I12 THE HISTORY OF CREATION. 
plants with enclosed seeds, the Monocotyle and Dicotyle, 
it is exceedingly probable that the Dicotyledons developed 
out of the Gnetacez, but that the Monocotyledons developed 
later out of a branch of the dicotyledons. 
The class of one sced-lobed plants (Monocotyle, or 
Monocotyledons, also called Endogenze) comprises those 
flowering plants whose seeds possess but one germ leaf or 
seed lobe (cotyledon). Each whorl of its flower contains 
in most cases three leaves, and it is very probable that the 
mother plants of all Monocotyledons possessed a regular 
triple blossom. The leaves are mostly simple, and traversed 
by simple, straight bunches of vessels or “nerves.” To this 
class belong the extensive families of the rushes, grasses, 
lilies, irids, and orchids, further a number of indigenous 
aquatic plants, the water-onions, sea grasses, ete, and 
finally the splendid and highly developed families of the 
Aroideze and Pandanez, the bananas and palms. On the 
whole, the class of Monocotyledons—in spite of the great 
variety of forms which it developed, both in the tertiary 
and the present period—is much more simply organized 
than the class of the Dicotyledons, and its history of 
development also offers much less of interest. As their 
fossil remains are for the most part difficult to recognize, 
it still remains at present an open question in which 
of the three great secondary periods—the Trias, Jura, 
or chalk period—the Monocotyledons originated. At all 
events they existed in the chalk period as surely as did the 
Dicotyledons. 
The second class of plants with enclosed seeds, the two 
seed-lobed (Dicotyle, or Dicotyledons, also called Exogenze) 
presents much greater historical and anatomical interest in
