GLOSSARY. 189 
Papilionaceous. The sweet-pea type of flower. 
Pappus. The plume of a Composite akene (dandelion etc.). 
Parted. More deeply divided than lobed, but not compound, as 
applied to leaves. 
Pedicel. The stalk of a flower in a compound inflorescence. 
Peeling. Much the same as flaking or shredding. 
Pellucid-dotted or glandular. Applied to leaves etc. which con- 
tain internal oil-glands (orange, wafer-ash, etc.). 
Peltate. Attached to a stalk at some distance from the margin, 
like the leaf of an Egyptian “lotus”, the scales on leaves of 
the Russian “olive,” etc. 
Pendent. Hanging, like the cone of spruce: that of fir is erect. 
Percurrent. With the main trunk continued through the top, 
hence usually conical or spire-like (spruce), as applied to 
trees: in extreme contrast with deliquescent. 
Perennials. Plants that live for a number of years. 
Perfect. With both stamens and pistil, as applied to flowers. 
Pericarp. The outer part of the fruit. 
Perigynous. With sepals, petals and stamens around the edge 
of a cup surrounding but free from the pistil or pistils, as in 
the cherry and rose: contrasted with epigynous and hy- 
pogynous. 
Persistent. Not deciduous, as applied to leaves. 
Petals. The inner floral leaves, forming the corolla. 
Petiole. The leaf-stalk. 
Phanerogams. Flowering- or seed-plants. 
Phylloid shoots. The foliage of pines; morphologically con- 
sidered as modified branches of the stem, rather than leaves. 
Phylum. The same as division. 
Pinnate. Distributed along an axis, like the plume of a feather 
on the quill (leaflets of an elder leaf, the lobes or veins of 
an oak leaf, etc.). When unqualified it means pinnately 
compound, if applied to leaves. When the leaflets of a pin- 
nate leaf are again pinnate, the leaf is bipinnate or twice 
pinnate. Unequally pinnate or bipinnate leaves vary greatly 
in their compoundness, often in the same leaf (honey 
locust).
