 
This and some allied species are utilized for obtaining a blue dye ; 
they also serve for spinach. 
Fraxinus Chinensis, Roxburgh. 
It is this Ash on which a peculiar wax is produced by Coccus Pela, 
perhaps also on some species of Ligustrum. About 40,000Sbs. are 
exported annually according to Mr. Bernardini. F. ornus is well 
adapted for a promenade-tree, and is earlier in foliage than F. 
excelsior, F. Americana and most other Ashtrees. 
Hibiscus cannabinus, Linne. 
Stems up to 12 feet high, without ramification, if closely sown. 
Rich soil on the Nile has yielded over 30001bs. of clear fibre in one 
harvest. The bearing strength is often found to be more than 
of the Sunn-fibre. 
Lupinus arboreus, Sims.* 
South America. This and another somewhat shrubby species, 
namely L. albifiorus (Bentham), of California, have been used 
there for the reclamation of sand, on account of their long tap 
roots, the latter having been traced to depths of 25 feet, while the 
stems were only 3 feet high. The germination is easy and the 
growth rapid on the sand-downs. For aiding the young Lupins 
for the first two months, to get hold of the sand, barley is sown 
with them, as the latter sprouts in a few days and holds the sand 
in the second week ; the Lupin subsequently covers the sand with 
a dense vegetation in less than a year.
