SELECT PLANTS. 
Rheum officinale, Baillon. 
Western China and Eastern Thibet on the high tableland. It 
furnishes the most of the true Turkey Rhubarb, not merely from 
the root, but also from the woody stem. Suited for our Alps. 
Rubus geoides, Smith. 
Falkland Islands, Fuegia, Patagonia and Cliiloe. A herbaceous 
kind of raspberry-plant with greenish-yellow fruits, resembling 
the Cloudberry, and of a very agreeable taste. Pest adapted for 
our Alps. 
Rubus rosifolius, Smith. 
Tropical and sub-tropical regions of Africa and Asia, also through- 
out the literal forests of East- Australia. This shrub bears in 
woody regions an abundance of fruits of large size, and these early 
and long in the season. 
Rubus rugosus, Smith. 
South- Asia. The fruit, which ripens here all the year round, is 
nearly twice the size of the ordinary blackberry. 
Salix alba, Linne. 
With other large Willows and Poplars one of the best scavengers 
for back yards, where drainage cannot readily be applied ; highly 
valuable also for forming lines along narrow watercourses or 
valleys in forests, to stay bush-fires. The charcoal excellent for 
gunpowder. The wood in demand for matches. 
Secale creticum, Linne. 
Though probably only a variety of 8. cereale, L., it deserves 
specially to be mentioned as furnishing a bread of peculiar taste. 
Sequoia sempervirens, Endl. 
Furnishes the red deal of California. Measurements up to 360 
feet are on record. Its growth is about 32 feet in 16 years. Often 
found on metamorphic sandstone. 
Sequoia Wellingtonia, Seemann. 
Traditional accounts seem to have overrated the height of the 
Mammoth-tree. In the Calaveras grove two of the largest trees, 
which may have been the tallest of all, were destroyed ; the two 
highest now existing there are respectively 325 and 319 feet high, 
with a circumference of 45 and 40 feet at 6 feet from the ground. 
At the Mariposa-grove the highest really measured trees are 272, 
270 and 260 feet high, but one of these has the enormous circum-
