Saraca indica is an evergreen flowering tree which grows to about in height, though some sources describe it as growing to . The trunk can reach up to in diameter. The bark is dark brown to almost black in color and has a warty and uneven surface caused by
lenticels. Fractures in the bark expose thin whitish layers. The leaves are compound and
paripinnate, each leaf has 2–4, sometimes 1–7, pairs of leaflets along a , sometimes up to ,
rachis. The leaflets are typically long by wide, sometimes long by wide. Leaflets may be elliptic to lanceolate in shape; their bases may be obtuse, rounded, cordate or cuneate; tips may be obtuse or acute, sometimes acuminate. The leaflet pairs closest to the leaf stalk are usually smaller than the rest. They have a
glabrous surface; young leaves flush white, pink, or purple and hang pendulously, turning green as they mature and are brownish when dry. Inflorescence is a diameter
corymb with slender branches, with
apetalous,
bisexual flowers with yellowish orange sepals.
Bracts are by in size, ovate to oval shaped, and
fugacious.
Bracteoles are long by , ovate to oval-oblong shaped, upright and spreading, may be persistent or fugacious when they fall off during maturity, and are orange-colored. The
pedicel is long, long including the part above the bracteoles, and bibracteolate at the juncture with a long and narrow
hypanthium. The
receptacle is long. The 4 petaloid
sepals are by in size, obtuse or rounded at the tip and spreading, and orange-reddish in color. The
stamens, 6–8 in total, sometimes 5–10, are
exserted and conspicuous. The
ovary is
pubescent along the margins, with 6–8 ovules.
S. indica has 6–8 ovules whereas
S. asoca has 8–10 and up to 12. Both pods are oblong, but
S. indica pods may be narrowly oblong-lanceolate while
S. asoca pods may be elongate-oblong or
scimitar-shaped; both species' pods can grow up to a similar size but
S. indica have smaller lower size range of , where
S. asoca pods have a size range starting at , being generally longer than
S. indica. The species also differ in native distribution:
S. indica, despite its name, is native to most of
Mainland Southeast Asia and
Western Indonesia while
S. asoca is native to the
Indian Subcontinent and
Myanmar west of the
Irrawaddy River. For its part,
Saraca asoca is also often misidentified as
S. indica, and in
India as of 2014, pharmacological researchers,
ayurvedic physicians, herbal industries, and several publications continued to erroneously refer to
S. asoca as
S. indica. Saraca is sometimes confused with the false ashoka,
Monoon longifolium, which is a lofty evergreen tree native to India. It exhibits symmetrical pyramidal growth with willowy weeping pendulous branches and long narrow lanceolate leaves with undulate margins. The false ashoka tree is known to grow over 30 ft in height. Species of
