XXII.-CLOVEE. 



1. Collect and bring to the class a plant of each of the 

 different kinds of clover that you can find. 



Why is it better for each pupil to collect his own specimens than that 

 another pupil or the teacher should collect the supply for the class ? 



2. How can you distinguish a clover from other kinds 

 of plants ? In answering this question refer to : 



(a) The arrangement and number of the leaflets. 

 {b) The position or arrangement of the flowers. 

 (c) The structure of the flower. 

 {d) The shape of the seed-pod. 



White clover, red clover and Alsike clover are common ; in some locali- 

 ties, to these may be added two yellow hop clovers, rabbit's foot and scarlet 

 clover. 



Many kinds of plants called " clover " are not true clovers. Some of 

 these are the sweet clovers, yellow and white (melilots) ; the round-head 

 and other prairie clovers (kuhnisteras) ; the tick clovers (meibomias or 

 desmodiums) ; the bush clovers (lespedezas) ; sour clover (oxalis) ; black- 

 seed clover (medic). 



3. Describe a clover-leaf under the headings : 



(a) The stem (petiole). 



(b) The leaflets. 



{c) The little wings at the base of the stem (stipules). 



4. Compare the leaf of the common, creeping white 

 clover with that of the red clover. 



5. Compare the stems of the two species. 



6. From the comparison, discover why white clover 

 thrives better in lawns and old pastures than red clover. 



7. Compare the arrangement of the flowers (a head) 

 in the common white clover with that (a raceme) in the 

 white or yellow sweet clover. 



8. Discover the advantage to the white clover of having 

 its flowers in a head. 



9. About how many flowers are in a white clover-head ?
