THELOCACTUS NIDULANS 
A curious, heavily spined cactus from Mexico. While 
the spines are stiff they are not wicked and peculiarly, 
they shred with age. The ribs are heavily tubercled the 
plant body blue-gray. Flowers large $2

REBUTIA 
A genus of small plants closely allied to Lo- 
bivia with which they differ in being tubercled 
rather than ribbed and in the small globular 
fruits being thin walled, red or yellow instead 
of green. There are many intermediate forms 
which have been assigned to Aylostera and 
Mediolobivia. These groupings help to bring out 
relationships to the student but botanically are 
hard to justify. Plants very easy to grow, very 
floriferous and generally small. Use good, rich, 
well drained soil rather more water than most 
cacti and a light, not too hot or sunny location.

PINE CONE CACTUS 
Encephalocarpus strobiliformis is closely related to 
Ariocarpus differing in the numerous, scale-like, dor- 
sally keeled, incurved, closely imbricated tubercles, on 
the ventral side a tiny areole and few spines. The flower 
is a lively violet-pink in color borne in late spring. 
The plants never seem to attain more than inch and a 
half or so in diameter and grow very slowly. They 
grow very well in coarse sand with some leafmold if 
placed in a sunny, warm position. Water moderately. 
Will stand temperatures as low as 20°. Mature flower- 
ing specimens. Imports.

STROMBOCACTUS 
A small genus of flattened globular plants 
with flattened tubercles arranged in spirals with 
or without spines. Flowers campanulate, white 
or pink with scales on the tube and upper part 
of ovary. Related to Ariocarpus though not too 
closely. These Mexican plants are found in very 
dry regions. They grow very slowly and prefer 
a very porous soil or sand and leafmold. Do 
not overwater. They flower regularly in sum- 
mer.

THELOCACTUS 
An anomalous genus, principally Mexican 
and Texan, that needs a great deal more study 
for the plants generally placed in it are prob- 
ably not too closely related. The plants are 
ribbed or tubercled, often spiraled. Flowering 
tubercles more or less grooved above and flow- 
ers not borne at spine areoles. Plants globose- 
depressed or cylindric; flowers at apex on 
nascent tubercles, diurnal campanulate; scales 
on ovary few, axils naked; fruit dehiscing by 
a basal pore. Belongs in Coryphanthanae and is 
related to Ancistrocactus, Neolloydia etc. Cul- 
ture as for Echinocactus. A very light soil, sun- 
light and moderate waterings. The flowers are 
generally very lovely in pink, yellow, white or 
garnet.

AGAVE CACTUS 
Leuchtenbergia principis 
One of the oddities of the cactus family and with- 
out any close relatives. Instead of ribs it bears long, 
angled tubercles which gives it more the appearance 
of an Agave than a cactus. It is a member of the 
Echinocactanae as it bears its flowers. near the tips of 
the nascent areoles and has a dry, scaly fruit dehiscing 
by a basal pore. Flowers are large, straw-yellow and 
quite fragrant. The tubercles are blue-green the tips 
bearing an areole with papery, yellow, curling ribands. 
Monotypic, give it a porous but rich soil and plenty of 
sun, Hlasy to grow.

ECHINOMASTUS 
This small genus rightfully belongs in Cory- 
phanthanae as Marshall has correctly stated 
though all other authors have placed it with 
Echinocactanae. It bears its flowers at the base 
of the tubercles and not at the spine bearing 
areoles. Not very easy to grow as they come 
from very dry regions. Grow well in sand and 
leafmold with moderate water supply in sum- 
mer. A well lighted, airy position.
