BOTANICAL APHORISMS. 167 
aways corresponds with the style; if there is but 
one pistillum, the fruit is unilocular; if there are 
more, there are also cells in the pericarp. 
The form of the calyx in general isa cup with 
erect foliola; the flower is commonly more or less 
funnel-shaped ; the stamina pointed ; the pistillum is 
- furnished with a slender and pointed style with a 
simple stigma. 
With regard to proportion, the calyx is often 
about a third shorter than the corolla; the stamina 
and style are hardly longer than the calyx. As to 
situation, the calyx incloses the corolla and the pe- 
tals are alternate with the foliola of the calyx. The 
stamina stand opposite to those foliola. ‘The pistil- 
lum stands on the top of the germen. The seeds 
rest on the receptacle. 
In a natural structure it is further observable, that 
a monopetalous corolla has a monophyllous calyx, 
and that a polypetalous corolla has a polyphyllous 
calyx. The coroila and calyx are seated on the re- 
ceptacle. In a polypetalous corolla the stamina 
stand upon the receptacle; in a monopetalous, they 
are inserted in the corolla itself, 
This natural character ought never to enter into 
descriptions. It would, for example, in the natu- 
ral character of the Solanum, (§ 148), be quite 
superfluous, to say, Calyx corolla minor, viridis, folia- 
ceus, corolla tenera, anthere pulvere flavo farcta, ger- 
men post florescentiam intumescens, %Jc.; because all 
these circumstances are supposed ina natural de- 
scription, where we expect to find only discrimins 
ating characters. |
