This is apparently a natural group ; but the student will be likely to confound it with 

 other groups, unless he pays great attention to its distinctions. In addition to the re- 

 ceptacle rising up more or less between the carpels, so as to make them diverge from each 

 other at the base, it is to be remembered that they fonn only one single whorl, and do 

 not exceed five in number. If this is neglected, they may be confused with some Ro- 

 saceae, Malvaceae, &c. The group is very incomplete, and may be expected to be much 

 altered and increased before its orders are finally settled. 



Rutales connect this with the Syncarpous group through Luvunga, a genus belonging 

 to Aurantiacese. Flb'rkeales distinctly pass into Resales through the genus Florkwi. 

 Geraniales join this to the Parietous group through Violales, and it is probable that Ru- 

 tales also lead to the Calycose group.
