THE GARDENING WORLD. 
June 20, 1903. 
A plantation of species and varieties of Gemii includes some 
of the finer types now in cultivation. One of the dwarfest is 
Geum montanum, with dark green leaves and large bright 
yellow flowers. G. pyrenaicum is of taller habit, but the 
golden-yellow flowers are smaller. The leaves are also less 
divided, with a. large terminal lobe. Geum Orange Queen 
seems to be a hybrid with yellow flowers about the size of 
those of G. montanum, but the stature of the plant is even 
greater than that of G. pyrenaicum. One of the most interest¬ 
ing of recent introductions is G. Heldreichi, with flowers of a. 
rich intense orange, somewhat smaller than, those of G. mon¬ 
tanum. This species comes from Greece, and is evidently 
capable of being greatly improved either by crossing with 
other species or crossing with its own varieties and by select¬ 
ing the seedlings having the largest and best-coloured flowers 
with the' greatest quantity of them. The flowers of G. Ewenii 
are as large as those of G. montanum, but of a light orange. 
A beautiful Heron’s-bill is Erodium pelargonifolium. The 
plant is of dwarf habit, close, bushy, and furnished with deeply 
three-lobed leaves. The flowers are white, with a purple 
blotch on each of the two upper petals, and beautifully 
feathered with purple veins. The whole plant was under 6 in. 
in height. An uncommon Silane is S. virginica, with stems 
about 12 in. long, spreading, and bearing cymes of scarlet 
flowers with obovate petals. The* leaves are more or less tinted 
with bronzy purple. This might be planted on the rookery. 
Its near relative, Lychnis Viscaria. alba-, lias white flowers, 
and is pretty in the mass. A new variety of Ox-eye Daisy is 
Chrysanthemum Leiucan.theaium Daviesi. The flowers are 
much larger than, the common form, and the rays are imbricate. 
The leaves are slightly serrate, and carried up the stem almost 
to the flowers. The stems are branching, making the plant 
suitable for cut-flower purposes. 
Some of the forms' of Poleanonium himalayanum are pretty 
and interesting at this period of the' year. They are dwarf 
in habit, and may be planted on the rockery with as good 
effect as in the' herbaceous border. The flowers of the type are 
large and light blue, with broadly ovate blunt segments. The 
variety P. h. album has pure white flowers, and makes a 
beautiful contrast with the type. P. h. elegans has white 
llowersi beautifully rayed with violet-purple in the centre, and 
having a delicate flush of the same hue extending down the 
segments. Several of the Poppies are interesting at present,, 
but by no' means common are the orange flowers of Papaver 
pilosum and P. rupifragum. Both are perennials, but the 
former is distinguished by its broad hairy leaves and decidedly 
caesious hue. The last-named has linear more or less lobed 
and green leaves. 
St„ Bruno’s Lily, correctly known, as Paradisea Liliastrum, 
but known by various other names, is at present a, very in¬ 
teresting subject with its funnel-shaped white flowers borne 
on racemes about- 1 ft. high. The last-named belongs to the 
Lily family, as do the day Lilies represented by Hemerocallis. 
One of the most common, and at the same time most useful, is 
H. fiava, with clear yellow flowers borne on long stems clear 
above the foliage, and therefore very useful for cut flowers. H. 
Gold Dust is evidently a variety of H. Middendorffi, or H. 
Dumo-rtieri, having yellow flowers overlaid with a deep bronzy 
hue on the outside. Two plantations of Knipho-fia T'uckii look 
like a regiment of soldiers or sentinels bearing large spike® of 
bloom like a, Turk’s Cap. In the hud state the flowers are 
bright red, but become primrose when fully expanded, each 
spike being about half and half in colour at a certain stage of 
growth. 
The named varieties of Pyrethrum have been, in full bloom 
for some time past. One of the best we noted was that named 
Hamlet, having rosy flowers of pleasing hue, showing up well 
under artificial light. In the cut state this class of flowers 
lasts a. long time in a fresh condition, becoming more fully 
developed during the course of a fortnight. 
