closely resembles that of the Blackberry. In the Mulberry, however, 

 it is the sepals which become fleshy and sweet. 



The next point is that seeds should be in a spot suitable for their 

 growth. In most cases, the seed lies on the ground, into which it 

 then pushes its little rootlet. In plants, however, which live on trees, 

 the case is not so simple, and we meet some curious contrivances. 

 Thus, the Mistletoe, as we all know, is parasitic on trees. The fruits 

 are eaten by birds, and the droppings often therefore fall on the 

 boughs ; but if the seed was like that of most other plants it would 

 soon fall to the ground, and consequently perish. Almost alone 

 among English plants it is extremely sticky, and thus adheres to the 

 bark. 



I have already alluded to an allied genus, ArceufJiohium, parasitic 

 on Junipers, which throws its seeds to a distance of several feet. 

 These also are very viscid, or, to speak more correctly, are embedded

in a very viscid mucilage, so that if they come in contact with the 

 bark of a neighbouring tree they stick to it. 



Another very interesting genus, again of the same family, 



IS
