THE ROSE TRIBE. Ill 



Stems covered with hard hooked prickles ; in this re- 

 spect they differ from the Strawberry. Their leaves 

 are divided, in various ways, according- to their 

 kinds, and have large stipules at the bottom of their 

 stalks ; here they agree with it. Their calyx has 

 only five divisions instead of ten ; which is a difi*e- 

 rence ; but their petals are five ; the stamens nume- 

 rous, and arising out of the side of the calyx ; and 

 their pistil composed of a number of carpels arising 

 out of a central receptacle ; these, again, are resem- 

 blances with the Strawberry in important points. 

 Let us examine the fruit. The Raspberry has a dry 

 core, off which you may pull the little thimble-like 

 fruit, and you will not find any of the dry grains which 

 stick upon the outside of the Strawberry. But, look 

 again ; what are the little dry threads that you see 

 rising from the centre of a multitude of little projec- 

 tions with which the whole surface of the Raspberry 

 is covered ? Surely they are styles ; and, if so, the 

 projections out of which they grow, must be carpels 

 in a ripe state. This is really the case ; the carpels 

 of the Raspberry, instead of remaining dry as they 

 become ripe, swell and acquire a soft pulpy coat, 

 which, in time, becomes red : they are crowded so 

 closely, that, by degrees, they press upon each other, 

 and, at last, all grow together into the thimble-shaped 

 part which you eat ; in order to gain this succulent 

 state, they are forced to rob the receptacle of all its 

 juice, and, in the end, separate from it, so that when 

 you gather the Raspberry, you throw away the re- 

 ceptacle under the name of core, never suspecting
