[OGD] Info on yellow form of Phal. lobbii?

[MGOrchids]

A couple of months ago I bought several plants of what are supposed to be a yellow form of Phal. lobbii from Best of Thai Orchids.  (It's labelled "var. brunescens" for what that might be worth, but the guy was very clear about it being a "yellow" form.)  I've found a couple of photos on the web of P. lobbii with yellow in various flower parts but the vendor didn't have a photo and I don't know which these are supposed to be.  For the curious, the photos are at, respectively: http://perso.wanadoo.fr/bernard.lagrelle/Lobbii/anglais/Phalaenopsis%20lobbii%20anglais.htm and http://www.phals.net/lobbii/index.html .

Anyway, this is a long-winded preface to the question whether anyone knows anything about these plants.  Have any of these forms been formally described?  Are they from the same geographic area as the standard P. lobbii?  If anyone grows it/them, do you treat them differently than the standard lobii ? My plants, or several of some of them anyway, have shown signs of foliage and/or spike growth, but no new root growth yet.    If I'm doing something wrong, I'd like to fix it before I lose them!  Thanks.
