Gros Colmar Grape - T. Pdi: We can only suggest that the 
leaves of this variety being more downy than the others, were 
loDger in getting rid of the condensed moisture on them one 
fine morning, and so were scalded by the action of the bright 
sunshine. The injury cannot he .the result of any defective root 
action, as while the parenchyma of the leaves is entirely 
destroyed, the principal veins are still perfectly green, nor can 
the tobacco smoke be held responsible. 
Hsemanthus Katherine.—/. F. A.: This species is considered 
one of the finest and most easily cultivated of the genus. 
It is a native of Natal. The reason why it does not 
flower with you must either he that the bulbs are too small, or 
it is due to some fault in the method of cultivation. When 
developing its foliage the latter should be well exposed to light 
and fairly freely ventilated during fine weather. Encourage 
growth as much as possible at the right season, and when the 
foliage begins to decay, ripen off the bulbs gradually in a freely- 
ventilated pit or frame. Allow them to rest for some time by 
keeping them dry. Re-pot if necessary when the bulbs show 
signs of starting. 
Masdevallia rosea.— 7. F. A.: There is always a difficulty in 
getting this species to open its flowers properly, for in nine cases 
out often, the flowers exhibit the crumpled peculiarity .of t hat, 
you sent us. In fact the flowers very rarely if ever expand 
properly, judging from the specimens we have s&en in many 
diflerent establishments. The species comes from very high 
elevations in its native country, and is generally grown in a cool 
house, hut perhaps more often with the Cattleyas. We recently 
saw it flowering finely in a Cattleya house, hut the flowers were 
crumpled much as usual. There were some thrips and green-fly 
about the specimen sent. It is more than probable that they 
augment the evil. Keep the plants clean if possible, and even 
if the flowers are somewhat crumpled they are no worse than 
what occurs in other collections. 
Names of Plants.— Roseburgh: The tree is Crataegus punc¬ 
tata ; the herb is Cocblearia officinalis, or some variety of it, to 
determine which we should require a specimen in fruit. Please 
send radical leaves as well. S,. K. G.: 1, Thalictrum aquilegi- 
folium ; 2, Thalictrum sp. unrecognised ; 3, Thalictrum minus ; 
4, Euphorbia sp. (comes near E. palustris); 5, Viburnumlantana; 
6, Iris graminea; 7, Valeriana alliaritefolia; S, Rhinanthus 
Crista-^alli. R.H.: Hemeroeallis flava. II. Pollard: Achillea 
mongolica. W. G. Balxr: Epidendrum fragrans : the Labiate is 
Calamintha grandifloia. Josef Stjkora: 1, Nephrodium decompo¬ 
sition glabellum ; 2, Nephrodium decompositum; 3, Polypodium 
Lingua; 4, Asplenium viviparum; 5, Adiantuin Ghiesbreghtii 
var°apparently, hut specimen imperfect; 6, Asplenium rnacro- 
carpum apparently, hut you should send a fruiting specimen. 
Odontoglossum crispum. —7. Coclxr: The flower you sent is 
that of a good variety, which may even improve when the plant 
gets thoroughly established—that is, the breadth of-the -sepals 
and petals may be such as to cause them to overlap to a greater 
extent. We do not expect that there will be much if any alter¬ 
ation of colour ; but that, as far as it goes, is good enough for 
decorative purposes, and would even be worthy of being included 
in a collection of good kinds. 
Peach leaves injured,—Mr Anxious Gardener: The leaves 
are very poor and thin in texture, and have been unable to stand 
bright sunshine coming after a dull cloudy period, hence the 
scalding. Give more air, and earlier in the day, and see that the 
roots do not want for nourishment. 
Plum Trees Unfruitful— N. II. F. : There must be some 
other local eircumstar ces than the waut of lime in the soil to 
account for the constant failure of the trees to fruit, and which 
only those on the spot can determine. You would do well to 
consult a local gardener or nurseryman, who is familiar with the 
district. 
Quassia Mixture. — W. G.: Boil 4 ozs. of quassia chips for 
ten minutes in a gallon of soft-water ; strain off the chips and 
add 4 ozsl of soft-soap, stirring up well until the latter is dis¬ 
solved. - Use when cool, keeping ifc-well stirre<L-up, and syringe 
with clear water ten minutes afterwards.

“Dear Sirs —I have thoroughly tested a sample of a new 
Insecticide which you were so good as to send me. At the 
rate of 1 oz. to a gallon of water at a temperature of 95° I find it 
kills Green-fly immediately. Double this strength, or 2 ozs. to 
gallon at 120°, seals the fate of Scale of all sorts in a few seconds ; 
while 3 ozs. to gallon at same temperature effectually dissolves 
Mealy Bug,, and so far as I have yet observed, without the 
slightest injury to leaf or flower, and it is withal a most agree¬ 
able compound to work with. All our insect remedies are 
applied through common syringe or garden engine, a much 
severer test of efficiency than when applied by hand-washing or 
spray.
