Surfaces of
leaf-forms may or may not have clothing. We now speak of pubescence, a
most important character.
Glabrous refers to a surface with no hairs.
Sub-glabrous refers to a surface with few
hairs. Glaucous refers to a dull
surface that is dusty and powdery.
Glandular refers to the glands on the
surface which may be either sessile or stalked.
Gland-ciliate refers to a surface or an
edge on which the glands are stalked on hairs.
The margins of leaf-forms are often quite lovely,
especially if seen under a magnifying glass. Leaf edges may be singly or doubly
cut, and an edge may be wholly or partly entire, having no cuts, as in
many stipules and bracts.
Crenate refers to an edge on which the snips are rounded in
form. Toothed or dentate refers to an
edge cut like a saw at right angle to the edge.
Denticulate refers to an edge when such
teeth are small and fine. Serrate
refers to an edge when the saw-like teeth are pointed forward.
Ciliate refers to leaf-forms with fine
hairs on the edges like miniature eyelashes.
Gland-cilate refers to leaf-forms with
glands on the edges. Laciniate refers
to a stipule or bract in which the edge is cut into long, narrow, irregular
segments. Fimbriate refers to a
fringed edge. Pectinate refers to an
edge in which the long, incised, firm teeth are like a comb.
The points or tips of stipules, the
auricles or ears, are usually divergent. They often have leafy ends or
slim points, or are ovate, spatulate (in shape of a spoon or paddle) or
they may make a triangle when they are said to be deltoid.
Inflorescence is the habit a rose has
of producing its bloom. Roses may be solitary or in two's or three's, or
even more. Umbel
refers to a form in which all flowers break from one place, as with R.
Banksiae. Panicle refers to a
form in which the flowers break from a central axis with branching clusters
arranged along it, as with the Multiflora and Wichuraiana types.
Corymb refers to a form in which the
blooms are born on peduncles, branching away from the central axis, the stems
growing shorter toward the top, so blooms come out at about the same level.
This is the clustering form most frequently seen. |
Encasing the petals
of a rose are the sepals, five in number, based upon the calyx-tube, the
future seed hip. Sepals are exceedingly interesting.
They may be plain with no
decoration on sides or tips, ending in a cuspidate or a long slim point; or may
be ovate, spatulate or leaf-pointed. Often the sides of the sepals are
decorated with little segments, when they are pinnatifid, having
pinnules. Again, sepals may have these pinnules an points much compounded,
expanded and winged with prettiness, when they are termed foliaceous.
These ramifications may be smothered with glands, as are the Moss roses,
wherein lies the beauty and charm of a Moss rose-bud. Sepals may remain close
to the back of the petals of an open flower, as in Centifolia roses, or may
reflex against the calyx-tube, away from the petals, as in Damascena and the
Chinese roses then reflexing.
The shape of the calyx-tube enters into
the problem of identification. All of the following forms appear in garden
roses. While there may be distortions in shapes, they will be found generally
to approximate the accredited shape. They may be:
Globose (round), sub-globose.
Depressed-globose (wider than deep, as in
Tea roses at times). Ovoid, obovoid.
Pyriform when pear-shaped.
Turbinate when top or turnip-shaped.
Urceolate when urn-shaped.
In many books in which roses are described very
definitely, mention is made of the hip or fruit. Miss Willmott
elaborates in showing and describing fruits, emphasizing such features as
shape, skin, color, clothing, and noting whether they drop the dried
sepals (sepals caducous or deciduous), or do not (sepals
persistent). Skins may be thick or thin; smooth, setose, hispid,
prickly, glandular. The hip may be pulpy like that of the Rugosa or Damascena
roses, or it may be dry and hard, as most are. As the green color goes out,
hips may become orange, red, maroon, and some become black---brown-black as in
Harison's Yellow--or blue-black. At last we
have come to the consideration of the lovely rose itself. While we always look
with pleasure at the petals of a rose, frequently they are of the least
importance in deciding where we are to classify our plant.
We make notes as to whether our bloom
is small (1 to 2 inches in diameter), medium (2 to 3 inches),
large, (3 to 4 inches), very large (4 to 5 inches), or very
small (less than an inch); of its color and shadings, if any; whether it is
single (5 petals), semi-double (5 to 10 rows of petals), double
(10 to 20 rows), very double (more than 20 rows, but still showing some
stamens), full (petals closely packed, stamens imbedded in petals and
not showing). |
