PTERIS. 
A genus of pretty Ferns, including stove, 
greenhouse, and hardy species. Many of 
them are of elegant habit, and especially 
adapted for decorative use in combination 
with other plants, as also in a cut state for 
mixing with flowers. Variegation of a 
‘decided character is rare among Ferns, but 
it is found in Pteris more distinct than 
in others—for example, the beautiful little 
P. tricolor, with P. Argyrcea and P. cretica 
-albo-lineata.

Ferns, general details of culture.

PTYCHOSPERMA. 
A genus of greenhouse Palms, few in 
number but remarkable for their elegant 
appearance. When they have attained a 
medium size they rank among the most 
stately objects that can be introduced toa 
conservatory ; what is still more in their 
favour is their ability to thrive with much 
less warmth than most Palms. 
For propagation and cultivation, see 
Palms, general details of culture. 
P. Alexandre. A handsome species, in 
either a small or mature state. The leaves 
are pinnate, the pinne droop slightly, 
which combined with the evenly arched 
form of the entire leaf gives the plant a 
plume-like appearance, such as is not 
surpassed by any in cultivation. From 
Queensland. 
P. Cunninghamii (syn: Seaforthiaelegans ). 
In general appearance this is so like P. 
Alexandre that an intimate acquaintance 
with the two plants is necessary to dis-

tinguish one from the other. The young 
leaves of this kind have not the reddish- 
brown tint that is present in P. Alexandree, 
but in other respects they are so near alike 
that it is not necessary to include both in 
the same collection. New Holland. 
P. rupicola. <A stately, distinct-looking 
species, with broad pinnate leaves, the 
pinne much wider than in the last-named 
kinds. <A native of Ceylon. 
PULTENAA. 
An extensive genus of low-growing 
evergreen greenhouse shrubs, with great 
sameness in the flowers, as most of the 
species are yellow. 
They succeed with treatment such as 
given for Boronias, which see. 
The undermentioned are the most de- 
sirable :— 
P. cordata. Flowers yellow, produced 
in spring. <A native of Van Dieman’s 
Land. 
P. elliptica. Yellow ; a spring bloomer. 
From New Holland. 
P. ericoides. Yellow and red; also a 
spring bloomer. Swan River. 
REIDIA GLAUCESCENS. 
An elegant and very singular stove 
plant, with erect habit of growth like that 
of most of the Aralias. In general appear- 
ance the leaves are like those of some of 
the Mimosas. The flowers, which in them- 
selves are insignificant, are produced singly, 
one to each of the leaflets, giving the plant 
a most remarkable appearance. It is best 
adapted for confining to a small state, such 
as in 5 or 6 inch pots, for table decoration. 
It is increased by cuttings, and grown 
on afterwards in the way advised for stove 
Aralias, requiring heat like them, which 
see, A native of Java. 
RESEDA ODORATA. 
(Mignonette. ) 
This fragrant flower is everywhere a 
favourite. 
It is easily raised from seed sown at 
different times in the year, according to 
the season it is wanted to flower. It is 
most acceptable in winter. There are 
different ways of treating it so as to have 
it in bloom during the dull season ; either 
by growing several small plants in 6-inch 
pots or by large examples grown singly in 
good-sized pots, usually described as tree 
Mignonette. To have the latter in good 
condition the seeds should be sown in 
spring, three or four together in 3 or 4
