Rutaceae - Rue family (which includes the citrus trees)>

Hercules-club Prickly-ash (Toothache) Zanthoxylum clava-herculis

Missed the flowers.  Very aromatic bush can grow to 15 feet tall but is most often shrubby.  Corky-based prickles on trunk and branches.  Leaves can have 5-19 leaflets, 1/2"-4 1/2" long with a shallow scalloped edge.  Close grained, soft wood.  Rough, 1/4" wide berries grow in clusters on long peduncles, greenish turning to brown. They hold onto the seed for a long time after opening.  The standard also is called a "toothache bush" and was once used medicinally to numb gums and wash itchy skin.

Bitter Orange (Trifoliate Orange, Flying Dragon, Hardy Orange) Poncirus trifoliata

This tree can grow to 30 feet tall, but I have only seen it as a bush.  Aromatic.  Lustrous, dark green bark.  Distinctive flattened spines, 1 1/2" long, grow from flared branches.  Leaves are under 3" long, winged petiole.  Missed the flower photo.  "Orange" is under 2" wide, bitter.  This plant is often hybridized with other oranges and Kumquats to produce varieties.  It is also used as a grafting base plant to improve hardiness.  Planted in a bucket, it will not grow large and can be used as a Bonsai.
