 of asparagus is com- 

 posed of modified 

 branches. The true 

 leaves of asparagus 

 are minute whitish 

 scales (a, Fig. 147) . 

 The green foliage is 

 produced in the axils 

 of these scales. On 

 the strong spring 

 shoots of asparagus, 

 which are eaten, 

 the true leaves 

 appear as large 

 scales (<i, '(, Fig. 148 



scales persist on tin- base of 



the asparagus plant, even in the tall. In the spe- 

 cies of greenhouse of ornamental asparagus, the 

 delicate foliage is also made up of green leaf- like 

 liranches (Fig. 149). In sonic eases the true Leaves 

 fall after a time, and there is little evidence left. 

 The strong new shoots usually show the true 

 leaves plainly (as in Pig. 150). Branches which 



simulate haves are known as cladophylla 



lar, cladophyllum). The broad Hat 



of florists' sinilax (common in glass- 



houses) are eladophj 11a.