Irises in great- variety have been quite- the. glory of the 
warden for some weeks, and different- species will continue a 
succession for weeks to come. A pleasing and beautiful white 
form is L. orieatalis White Queen, forming a very striking 
contrast to I. Blue King, having flowers of an intense blue 
with the disc of the falls variegated with blue, white, and 
yellow, while the claw is ornamented on another pattern. Few 
of the Irises are more handsome than t-lie various forms of I. 
pallida, with their massive blooms of delicate shades of lilac, 
purple, and lavender. Several varieties of this glorious Iris 
are grown here. The flowers of I. variegata Newbronner are 
o-olden-yellow tinted with orange, and the falls ornamented 
with darker orange lines. I. lo-ngipetala reminds us of the 
markings of La-elia majalis. The falls are lined throughout with 
soft blue on a white ground, and are yellow on either side of 
the central ridge. I. cretersis- has large handsome white 
flowers, in. form resembling those of the German Irises, but 
white, and lined with yellow on the- claw of all the- segments. 
At- a distance, however, the large flowers ha-ve the appearance 
of being pure white, and we should reckon this- the finest white 
of the large flowering bearded Irises. Compared with the last- 
named, L. cristata is quite a miniature type, varying from 3 in. 
to 5 in. in, height, but often under the latter figure. The falls 
are relatively large, with a white blotch on the disc surrounded 
bv a deep purple line, while the rest of the falls is blue-purple. 
It is quite a- little pet- of an Iris, and should be planted in moist 
positions- at the foot of the rockery. I. Princess of Wales used 
to be the finest, white, but I. cretersis has much larger flowers 
and is equally as pure. 
Many Columbines are in bloom at the- present time, but few 
of them excel the beauty of Aquilegia glandulosa, having large 
bright blue flowers, with the upper half of each petal white, 
and therefore highly conspicuous. The plant is of dwarf habit, 
being 9 in. to 12 in. in height. Closely allied to this is the 
newer form named A. angulosa, the petals of which are less 
spreading and very erect, partly closing up the centre of the 
flowers by comparison with those of it-s congener. 
The new Cheiranthus Allioni looks very much like a hybrid 
between C. alpinus and Erysimum perofskianum. Evidently 
it is- not a- long-lived plant, but produces orange flowers in 
great- abundance' and develops seed, which is not- the case w it-h 
the- better-known C. Marshallii. The new Aubriet-ia Moerheimi 
has gray foliage and large soft, pink flowers. The double 
flowers' of the Welsh Poppy are- in very tine condition, having 
large and globular orange and perfectly double blooms. In 
fine condition was a large batch of Ranunculus aco-nitifolius fl. 
pi., having an abundance of double pure white flowers. A cry 
fine also was Primula ja-ponica- alba, having a red eye t-o its 
white flowers. 
The double perennial Candytuft Iberis se-mpervirens plena- 
is not a particularly common plant, and is quite distinct in its 
W ay, the flowers remaining in good condition until the racemes 
have become elongated. The Edelweiss (Leontopodium al- 
pinum), grown in, quantity, was- in full bloom. Amongst the 
species of Thyme we noted a- quantity of Thymus cit-riodorus 
Fraser’s Silver, having broad silvery margins- to the leaves, and 
constituting thus the best variegated -.form of the Lemon 
Thyme. A very interesting plant- for the rockery is Hippo- 
crepis coinosa, with lit-t-le golden coronets of bright yellow 
flowers. It- is. a native of our chalk downs, and a, neat and 
handsome plant. . 
Several species of Polygonatum are grown m a. certain part 
of the nursery and amongst them wo noted a dwarf species 
of Solomon’s Seal—namely, Polygonatum Thunbergii, under 
the name of Co-nvallaria Thunbergii. The species is notable 
for its dwarf habit, even, height, and beautiful light gieen 
foliage. Though the stems are 12 in. to 18 in. long, their 
arching habit makes the plant much dwarfer. The flowers are 
cylindrical, white, with green tips, and produced m clusters 
of two to four. 
Opposite and Alternate Leaves. —At the meeting of the 
Linnean Society, on the 4th inst., Mr. Percy Groom read a 
paper on the transition of opposite leaves into the atterna 
arrangement. This he also entitled a new factor m morpho¬ 
logic observation.
