into a somewhat long or rounded structure such as hangs 

 from the branches of pines. Also the woolly hair (coma) in 

 millet, grass or reeds, such also as many field herbs and rushes 

 in the swamps produce, the Latins call panicula. [Obsolete 

 in this sense. Cf. Panicle.] 



Pappus. Pappus with both Greeks and Latins means the de- 

 ciduous down (lanugo) of flowers and fruits. But it applies 

 also to certain woolly hairs w^hich remain in some plants 

 after the flowers are past and afterwards disappears into the 

 air as in Senecio, Sanchus and other plants. [Cf. Pappus.] 



Pediculus. Pediculus or petiolus is that part by which a leaf, 

 flower, or fruit hangs. [Cf. Pedicle, also Petiole.] 



Pedamenta. Those parts are called pedamenta by which a vine 

 stands erect, i. e., those which it uses as feet. Some even 

 call them pedamina. [Obsolete.] 



Pilula. See Cachr^s. 



Pyramis. See Conus. 



Propago. Propago is an old vine bent down and buried in the 

 earth in the form of arches, so that from one many vines 

 grow. [Cf. Propago.] 



Pulpa. Pulpa in trees corresponds to the muscle of animals. 

 [Obsolete in this sense. Cf. Pulp.] 



Pulvinus. A pulvinus is a small ridge between furrows, so called 

 because it bears a certain resemblance to the saddles in which 

 we sit. [Cf . Pulvinate, Pulvinus.]

The quincuncial figure is half of the figure which to the ancients 

 signified the decussis. The decussis indeed was made in the form 

 of the letter X, which to the Latins meant ten. And if this is 

 cut in half the figure V remains which indicated the number five 

 as well as the quincunx. But if many of these are arranged, 

 some upright, some inverted, they form a figure called quincun- 

 cial. Such clearly the stem of Trichomanes shows. It is fitting 

 to append the printed form of the quincunx and of the quincun- 

 cial arrangement. [Cf. Quincunx.]
