arbor infelix

ARBOR INFE´LIXAs applied to trees, felix and infelix imply fruit-producing or the reverse (Paul. ex Festo, p. 92; Verg. G. 2.81; Plin. Nat.24.68). Infelices (se. arbores) autem existimantur damnataeque religione quae neque seruntur unquam neque fructum ferunt (Plin. Nat.16.108). Those trees also which bore black berries and black fruit, and were accordingly sacred to the gods of the lower world, were called infelices (Macrob. Sat. 2.16.2). Such trees appear to have been used for the patibulum and crux (Cic. Rab. Perd. 4, 13; Liv. 1.26. See generally Rein in Pauly, s. v.).

(1) A tree that was either sterile, or produced black berries and fruit (Plin. H. N. xvi. 108).

(2) The cross. See Crux.
