I don`t see The Three Flowers, amazing how this was passed over, as it is in the DT, the song comemerates, Wolfe Tone, Michael Dwyer and Robert Emmett.
And written by Arthur M Forrester and not included in the DT,

                   The Felons of our Land

    Fill up once more, we`ll drink a toast to comrades far away,
       No nation on earth can boast of braver hearts than they,
And though they sleep in dungeons deep, or flee outlawed and banned
   We love them yet, we can`t forget, the Felons of our Land.

In boyhood`s bloom and manhoods pride fordoomed by alien laws,
Some on the scaffold proudly died, for holy Ireland`s cause,
And brothers say, shall we, today, unmoved by cowards stand,
While traitors shame and foes defame, the Felons of our Land.

Some in the convicts dreary cell, have found a living tomb,
And some unseen untended fell within the dungeons`s gloom,
But what care we, although it be, trod by a ruffian band,
God bless the clay where rest today the Felons of our Land.

Let cowards mock and tyrants frown, ah little do we care,
A Felon`s cap is the noblest crown an Irish head can wear
And every Gael in Inishfail, who scorn the serf`s vile brand,
From Lee to Boyne, would gladly join the Felons of our Land.
