try delenatii (rose scent), malipoense (raspberry scent), hangianum, emersonii, kolopakingii
There is a delenatii purfume up for sale actually...made in japan
My instincts tell me that if you are lucky you can get a faint scent from bellatulum or niveum or other brachys possibly. Didn't you say one of your white complexes was fragrant? It does have brachy in it's genes.
