near the glass in an East Indian house and kept moist they will 
flower regu'arly every year in April or May.—C. K. 
Warscewiczellas. 
The genus Warscewiczella was founded by Reichenbach, but 
is now included under Zygopetalum. Warscewiczellas differ from 
the original Zygopetalums in having no pseudo-bulbs and in bear¬ 
ing solitary flowers. There are about eight species, the leaves 
erect and growing in tufts. Being natives of Central and Southern 
America they require a fairly high temperature to grow in, as well 
as a very moist atmosphere. The plants should be placed in 
shallow pans nearly full of crocks with sphagnum over the long 
fleshy roots ; if kept moist the roots will grow rapidly, clinging to 
the crocks and sides of the pan. Warscewiczellas are difiicult 
plants to grow well, and unless very carefully treated in the matter 
of moisture the leaves will spot and sometimes fall off without any 
warning. The coolest end of the East Indian house suits them, if 
well shaded. The flowers are large and fragrant, the colours are 
bright, the large lip is folded at the sides in a curious manner. 
The following are about the best known :— 
W. aromatica.—Flowers fragrant, sometimes 4 inches across, 
dnll white, lip deep purple with crisped margin, leaves erect : 
Brazil. 
W. Candida. — Flowers white, lip rosy purple with paler 
margin, disc white marked with purple, leaves about 8 inches high ; 
Bahia. 
W. discolor.—Flowers yellowish green, shaded purple, lip a 
velvety purple, white at the base, with a crest of several teeth. 
W. marginata.—Large circular yellowish green lip, yellow claw 
and white column ; leaves dwarf. 
W. picta.—Lip white shaded yellow, purple markings, sepals 
green, and several green teeth at the base of the lip. 
W. velata.—Flowers very fragrant, sepals and petals greenish 
white, lip edged with crimson, disc striped with crimson, a half 
circle of long teeth at the base of the lip, leaves 9 inches long. 
Introduced from New Grenada in 18G6 ; it is one of the prettiest. 
W. Wailesianum.—Yery sweet scented, sepals and petals creamy 
white, lip white veined with violet at the centre, teeth violet ; 
Brazil. 
\Y. TYendlandi.—This species has very large flowers sometimes 
5 inches across, sepals and petals white, twisted, lip white veined 
with purple, margin crisped, several violet teeth at the base of the 
lip ; Costa Rica. 
W. Wendlandi discolor.—Scented sepals and petals, yellow 
green, lip white violet, blotched, margin finely crisped ; Costa 
Rica. 
W. Lindeni (fig. 79, see page 461) a charming form, having a 
very broad flattened lip, pure white, lined with purplish mauve, 
sepals and petals white. It was exhibited by L’Horticulture 
Internationale at the last meeting of the Royal Horticultural 
Society and received a first-class certificate.—C. K.

There can, I think, be no question about the wisdom of the 
judicious feeding of terrestrial Orchids, providing other conditions 
are favourable. These plants are certainly improved by it, and larger 
pseudo-bulbs, with bolder spikes of flowers, result. If the latter 
were not the case the large growth would not be sufficient to tempt 
us to carry on the practice. In the case of Dendrobes, Cattleyas, 
and others I believe it possible to produce larger growths by the aid 
of feeding, but they have not flowered better or produced finer 
blooms ; in fact, from the limited experiments made, I am not 
warranted in recommending the practice. It is not impossible to 
produce larger growths than by ordinary treatment, but after the 
resting period the plants do not appear to be in such good condition 
as those that have had what to my mind is more rational treatment. 
I have concluded that extra size has been developed at the expense 
of solidity, the cells being stored with water instead of the nutrient 
matter so essential for sustaining the plant throughout the exhaust¬ 
ing period of flowering. It is gratifying that there is at least one 
besides myself who thinks over-development might have mischievous 
results,. 
I well remember being led to follow a cool system of treatment 
for Odontoglossums, merely keeping frost from the plants during 
the winter. One season was ample to show that the treatment 
was wrong. The plants decreased in health and vigour to such an 
extent that two years’ work became necessary to get the plants in 
the same condition as they were before we altered our method of 
treatment. I learned something, however, by the cool system that 
cannot be too strongly condemned. O. triumphans will bear with 
impunity a lower temperature than O. crispum, and the same may 
be said of 0. Ptscatorei, but even this kind does not recover so 
quickly from a low temperature as the first mentioned. To Ada 
aurantiaca, Odontoglossum cirrhosum, and Mesospinidium sangui- 
neum a low temperature means death ; they are the first to fail. 
To them may be added Masdevallia tovarensis. 
The eradication of white scale from Cattleyas, Lilias, and 
other plants of a similar nature seems to be almost an impossibility. 
No sooner are plants cleaned by the ordinary methods than they

require doing again. The pests seem to establish themselves on 
what I may term the subterranean portions of the plant, and 
increase at such a rate that they can again soon establish them¬ 
selves all over the plant. So far we have found no means more 
effectual than constant watchfulness and going over the plants with 
the sponge and brush at short intervals. Weak solutions of 
carbolic soap are certainly preferable to softsoap for this purpose. 
We have succeeded in cleaning plants by never relaxing our efforts 
until not a trace could be found. Where labour is scarce and 
sponging can only be done to keep the plants presentable 
cultivators may rely upon the labour recurring as certainly as the 
seasons come round. If someone could point out a method by
