therefore planted them in pots, and placed them on tan in a 

 pinery, where they soon began to vegetate, and flowered 

 beautifully ; while those which were kept colder did not 

 flower at all. This caused M. Schneevogt to think that this 

 species of Amaryllis does not come direct from the Cape, 

 but is brought from the interior of the country, where the 

 climate is considerably warmer ; and he was confirmed in his 

 opinion by conversing with several of the inhabitants of the 

 Cape, who, upon seeing the figure of the plant which had 

 flowered in Holland, did not remember to have ever seen it 

 before. M. La Brousse, who travelled over a great part 

 of Southern Africa, never saw this plant, until he purchased 

 some bulbs from the CafFres, who informed him that they 

 were found far in the interior. The supply of water given 

 to these plants depends entirely on their growth, and other 

 circumstances; as season, warmth, &c. M. Schneevogt also 

 cultivated several other bulbs from the Cape, as Brunsvig/« 

 falcata, multirlora, &c, in the stove with equal success. 



18. On the Zizania aqudtica. By M. Otto. 



This plant has been cultivated in the botanic garden at 

 Schoneberg, near Berlin, since 1818. The seeds were re- 

 ceived from North America, in a bottle filled with water ; 

 which is the surest way for transporting seeds of bog plants 

 safely. A correspondent of M. Otto made the following 

 remarks on the culture of this plant. If the seeds are dropped 

 into the water of a pond or bog, they will vegetate at the 

 proper season, and their produce will be particularly satis- 

 factory to those who now collect the Glyceria fluitans ; as the 

 grains are not only larger, but they have also more nourishing 

 qualities in them, and have an excellent flavour. They are 

 particularly good to fatten fowls with. Zizania aquatica, or 

 Canada rice, grows in Canada, in boggy places, where it 

 sows itself plentifully (although a great deal is gathered for 

 use), as the least agitation of the stem causes the seeds to 

 fall, even before they appear to be ripe. [Zizania aquatica 

 is successfully cultivated in some British gardens ; as formerly 

 at Sir Joseph Banks's, and now in the Cambridge Botanic 

 Garden. Waterfowl, as ducks, are so very fond of the 

 herbage of this plant, as to render the establishment of it in 

 ponds where ducks visit a matter of difficulty : this was 

 proved in an attempt to establish it a few years ago, in water, 

 on the estate of Lord Calthorpe, at Ampton, near Bury St. 

 Edmunds. — J. D.~\
