ten inches diameter, and the leaves fifty-six inches across, with stalks i 

 forty to sixty inches. Euryale ferox, although flourishing in the 

 winter in the Nympha3a house, was removed, for want of space, to the 

 lily pond in the early part of the year, where it did exceedingly well, 

 and produced fifty flowers and seventy leaves, with a diameter of forty- ' 

 five inches. 



In the Victoria Regia House are amongst others the following | 

 aquatics, including fine specimens of all the Nymphaeas before men- 

 tioned in the lily lake: Acrosticthum aureum (West Indies), Cahomha 

 caroliniana (U.S.A.), Ceratopteris thalictroides of the tropics ; Canna 

 flaccida; several fine species of Cyperus from Australia and Jamaica, 

 including the Egyptian, C. Papyrus ; the beautiful Eichhornia {Ponte- , 

 deria) crassipes of Guiana, whose vigorous growth became a- serious , 

 impediment to the rivers in Florida, when introduced there some years | 

 ago, Eichhornia azurea and E. cordata; Hydrocotyle Bonarenensis, I 

 Limnanthemum Henkei; Cryptocoryne Becketii (East Indies), Trig- \ 

 lochin maritimum of Britain; Pilularia globulifera; Sagittaria graviinea \ 

 (North America) ; the curious Marsilea Drummondii, resembling a four- | 

 leaved shamrock; fine specimens of Saccharum officinarum and S. ! 

 ofjicinarum atropurpureum ; the two Thalias, dealbata and divaricata; | 

 Limnocharis emarginata from the tropical regions of America ; Myrio- j 

 phylluni affine and Ludwigia alternifolia and L. hirsuta.^ !

 coerulea grandiflora, P. coerulea racemosa, P. alba, P. adenopoda, P. 

 ' Constance Elliott,' P. cardinalis, P. kermesina, and the most beauti- I 

 ful of all Passifiorae, Tacsonia Van Volxemii; the curious Hexacentris | 

 mysorensis, and Rivea hypocrateriformis, whose large white moonlike j 

 flowers as they open suddenly at sunset are the great beauty of I 

 the tropics. Vanilla aromatica is a flourishing plant, as is Schubertia -^^^^
