Echinocereus coccineus subsp. paucispinus spine epidermis (surface) (x500)

Hello,
my name is Wolfgang Blum I'm an active founding member and Vice Chairman of the Echinocereus Study Group of the
German Cactus Society and I' ve written the book “Echinocereus” with Michael Lange, Werner Rischer
& Jürgen Rutow. The book about this fine Genus Echinocereus (Cactaceae) was published in 1998.

I' ve written the books:
Echinocereus reichenbachii-fitchii-complex (2004)
Echinocereus Section Wilcoxia (2008 )
Echinocereus parkeri group (2011)
Echinocereus viridiflorus complex (2012)
Echinocereus adustus group (2014)
Echinocereus triglochidiatus group (2015)
Echinocereus coccineus group (2017)

at present we are working again on the realization of our book over the Echinocereus acifer group (2018).

Booklets:
Echinocereus pulchellus and subspecies 2006
Echinocereus fendleri and subspecies 2014
Echinocereus dasyacanthus and subspecies 2015
Echinocereus pectinatus and subspecies 2016

So far I have under the genus Echinocereus:

26 descriptions of ranks (Section, Series, Subseries, Species, Subspecies and Cultivar),
52 combinations of ranks (Subgenus, Series, Subseries, Species, Subspecies and Forma)
released.
