New aquistions

[kaitlyn25]

I got free cacti on campus and I need help IDing them

[miss_taken_identity]

So the first one is a type of Mammillaria I'm sure and the last one i think is a Echinopsis peruviana

[teo]

#1 - Mammillaria (maybe melanocentra)
#3 - Euphorbia tirucalli or Rhipsalis baccifera - it's hard to tell from the picture. If it has white sap it's Euphorbia

[kaitlyn25]

one is not a melanocentra

and my columnar forms a star of 5 not six if that helps

[teo]

#2 - Cereus validus or forbesii (or something else)

[kaitlyn25]

I looked into it and I lean more towards the cereus forbesii (now I really what the spiral version of the species!)

[kaitlyn25]

is it possible that number one could be a Mammillaria mammillaris?
