in the Castor-oil plant. 



Palmate-lobed, palmate with rounded lobes, as in the leaves of the Maple. 

 Palmatisect, palmate, with the divisions extending to the bottom of the leaf, as 



in the leaves of Potentilla reptans. 

 Panicle, a raceme with branching pedicels. 

 Papilionaceous, like the flower of a Pea. 

 Pappus, the crest of the fruit in Composites, formed of the altered limb of the 



calyx.

 Pectinate, scalloped, crenately incised. 

 Pedate, palmate with three lobes and the lateral lobes having similar large lobes 



on their outer edge, as the leaves of Helleborus.

 Pedatifid, pedate, with the divisions reaching to the middle of the leaf. 

 Pedatisect, pedate, with the divisions extending nearly to the midrib.

Pedicel, the branch of a peduncle. 

 Peduncle, flowerstalk. 

 Peltate, when its point of attachment is on the face, not at the edge, of a leaf or 



other organ. 



Pentagonal, with five angles having convex spaces between them. 

 Pentangular, with five angles and five flat or concave faces. 

 Perfoliate, when the leaf completely surrounds the stem so that the latter seems

 Pericarp, seed-vessel, including adhering calyx if present. 

 Persistent, not soon falling off. 

 Personate, a monopetalous two-lipped corolla of which the lower lip is pressed
