ITS KINDS. 



129 



cent fruit, snch as is popularly taken for a naked seed : but 

 plainly a ripened ovary, and shows the re- 

 mains of it« style oi stigma, or t)ic place 

 283 tivnn which it has 



^jXCi^ fallen. Of this sort 

 ,^ \ are the fruits of the 



Knttercup (Fig. 28G, 



2S7}, the Cinque-foil, and the Strawberry (Fig. 



L'70, 288) ; that is, the real fruits, botanically 



speaking, of the latter, which are taken for seeds, 



not the largrt juicy receptacle on the surface of 



which they rest (330). Here the akenes are 



,^_^___^ . . . simple pistils (30.")), very numerous in the same 



]f ^\ /^ flower, and forming a head of such fruits. In 



"' the Nettle, Hemp, (Sec, there is only one pistil to 



each blossom. 



348. In the raspberry and blaekbeny, each grain 

 is a similar pistil, like that of the strawberry in the 

 flower, but ripening into a miniature stone-fruit, or 

 drupe. So that in the strawberry we eat the 

 receptacle, or end of tho flower-slalk ; in the rasp- 

 berry, a cluster of stone-fruits, like chenies on a 

 very small scale ; and in the blackberry, both a juicy 



/^^^""""^---s^ f receptacle and a cluster of i^tonefruits covering it 

 ^ ' (Fig. 289, 200). 



349. The fruit of the Composite family is also 

 an achenium. Here the surface of the ovary is 

 covered by an adherent calyx-tube, as is evident 

 from the position of the corolla, ap|)arently standing 

 on its summit (321, .nd Fig. 220, o). Sometimes the 

 limb or divisions of tiie calyx are entirely wanting, 



as in Mayweed (Fig. 291) and Wiiiteweed. Sometimes the limb 

 of the calyx forms a crown or cup on the top of the achenium, as in 

 Succory (Fig. 292); in Coretipsis, it of>en takes the form of two 

 blunt teeth or scales ; in the Sunflower (Fig. 293), it consists of two
