CLASSIFICATION OF TREES AND SHRUBS ACCORDING 

 TO THEIR FRUITS AND SEEDS. 



I. SEED NOT IN A FRUIT, BUT EXPOSED FROM 

 THE FIRST ; SINGLE, OVOID, BROWN AND NUT- 

 LIKE, INVESTED BY A CUP-LIKE SOFT SCARLET 

 ARILLUS. 



Taxus baccata, L. Yew (Fig. 69). The apex of the 

 seed is slightly pointed but devoid of scar; base with 

 annular surface of attachment. Seed about 10 mm. long, 

 very slightly compressed. Scales at base of arillus. 



The proof of the morphological nature of the so-called 

 Yew " berry " depends on the study of development ; but 

 the absence of any stigmatic scar, the simple structure of 

 the seed-coat, and the endosperm and embryo can be 

 determined in the field. 



Any superficial resemblance to an Acorn in its cup is 

 easily discounted by comparison and especially on careful 

 dissection. 



II. SEEDS ENCLOSED BETWEEN THE SCALES OR 

 WITHIN THE WALLS OF A FRUIT. 



A. SEEDS ON THE INNER FACES OF THE SCALES OF [For (B) 



A DRY WOODY CONE, AND SHED FROM BETWEEN S6e P * 78 

 THE SCALES ON RIPENING. 



(1) Cones sessile, and composed of single or [For (2) 

 double scales closely imbricated on an axis. see P- 78
