IXTRODUCTIOX TO BOTAXY. xvii 



for example, convolvulusc 3. rolled back, (revolute.) 4. twisted, 

 (contorted,) the edge of one petal, lying over the next, in an 

 oblique direction ; for example, p£'r/Tw'?/Z-/t', (vinca.) 



II. With respect to margiii, the Cor. maybe — 1. notched, 

 (crenate.) 2. saw-toothed, (serrate.) 3. fringed, (ciliate;) 

 for example, huck-hean, (menyanthes.) 4. toothed, (denti- 

 culate.) 



III. In duration the Cor. maybe — 1. car^ziro?^, falling off 

 as soon as the flower is blown. 2. deciduous^ falling off before 

 the fruit is ripe. 3. i^ersistent, lasting till the fruit is ripe. 

 4. iscithering, (marcescent,) but not falling; for example, the 

 orchis. 



The honey-cup, (or nectary,) is an appendage to the corolla 

 of some plants, for the secretion of honey. It may be a spur, 

 or horn, (see plate, 13-2.) as in the larkspur, snaip-dragon, 

 (antirrhinum,) and columbine, (aquilegia:) a hollow cavity in 

 the substance of the petals, in the crotson-imperial, and croxv- 

 foot, (ranunculus:) in the narcissus it crowns the corolla, like 

 a funnel: in the hee-ophrys, (ophrys apifera,) it is shaped like 

 a bee : it is singularly beautiful in the grass of parnassus, (par- 

 nassia palustris.) 

 N. B. Petals and stamens in plants are ranged alternately : 



but the segments of the calyx and stamens answer to 



each other, in their arrangement. 



III. STAMENS, are slender thread-like substances placed 

 within the blossom, surrounding the pistil, (or pistils.) See 

 Plate, 108, &c. Each stamen is usually made up of 1. the 

 filament,' or thread, supporting the anther. See Plate, 133. 

 a. the filament, h. the anther, and of the anther, or summit, 

 fixed upon the filament, containing the pollen, or anther 

 dust. The pollen is a curious and beautiful microscopic 

 object. 



IV. The PISTIL, is in the centre of the flower, and 

 receives the pollen. This is called the female part of the 

 flower. See Plate, 136. 



The pistil is divided into the (see plate, 136. a.) germen, 

 or lovoest part. 2. the style, (see plate, 136. 6.) which stands 



' Some stamens are without any filament.
