54. The first genus mention- 
ed is, ‘‘Hypraneza;” this is 
said to have a “calyx 5 tooth- 
ed, superior,” examine the 
iy calyx of the pink (Fig. 5, a ;) 
j this is five toothed, or has five 
jj notches around the top of it; 
f but it is not superior, that is, 
the calyx does not stand above 
the germ. Your flower is not 
therefore of the genus Hydran- 
gea, because it does not fully 
agree with the description.

55. Saxirraca. “Calyx 5 parted, half superior ;” although 
the first part of this description agrees with your flower, the 
last part does not correspond with it. 
56. Saponarnita. “ Calyx inferior” (under the germ,) “1 
leafed,” (all of one piece;) “tubular,” (long and hollow like a 
tube,) “5 toothed ;” so far this description applies to your flow- 
er.—But the next circumstance, “calyx without scales,” is dif- 
ferent from what you see in the pink, (See Fig. 5. 0.* K 
57. “Dianruus. Calyx inferior, cylindrical’ (long and) 
roundish ;) “1 leafed, with 4 or 8 scales at the base; petals 5,” 
(See Fig. 4. a) “with claws,” (the petals long and slender at 
the lower part;) “capsule” cylindrical, 1 celled (the capsule 
is a kind of pericarp;) “ dehiscent,” this means gaping, as you. 
see at Fig. 5. c, which represents the capsule or seed vessel of 
the pink as it appears when ripe, the valves or pieces which — 
At d the capsule appears as if cut horizontally, showing the 
seeds all contained in one cell. Fig. 4 at c shows the capsule 
as it appears when the pink is in blossom, at which time it is 
called the germ. As this flower agrees in every particular 
with the last mentioned description, you may be certain ycu 
have now found its genus; the pink then belongs to the genus 
DiaNTHUs. 
* This represents the scales of the calyx of the pink. e 
55. Why is it not of the genus Sazifruga? 
56. Why is it not Saponaria ? : 
57. Why is the pink of the genus Dianthus ?

compose it, open of themselves as if for liberating the seeds. —
