trees, but on dead branches, on bricks, tiles, stones, the ground, 

 &c. But, though they germinated in sucli situations, they did 

 not Hve any time, except on tlie bark of Hving trees. M. Du 

 Trochet made seeds of the mistletoe germinate on the two sides 

 of the frame of a window, and in both cases the radicles 

 directed themselves towards the interior of the room, as if in 

 quest of darkness. (See Richard's Elements of Botany; and 

 Baxter's Brit. FluxGering Plants, art. Viscum.) Tiie first indi- 

 cation of germination is the appearance of one or more radicles, 

 like the sucker of a house-fly, but larger; as at h i \Vi fg. 80.,

 mistletoe berries, 

 which were stuck 

 on the upright trunk 

 of a cherry tree in 

 our garden at Ba^^s- 

 water, in March, 

 1836, and germi- 

 nated there, as they 

 appeared on the 

 20th of May of the 

 same year. When 

 the white, viscous, 

 })ulpy matter of the 

 mistletoe berry is re- 

 moved, tiie kernel, 

 or seed, appears of 



a greenish colour, and flat; sometimes oval, at other times 

 angular, and at other times of various forms. In Jig. 80., a is

 showing the two embryos ; g, the embryo magnified ; /;, the two 

 embryos, with the two radicles germinating; ?', a single radicle ;

" It is remarked by Du Hamel, that, when the form of the seed 

 is oval, generally one radicle only is protruded ; but, when it is 

 trfangular or irregular, 2, 3, or more, appear. It is singular, that, 

 while the radicle of almost all other plants descends, this is not 

 the case with the misdetoe; the young root of which at first 

 rises up, and then bends over till it reaches the body of the 

 substance to which the seed has been attached, as at /(-.and /, 

 in fig. 80. Having reached that substance, the point of the radicle
