 extending into branches" (Lindley);

 '= Embryo-sac Tubes; -' Nod'ule, 

 the same as Embryo Buds; ~ Sac, 

 the cell in the ovule in which the

 {yivvao), I bring forth), belonging to 

 the development of the embryo; •^ 

 Bod'ies, in Mucorini, naked masses 

 of protoplasm apparently derived 

 from the nuclei, at each end of the 

 zygospore, ultimately fusing to- 

 gether, becoming ~ Spheres, then 

 surround themselves with a double 

 cell-wall, and finally become Km-

 to an embryo resembling the adult 

 form; heteroblast'ic >-', when the 



embryo differs widely from the 

 adult form it is not borne direct,

 (Crozier) ; embryon'ic, rudimentary, 

 in an early stage ; '- Appen'dage, 

 the apical portion of the suspensor 

 in grasses (V^mes); Em'bryophore 

 {<pop4(a, I carry), in Eqiiisetum the 

 homologue of the suspensor of 

 Phanerogams and ScIagineUa, the 

 lower of the two cells first cut oflF 

 by a septum in the oosphere, then 

 again separated, and this time 

 forming the lower two of the quad- 

 rants, one becoming the " font," the 

 other the first root ; Embryophy'ta 

 ((bvrhv, a plant), plants possessing 

 embryos, divided into ~ Sipbono-
