H. Tulip bulb (autumn resting stage). Cut through the middle of the bulb longitudinally and make 

 a drawing of the section, marking protective scales, bulb scales, and terminal bud. Look for axillary bud which 

 will form next year's bulb.

 the old bulb longitudinally and draw the section, shewing the new bulb arisen from an axillary bud formed in 

 the autumn, roots, etc.
