COTYLE'DON. (KOTv\r)wv, Gr. cotyledon, 

 Fr.) The side lobe, or seed-lobe of seeds, 

 furnishing nourishment and protection to 

 the corculum, and forming the chief bulk 

 of the seeds : these lobes swell and ex- 

 pand in the ground, and as the stem as- 

 cends they are usually raised out of the 

 ground, assume a green colour, and per- 

 form the functions of leaves until the 

 young leaves unfold, when they generally 

 wither. The cotyledon is found at the 

 point of union of the radicle and plu- 

 mule. The most essential difference in 

 the structure, mode of growth, and cha- 

 racter of the plants growing from the 

 seeds, is found connected with the num- 

 ber or position of the cotyledons. Those 

 plants, the seeds of which have only one 

 cotyledon, or if more, these alternate on 

 the embryo, are called monocotyledonous. 

 All monocotyledonous plants can be re- 

 cognised without any difficulty, by a cha- 

 racteristic feature of the leaf, the veins of 

 the leaf being parallel, and not reticu- 

 lated ; all the palms, the tulip, lily, aloe, 

 &c. are instances. Those plants which 

 have two cotyledons, and those opposite, 

 are called dicotyledonous ; all dicotyle- 

 donous plants have the veins of their 

 leaves reticulated.
