272 ACOTYLEDONOUS PLANTS, 



Change in grains while attached to the axis, no elongation of 

 the paraphysiform hairs. 



2nd. General Objections. Moniliform filaments of Azolla 

 on the capsule of Salvinia. 



Dissimilarity of the process in the two. 



The brown matter is opaqueish and grumous. 



The general development of the granules is from above down- 

 ward, beginning with grume containing slightly moving points. 



Some of the cells contain sometimes one or two large glo- 

 bules, which are perhaps only gigantic granules. 



A developed cell contains granules and globules of all sizes, 

 but especially the former, endowed with motion. 



Hairs are found just below the conical growing point, the 

 base of which is beset with protuberant cells to fulcrum 

 roots and hairs. 



In mature roots I do not discern them. Appearances such 

 as suggest a general development of the contents from above 

 downwards, are observed, and also an enlargement of the 

 ganules. 



Note. — The foregoing remarks appear to have been written at various 

 periods between 1835, and 1845. They bear no dates.
