(2) Cotyledons, or Seid-leavea, tho first leaves, often thick and flcsliy, as in tho Bean (Fig, ), l,iit some- times thin and luaf-Iike. (.'!) Plumule^ tho bud at tho top of the radicle (Fig. 204). (b) Albumen ov EndospiTvi, when present; nourishing matter stored up outside tho embryo, as shown in the ihaded portion of Fig. 200, tho liglit part in the centre being tho embryo. Kind. Dic'OTYLEDONOi's; having two cotyledons (Figs. 207, 208, 200). M()\()(joTVi,Ei)()\oiis: having only one cotyledon (Figs, 210, 211, 212), P()()Tvi,Ki)0\ouf4: having several cotyledons (Fig, 20G). This is rare. : having no cotyledons (rare). Ali!\()i;s : having albumen or endosperm in addition to the embryo (Figs. 20(i, 210). Tho following terms apply to the folding of the parts of the embryo in dicotyledonous seeds : (a) .1 when the radicle is turned so as to touch tlio edges of the cotyledons (Fig. 213). (b) Incumhetit, when the radicle is turned so as to lie against the back of one cotyledon (Fig. 214). (c) Conduplicate, the same as incumbent with tho addition that the cotyledons are curved so as to partly infold tho radicle (Fig. 215). Nature and Use of the Parts of the Flower. All the parts of the flower are leaf-forms (phyllomes), differing from ordinary foliage-leaves, be
