part is denoted by a slender line, as if it were the centre of vegetation ; 

 the salient point or primary nodule of the pith of the radicle b, whose 

 rudiments or plumelet of the caudex and frond c, d, may be perceived 

 budding from the centre and tending towards the ground. The side 

 part is seen remaining entire on the root-sheath e, like twin tubercles, 

 sending out two side rootlets, of which the upper f, partly open length- 

 wise, brings the pith into view ; but the other part or gemlet of the 

 plumelet, is involved in the base of the coleoptilon g, and this itself 

 consists of four imbricated sheaths ; the other part or the rudiments of 

 the stem {tigella), the hinge of the future evolution, swells out above 

 the dividing line h, in the form of a minute papilla. These figures, from 

 one to fourteen, are all one third the size of nature.
