used decoratively. The genus is said to be the closest to 
the fossil forms of any representative of the Cycadaceae. 
Dioon spinulosum. Cycadaceae—This plant is a native 
of Mexico, and differs mainly from Dioon edule in having 
the leaflets margined with small, sharp points. 
Encephalartos Altensteinii. Cycadaceae. Kafir bread.— 
A South African plant having a stout trunk and a terminal 
crown of stiff pinnate leaves with spiny apex. The cones 
or fruits of the female plants are soaked in water and eaten 
by the natives of Africa, hence the name Kafir bread. 
Encephalartos caffer. Cycadaceae.—A large plant, native 
of South Africa, with a trunk reaching 18 feet in height 
and 1 foot or more in diameter. The leaves are 4 feet long, 
stiff and recurved, with alternate, twisted leaflets. 
Encephalartos horridus. Cycadaceae—A cycad-like plant 
of South Africa with a short trunk, sometimes woolly. The 
leaves are up to 6 feet long, with lanceolate leaflets which 
have a sharp spine at the apex. 
Encephalartos villosus. Cycadaceae—A South African 
cycad with a thick, short, woolly trunk up to 6 feet. The 
leaves are long, with numerous spiny-toothed leaflets. 
Encephalartos lanuginosus, E. elongatus, and E. Hilde- 
brandtiz, South Africa. 
Eucalyptus globulus. Myrtaceae. Blue-gum.—One of 
the largest trees known, occasionally reaching a height of 
300 feet. It is native of Victoria and Tasmania and there, 
as well as in California and other localities in which it has 
been introduced, makes a remarkably rapid growth. The 
trunk and foliage are grayish blue. The hard wood is em- 
ployed for a great variety of purposes, including mill work, 
ship-building, etc. The fruits are occasionally used for mak- 
ing rosaries and necklaces. The leaves possess febrifugal 
properties, and further, are smoked in the form of cigars 
or cigarettes as a remedy for asthma. Eucalyptus oil, em- 
ployed in medicine against asthma and bronchitis, is dis- 
tilled from the fresh leaves of this and other species of the 
genus. 
Eucalyptus rostrata. Myrtaceae. Red-gum.—A native of 
Italy, reaching 200 feet in height. It thrives in ground 
periodically inundated for a considerable time. The timber 
1s somewhat harder than EZ. globulus and extremely durable, 
and is suitable for fence posts, ties, piles. It is also used
