We obtained at a plant rescue event several pots of Citrus x meyeri that were labeled as such, plus one unlabeled plant whose leaves were sufficiently similar not to suspect that it was anything different. But now it has started growing and there are significant differences. While fresh growth on the Citruses we have - both vegetative and flowers - emerges uncovered, on the mystery plant it starts as hairy buds: small for twigs and much larger for flowers.

One vegetative bud is exactly in the center of the picture pointing away. The fresh growth on the left retains two poorly visible, withered remaining scales above and below. The larger flower buds are on the right. Their scales have fallen off from one bud and a similarly shaped folded flower with white petals is revealed (not shown).
