KytaU Qsdu&s. 
Since it was discovered that Orchids 
could be raised in this country by the 
crossing of two species a large number of 
specialists have given attention to the 
crossing and recrossing of many species 
until at the present day there must be 
hundreds of hybrids throughout the coun¬ 
try. It is necessary that these should 
be recorded, together with their parentage, 
otherwise the names would be in endless 
and intricate confusion owing to the re¬ 
naming of hybrids that previously existed 
and had names. To obviate this difficulty 
Messrs. F. Sander and Sons, St. Albans, 
published a list of hybrids in their ‘‘‘Cul- “ 
tural Guide,” published in 1901, followed 
by a supplement bringing the list from 
1901 to 1903. In March, 1906, they pub¬ 
lished an entirely new list devoted to all 
the hybrids known-to exist up to date. 
These included the hybrids raised arti¬ 
ficially. together with introduced forms 
supposed to be hybrids and some of which 
have since proved to be. 
In this last vear’s list the hybrids are 
arranged alphabetically under their 
generic names. Then in' Table I. the 
first column is reserved for the name of 
the hybrid, the second column gives the 
name of the seed parent, and the third 
column gives the name of the pollen par¬ 
ent. That is useful so far as it goes, be¬ 
cause if the cultivator knows the names 
of the hybrids he has in his -collection he 
can turn to this list and find the names of 
the parents. Table II. is arranged on a 
different plan ; the first column contains 
the name of the seed parent, the second 
the name of the pollen parent, and the 
third the name of the product. Now in 
this case if the cultivator remembers the 
name of the seed parent he can also find 
the name of the pollen parent and the 
proper name to be given the hybrid. 
Table III., the first column contains the 
names of the pollen parent of a scries 
of hybrids and the second column the 
name of the seed bearer, while the third 
column gives the name of the product, 
that is, the hybrid. Now, whichever of 
these names the cultivator knows or re¬ 
members, he can turn to this list and find 
all the other items which he desires to 
know concerning it. As an example of 
what has been done, it may be mentioned 
that Cypripedium insigne variety Chan- 
tini has many times been crossed with 
spicerianum by different growers, and a 
large number of distinct seedlings have 
been given different names, but they all 
come under C. leeanum, as varieties of it. 
Messrs. Sander have again brought 
their list up to date, namely, from 1905 to 
1907. This, of course, is merely addenda 
to the list, and they are in the form of 
loose sheets, so that they can be inserted 
in their proper places according as they 
represent Table I., Table II., or Table 
III. It is worked out on precisely the 
same plan as the list of “Orchid Hybrids ” 
published last year. 
The Showy Coneflower 
-j 
(Rudbeckia .Speciosa). 
A number of the North American Rud- 
beckias are useful and showy border 
plants, but none more so than R. speciosa. 
Its dwarf habit makes it suitable for small 
gardens and narrow borders. The growth 
is also so regular and even that it may 
with advantage be used for making a bed 
on the lawn, or for planting a bed or large 
clump in the pleasure grounds where less 
time is usually expended by gardeners 
than in the flower garden proper. It is 
a first-class amateur's plant, and is the 
best of the dwarf ones, because hardiest 
and most easy to grow successfully. 
It grows about 18 in. to 2 ft. high, ac¬ 
cording to the fertility of the soil. One 
point to be remembered is that it should 
never be planted in a dry situation, be¬ 
cause the drought of July and August is 
very severe upon it just at the time when 
the plant should be at its best, both grow¬ 
ing and flowering. It requires a con¬ 
siderable amount of moisture, and in a 
dry soil the leaves flag, making the whole 
plant look unhappy. This is more likely 
to happen in a dry gravelly soil than in 
one of a more substantial character. The 
skilled cultivator, however, will soon find 
Rudbeckia speciosa.
