510 NOTE. 



the leaves appeared to be arranged some ou the outside, otbei*8 on the 

 inside, of an erect hollow cylinder, some six inches in height. The 

 oldest leaves were outside, the youngest within, so that the appeai*ance 

 presented was as if the summit of the axis had been pushed or drawn 

 in, much as the finger of a tight glove might be invaginated in with- 

 dramng it from the hand. 



The plant in question thus furnishes an actual illustration of the 

 supposititious case mentioned at p. 482.
