WHITE TORCH CACTUS 
Popular, beautiful and exceedingly easy to grow Tri- 
chocereus Spachianus is a fine plant for the window 
garden. The large, snow-white blossoms are borne near 
the tops of the stems. Plants branch freely from the 
base forming nice colonies. Will stand 10° above zero 
when dormant. Nice 6” - 8” — 50c. 25

CORRYOCACTUS 
The known species are Peruvian with per- 
haps some in Bolivia. The genus is not well un- 
derstood and it is hard technically to separate 
from Erdisia though visually they are easily 
identifiable. They extend north from Arequipa 
and Mollendo, where the described plants are 
found, at least to Chala and | saw them as 
high as 12,000’. Plants columnar to 6’, stiff, 
erect, strongly ribbed, spiny. Flowers diurnal 
with very short tube and broad, open throat, 
perianth yellow or orange; filaments stiff, 
much shorter than petals, numerous; style short 
with numerous stigma lobes; scales on tube 
small, subtending large areoles conspicuous 
with brown or black wool. Fruit globular, 
juicy, much spined.

DAYAM’S TREE CACTUS 
One of the best flowering and fruiting kinds. Cereus 
Dayamii (the plants in cultivation are probably hy- 
brids) is a stout, thick stemmed species bearing long- 
tubed flowers with reddish outer perianth segments

CEREUS 
A large genus mostly found in South Amer- 
ica though some extend to the islands of the 
Carribean. The plants are usually tree-like and 
branched though some are low or prostrate. 
The tree-like forms have a stout trunk. Hum- 
boldt in his Travels speaks of a cylindric cactus 
(probably Cereus) near Maniquarez (Venezu- 
ela) with a trunk 4’ 9” in circumference and 
plants 30’ - 40’ tall. The flowers are very dis- 
tinct, long-funnelform, white or pink nocturn- 
al, with almost naked tube, the perianth fall- 
ing away from the ovary as the petals wilt 
leaving only the long style attached to the 
fruit. Fruit large, fleshy, smooth and spineless, 
red or yellow with white, crystalline, sweet 
pulp. The flowers of C. Huntingtonianus are 
pink, the fruit with red pulp inclined to be 
dry. The species are all desirable and in sub- 
tropical and tropical regions have been widely 
planted for their ornamental effect and their 
fruit. They like a rich, porous soil and a sunny 
position. In winter they may be stored in a 
light, frost-free basement or attic. They stand 
considerable cold and most will survive 20° 
when dormant.

CHAMAECEREUS 
A small Argentine genus placed near Rebutia 
and Lobivia differing from Rebutia by bearing 
the areoles on ridges and from both in its 
creeping, prostrate habit. While it hybridizes 
freely with Lobivia it is not too close. The 
small, much branched plants of the common 
species are found in almost all collections. 
They grow under almost any conditions. To 
flower well they like a long winter rest. When 
dormant they will stand temperatures below 
20° without damage.

ERDISIA 
An interesting genus from Peru and Chile 
and probably also Bolivia. Those from the At- 
lantic drainage of the Andes are quite different 
in aspect from those of the western slopes. 
Erdisia Meyenii from Arequipa is a short, fat 
stemmed plant forming colonies connected be- 
low the ground. The eastern species are slender 
stemmed either upright or creeping, sometimes 
with quite large rootstalks. The photograph in 
Britton G&G Rose is probably not that of E. 
squarrosa nor is it sure the plants around Cuzco 
are E. squarrosa. | did not see plants from the 
type locality Tarma but collected plants at 
Ollantaytambo, another species at Limitambo 
at a lower elevation, another species at Huanu- 
co with very fine spines and one other at 
Huancayo which somewhat resembled the one

BROWNINGIA CANDELARIS 
One of the strangest appearing plants in nature. It 
grows on the very arid, barren deserts about Arequipa, 
Peru at 7,000’-9,000’. In the background may be seen 
the snow-capped cone of El Misti volcano. The cactus 
has a columnar, very heavily ‘armed trunk which 
branches into a head of slim, almost spineless branches 
which in age become lax and contorted. Growing as 
isolated specimens in company with Arequipa, Tricho- 
cereus, Binghamia, Corryocactus, Erdisia, Tephrocactus 
and Opuntia. No plants available. Photo by John Akers. 
at Cuzco and Backeberg’s E. maxima. The 
genus is close to Corryocactus and needs more 
critical study. Flowers red or orange red.

ERIOCEREUS 
Britton G Rose treated Eriocereus as a sub- 
genus of Harrisia but there appears good 
grounds for separating them. They are night 
flowering the blossoms large, white or pink 
the fruits red. They are scandent or climbing 
or procumbent often with almost tuberous main 
roots. They are strong growers and like a good 
sized pot and rich porous soil. Plenty of water 
during the growing season. They will stand 
temperatures of at least 20°.
