LXT. ATIALTACE/F.. 
the rhachis often articulate, the petiole dilated at the base or the dilatations 
united in an intrapetiolar stipule. Flowers small, often greenish or purple, in 
umbels heads or rarely racemes, which are usually disposed in large terminal 
racemes or panicles, the umbels rarely solitary or in compound umbels. Bracts 
usually small and often inconspicuous or none. Flowers frequently polygamous, 
the ovary entirely abortive in the males, the stamens often smaller or rarely 
wanting in the females. 
With the exception of a very few species in the temperate regions of the northern and southern 
hemispheres, the Order is confined to the tropics in the New as well as in the Old World.

Generally speaking. Araliacew differ front VmheUifer<r by their tall shrubby or arborescent 
habit, large leaves, paniculate inflorescence, valvatc petals, entire disk and drupaceous fruits, 
but every one of these characters breaks down in some exceptional case, and some have proposed 
to unite the two Orders. But such connecting links occur in the case of even the most natural 
Orders, and it appears to me that if .tstrotricha and Horsfieldia are transferred from Vmbcllifcne, 
where they have been hitherto placed, into A raliaccee. there is really very little difficulty in 
drawing the line of demarcation between the two.- Benlh.
