sets respectively. As examples of tlie first four kinds, may be 
mentioned tbe mallow, pea,, common bypericum, and the tutsan 
liypericum. 
The word syngenesious is to be used with all Composite, 
Lobeliaceae, &c., where the anthers cohere but not the filaments. 
In the last (uppermost) space devoted to “ pistil, carpels,” 
the words apocarpous and syncarpous are to be inserted, 
according as the pistil consists of one, or more than one, free 
carpel; or, when there are two or more cohering carpels. The 
pea, ranunculus, and rose, are instances of the first ; the 
wall-flower, mallow, and tulip, examples of the second case. 
Returning to our Wall-flower, the first two columns will now 
stand thus : — 
The fourth column is 
headed “ Adhesion,” in 
reference to the fact that 
different whorls are fre- 
quently combined, or “ad- 
here” together. Thus, 
in all species of the Ro- 
sacese, the stamens and 
petals will be found ad- 
hering to the calyx, and 
in the Compositse, Umbelliferae, &c., the calyx, corolla, and 
stamens are all adherent to the ovary. 
We subjoin a brief description of the terms to be employed 
in this column : — 
/If the calyx, or Monochlamydeous * perianth do not adhere 
\ to the ovary, the calyx is Inferior and the ovary Superior. 
\ If they adhere, the ovary is considered to he Inferior and 
I the calyx Superior, the free portions of which, when 
v present, appear as if inserted upon the ovary. 
\ Not adhering to the calyx or ovary, but inserted ' 
) immediately on the floral receptacle. 
/ Adhering partially to the calyx, or to a Mono- 
chlamydeous perianth, the free portions 
( appearing as if inserted upon it. 
j Adhering partially to the ovary, the free por- 
) tions appearing as if inserted upon it. 
j Stamens adhering partly to the corolla, their free portions 
l appearing as if inserted upon it. 
/ Stamens adhering to both ovaiy and style, so that a central 
) column is formed by them, upon which both anthers and 
( stigmas are seated. As e. g. in the order Orchidacese. 
* The word “ Monochlamydeous ” signifies having only one floral envelope.
