AMARYLLIDACEyE. 
vittatum are hardy greenhouse plants, requiring absolute rest 
in the winter, and flower freely in the spring ; they grow 
weak in the stove, and will not flower without rest. Solan- 
driflorum and Stylosum are tender stove plants, but should 
rest in winter time. Vittatum is a greenhouse plant requir- 
ing rest in winter, and may be brought into the stove in spring 
to flower it. In Surrey it lived well, flowered yearly, and 
sometimes ripened seed, in the open ground near the south 
front of my house, a small heap of ashes being thrown over 
it in the winter. The mules between Psittacinum and vitta- 
tum would perhaps bear as much exposure, if the wet could 
be kept from them in winter. Reticulatum and striatifolium 
are tender stove plants, and I believe the former is nearly 
lost, and its habitation has never been exactly ascertained. 
Of latter years the striped-leaved variety has been frequently 
sent from Brazil, but the original plant has not been met with. 
The mules between striatifolium, and different varieties of 
bulbulosum, as well as regium and regio-vittatum, have a 
hardier constitution, and many of them come so near to the 
reticulated parents, that they will be preferred in cultivation 
for ornament. Equestrc is a plant of singular constitution, 
and frequently lost in the stoves : though a native of the 
hottest regions of the west, it will not live if watered con- 
stantly in the stove. It requires absolute rest in winter in a 
moderately cool but not damp situation ; it will flower early 
in the summer, and after flowering should be placed in the 
greenhouse, or in the open air, where it will grow better than 
in the stove. Regium requires less care, the stove, and rest 
in winter. The whole family of bulbulosum, except croca- 
tum, are easily managed. By giving them two periods of 
rest, in winter and again at midsummer, they, as well as the 
mules regio-vittatum and rutilo-regio-vittatum, may often 
be made to flower in the spring and autumn. I have found 
great advantage with bulbs that were to stand on a hot flue in 
placing under them a shallow tray made of tin or zinc, and 
nearly filled with sand. In pursuance of this system of en- 
couraging their growth by moist warm sand underneath, a 
gentleman to whom I had given several tender bulbs in- 
formed me that he had constructed a pit for them with a 
chamber into which was introduced a slender steam-pipe, 
perforated with small holes ; and the chamber was covered 
with hurdles, over which he placed a layer of brush-wood, 
and on that a body of sand in which the pots were plunged.
