HARPER'S GUIDE TO WILD FLOWERS 

 Ovate. — Egg-shaped. Broader above, tapering below. 



Palmate. — Leaves spreading from the tip of a common stalk. 



Panicle. — A compound flower-cluster, irregularly branching. Grasses and 

 lilies of the valley are examples. 



Papilionaceous (corolla). — The peculiarly shaped flowers of the Pulse 

 family, having standard, wings, and keel. 



Pappus. — The calyx of Composites; the down of thistles and dande- 

 lions. 



Pedicel — The stalk of each flower of a cluster of flowers. 



Peduncle. — The naked stalk of a flower. When flowers are clustered, 

 their common stalk is the common peduncle. 



Perianth. — The floral envelope (sepals and petals) taken collectively. 



Petal. — A division of the corolla. 



Petiole. — The foot-stalk of a leaf. 



Pinnate leaves are compound leaves in which the leaflets are arranged on 

 a common stalk, which answers to the midrib of a simple leaf. 



Pistil. — The central, seed-bearing flower organ, including ovary, style, 

 and stigma, the style not being an essential part. 



Placenta. — That part of the ovary which bears ovules or seeds. 



Raceme. — Numerous flowers on separate pedicels upon an elongated axis. 

 Beneath each flower is, usually, a small bract. 



Rachis. — The principal axis or stem in an elongated spike or cluster of 

 flowers. 



Receptacle. — The tip of the flower-stalk, upon which the floral parts are 

 regularly arranged. 



Rootstock. — A prostrate or underground stem, usually erect at apex, root- 

 ing at nodes or joints. 



Samara. — A winged, indehiscent fruit, as of the maple. 



Scape. — A flower-stalk arising from the root, without true leaves. 



Sepal. — Division of the calyx. 



Serrate. — Like the edge of a saw, teeth pointing forward. 



Serrulate. — Finely toothed. 



Sessile. — Sitting. Of a leaf or flower destitute of stalk. 



Spadix. — A spike of flowers with a fleshy, long axis. 



Spaihe. — A large leaf -like bract, infolding a flower cluster or single 



flower. 

 Spike. — A form of inflorescence in which small flowers, sessile or nearly 



so, are crowded upon an elongated axis. 

 Stamen. — The pollen-bearing organ of the flower, standing next outside 



the pistil, consisting of anther and filament, the latter not always 



present. 

 Standard. — The posterior, large petal of the flower of the Pulse family, 



infolding the others in bud. 

 Stem. — The leaf-bearing part of a plant; erect, prostrate, or subterranean. 

 Stipules. — The appendages which sometimes grow on the opposite sides 



of a leaf, at the base of its petiole. Sometimes they sheathe the
