yes, that is normally my viewpoint too

first of, it may seem that they don't look alike, however I have Sulcorebutia species that look a LOT like a Weingartia, for example look up: sp. HS213, sp. torotoro or W. nadae

in the case of Weingartia the following thing happened and imo made it impossible to ignore plant relationships except for nostalgic reasons:

the new cactus lexicon lumped all Rebutia, Sulcorebutia, Weingartia and Cintia plants into one genus, that was (like most lumping in the NCL) provisional.
that is why a lot of people still firmly believe these plants to be Rebutia, scientific research has caught up with that though... so to answer that, the NCL is outdated on these plants.
research has shown that Weingartia, Cintia and Sulcorebutia can not be seen separately, and that Rebutia isn't related at all, thus the revision into one genus.
so these plants were lumped, splitted and then lumped again, however this time on a more solid ground.

if you want to know more about the how and why, here are some articles about it, I recommend you use google translate, english summaries are probably available but I don't have them myself:

the revision of the genus:

taxonomic changes based on the revision:

an article in english on the relations between the genera rebutia, weingartia and echinopsis:

the research by Ritz et. al, including a very clear cladogram:

this may well be the last flower for the season but what a beauty!

Yellow flower?! I must say I'm shocked.

oh boy, I hope I'm not becoming known as that guy with the yellow flowers :oops:
to my defense: there is a hint of green in the flower

the only thing remotely brown about it are the tips of the outer petals, the rest is a slightly greenish yellow

Arjen, there's nothing at all wrong with yellow flowers. Yellow is a happy color, it attracts bees and such for pollination, and it's the color of the sun. Pretty soon we'll all be lamenting the cold, gray days of autumn and the lack of warm summer sun. So, I hope that gives you a reason (and everyone else) to love yellow! :D

when you like weingartias s.s. it's impossible not to admit you like yellow flowers, pretty much the same goes for copiapoa lovers
you did just give me an extra reason to like them ;)
