- r >78 APPENDIX ON THE CLASSIFICATION OF PLANTS. 



KOBERT BROWN published in 1827 his discovery of the gymno- 

 spermy of the ovules of the Coniferse and Cycadeas, and showed 

 that the Gymnosperms, which had previously been classed with 

 the Dicotyledons, must be regarded as an independent group.
