What is the difference between paph. primulinum verses primulinum variety 'aureum'?
It maybe unnecessary but it sure is useful.The yellow form/variety (does anyone have any population data?) was the type, so Paphiopedilum primulinum refers to the that yellow fvariety. The addition of 'aureum' is unnecessary and botanically incorrect. P. primulinum does have a "normally" colored variety, P. primulinum var purpurascens.
I don't deny it may be useful, I'm just trying to give the official ICBN explanation.It maybe unnecessary but it sure is useful.
Maybe they try to separate the yellow ones from the green /white ones?The yellow form/variety (does anyone have any population data?) was the type, so Paphiopedilum primulinum refers to the that yellow variety. The addition of 'aureum' is unnecessary and botanically incorrect. P. primulinum does have a "normally" colored variety, P. primulinum var purpurascens.
I'll concur with Zach on this one.
However, over the past year or so, I've also seen Paph. primulinum var. alba listed from several wholesalers and vendors, and in some cases, the plants are simply the typical yellow form. In other cases, though, the blooms are mostly white (with some green) rather than yellow. The Wikipedia photo appears to be a white one, as does this one (though this one is also over-exposed): http://www.coluna-da-sal.com/orchidarium/fotos_6/orq-0821_-_paphiopedilum_primulinum_var_album.jpg
In some cases, I think that people actually intend the "var. alba" etc to refer to the white variety. As far as I know, it hasn't been officially described, so it's just a trade name. Either way, the "aureum" should refer to a yellow bloom, which is the type form... so it should just be primulinum.

I'm not sure what you are asking, but Paph Pinocchio= glaucophyllum x primulinum. Now, depending on which form of primulinum you use, a different result could be expected. The var. purpurascens generally gives larger flowers than primulinum. The color influence is also different as primulinum will give more yellow.So my plant would be a cross w/ primulinum v. purpurascens that is album.
