BOOTAN MOUNTAINS. 



Acorus the cells are filled with mucilage. The ovula are 

 solitary. 



The nucleus ? has so much the appearanee of an inner 

 coat, that I hesitate in deciding whether it is really nucleus 

 or not, at least at this period of its development. Analogy 

 tells us it is nucleus, both when ArordesB generally are consi- 

 dered as well as the ordinary mode of development of ovulum, 

 the nucleus being the preexisting part. No process of distinc- 

 tion shews that it is a tegument, on the contrary, the opaque 

 line that so much resembles the canal of an ordinary coat, dis- 

 appears. Thus a second tig 20 is not the nucleus, but is owing 

 to some condensation of tissue. A truncated apex is unusual 

 in nuclei, their form in this directio being almost always apicu- 

 late and even mamimlate.
