In order to add placeholder to the form fields you can do make following changes to the model files . Note, this will work with most field types.

Model db.py

db.define_table('reference',

    Field('is_enabled', 'boolean', default=True, label=T('Enabled')),

    Field('name', 'string', required=True,length=256, label=T('Name'),widget=widget(_placeholder='One-two word description', _readonly=False)),

    Field('title', 'string', required=True, length=512, label=T('Title'),widget=widget(_placeholder='e.g. Database Abstraction layer ', _readonly=False)) ,
