TERMINOLOGY. 4S 
15. Flat, (planum), when the foliola of the pe- 
rianth are spread out quite flat. 
16. Doubled or calyculated, (auctum s. calycula- 
tum), when at the base of the common perianth there 
is another row of foliola that appear to form ano- 
ther calyx, as in dandelion, Leontodon Taraxacum, 
fig. 143, 270%. 
The common perianth, (anihodium), is in general 
called by Linnzeus the common calyx, (Calyx com- 
munis ). 
§ 71. 
The foliola which cover the Catkin, § 64, serve 
in place of the calyx; and behind each stand the 
essential parts of the flower, ‘These foliola are 
SCALES, (squame@), fig. 37 T. 
§ 72. | 
The pappus, is a calyx consisting of hairs, or of 
a thin transparent membrane, observed only in par- 
ticular flowers that are contained in a common pe- 
rianth, (anthodium). ‘The pappus remains constantly 
till the ripening of the seed, and we shall consider 
it more fully when treating of the seed, (§ 115). 
Fig. 84, 86, 87. 
* The leaves of the common perianth are called leafets, 
( fohola s. squamae), and in accurate description are denomi- 
nated according to their outline. 
¢ The foliola of the common perianth, of the catkin, of the 
strobilus and other parts, are called likewise sguamae ; but the 
connection always shows distincly of what we are speaking.
