of their axes, leaving merely the four cotyledons sepa- 
rate. A similar adnation has been observed by the 
same botanist in Lepidiwm sativum and Sinapis ramosa, 
as well as in other plants.’ [ have met with correspond- 
ing instances in Antirrhinwn majus and in Crategus 
oxyacantha, in the latter case complicated with the 
partial atrophy of one of the four cotyledons. It is 
necessary to distinguish between such cases and the 
fallacious appearances arising from a division of the 
cotyledons. M. Morren has figured and described the 
union of two roots of carrot (Daucus), which were also 
spirally twisted. He attributes this union to the 
blending of two radicles, and apples the term “ rhizo- 
collesy” to this union of the roots.” Mr. Thwaites cites 
a case wherein two embryos were contained in one seed 
in a Fuchsia, and had become adherent. What is still 
more remarkable, the two embryos were different, 
a circumstance attributable to their hybrid origin, 
the seed containing them bemg the result of the ferti- 
lisation of Huchsia coccinea (quere I’. magellanica ?) by 
the pollen of F. fulgens.
