Echinocactus horizonthalonius 
A group picture from collection of the late J. H. Callender, Peterboro, Ont. Canada. 
The three splendid specimen plants shown in the greenhouse picture at up¬ 
per left are Neon ammillaria compressa, Echinccactus grusonii and Ferocactus 
emoryi. 
Echinocactus grusonii—Hidalgo, Mexico. Plants usually single, depressed, 
globose, light green with golden yellow spines. Grow very large, 20-25 inches in 
diameter. Very attractive species, outstanding in any collection. 
Echinocactus horizonthalonius—W. Texas, Northern Mexico. Simple globu¬ 
lar, ribs usually 8; spines very stout. Flowers pink to rose. Needs perfect 
drainage, old lime in its soil and little water. 
In the group picture below the very large clump at the back is Neomammill- 
aria multiceps, allowed to grew many years without being disturbed. 
First plant in the middle row is Echinocereus \iridi lorus widely distributed 
from W. Texas to Wyoming and S. Dakota, variable in habit and spines but 
always green flowered. 
Second plant appears to be Ferocactus lecontei. 
Third an Echinocereus cristate. 
First plant (left) in front row is a several headed plant of Homalocephala 
texensis which has distribution through Northern Mexico, Texas, New Mexico. 
A flattened globular, strongly ribbed, flowers pink, rather large, day blooming, 
last 4-5 days, delicately fragrant. Large red fruit. Grows well and flowers in 
cultivation. Note: Ferocactus macrodiscus is undoubtedly congeneric with this, 
species. 
Second plant is a member of Echinopsis. 
Third is an unusually fine specimen of Echinocereus reichenbachii var. 
caespitosus or the “White Lace” cactus, Texas. A very attractive species with 
large, fragrant pink blooms. 
Cactus intortus—West Indies. Globose to cylindric. Mature plants form 
cephalium on top center, made of white wool and red bristles. Through cephalium 
appear rose flowers and rose colored fruit. It is one of the ‘‘Turks’ Caps”.
