naturally receive about 12 inches of ra.infall annually. 
Planted in the open in drier climates they mil shift 
for themselves* In moist climates out of doors, plant 
on an elevation 'of light soil 3,0 that rotting' will not 
occur thru poor drainage. 
The kinds of cacti naturally fall into tv/o groups.^ The 
Bali 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 yiqij gro^ivth that 
fall off about the time the spines start grov;ing. The 
Opuntias get larger and are either tree-like in gro-wrth 
or else have flat oval shaped stem (Prickly Pear type 
of growth). . . , ,

P^illa ria (C oryph antha ) vivip ara is quite dome shaped 
grov;ing over 3 , inches in diameter and the same in height* 
The fio^vers are an inch in diameter and bright purple. 
The green spineless fruit has a very attractive fruity 
flavor. This species is easily grown as it really grows 
better in a climate that is more moist than ours. 
Technically the plant is cov-^red with tubercul.'s (nipple¬ 
like) - , by 5/L5 inches, grooved on the upper side* On 
the tip are 12-20 white spinas f-ath .broim tips. Four 
central spines are longer and heavier and quite brown. 
Flowers arise from between the tuborcules at the top of 
the plant. Seeds are bro\m and fiat. 
F chinccere us 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. Itiis 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 vertical or spiral 
ridges. The radial spines are 12-18 of variable length 
and color,most "being white vath the longer ones-red 
+J.pped. There is usually one stout red central spines 
''?.ch may be white or absent. The fruit is oval,spiny.
