Summary
Rob Bregman
In his editorial, Jan Jaap de Morree tells us a little bit about his visit to Surinam
where he met Melocactus specialist Geert Eerkens.
In the series on the old ‘Verkade’ books, Theo Heijnsdijk deals with Pelecyphora
aselliformis. Some nice historial pictures are included. Despite the fact that the plant
is placed in the CITES 1 category, it is not threatened in nature.
Bertus Spee presents another 4 interesting succulents with brief descriptions
and tips for succesful cultivation, viz. Saxifraga cymbalaria, Haemanthus albiflos,
Euphorbia horrida and Maihuenia poepigii.
Herbert Thiele went to the southwestern USA to look for micropuntias. He found
M. pulchella and M. gracilicylindrica in their natural habitats. In winter these plants
are covered by (up to 2 meters of) snow; they can withstand severe frosts.
Ben Zonneveld reports about his crossing experiments with Jovibarba heuffelii
(Crassulaceae). He succeeded in crossing the pubescent green form with the glabrous
red form, resulting in plants with red pubescent leaves.
Arjen de Boer interviewed Harald Grieb, an US official at the US-Mexican border.
His task is to control people who are trying to import CITES 1 plants and seeds
into the US.
Bart Hensel visited the habitats of Copiapoa krainziana and C. scopulina in the
Quebrada San Ramon, in northern Chile. He concluded that both species are in
fact conspecific, because the two forms are not clearly separated, both geographically
and morphologically. At lower altitudes the (white) krainziana form is dominant,
at higher levels it is the (dark) scopulina form.
Norbert Gerloff reports about Brasilicactus haselbergii. The natural habitats appear
to have suffered severely from illegal collecting. The related B. graessneri, with
green or yellow flowers, is also discussed.
Jan Jaap de Morree tried to turn a Kedrostis capensis into a bonsai but the plant
refused to be treated that way.
An impression of the botanic garden of Singapore is given by Richard de Bruijn.
Bertus Spee found Echeveria cante in the Sierra Chapultepec, Mexico. Back
home, the collected seeds germinated very well.
Madagascar lover Peter van Dongen deals with some endemic pachypodiums.
A new book by Steven Hammer on a group of mesembs (Titanopsis group) is reviewed
by Jan Jaap de Morree.
Finally, Wolter ten Hoeve reviews the contents of other journals on succulent
plants.
