Tillandsia 'Kashkin' is most likely a naturaly occouring hybrid collected by Michael Kashkin sometime in the 80's in Bolivia. This plant used to be called T. 'Inca Gold'
It is a very saught after plant that is similar to T. jucunda but has flowers that start of yellow and fade translusent. The flowers are exquisitely and uniquely scented.
These are nice large flowering size plants. Most have a pup on them as well.
