Fig. 



582. — Aponogeton 

 distachyon 



Hawthorn-scented. It prefers 

 a position where there is a 

 gentle current of water, and 

 increases rapidly by means of 

 its tuberous offsets. 



Brasenia peltata {Hydro- 

 peltis purpurea) (American 

 Water Shield) is a handsome 

 little plant with oval - shaped 

 peltate leaves and small pur- 

 plish-coloured flowers. 



Elisma natans (Floating 

 Water Plantain) is a rare British plant, of small and neat habit 

 of growth, and bears showy three petalled white flowers. 



Hottonia palustris (Water Violet) (Fig. 583). — This is one of 

 the most beautiful of our native Aquatics. It has finely pinnate 

 submerged leaves. The scapes rise above the surface of the 

 water to a height 

 of about i2in., and 

 bear whorls of several 

 pretty rosy-lilac 

 coloured flowers. 



Hydrocharis 

 MORSUS-RAN^ (Com- 

 mon Frogbit) (Fig. 

 584). — This elegant 

 little plant has small 

 orbicular or kidnev- 

 shaped leaves and 

 three-petalled white 

 flowers. 



Hydrocleys Com- 

 MERSONi {Limno- 

 charis Hiunboldtii) 

 (the Water Poppy) 

 is a neat-growing, 

 tender Aquatic, and 

 produces pretty pale 

 yellow flowers with 

 great freedom. It 

 is very effective 

 for introducing in 

 shallow water 

 during the summer 

 months, but requires 

 the protection of a 

 greenhouse in the 



winter. Ftg. 583. — Hottonia palustris.
