Nope, no descriptions. Just my observations on the one's I have. P. wilsonii does smell very good and sweet, but the fragrance of modesta is quite different and very grape koolaid. There's no mistaking that grape smell for anything else and it's very strong. P. wilsonii has a delicate fragrance. P. modesta grabs your nose and twists it. I have two modesta in bloom right now and the whole gh smells like a kid's birthday party!
