Shrubs or trees, typically with a single terminal bud, but the stem 
sometimes branching, the branches erect or diffuse. Leaves aggregated at 
the end of the stem: blades plaited, pinnate, or flabellate. Flowers per- 
fect, polygamous, or dioecious, on axillary compound spadices. Perianth 
of 6 fleshy members in 2 series. Androecium of 6, or 9-12 stamens. 
Gynoecium of 3 distinct or united carpels. Fruit drupaceous or baccate.

Stem, and branches, with a crown of leaves. Leaf-blades flabellate 
or A and plaited, or pinnate, the segments induplicate or 
reduplicate, long-petioled. Inflorescence at first included in a large braet 
(spathe), from which it ultimately protrudes, borne in the crown of leaves 
or on the stem below it, the usually copious branching of the spadix most > 
evident in fruit. Perianth white, yellowish, or greenish.—About 150- 
. genera and 1,200 species, most abundant in the tropies. 
. Leaves with pinnate blades, the divisions often separated, 
sometimes clustered. I. PINNATAE.
