THE DICTIONARY OF GARDENING, 
SEQUOIA. Wellingtonias, in common with some other 
coniferous subjects, are attacked by a fungoid disease, a 
Botrytis-form of Sclerotinia Fuckeliana. The greyish mould 
is very familiar, as it is fonnd upon a variety of subjects. 
Young trees are the yictims, the fungns atfacking the 
main shoots. All diseased trees should be taken up 
and burned, and the remainder thoroughly sprayed with 
weak Bordeanx Mixture. 
To the species and varieties described on p. 422, Vol. IIL., 
the following should be added : 
S. gigantea pyramidata compacta (pyramidal, compact). 
A garden form, of compact, pyramidal growth. 1891. 
S. sempervirens variegata (variegated). A form differing 
from the type in having highly glaucous and slightly variegated 
foliage. 1890. 
SERAPHYTA. S. multiflora is the correct name 
of S. diffusa. 
SERIOLA. Included under Hypocheris (which 
see). 
SERRASTYLIS (from serra, a saw, and stylis, a 
style; in allusion to the toothed wings of the column). 
Orv. Orchideex. A monotypic genus. The species is a 
stove Orchid allied to Brassia and with the habit of 
Trichopilia. It will probably thrive under the treatment 
recommended for Oncidium. 
S. modesta (modest). #. lin. in diameter, numerous, in a 
drooping raceme Sin. long; sepals and petals reddish, edged 
with yellow; lip white, with a few purple streaks; column 
having two large, wing-like auricles, the side lobes of the lip 
similarly formed. J. solitary, broadly lanceolate. _Pseudo- 
bulbs linear-oblong. Colombia, 1893. (G. C. 1894, xvi., 
p. 726, f. 91.) 
SERRATULA. Other species formerly included 
hereunder are now referred to Jurinea, Pluchea, and 
Saussurea. 
SERRATURE. One of the teeth of a serrated 
margin. 
SESBANIA. To the species described on p. 425, 
Vol. IIL., the following should be added: 
S. exasperata (roughening). 7. golden-yellow, with red spots 
on the back of the standard, large, papilionaceous, disposed 
in short racemes. J. 6in. to 10in. long. Branches_ slender, 
h. 8ft. to 10ft. Tropical America, before 1894. (B. M. 7384.) 
S. platycarpa is the correct name of S. vesicaria. 
S. Tripetii (Tripet’s). #. in drooping racemes; standard 
searlet, much paler on the inner face, with a yellow spot on 
the claw; wings and keel palish red. June to October. 
7. dull green above, glaucescent beneath. h. 6ft. Brazil and 
Argentina. Greenhouse. Syn. Daubentonia Tripetit. 
SESIA TIPULIFORMIS. ‘See Currant Clear- 
wing Moth or Currant Borer. 
SETACEOUS. Bristle-like. 
SETARIA ITALICA. The 
Panicum italicum (which see). 
SETS. In some parts of the country the tubers of 
Potatoes, Dahlias, and similar things are termed ‘‘Sets.”’ 
These may be whole or parts of Potatoes. In some 
parts cut Sets are preferred, and in others whole Sets. 
SETTING. The fertilisation of the female blossom 
with the pollen from the male blossom is known as 
Setting. When certain varieties of Melons, Tomatoes, 
and Grapes are naturally more or less shy in producing 
fruit, although producing plenty of female flowers, they 
are known as shy Setters. 
SEWERZOWIA should be included under Astragalus, 
and the correct name of S. turkestanica is A. Schmalhausent. 
SHANKING. The canse of Shanking—i.e., the 
drying up of the stems of the berry of the Grape, the 
stems of yonng plants of the Brassica family and many 
other plants—is somewhat difficult to determine, as so 
many things contribute to the condition. With Grapes, 
the following are amongst the principal contributory 
causes: careless or bad ventilation of the Vineries, such 
as sudden dranghts of cold air after the house had become 
very heated; too much or too little water at the roots; 
extremes in the atmospheric moisture of the house; bad 
drainage; exhaustion of the soil or of some element 
therein, particularly lime ; oyer-rich soil, or the application 
of too much natural or chemical manures, and the 
correct name of 
Shanking—continued. 
passing of the roots out of the prepared border into 
some unsuitable material or soil. 
Shanking will appear in the berries at yarions stages, 
sometimes when they are qnite small and no larger than 
Peas, often at the stoning period, and also when the 
frnit is commencing to colour. When the latter ocenrs 
it is usually produced by over-cropping the Vines. When 
the stems of young Cauliflower, Lettuce, &c., Shank in 
frames early in the season, it is largely dne to over- 
crowding or insufficient ventilation. In the open ground, 
frost, a lack of lime or potash, and overcrowding will 
cise the stems to Shank. Or the collapse of stems may 
be due to a fungus. See Damping Off. 
Fic. 675. SHIRLEY POPPlIEs. 
SHARP CEDAR. Se 
Acacia oxycedrus and 
Juniperus oxycedrus. 
SHE OAK. See Casuarina stricta. 
SHEEP LAUREL. See Kalmia angustifolia. 
. SHEK-IN. See Primulina Tabacum. 
SHELLS. These are all useful as a manure when 
pounded up, the roots showing their appreciation by 
clinging round the broken pieces, no doubt for the lime 
and other useful constituents contained therein. Oyster- 
shells are excellent for many plants, such as Chrysan- 
themums, for drainage, and supply a certain amount of 
plant-food at the same time. 
SHEPHERDIA. SF. argentea is in gardens often 
confused with Elwagnus argentea, which is a distinct, 
althongh related, plant. 
SHEPHERD'S BEARD. 
SHEPHERD'S CLOCK. 
tensis. 
SHERBOURNIA (named in honour of Mrs. Sherbourn, 
who first flowered the plant in England). Orp. Rubiacezx. 
A monotypic genus. The species is an unarmed, scandent, 
pubernlons or glabrescent, stove, evergreen shrub or tree, 
formerly included under Gardenia (which see for 
cultnre).
