148 GERMINATION OF THE CABBAGE PALM. 



The same nut farther advanced in germination, showing the micro- 

 pyle e, swelling from the supply of juices derived from the soil, and 

 thence become dilated and soft. Its root-sheath sends out the first 

 radicle, now branching, , and four side shoots more, d. The sheath, 

 f, with a cleft tip, sends out the gemlet from its bosom, whose outer 

 leaf g, opened with a slanting tip, is pierced by the inner leaf still 

 unopened.

11. The embryo taken from the germinating nut, its central part 

 swelled into various twistings (gyros)a, which upon the pithy part of the 

 albumen being liquified, break out into white teat-like processes, with 

 depressions between, and closely applied, thence exhaust the nutritive 

 juice absorbed into the inner parts, by means of the neck of the em- 

 bryo, b, which is cylindrical, and placed within the shell of the seed. 

 The first radicle c, is bluntly tapering towards the base, and thence 

 sends off three branches, while the radiculoda swells up like a round- 

 ish scar. The sheath d, with the tip equally tapering, is pierced by 

 the tapering gemlet. 



12. The same things shown in a plant a little more advanced, where a 

 part of the nut having been removed, the central part of the embryo 

 a, is sent off twisted, and remaining within the horny albumen of the 

 shell variegated with rays b. The last are explained by the letters of 

 the preceding figure. 



13. The same plantlet deprived of its nut, and seen in a side view. 



14. A view of the internal structure of the parts of the germinating 

 plantlet, cut through the middle. The central part of the embryo a, 

 now moving in two directions, shows traces of twisting ; since from 

 these, the crown (limites) of the plant tending upwards and downwards, 

 runs. This original division of the plant into a ground and a solarsean
