rogenous plants, scarcely one would have been thought worthy of a 
glance; and the same effect is invariably produced where the collec- 
tion contains a considerable number of species or individuals resem- 
bling each other. The most splendid, however, of the Schenbrunn 
houses is undoubtedly the Aroideous house, as it is called, containing 
an unique collection of Brazilian Aroidew, with other tropical Mono- 
cotyledone ; which, in the low hothouses we are often limited to, would 
give a much better idea of tropical vegetation, than the dwarf and 
stunted specimens of palms in our small collections. These Aroidex 
would also mix admirably with the Orchidacex, the cultivation of 
which is now so much the fashion. 
InTRODUCTION; WHERE GROWN; CuLTURE. The Bignonia venusta 
was first introduced about the year 1817, by Lady Liverpool, who 
received it from Rio Janeiro. It was then expected to prove nearly 
hardy, but not only was this expectation disappointed, but for many 
years it was found so very difficult to flower it, that its cultivation was 
generally abandoned. A few years since, however, the Misses Trevor 
of Tingrith, near Woburn, succeeded in flowering it in great beauty, 
and have done so every year since, from November till February. 
Specimens, exhibited at the Horticultural Society in November, 1835, 
were accompanied by a paper on the mode of treatment, which was 
published in the Horticultural Transactions, (2nd Ser. v. 2, p. 122.) 
Its leading points are these: a perforated board was placed at each 
of the back corners of the bark bed, to keep up a compdést of turfy 
loam, leaf mould, and peat. A plant being put into each corner the 
roots soon penetrated the bark bed, where they were encouraged in 
the growing season by the free use of manured water. When the 
bark was renewed, a considerable space about the roots of the plants 
was left undisturbed. Remaining thus eight years, the plants cover a 
surface of 500 feet, although after flowering they are annually cut back 
to a single stem of six feet. When young shoots are again produced 
these strike root very readily with a little bottom heat. In the Horti- 
cultural Society's garden, where our drawing was taken, it succeeds 
equally well under the same treatment
