From a link within the Wiki page that McGrath linked to:

"Dan Warner, of Fraser, Mich., writes, "Can you supply me with a word that rhymes with 'orange'?"


To answer your question, I got in touch with Hilary B. Price. As the cartoonist who draws the strip "Rhymes With Orange," she may be the world's expert on this subject. Price told me, "Marilyn vos Savant, who writes 'Ask Marilyn' for Parade magazine, claims there is a word 'sporange.' But the word is not in my dictionary."

"Sporange" isn't in most dictionaries. It does appear in Webster's Third Unabridged and in the enormous Oxford English Dictionary, both of which say it's a variant of "sporangium," a botanical term. Webster's Third gives two pronunciations for "sporange": the one you'd expect and "spuh-randj," with the accent on the second syllable. "Spuh-randj" is the only pronunciation given in Oxford. So although "sporange" looks as if it rhymes with "orange," whether it really does is debatable.

There is a hill in Wales called the Blorenge—but that's a proper name, not an ordinary word. Hilary Price told me she didn't know of any single rhyming word, either. "As far as I'm concerned," she said, "the closest rhyme is 'door hinge.'""

Curiouser and curiouser....
