Iq the pumpkin and baao, the seed-leaves (cotyledons) are lifted above the flurlace of the soil in germination. Iq the corn and pea. tne cotyledons are not lifted above the surface of the soil in germination. We observe that the pea has also a pair of cotyledons (c), that have not separated to the same extent as those of the bean and pumpkin, and are still beneath the soil. The corn, in common with other plants of its class, as sorghum, sugar cane, the reeds, grasses, etc., has but one cotyledon, and that is not easily made out without dissecting the seed. In Fig. 12, which shows a cross section of the germinating corn grain, the cotyledon appears at cot. The plants having two cotyledons form a verj' important class in botany, known as Dicotyledones (di-co-tyl-e'-dones);.
