naturally receive about 12 inches of rainfall annually. 
Planted in the open in drier climates they will 3 hift 
for themselves. In moist climates out of door 3 , plant 
on an elevation of light soil so that rotting will not 
occur thru poor drainage. 
The kinds of cacti naturally fall into two groups. The 
Ball Cacti do not branch and never have Leaves. They 
consist of a dome shaped stem, and all are smaller than 
6 inches high. The rest of our cacti are in the genus 
Opuntia. These have small leaves on the new growth that 
fall off about the time the spines start growing. The 
Opuntias get larger and are either tree-Like in growth 
or else have flat oval shaped stem (prickly Pear type 
of growth).

Ka millaria ( Coryphanth a ) viv ipara i3 quite dome shaped 
growing over 3 inches in diameter and the same in height. 
The fLowers are an inch in diameter and bright purple. 
The green spineless fruit ha3 a very attractive fruity 
flavor. This species is easily grown as it really grow3 
better in a climate that is more moist’ than ours. 
Technically the plant is covered with' tubercules (nipple¬ 
like) - by 5/l6 inches, grooved on the upper side. On 
the tip are 12-20 white spines with brown tips. Four 
central spines are longer and heavier and quite brovm. 
Flowers arise from between the tubercules at the top of 
the plant. Seeds are brown and fiat. 
E chinocereus viridi florus grows 3 inches high by 2 in 
diameter. The spines are borne on ridges. The yellow • .. 
flowers appear profusely in June and remain open several 
days. This is an excellent cactus that grows readily 
under a wide range of conditions from hot prairies to 
7,000 feet altitude. Technically the spines are borne on 
slight tubercules arranged in about. 13 vartical or spiral 
ridges. The radial spines are 12-18 of variable length 
and color, most being white with the longer ones red 
tipped. There is usualLy one stout red central spines
