instances I found seedlings and young individuals of different 
ages in dense patches ata distance of at most 30°™ from isolated 
mother plants. Owing to the length of the stalk the fruit can 
reach at most the distance of 15°™ from the center of the plant. 
There does not seem to exist any arrangement for the spreading 
of the seeds. 
_ The seeds were found germinating in February. The coty- 
ledon remains with its tips for some time in the seed, while its 
middle portion breaks above the ground by a knee-like curva- 
ture (fig. 7). Then it leaves the seed and stretches out, being 
the first green leaf of the plant. The primary root, 1™ thick 
and beset with long hairs, reaches only 3° inlength and does not 
_ branch. It has the central cylinder 2-archic, anda thick cortex. 
fe The latter becomes filled with starch-grains, except in the basal 
= portion, where starch is almost absent; but here the undulation 
of the endodermis points to a slight contraction. After germi-—
