THE QARDENI1S/Q WORLD 
April 11, 1903. 
The records of the yield, and the date of first bloom of 
Tomat-os grown from seed and also from cuttings, show no 
increase in weight of the fruit grown in the light,. though the 
blossoming period was from eight to eighteen days earlier, and 
the individual fruits were generally larger than when grown 
under normal conditions. 
In. these experiments no injurious effects resulted from the 
use of incandescent gaslight. This is important to know, as 
many conservatories are at the present time being fitted up 
with this artificial system of lighting. 
Tulipa kaufmanniana. 
The days of tulipomania are past, yet sufficient interest 
animates the lover of Tulips to desire a longer flow r ering season 
for those floral beauties. For this, reason attention is drawn 
to the above early-flowering species, which opens its flowers the 
second week in March. Discovered by Dr. A. Regel in Turkes¬ 
tan, it is closely allied to T. gesneriana, and resembling it in 
its variableness in colour, which ranges through shades of light, 
yellow to white. In many of the forms the reverse of the outer 
whorl of segments is entirely red, with a white margin, flushed, 
or with a band of red up the middle. The usually two oblong 
glaucous leaves are about 6 in. long, and frequently l-% in. to- 
3 in. wide ; of a similar length is the peduncle, supporting a 
sub-campanulate flower, 2^ in. long, with widely-spreading seg¬ 
ments when expanded, revealing the conspicuous oblong yellow 
blotch at the base of the segments. Reflecting on the numerous 
handsome garden varieties derived from T. gesneriana, we pre¬ 
sume that were this form subjected to the same process of 
selection and intercrossing, a strain of early-flowering Tulips 
might be obtained equalling the above-mentioned varieties. 
Iris warleyensis. 
A pretty, early-flowering plant, well adapted for culture in a 
cold frame. The distichously-produced leaves, fully 6 in. long, 
are linear-lanceolate and recurving, with sheathing bases; the 
upper surface is polished, green, with a white margin; lower 
surface paler. Slightly longer than the leaves is the flower- 
spike, producing four to six flowers each in the axil of an erect 
leaf-like bract. The pleasing flowers have nearly obsolete 
standards, falls without lateral flanges, nearly spatula,te, having 
the flat petiole-like portion ascending, and the round apical 
one-third sharply deflexed. The lower two-thirds are pale 
lilac, with parallel black-and-white line-like markings, whilst 
the apical portion has a yellow centre with broad blue- zone, 
lilac margin, yellow and white tipped ridge. 
The erect, slightly-twisted stigmas have slightly-serrated 
deeply-cut lobes, of a lilac colour, with a metallic lustre. In 
the arrangement and colour of its leaves it closely resembles 
those of I. tubergeniana., differing in the colour of its flowers 
and inflorescence. 
Notes on the Illustrations in this Issue. 
Ostrowskia magnifica. 
The above noble Bellflower lias never become very popular 
since its introduction in 1887, notwithstanding its singularly 
distinct character. The only other Bellflmver in the order to 
which we can compare it is Michauxia campanuloides, and to 
the latter only in respect to its widely-expanded flowers. In 
other particulars it- is veiy different from that North American 
plant. The subject under notice comes from Central Asia, and 
lias found its way into a few gardens ; but should cultivators 
hit upon the right method of cultivating it, we should expect 
to see it widely cultivated in a few years. 
The stems vary in height from 2 ft. to- 5 ft., according to 
the >age of the plant and the vigour with which they have 
grown, but w r e fancy it has rarely happened that cultivators 
have succeeded in getting the last-named stature. It was our 
pleasure to see a plant of that height in the garden of J. Brad¬ 
shaw, Esq., .The Grange, Southgate, some years ago. The 
illustration representing this Bellflower is evidently taken from 
the identical plant which we noted on the occasion to which 
we refer, and was possibly photographed the same year by Mr. 
George I’Anson, who sent the photograph for our recent photo¬ 
graphic competition. Only the top of the plant is here repre¬ 
sented, but it certainly was a stately specimen, and lilac in 
colour. 
The plant in question was grown in an ordinaiy shrubbery 
border, thinly planted, so that flowers could be grown between 
and in front- of the shrubs. Mr. Bradshaw is an enthusiastic 
hardy plantsman as well as a collector and grower of choice 
Orchids. This, then, we may regard as one of his specialities, 
or at least one of his signal successes. The plant was in front 
of a low brick w r all, facing the north, if we remember rightly, 
and by this means the ground w T as shaded during the hotter 
part of the day, and therefore kept- cool. The conditions 
would seem to be veiy much the same as those that ensure 
the success of many of the Lilies ; and we think that if other 
cultivators would adopt- some similar plan, or even plant it in 
beds of Rhododendrons sufficiently far apart to furnish spaces 
for Lilies and plants of that character, it would succeed. The 
least interesting feature of the plant, in o-ur opinion, is the 
pale colour of the flowers, but we think if cultivators could 
succeed in growing the plant some of them at least- would 
attempt the raising of seedlings with the view of getting 
varieties, with a- better colour. There can be little doubt that 
if once the plant could be got to vary slightly from the normal, 
it could be greatly increased by the crossing of the better 
varieties together. This in itself would encourage variation, 
and no doubt improvements as well. 
Cypripedium Venus Oakwood var. 
The parentage of this beautiful hybrid was C. albanense x 
boissierianum ; it would therefore belong to- the genus Seleni- 
pedium, according to those who take that view of the matter. 
The parentage is- also- somewhat complicated, seeing that C. 
albanense is itself a hybrid from C. Schlimii x Sedeni, and that 
again was a hybrid. Thei result- is a Cypripedium that has 
been greatly improved both in form .and colour. The white 
colour of C. Schlimii has had the effect- of removing the green 
and other pale colours seen in C. boissierianum. It is needless 
to- describe the form of the flower, seeing that it- is so well 
represented in the illustration to which this note refers. The 
flowers, however, are of large size, of a soft creamy colour, 
shaded with pink, and slightly tinted with green. As will be 
seen, there are numerous small specks on the dorsal sepal and 
the petals. The photograph was taken by Mr. H. J. Chapman, 
who is well known amongst Orchid growers, and it was sent 
for our photographic competition by him. 
Dendrobium luteolum. 
The genus Dendrobium is a large one, and, notwithstanding 
the similarity in the form of the flowers, there is a great range 
of variation, and something to please the taste of everyone. 
That under notice blooms in winter at a time when flowers 
are relatively scarce, which in itself would be a- plea for its 
more extended cultivation. 
It has a slender, upright growth, and the flowers are produced 
in short ra-cemes from the nodes near the top of the stem. 
The illustration representing this species will give a good 
general idea- of the appearance of the plant when in bloom. 
The flowers are somewhat smaller than those of D. nobile, and 
soft primrose-yellow, so that a good plant of it would be- both 
distinct and ornamental amongst the other types which flowei 
at that- period of the year. The photograph was taken by Mi. 
Charles Jones, The Gardens, Ote Hall, Burgess Hill, Sussex, 
who cultivates a great- variety of plants.
