Got these cactifrom a friend in South Texas who had to remove quite a few to make place for a wall. The large red one has a central hook spine and all others are straight. Any help greatly appreciated.
I don't know, what species are they exactly... :( BUT I asked an expert on my favorite cacti-site... :) Here: http://www.kaktuszgyujtok.hu/index.php?page=&subpage=/nml/forum.nml&forumtid=35 -Echinocereus berlandieri -Echinocereus triglochidatus -Ferocactus hamatacanthus
-Echinocereus berlandieri, or E. enneacanthus! -Echinocereus triglochidatus, or E. coccineus ssp. paucispinus! -Ferocactus hamatacanthus
