E. multicostatus SB1147 Los Imagines, Coahuila, Mexico
It is very characteristic with multiple, very
tight, thin and wavy ribs.
multicostatum is one of the most variable Echinofossulocactus
differing in spination, body shape and number of ribs.
Stem: Solitary, globose, vivid green with a flat tops 8-15cm wide and up
to 7-12 cm tall, typically with 50 to 100 (150) multiple, very tight,
thin, wavy ribs.
Areoles: There are only 2 or 3 areoles in each rib,
witch are covered with white felt in young plants
Spines: 6 to 9(-12)
radial spines, the upper ones are longer whit a central stout and flat
erected spine, while the lower ones are shorter and point downwards. The
spines are different lengths.
Flowers: The blooms are white with a violet to purple midvien in
Typically it has a variable
number of ribs (typically about 50 to 100 ribs),
plant whit up to 150 (or more) ribs has been reported.
Cultivation: Small growing and easy to to care and
flower. Because of it’s small size makes a great potted plant specimen,
great for beginning collectors. It needs regular cacti soil with good
drainage. Propagation: Seeds (usually) or by the shoots of adult plants
(if available). Exposure: need some direct sun but is tolerant and
prefers light shade during the hot Summer months, allow to dry between
watering. Watering should be curtailed during the winter months. Frost
Tolerance -5°C if kept dry.
seeds, remembering that
seedlings dislike strong
dry conditions and need to be
repotted frequently. Eventually, as they become mature, they attain a
maximum size of 8-10 cm (20) cm. However, old plants become
senile and have
a tendency to succumb to
disease and a weak
root system. At this
as is well known, they
suddenly. So, after they reach 10 cm in diameter grow them slowly, and
adopt a new repotting period, using intervals of every 2 - 3 years.
Additionally grow them under drier conditions or with stronger sunlight.

The plant of this species
found in cultivation are quite variable, and the dissimilarity
among seedlings spination and ribs shape may be considerable.
