Identifying more cactus
Please could you help identifying these cacti for me please. (Ignore the numbers on them).
I'm not really a cactus expert, but the website CactiGuide.com helps with ID. There are so many species and some appear similar. Flowers can help to identify a specific species.
Both appear to be from the genus Echinocereus (hedgehog)
#5 is possibly E. coccineus.
