July, 1845, without any name, but was recommended to be 
grow r n as a curious and very beautiful plant. About November 
some of the plants began to show flower, and in December 
damped off; the later plants kept better, and were planted in 
the open ground in May, where they have been in flower ever 
since. I am not able to say whether the plant is an annual or 
a perennial. Three plants are now breaking up again from the 
bottom, but one very strong, twenty inches in height, and 
which has had upwards of twenty spikes of bloom, is not yet 
breaking up. I have not found it seed at all without being set, 
when it seeds in abundance ; it may also be increased by cuttings, 
but is hardly worth the trouble, as one good pod contains 
four or five hundred seeds. As far as I have been able to judge 
of its culture, I should recommend seed to be sown about the 
middle or end of August, and when the plants are large enough 
to be potted off, kept in a very airy pit or greenhouse during 
winter. I have reason to believe a few degrees of frost will not 
be injurious to it. I fear its greatest enemy will be the short 
dull days of the winter months. If seeds are sown in a gentle 
heat in February, I think the plants would be in bloom by July. 
The soil in which I have grown it in pots is sandy peat and 
loam, but in the open ground it is planted in the common soil, 
which is light and sandy.

Brassicace^e .—Tetr adynamia Siliquosa. 
Heliopliila trifida, (Thunb.) A very pretty, half-hardy annual, 
requiring to be grown in a mixture of sandy peat and loam, to 
which should be added a small portion of well-decomposed leaf- 
mould or rotten dung. The seed should be sown about the end 
of February, in pots, and raised in a close pit or greenhouse, and 
treated like other half-hardy annuals. When the plants are 
sufficiently large, they should be transferred to other pots, not 
more than three or four plants being placed in each pot. It 
produces its gay ultramarine blue flowers from June to September, 
in the greenhouse, and grows about a foot high. In a natural
