CULTURE. Most of this group do very well under almost all average conditions. Their root systems 
are vigorous and if the plants are not too persistently overwatered they give a good account of 
themselves. More loam may be used in the soil mixtures for the stronger growing genera such as 
Lemaireocereus, Acanthocereus, Eriocereus, Gymnanthocereus, Monvillia, Nyctocereus, Rathbunia, 
Trichocereus, etc. Where heavier soil is used less water is required and one should see that the soil 
does not become water-loggd or sour. Those plants from very dry regions are best given the lighter 
or more sandy mixtures. A general rule of thumb is. that cacti with a very heavy spine armament 
or those with bright colored spines or white hair or a hard leathery epidermis even thought spine- 
less, are from quite dry regions. There are so many apparent exceptions to rules that one hesitates 
to give the advice that every experienced grower uses every day. However a little experience will 
show that the above information is useful whenever in doubt. Plants from very dry regions like an 
airfilled soil and the simplest way to achieve that is by the liberal use of sand and charcoal. Often 
in, ie wilds, plants may grow in heavy soils but nevertheless in cultivation will thrive in the light 
mixtures. 
In window gardens one must use windows that are available but, if choice may be made, those 
facing south are given first choice. East windows or west windows are almost equally useful and 
very good results may be obtained. North windows may be used but since no direct sunlight enters 
more care must be taken in watering. After the first season north exposures produce few flowers. 
Many plant enthusiasts are building small greenhouses either attached to the house and heated 
from the house plant or separate. Lord G Burnham Co., of Des Plaines, IIl., have a full line of such 
greenhouses which may be purchased knocked down and easily re-erected. 
ARTHROCEREUS 
A rare and odd genus of small cerei from Brazil and 
Argentina. The type species has very short joints from 
which the genus received its name which means ‘‘joint- 
ed Cereus.’ The later additions are not nearly so multi- 
jointed. In fact if Spegazzini’s Echinopsis mirabilis is 
placed here it is definitely single jointed. Flowers noc- 
turnal, white with very long slender tube, the stigma 
never exserted, stamens in a ring at the throat mouth, 
adnate to the tube.

AZUREOCEREUS 
A new genus recently described by Akers & 
Johnson. The type species was found in the 
valley of the Montaro River, Central Peru. A 
tall tree-like plant with few, strict branches 
and bright blue epidermis. Many rounded, low 
ribs; areoles large, felted; radial spines straight, 
centrals bent-deflexed, long. Flowers nocturnal, 
white with large, imbricated, laciniate scales on 
tube and ovary. Recently a second species has 
been sent me from southern Peru.

OLD MAN CACTUS 
Cephalocereus senilis 
The long, snowy-white hair of this venerable cactus 
makes it one of the most sought after. No collection 
should be without it. In Mexico it is becoming more 
and more scarce as the small plants have been ruthlessly 
dug up and the old plants chopped down to get the 
seeds. The Mexican government has recently passed laws 
to regulate this. Likes a sandy, well drained soil and 
a light or sunny position, very moderate watering.

CEPHALOCEREUS 
A large genus redefined by Britton G Rose 
to include Pilocereus. There are good grounds 
for making a separation as the plants are quite 
diverse, particularly in the way the flowers 
and fruits appear on the plants. In C. senilis 
there is a definite psuedocephalium near the 
top furnished with bristles and dense, tawny 
wool in which the flowers are more or less 
hidden. Some species produce a mass of silky- 
white wool but with visible fruits and others 
with less hair down to none at all. Several 
new genera have been proposed. The plants 
vary greatly in appearance some being very 
white haired, others have blue stems, others 
have little or no hair.. Many are tree-like some 
to 30’, others are much smaller to 3’ or 4’, one 
is procumbent. While our collection has over 
35 species only a few can be offered.

SNOWBALL CACTUS 
One of the scarcest and choicest of the Old Man 
Cacti. The fine, silky-white hair entirely clothes 
the young plants so that they appear as tufts of 
white cotton. Psuedoespostoa melanostele grows near 
Lima, Peru. Grows easily liking a quite sandy 
soil, very moderate waterings and a light or sunny 
position Some varieties have long yellow spines.
