TORENIA FOURNIER! 
S his is a new and an exceedingly beautiful plant, and when tbe length of 
time during which it continues in flower is taken into consideration, it may 
f well be thought worthy of a place in every collection of decorative plants, 
however select such collection may be. 
The plant is of easy culture, and is readily increased by cuttings. Those 
under my care, however, were raised from seed, which was sown in a propagating 
house, about the first week of April last. I think some of them were in bloom 
by the beginning of the following June, and the plants have all continued in 
full flower ever since that time, and are now, nearly the end of October, in great 
beauty, and appear likely to continue so for some time to come. Most of the 
plants are growing in pots some six inches in diameter, and the soil used is the 
same as is generally used for Pelargoniums and other soft-wooded plants. 
But remembering something of the habit of growth assumed by the old 
Torenia asiatica^ a few of them were potted into pots made for the purpose of 
being suspended, and these hung up from the roof of a cool plant-stove, or 
rather an intermediate house, have succeeded well, and are still very beautifully 
in flower. The habit of the plant, however, does not render it quite suited to 
the purpose of being suspended, as it is somewhat erect in its habit of growth, 
and readily forms a dense bush, and does not require much assistance in the form 
of stakes. The flowers bear a considerable resemblance to those of the Torenia 
asiatica^ but they are more beautiful, and are produced in greater abundance. 
To secure the production of seed, it is necessary to have recourse to artificial 
fertilisation.—P. Grieve, Culford. 
GYMNOGRAMMA HEYDERI. 
NEW gold fern raised at Potsdam by Garden-Inspector Lauche, and 
named by him in honour of Councillor Heyder. It is a hybrid raised 
between G. clirysophylla and G. Laucheana^ and is described in the Berlin 
Monatsschrift by Dr. Wittmack. 
The stem is short, clothed with delicate brown chaffy hairs. The fronds are 
long-stalked, the stipes being smooth, shining, dark brown, rounded on the lower, 
channelled on the upper side, furnished with a few frail chaffy hairs at the base, 
and slightly coloured with yellow powder. The blade is triangular-ovate or 
elliptic-oblong in outline, bipinnate; the pinnae oblong-ovate or triangular- 
ovate, and the pinnules broad, the lower ones oblong-ovate, cut into 
crenate-serrate lobes, the upper ones rhomboid-ovate, inciso-crenate-serrate, 
and somewhat convex, dark shining green, the under surface covered with farinose 
powder of a beautiful dark golden yellow. The lines of spore cases are in 
great part overlaid with the golden-yellow dust. 
This fine fern is nearly related to G. Laucheana^ but differs essentially by 
the much broader inciso-crenate-serrate pinnules, which give a more solid 
appearance to the whole frond.
