LEMNA. 99] 
11. Embryo, slit visible distinctly. 
12. Long section of another seed, through the testa. 
13. Albumen, partly deprived of the inner tegument. 
14. Do., separated. 
15. Embryo seen laterally. 16, seen in front. 
I conclude that the line seen, on the embryo in figs 9, Le 
is accidental. In Lemna minor of Calcutta it does not exist, 
and even in this, would appear to be limited to one side. 
From this it would appear that the radicle of the embryo 
does not point tothe foramen, or that the radicle of the em- 
bryo is split, to admit of the egress of the plumule; which is 
the greater anomaly ; the non correspondence of the apex of 
the radicle to that of the nucleus, or the complete inversion 
of the direction of the plumula? the study of the Germination 
can only settle this point.

I. Plant. 
2. Do. Single frond. 
3,4, 5,6,7,8. Spathe and genitalia at different periods,

9, 10, 11. Genitaliaat different periods.
