fascicled, or more rarely in short racemes (Zropical America). See

26. Serianthes Bunrn.—Flowers 5-merous (parts in order of 
magnitude), hermaphrodite or more rarely polygamous (of Jnga). 
Calyx thick, widely campanulate, 5-lobed valvate. Petals adnate at 
base to staminal tube, valvate. Stamens oo (very numerous), mona- 
delphous. Germen sessile -ovulate; style thin; apex scarcely 
dilated, stigmatiferous. Legume oblong-ovate, straight or falcate, 
plano-compressed or undulate, woody indehiscent, septate between 
transverse compressed seeds.—Trees, unarmed ; leaves large 2-pin- 
nate; pinne and leaflets unsymmetrically o-jugate; petiolar and 
jugal glands rather prominent; stipules minute or obsolete ; flowers 
in subcorymbose racemes near extremities of branches (Zropical Asia, 
South Sea Islands). See p. 46. 
27. Affonsea A. 8. H.—Flowers hermaphrodite or polygamous 
(of Serianthus). Carpels 2-6, free; ovaries c-ovulate. Legume 
(when young) linear, thick, straight; funicle of seed dilated into a 
fleshy aril.—Trees ; leaves (of Inga) abruptly pinnate ; stipules per- 
sistent, not spinescent; flowers in loose or subracemose axillary 
terminal spikes (Brazi/). See p. 47. 
28. Archidendron F. Murti.—F lowers of Affonsea ; calyx entire, 
evenly truncated; carpels 5-15, o-ovulate. Legume indurated 
coriaceous, bowed or variously twisted, without pulp, dehiscing late. 
Seeds transverse exalbuminous ; funicle short.—A tree; leaves - 
pinnate; pinne 1- or paucijugate; flowers umbellate-capitate near 
axils (Eastern subtropical Australia). See p. 47.
