and by some it is likened to a species of orchid-blossoms. 

 It grows freely in shallow warm water, each plant, after 

 separating from its parent, floating, driven about by the 

 winds or currents from one side of the pond or basin to the 

 other. It blooms freely and the very abundant floating 

 roots and inflated petioles or leaf-stalks are very interesting. 



Water Poppy (Limnocharis Humboldtii), Fig. 173. 

 The bright lemon-colored flowers of this little plant add 

 very greatly to the beauty of any collection of aquatics. 

 Plants set out in June grow rapidly and bloom freely. 



Salvinia (S. Braziliensis). A very pretty little float-

 borders of ponds and fountain-basins. It is one of the

 the banks or in the water at the border, and makes a 

 beautiful centre plant for a group of other upland aquatics 

 or in large clusters by itself. 



Variegated Flag (Acorus gramineus var. variegatus). Our 

 native "sweet flag" is familiar to most persons, and this 

 plant is very much like it except that it has most beauti- 

 fully variegated green and white leaves. It is perfectly 

 hardy and grows freely. 



Porcupine Plant (Scirpus Taberncemontani var. zebrina). 

 A beautiful hardy plant with round leafless stems, beauti- 

 fully marked in sections of white and green, giving it some- 

 thing of the appearance of the quills of the porcupine. 

 This plant and the variegated flag can be so grouped with
