Os elfos e os hobbits tinham orelhas pontudas sim, apesar dos pequenos as terem apenas 'levemente'. As orelhas de Elfos estão descritas em um livro: The Lost Road, da série History of Middle-Earth. O trecho original do livro está abaixo:
"Las (1)
*lasse 'leaf': Q lasse, N lhass; Q lasselanta 'leaf-fall, autumn', N lhasbelin (*lassekwelene), cf. Q Narquelion [ KWEL ]. Lhasgalen 'Greenleaf' (Gnome name of Laurelin). (Some think this is related to the next and *lasse 'ear'. The Quendian ears were more pointed and leaf-shaped than [human].)"
As orelhas "apenas levemente pontudas" dos hobbits é que são descritas nas Letters de Tolkien: " I picture a fairly human figure, not a kind of 'fairy' rabbit as some of my British reviewers seem to fancy: fattish in the stomach, shortish in the leg. A round, jovial face; ears only slightly pointed and 'elvish'; hair short and curling (brown). The feet from the ankles down, covered with brown hairy fur. Clothing: green velvet breeches; red or yellow waistcoat; brown or green jacket; gold (or brass) buttons; a dark green hood and cloak (belonging to a dwarf)."
Além desse outro trecho da Carta 27:
"I am afraid, if you will need drawings of hobbits in various attitudes, I must leave it in the hands of someone who can draw. ... I picture a fairly human figure ... fattish in the stomach, shortish in the leg. A round, jovial face; ears only slightly pointed and 'elvish'; hair short and curling (brown)."
Quanto a meio-elfos, duvido que eles tenham orelhas pontudas como elfos, deveriam ser como humanos com pequenas características élficas. Porém, eles poderiam sim ter orelhas pontudas levemente, como hobbits.
