This cactus was covered with flowers during the day (bright yellow outside, creamy white inside). This is a picture from last year. I'm pretty sure it's a Parodia; any idea of species? (leninghausii?) Many thanks for any help.
If it was a Parodia, it would be flowering from the apex and the flowers would have hairs and bristles on the outside. Lateral flowering and naked flowers make it a Weingartia.
I think it's a Weingartia sp. ... but I don't know the species... :((( http://www.cactusbase.hu/modules.php?name=Kaktusz&pa=nemzetseglista&cid=301&lis=2
Many thanks, Lila. I've pulled pics and it does look like a Weingartia. I'm very happy to have that. Thanks again!
Thanks, Steve! It's always good to know the difference/how to tell. The books I've got don't do much more than show pics...and one cactus starts looking like another after your eyes cross! Thanks for the info.
