Ton Pullen opens the June issue, fantasising
what the world will look like in
10-20-30 years time. He thinks that there
will be a greater interest to grow botanical
species and cultivars and hopes that DNA
analysis will bring some clarity to the relationships
of species, but fears that only the
nature of the arguments will change.

The search for Pachypodium species in
Madagascar concludes with a number of
comments on their availability and cultivation
tips for the genus.

The genus Echinocereus enjoys special
interest in this issue. The first of a series
of articles entitled ‘From bud to flower’ by
Albert Pilot is dedicated to Echinocereus
subinermis.

Wim Alsemgeest explains how to graft
very young seedlings on Echinopsis hybrids.
He is extremely enthusiastic about
the results that can be achieved.

Mammillaria does not want to fall behind
Echinocereus and also has two articles
dedicated to it. The first, by Ton
Pullen, features M. sphaerica.

And on to the second Echinocereus article, this
time by Robert Mayer. Species can demonstrate
a range of variability and Robert confirms this
by looking at the different forms of spination
found in Echinocereus viridiflorus var. davisii.

Jos Huizer is still talking about his trip to Arizona
and New Mexico. You may already have
guessed that he too is a fan of the genus Echinocereus.

goes by the title ‘Around California’, but who
can limit himself to just one State? Not Theo.

the Agave has reached the Caribian, producing
yet another well documented article.
