GLOSSARY 



Sepals. These are the outermost. They 

 are usually green in color, but small. 

 All together, they make up the calyx. 



Petals. These are inside the calyx. They 

 are usually larger than the sepals and 

 showy in form or color. The petals 

 make up the corolla. 



Stamens. These are borne in or upon the 

 corolla. Each stamen is made up of a 

 slender stalk, called the filament, and 

 an enlarged end, usually yellow, called 

 the anther. The anther is full of a fine 

 powder called pollen. 



Carpels. These are the central leaves of 

 the flower, but usually do not look at 

 all like leaves. A flower may have one 

 or more of them. Any one carpel not 

 united with others, or a union of several 

 of them, makes a pistil. A flower of 

 most kinds of plants has but one pistil; 

 but a few kinds, as the ilangilang and 

 atis, have many. The parts of the pistil 

 are: I. The enlarged, hollow, basal 

 part, the ovary, which contains ovules. 

 2. The upper part, the stigma, on 

 which the pollen must fall and germi- 

 nate. 3. The style, which connects 

 the ovary and stigma. Some flowers 

 have no style. Pistillate flowers con- 

 tain pistils but 'no stamens. Staminate 

 flowers have stamens, but no pistils. 

 Flowers with both stamens and pistils 

 are perfect. 



Germination. The beginning to grow of 

 a seed or spore. 



Hybrid. A plant or animal whose parents 

 are of different kinds. The mule is a 

 hybrid between the horse and the 

 ass. 



Induction coil. An apparatus for produc- 

 ing electric currents by induction. In- 

 duction is the causing of a current in 



. one body by a current in another body, 

 when the two bodies are not in contact. 

 In induction coils the wires are usually 

 wound with silk, to keep them from 

 touching each other. 



Inflorescence. A collection of flowers 

 growing on a special part of a plant. 

 All the flowers on an ear of maize, or 

 at the top of one stem of tobacco or 

 rice, make up an inflorescence. 



Internal revenue. All the revenue or 

 income of a country, except that col- 

 lected by taxes on exports or im- 

 ports. 



Litmus paper. Paper treated with a sub- 

 stance which makes it blue when alka- 

 line, but red when acid. An acid is a 

 sour substance^ such as vinegar. Lime 

 and ashes are alkaline. 



Node. The part of a stem where leaves 

 and branches are borne. 



Panicle. A branched inflorescence, in 



which the lower flowers blossom before 



those at the top. 

 Parasite. Any living thing which gets 



its food from some other living (not 



dead) thing. 

 Petal. See Flower. 

 Petiole. The part of the leaf which is 



stem-like. A leaf without a petiole is 



sessile. 



Pistil. See Flower. 

 Pollen. See Flower. 

 Propagation. See Reproduction. 

 Proteids. Food substances which are
