SENECIO. 
S. angulatus was introduced by seeds sent by Prof. MacOwan 
in February, 1875. It is now widely spread along the Riviera, 
covering in autumn and winter the banks and walls with a rich 
mass of golden yellow flowers. 
S. Barba-Johannis and S. Prainianus were procured from Mr. 
Willy Miller, Nocera, in 1909; both were originally introduced by 
Cay. C. Sprenger from the neighbourhood of Vera Cruz. Of S. 
deltoideus seeds were sent by Mr. D. Hanbury in November, 
1870, probably from Prof. MacOwan. This is now semi-wild in 
some parts of the garden, where it climbs over shrubs and trees and 
forms a great mass of fresh green. The flowers are insignificant. 
S. mkanoides is a more decorative plant. It has run wild in 
some places, for instance at Bordighera, where it climbs over 
hedges. 
_ S. macroglossus is a much finer climber, with showy flowers. 
It was received from Kew in February, 1875. 
S. hadiensis was received from Cay. C. Sprenger in 1901; its 
introduction is due to Prof. Schweinfurth. 
S. grandifolius and S. Petatites are Mexican shrubs. with 
ornamental foliage. S. Praimianus is much related to the last 
species, but it differs from it by its large drooping panicles, larger 
flower heads, and almost glabrous leaves. S. precox is another 
Mexican, almost succulent, species, collected by Mr. C. A. Purpus 
in 1905. The species had previously been in the garden; and 
flowered in 1891 (see plate V.). S. longzfolius is a half succulent 
shrub from the Cape. Seeds were received in June, 1872, probably 
from Prof. MacOwan. It is almost subspéntaneous in the garden. 
S. gunceus and S. scaposus are succulents. 
SEQUOIA. 
Of S. gigantea, the ‘‘ Big Tree”’ of California, we have only a 
young plant. 8S. sempervirens, the evergreen “Californian Red- 
wood,” is not quite so fine with us as it can be seen in 8.W. 
Ireland and on the Italian Lakes. Our tree is about 22 m. high, 
with a circumference of 3 m. at the base.” 
* Prof. Willis Linn Jepson, in his book The Silva of California, gives an 
excellent account of both species, illustrated by many fine photos, their 
geographical areas, and economic value. According to him S. sempervirens 
reaches 100-340 feet in height. It is an inhabitant of the humid coast region 
from the south-west corner of- Oregon to Montery County, a narrow strip 
450 miles long and 20 miles wide, reaching an altitude of 3000 feet. ‘‘ This 
Redwood belt is as distinctly marked by its physical and climatic characteristics 
as by its presence of Redwood trees. It is distinguished as a region of high 
rainfall in the rainy season, of prevailing fogs in the dry season, and of 
slight change of temperature during each day and during the year.” S. gigantea 
is said to become 150-325 feet high. ‘‘ It inhabits the western slope of the Sierra 
Nevada from Placer Corner to Tulare County, a longitudinal range of 250 miles. 
The southern groves reach an altitude of 7500 feet above the sea. It is a 
region where the average rainfall is 45-60 inches, where the snow becomes two 
to ten feet deep, and lies on the ground three to six months! The average age 
of adult trees is 400-1500 years. A few trees show as high as 2200-2300 rings.”
