Lime fruits

Not the citrus fruits but the seed-containing fruits, like berries, of the linden tree (Tilia sp).  There are several species of lime tree but they nearly all share two attributes:  

(a) the lopsided-heart shape of the leaves and 

(b) the fruits in a bunch on a stalk with a pale bract to help them fly.

On some trees the bracts almost look like flowers, they are so bright and numerous.
