united in bunches at the summit of the stem and branches, 
are elongated, unifoliolate, and entire. The flowers' present fine 
examples of what is termed localized inflorescence; they are 
usually disposed in alternate few-flowered cymes upon separate 
axes, often elongated, angular, and sometimes bearing leaves, and 
which after a longer or shorter rest, produce new cymes slightly 
distant from the preceding ones. These axes are separated 
from the stalk on a level with a leaf, whose axil they cannot 
be said to occupy, as they correspond with that of a leaf 
situated lower down, and from which they have been drawn up the 
stem to a higher level; sometimes even, as in Z. hypophyllanthus, 
they have been raised to a certain height along the midrib of an 
upper leaf, the inferior face of which then bears the floral cymes. 
Beside Hrythrochiton are placed several very analogous genera, some 
having regular, and others irregular flowers. The former are: 
Spiranthera odoratissima.
