The orchid family is such a diverse and interesting group of plants that it should not be a surprise when a few new vocabulary words are necessary to fully understand their growth and care.
Sympodial orchids have a horizontal stem called a rhizome that grows outward and spreads along the surface of the growing medium.
Flower spikes on sympodial orchids originate between the leaves at the top or from the base of a new pseudobulb.

 botany/orchidaceae
Sympodial orchids, such as Cattleyas, form a horizontal stem called a rhizome that produces new shoots from buds.
Sympodial Orchids (those that grow horizontally) should have enough space between the youngest shoot and the rim of the pot to allow for two years of growth.
Sympodial Orchids (those that grow horizontally) can be divided by cutting the rhizome so that each division has three or more growths and one actively growing lead.

 Mycology Online -- Fonsecaea
Initial sympodial development of primary conidia is similar to that seen in Rhinocladiella (raduliform), except that the conidiogenous zone is confined to the upper portion of the conidiophore.
Raduliform sympodial development is where the elongating conidiogenous axis is relatively wide compared to the width of the conidial attachment and the axis tends to become clavate or somewhat inflated rather than zig-zag.
Since the sympodial development of both primary and secondary conidia is both distinctive and stable, this mode of development should be used as the basis for defining the genus Fonsecaea.

 Comprehensive Culture Guide—Potting orchids part A
Sympodial orchids, such as Cattleyas, Oncidiums, Cymbidiums, Paphiopedilums, have several, sometimes dozens of successive growths.
In sympodial orchids the life of each growth is determinate (meaning it will last 3, 4 or 7 seven years) but the life of the plants may be, in theory, unlimited.
The Manual of Cultivated Orchid Species (by Helmut Bechtel, Phillip Cribb and Edmund Launert, MIT Press) says : “the longevity of orchid plants in cultivation is still something of a mystery, for several plants in the orchid greenhouses at Kew are over 100 years old and are still thriving and flowering regularly”.

 Sympodial Cyme   (Site not responding. Last check: 2007-11-07)
A special type of modified cyme which superficially resembles a raceme or spike is the sympodial cyme, in which the apparent main axis consists of a succession of short axillary branches.
Sympodial cymes are of two types, helicoid and scorpioid.
In a scorpioid cyme the branches are alternately on opposite sides of the developing sympodial axis, so that the axis has a zig-zag appearance.

 Repotting Plants
Sympodial plants - cattleyas, dendrobiums, etc. - grow on a rhizome, with each plant maturing and blooming individually.
If the older growths of sympodial plants - those on the opposite end of the "chain" from where it is blooming - are old and very shriveled, it is safe to cut the rhizome and throw them away.
The older pseudobulbs do serve as "storage tanks" for the rest of the plant, and still provide some photosynthesis, and this is true even if they have lost their leaves.

Though both monopodial (having single stemmed growth) and sympodial (having multi stemmed growth) are equally used in commercial cultivation, sympodial types (Cymbidium, Dendrobium etc) rank higher in the export market.
The sympodial genera suitable for Kerala, are Cymbidium (at high altitudes), Oncidium and Cattleya, and the monopodial genera are Vanda, Arachnis and Phalaenopsis.
However, better attention in planting, regulation of shade, irrigation, nutrition, plant protection and post harvest handling is necessary to produce quality flowers.Planting In sympodial orchids, the propagule is placed near the edge of the container the growing point facing the centre.

Orchids are capable of crossing the boundaries of both species and genus when it comes to breeding and as a result there are thousands of intergeneric hybrids that we humans have created in addition to the native species that inhabit the globe.
Many sympodial orchids have a water storage organ called a pseudobulb to which a single or double leaf is attached at the top.
The genus Cattleya is made up of sympodial orchids and these are the flowers most people think of when they hear the word “orchid”, picturing large colorful corsage orchids.

 Comprehensive Culture Guide—Potting orchids Part B
But for many sympodial orchids, such as Cattleyas, Dendrobiums, Oncidiums,...the new growth(s) develop along a rhizome and usually tend to grow in the opposite direction of the old growth(s).
The procedure for potting these is the same as for Phalaenopsis except that instead of centering the plant you want the older portion of the plant as close to one edge of the pot as you can get it, leaving room on the opposite side of the pot for the new growth(s).
On some sympodial orchids such as Cymbidiums, Jumeleas, Paphiopedilum, Phragmipedium,...the new growth(s) will be very close to the base of the old growth(s), forming sort of a circle around the older growth(s).

 Fruiting Distribution Patterns Among Three Cotton Varieties Under Irrigated Conditions
Kerby and Buxton (1981) reported that 76% of the bolls retained were on the first position of sympodial branches, and that six to eight percent of the bolls retained came from fruiting sites other than positions one and two on sympodial branches.
Although, when sympodial branches were pooled together into zones consisting of six nodes per zone, there were significant differences among cultivars with respect to vertical fruiting patterns (Figure 3).
Zone 1, consisting of sympodial branches one through six, showed a significant difference between DP 33b and Pima S-7 (observed significance level, OSL=0.0439) with Pima S-7 producing a significantly higher yield at Zone 1.

 Constancea 83.10: Tapeinodasya, a genus of the Dasyaceae
The morphology of the horizontally orientated holoblastic sympodial branches is bilateral with pseudolaterals deflected to two opposite sides of the sympodial main axis (Figs.
Due to the sympodial construction of the thallus, those holoblastic branches are modified and become sympodial monosiphonous or polysiphonous branches, called pseudolaterals.
As the plane of division of the apical cell determines the side to which a branch is formed, the primary branching pattern is defined by the division of the apical cell into a new apical cell and a subapical cell.

They are potted in either an epiphytic or a tropical terrestrial seedling compost as appropriate.
Sympodial orchids (new growth appearing from the base of an older growth) can be propagated through division.
Cut through the rhizome leaving ideally at least three growths on each portion, this can be done at any time, providing the plant remains undisturbed in its original compost until the next re-potting takes place, when you should have perfect divisions.

 Why be sympodial?   (Site not responding. Last check: 2007-11-07)
Sympodial species must be able to support the thick stems which arise below each flower head.
Monopodial species can rapidly grow long, thin stems and then produce side branches lower down where the stem is thicker.
This allows much faster growth which should allow monopodial species to out-compete sympodial species.
