THE GARDENING WORLD . 7,1904. 
Tomatos over a newly-made hotbed. Should you have any 
doubt about it, leave a chink of air at the top end of the sash 
until tlie bed lias cooled down sufficiently to be safe. 
Long Hair-like Worm. 
I found a specimen of what is known as the hair worn on the 
bench of one of our plant houses. Does it do any harm to 
plants like the eelworms? I should be much obliged for any 
information on the subject. (G. Wakd.) 
The presence of the worm in one of your houses may be 
regarded as accidental. It is known as Gordius aquaticuis, and is 
generally regarded as harmless to plants. They are not, as a 
rule, very plentiful, and are most frequently met with during 
drizzling and wet weather. As the specific name implies, it 
requires plenty of moisture, and without that it would.soon coil 
itself up and become inactive if it did not die outright. You 
can merely throw it outside or destroy it as you like, but we do 
not think there is- any necessity for being alarmed at its presence. 
Gold-laced Polyanthus. 
I should be pleased to have your opinion upon the Polyanthus 
enclosed. (Quo.) 
The rich crimson colour of the flower is very good, but the 
gold lacing is not complete. This should run round each lobe 
forming a complete line. The yellow should not run into the 
crimson, nor vice versa, but both should have a clear and distinct 
outline. For ordinary garden decoration, however, the variety 
is beautiful and quite sufficiently ornamental to be worthy of 
preservation, or even for extended cultivation in borders and 
the margin of shrubberies. As a show flower it would not, how¬ 
ever, be regarded as sufficiently meritorious to take its place in a 
stand of gold-laced Polyanthus. 
Brown Patches on the Leaves of Gloxinias. 
Can you say what is the matter with the leaves of Gloxinias 
enclosed ? They went the same way last year and did not 
flower well. Please say what is the cause, and whether they can 
be checked. (D. R.) 
lire leaves have been attacked by a small mite which is 
usually without colour and difficult to detect by the naked eye. 
It is very common in hothouses, however, especially those that 
are kept too dry, and often does damage to many other plants 
besides Gloxinias. You should make up a strong solution of 
soft soap or Gislrurst Compound in warm water and thoroughly 
syringe the leaves with tipis. You will have to be particularly 
careful that the underside of the leaves is syringed so that 
every part may be thoroughly wetted with the liquid. You 
could do this by employing a boy to hold the plants while you 
*f l iu g e the leaves on the under side. You will, of course, have 
to ba particularly careful not to break the leaves by the opera¬ 
tion, otherwise you will lose the good results of your labours. 
he house should be closed at night and every part thoroughly 
damped down so as to create a steamy vapour in the house, 
tins may be done on several successive nights—that is, the 
damping down—and the nrito will get thoroughly eradicated 
while the plants will yet regain their vigour and flower well

Ihe specimens you sent appear to be Acer Ginnala, but the 
flowers you sent are not half expanded. The flower stalks get 
much longer and hang down. The trees about London will 
be m lull leaf m a few days, and the flowers have been in bloom 
for some time. Yours are scarcely far enough advanced to 
furnish evidence. We should be pleased if you would send 
leaves when fully advanced, though we think the leaves you 
sent last autumn were conclusive enough. The tree makes a, 
jeautiful bushy specimen in the south, but the temperature with 
?nV S r< a tl w, u , t0 ° low for Japanese and similar Maples.— 
(C. B Green) The specimen with the dense arrangement of leaves 
was Prunus spinosa (the Sloe); the other one appears to be 
the Dullace (P. msititia), but it should be in full leaf to make 
certain. It should have the last year’s shoots brown, with a 
tew spines on the tree, downy and larger leaves than the Sloe, 
but the two trees have many intermediate links —(J R ) l
