FOREST FLORA OF BRITISH BURMA, 
SYNOPSIS OF NATURAL ORDERS. 
A. SEED-BEARING PLANTS or PHANEROGAMS. 
Plants bearing more or less complete flowers and producing 
perfect seeds, in which an embryo rests. 
Crass I. DICOTYLEDONS or EXOGENS. 
Stem, when woody, consisting of pith, of one or more concen- 
tric circles of fibrous tissue, and of bark on the outside. Embryo 
with 2 or rarely more cotyledons, the young stem in germination 
proceeding from between the cotyledons or from a notch at its 
summit. Flowers often 4- 5- or 6-merous. Seve net-veined. (By 
far the greatest portion of Burmese woody plants belong to this 
class.)

ovary with astigma. Seeds contained in a seed-vessel. Cadslelie 
usually 2 only.
