INTRODUCTION TO BOTANY. : 213. 
At the tip, apieilaris. Placed opposite the hile. Col- 
chicum. 
Vague, vagus. Placed in the perisperm, but neither at 
the bottom, top, or side of the seed. 
Nestling, nidulatus. Placed in a sac formed by a fold of 
the inner skin of the seed. Commelina. 
q White, albus, lacteus. Most embryos. 
Yellowish, /utescens. Ribes spinosum glabrum. 
Green, viridis. Acer majus, Pistachia Terebinthus. 
Leadcolour, plumleus. _Adchinops. 
Purplish, purpureus. Bidens and Zinnia when the seeds 
are fresh. 
{| Large-footed, macropodius. ‘The radicle very large, 
and bulging out like a head. 
Large-headed, macrocephalus. The cotyledons swelled 
out into a mass much larger than the other part. 
Roots within, endorhizus. Radicles growing from the 
base of the embryo and piercing the covers. 
Roots without, exorhizus. Radicles completely developed 
in the embryo, and only lengthening in germination. 
Roots united, synorhizus. Radicle united in some degree 
with the perisperm. 
CoryLEDONs. 
Cotyledones, Lobi, Valvee seminum. The part of the 
kernel that forms the first leaves of the plant during germi- 
nation. Pl. 14, fig. 12; pl. 15, fig. 19, 22 c; pl. 16, fig. 13. 
In one-cotyledon embryos, the cotyledon forming nearly 
the whole mass of the embryo, the external characters are 
common both to the embryo and the cotyledon, and it is 
indifferent whether it be said that the embryo or the coty- 
ledon of holcus is bucklershape; but in other embryos, 
the cotyledons are in general very distinct. 
Fleshy, Cotyledones carnose. ‘Thick, juicy, firm, and 
breakable. Corylus, Faba, Amygdalus communis, A. 
Persica. 
Leaflike, foliacee. Thin, and frequently ribbed like 
leaves. Nyctaginez, Tilia, Cassia Fistula, Kuphorbiacez. 
Pl. 14, fig. 12. 
{ Dotted, punctate. Surfaces with either transparent 
points, Aurantiaceze; or coloured ones, Anagallis when 
germinating. 
Ribbed, zervate. Surface ribbed. Tilia, Mirabilis Jalapa. 
Ribless, enerves. Faba.
