162 GLOSSARY. 



caryophyllaceous, five long-clawed petals with spreading laminae; 

 rosaceous, five short-clawed petals, spreading; 

 liliaceous, six perianth-leaves, gradually spreading; 

 papilionaceous, page 69; 

 orchidaceous, page 40. 



b. the parts more or less united; 

 cup-shaped, tube very short and border concave; 

 wheel- or- star-shaped (rotate), tube very short and border flat; 

 urn-shaped (urceolate), oblong or globular, border contracted; 

 bell- shaped (campanulate) , tube with rounded base, border spreading; 

 salver-form, tube narrow, abruptly passing into a spreading border; 

 funnel-form, tube narrow, gradually widening into a border; 

 tubular, tube narrow with a small border or rim; 



strap-shaped (ligulate), tube as if split open lengthwise and flattened, border repre- 

 sented by teeth; 



lip-shaped (labiate), tube widening and ending in a 2-lipped border; the corolla 

 has a 2-lobed upper lip and 3-lobed lower lip; if the calyx is also labiate 

 the position of the lips is reversed. — A labiate corolla is galeate when the 

 upper lip is concave (helmeted); it is personate when the juncture of tube 

 and border (called the throat) is narrowed by a palate; it is ringent or gaping 

 when the throat is wide open. 



Pericarp: the wall of the fruit, sometimes the whole fruit. 



Petals: parts of the Corolla. 



Petiole: leaf -stalk. 



Phyllodium: a leaf with flat, expanded petiole and no blade. 



Pistil: a leafy structure of the Angiosperms, composed of: 



the ovary, which consists of one or more carpels containing the ovules or 



megasporangia, 

 the style or styles, which may be absent, and 

 the stigma, the receptive surface for the pollen; it is called sessile when the 



style is absent. Styles and stigmas may be more or less united. 

 The ovary is simple, — or compound, i. e. containing one or more cells or 

 locules, — or multiple, when several simple ovaries are united. As to 

 position, the ovary may be superior (jree from the calyx), when perianth 

 and stamens are inserted below, — or inferior (adnate to the calyx), 

 when those other parts of the flower are inserted above the ovary. 



Placenta: the place within the ovary-cell where the ovules are attached. — Placentae 

 may be sutural or ventral, — axial or central in some 1-celled compound 

 ovaries, — or parietal, i. e. on the wall of the cavity. 



Pollinia: masses of coherent pollen. 



Pollen: (see Stamen). 



Praemorse: as if bitten off. 



Punctate: marked with pits, translucent glands, or colored dots. 



Pungent: sharp to taste or smell. 



Putamen: the shell of a nut; also the stone of a fruit. 



Rachis: the axis of an inflorescence; also the main-rib of a frond, or of a compound 

 leaf. 



Raphe: (See Ovules). 



Receptacle: (see Torus). 



Reticulate: netted. 



Rhizome or Root-stock: a fleshy rooting stem, wholly or partially underground, often
