One of the more unusual nature names, that of a variety of pine tree. Tam might sleeken and modernize it.

A hardwood tree native to Africa, India and other tropical regions, which bears sweet pod-shaped fruits which are used as a flavoring in many world cuisines, including Indian and Filipino. A rare and intriguing nature name which could honor an ancestral Tammy or Tamar.

Also know as the salt cedar, a plant known for enduring harsh conditions. This makes Tamarisk an intriguing nature name, suggesting resilience and strength, similar to the name Oak for boys.

A Near Eastern favorite, with an agreeable, evocative sound.

This adorable name of the young daughter on "Big Love" might be thought of as a variation of Tansy, an obscure flower name whose star may rise on the heels of such current favorites as Lily and Daisy.

We've had Apples, Plums, Peaches, Cherries, and Berries added to the fruit basket: you could be the first to pick a Tangerine.

A pretty, rarely used Greek name, Thalassa is the ancient personification of the sea, particularly the Mediterranean, who is sometimes considered the mother of Aphrodite. In 1991, a newly discovered moon of Neptune was dubbed Thalassa.

Thallo, the Greek goddess of spring, buds, and blooms has a decidedly less flowery name than her Roman counterpart, Flora. Thallo is one of the Horae in Greek mythology: goddesses associated with the cycle of life, growth and the seasons.

Thebe is the name of more than one daughter of Zeus, according to some myths, and is also the name of a moon of Jupiter. Thebe rhymes with Phoebe and may appeal to lovers of that name.

This name of the mythological mother of Achilles might suffer from English speakers making the rhyming association to the word fetus. The traditional Greek pronunciation might alleviate that problem.

Quirky and charming flower name. Thistle is Scotland's national symbol.

The thistle is the botanical emblem of Scotland and would make a good if unusual patriotic choice for people with Scottish heritage. One of the few flower names that could be worn by a boy with as much ease as a girl.

Rose and Briar are popular, and Hawthorn is cool – so why not the equally prickly Thorn? Add an E to give it a surnamey spin.

Fragrant herb often used for cooking, but scarcely as a name.

A South Sea Islander name that may be adopted by the wider world, with its simple spelling and lovely nature meaning.

The name of an important ancient Roman emperor, Tiberius might sound a bit heavy for a modern boy to carry, but with the rise of Atticus, Tiberius and brothers begin to feel more baby-friendly, much in the same way as Old Testament names like Elijah and Isaiah have been rejuvenated.

As likely to be tied to the detergent as to the rhythms of the ocean.
