Problems with distinct

Any idea why this works:

SELECT distinct(g.groupname), g.id, g.p_id FROM onp_group g, onp_group g2
WHERE g.id IN(SELECT g2.id UNION SELECT group_id FROM onp_group_children WHERE
child_id = g2.id)
AND g2.id IN(1,2,109,105, 112);

And not this:

SELECT g.id, g.p_id, distinct(g.groupname) FROM onp_group g, onp_group g2
WHERE g.id IN(SELECT g2.id UNION SELECT group_id FROM onp_group_children WHERE
child_id = g2.id)
AND g2.id IN(1,2,109,105, 112);

The *only* difference is that the distinct-clause changed place...
