In the centre of the under surface of the corm of last season, in a depression surrounded by the white root-fibres, there are some almost decayed remains of a deep brown hue.
Young corm produced from k', in autumn, which in succeeding autumn will produce flowers.
Old corm shrivelling; b, young corm produced laterally from the old one.
Colchicum illustrates the corm-development which is rare in Liliaceae though common in the allied order Iridaceae; a corm is formed by swelling at the base of the axis (figs.
Corm of Colchicum autumnale in autumn when the plant is in flower.
Charles, as anxious to attack Constantinople as he was reluctant to attack Tunis, with which Sicily had long had commercial relations, was forced to abandon his own plans and to join in those of his brother.
He returned home at the end of 1272, the last of the western crusaders; and thus all the attempts of St Louis and Charles of Anjou, of James of Aragon and Edward of England left Bibars still in possession of all his conquests.
The two distal endites are regarded as corresponding to the endopodite and exopodite of the higher Crustacea, the axis or corm of the Phyllopod limb representing the protopodite.
In a Phyllopod such as Apus the limbs of the trunk consist of a flattened, unsegmented or obscurely segmented axis or corm having a series of lobes or processes known as endites and exites on its inner and outer margins respectively.
At the beginning of the new season of growth, new flower- and leaf-bearing shoots are developed from the corm at the expense of the food-stuff stored within it.
For medical purposes the cormshould be collected in the early summer and, after the outer coat has been removed, should be sliced and dried at a temperature of 130 deg.
In some cases a single corm produces several new plants during its second spring by giving rise to immature corms.
The corm of the meadow-saffron attains its full size in June or early in July.
The parent corm remains attached to the new one, and keeps its form and size till April in the third year of its existence, after which it decays.
This latter is the preparation still most generally used, though the presence of veratrine both in the cormand the seeds renders the use of colchicine itself theoretically preferable.
A smaller corm is then formed from the old one, close to its root; and this in September and October produces the crocus-like flowers.
The juice of the fresh corm in lard has been used by the white man as a local application to cure ringworm.
It is difficult to dig them out still attached to the plant, because the connection between the roots and the corm is so fragile and small.
The disease attacks the corm, and corrodes and decomposes the tissues, so that on cutting open a corm the whole interior, or such parts as are diseased, will be found permeated with a deep, foxy colour.
Immersed in the softer and damper portions of the red substance of the corm may frequently be found great numbers of large compound spores, as illustrated at A (enlarged two hundred and fifty diameters).
The corm should be so placed in the pot as to bring the crown about level with the rim, and every care must be taken to avoid injuring the young roots.
The operation should be so performed as to leave the crown of the corm four inches below the surface.
As the seedlings become ready transfer to small pots, and shift on as growth demands, always keeping the crown of the corm free from soil.
Whichever method is adopted, the crown of the corm should be left about four inches beneath the surface.
In the later stages mix less sand with the soil, and when potting always leave the crown of the corm clear.
Collection, Prices and Uses--The partially dried corm is used in medicine.
The lower part of the corm is flat and wrinkled, while the upper part is surrounded by coarse, wavy rootlets.
Each corm lasts 2 or 3 years before it shrivels, so that 3 or 4 are found horizontally connected.
The varieties are perpetuated and multiplied by the little corms that appear about the base of the large new corm which is formed each year.
They tend to rise out of the ground, because the new bulb or corm forms on the top of the old one.
Root: A corm usually attached to one of the preceding season.
The large buds on the top of the corm correspond to the large buds at the end of your horse-chestnut stem.
The food supply of the bulb is contained in the thick, fleshy scale-leaves, while in the corm it is in the stem," said Frank.
We have seen that the protective bud-scales in the corm are tough and thin, while the stem is swollen and hard.
The corm is covered with brown, papery skins, and has white buds on the top of it," said Frank.
These thin brown leaves of the crocus corm are scale-leaves formed underground.
I am now going to show you that both the cormand the bulb contain a large food supply.
But the greatest difference is in the corm and bulb.
This new cormhas grown upon the top of the old one.
Such a corm is like a tuber in budding from the sides, i.
Corm of Cyclamen, much reduced in size: roots from lower face, leaf-stalks and flower-stalks from the upper.
Corm of a Crocus, the investing sheaths or dead leaf-bases stripped off.
The corm of Cyclamen goes on to enlarge and to produce a succession of flowers and leaves year after year.
It is partly consumed by the growth of the stem for the season, and the corm of the year is forming at base of the stem above the line of roots.
The exhausted corm of the previous year is underneath; forming ones for next year on the summit and sides.
The Corm or Solid Bulb=, like that of Cyclamen (Fig.
It resembles a true bulb in having these sheaths or broad scales; but in the corm or solid bulb, this solid part or stem makes up the principal bulk.
One ramus (the endopodite) alone developed--the original axis or corm serving as its basal joint with or without gnathobase.
The corm becomes the seat of a development of a special visual organ, the Arthropod eye (as opposed to the Chaetopod eye).
In all cases the appendages primarily develop rami or branches which form the limbs, the primitive axis or cormbeing reduced and of insignificant size.
It may be pointed out that the most radical difference presented in this list is that between appendages consisting of the corm alone without rami (Onychophora) and those with more or less developed rami (the rest of the Arthropoda).
The rest of the somites carry equi-formal simple appendages, consisting of a corm or axis tipped with two chitinous claws and devoid of rami.
Fresh roots are formed, some of which, having penetrated the soil to a varying depth, contract in length, and so draw down the new corm to the level of the old.
The reason for setting the stakes early in the season is--you know just where the corm is then, but later on you will not be able to tell where the new corms are, and in setting the stakes at random you are quite likely to injure them.
It is often difficult to decide this matter before sprouting begins, but a little careful examination of thecorm will soon enable you to tell where the sprouts will start from, and this will prevent you from getting it wrong-side up.
Note, however, that the new corm is not on the same level as the old one.
When a corm commences to grow, the reserve material within it is used up for the benefit of the flowers and leaves.
This latter has practically vanished up the main axis from the disc to produce flowers and leaves--hence it follows that the Tulip bulb somewhat resembles the corm in its vegetative characters.
The new corm instead of being produced on top of the old one, is developed at the side.
The vegetation of the corm is very remarkable, and somewhat resembles that of the Tulip.
At the base are seen the withered remains of the corm which was planted in the spring, and above it the new corm which will furnish bloom the following season.
Each bud on the top or side of the corm may be made to produce a separate corm by cutting a deep ring around it, so as to partly divide it.
Or the corm may be directly cut into as many separate pieces as there are buds or eyes, after the manner of cutting potatoes, but these pieces are usually handled in flats where temperature and moisture can be controlled.
As a rule, a new corm is produced each year above the old one, and this commonly bears flowers the following season.
These are removed from the parent corm and planted in the open, where some of them will flower the same season, although most of them will require a season's independent growth before they flower.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "corm" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: bulb; radix; root; seed; tap; taproot; tubercle
