Mammillaria chromosome count database?

Recommended Posts

Is there a database hidden somewhere on the web listing chromosome counts and ploidy of species of genus Mammillaria like the one for Salvia[*] ?

The bastard genus doesnt stick to the traditional 2n=22 :lol:

I keep wasting time making crosses that I eventually find out didnt even have matching chromosome numbers and I cant find a list of numbers!

Heres a start:

albilanata 2n=2x=22
angularis 2n=2x=22
armillata 2n=2x=22
asteriflora 2n=2x=22
bocasana 2n=2x=22
boolii 2n=2x=22
bombycina 2n=2x=22
brandegeei 2n=2x=22
compressa 2n=4x=44
crucigera 2n=2x=22
decipiens 2n=2x=22
dealbata 2n=2x=22
dixanthocentron 2n=2x=22
elegans 2n=2x=22
flavicentra 2n=2x=22
gemimspina 2n=2x=22
grandiflora 2n=2x=22
gummifera var. applanata 2n=2x=22
gummifera var. meiacantha 2n=2x=22
haageana 2n=2x=22
hahniana 2n=2x=22
huitzilopochtli 2n=2x=22
lanata 2n=2x=22
microcarpa 2n=2x=22
muehlenpfordtii 2n=2x=22
occidentalis 2n=2x=22
parkinsonii 2n=4x=44
parkinsonii 2n=8x=88
plumosa 2n=2x=22
prolifera 2n=2x=22
prolifera (Cuba) 2n=6x=66
prolifera (Haiti) 2n=4x=44
rhodantha 2n=2x=22
ruestii 2n=4x=44
san-angelensis 2n=2x=22
sempervivi 2n=2x=22
supertexta 2n=2x=22
vaupelii 2n=2x=22
woodsi 2n=2x=22
wrightii var. wilcoxii 2n=2x=22
zeilmanniana 2n=2x=22

Hi Auxin, im sure there is one somewhere but i dont know where to find it right now. There are some international Workgroups devoted to Mammillaria and i´ll see if i can find some contact info for you. If theres someone that can help you, its them. bye Eg

I had a M. bocasana make a fruit with M. sneaky-neighbor-cactus so I had to look this back up :P

In the doin' I organized my data and put it in post 1, it covers about a fifth of the genus.

And it looks like I may have got a few M. bocasana X M. rhodantha F1 seeds, yay.
