An accidental hybrid, probably made by hummingbirds visiting a greenhouse, is almost certainly a cross of (balbisiana x pseudobaileyi). This plant occurred amongst a group of seedlings of Tillandsia balbisiana supplied by a South American nurseryman. The shape of the plant is rather classic balbisiana in all aspects including size. The leaves though are semi-terete and have the striping like the T. pseudobaileyi.
The inflorescence is like balbisiana in shape and size but has the color of pseudobaileyi. One can never be sure of such a cross, but in my experience I have never seen a hybrid that appeared as obvious as this one. A very striking plant.
