		A bud on the stem of the axil.
		An old, sometimes leafless, sympodial pseudobulb that is still alive and may be used to propagate a new plant.
		The method of seed propagation of an orchid wherein the pollen of one orchid is placed on the stigma of another orchid which was originally grown in the same seedpod as the first orchid, therefore a cross-pollination of siblings.

	Orchids Growing & Orchid Background Information
		Pseudobulbs have a smooth surface with lengthwise grooves.
		When the orchid has aged and the pseudobulb has shed its leaves, the pseudobulb becomes dormant and is called a backbulb.
		At the end of the pseudobulb typically appear one or two leaves, though there may be up to a dozen or more.

		On each side of a pseudobulb in the axis of the leaves are a series of buds.
		At the end of three years the original single pseudobulb has developed into a three lead plant, the most recently matured pseudobulbs producing a two lead growth and single lead growths., The right had illustration is only for the first 2 years.
		The old defoliated pseudobulb is buried to one third to half its depth in potting mix in a small pot, and over several months most will develop a new growth.

	Abaxianthus
		The pseudobulbs are small, hard and cone-to-egg-shaped, each occurring on a single stem.
		Abaxianthus is derived from the Latin abaxialis, away from the axis and anthus, flower, in reference to the flowers arising from the apex of the pseudobulb behind the leaf, not in the leaf axil.
		Inflorescence single-flowered, arising from a meristem situated at the apex of a pseudobulb on the abaxial side of a leaf; each meristem consists of a small cavity with a sheathing bract and is capable of producing a single flower only.

	Pseudobulb - Wikipedia, the free encyclopedia
		The pseudobulb is a storage organ derived from the part of a stem between two leaf nodes.
		It applies to the orchid family (Orchidaceae), specifically certain groups of epiphytic orchids, and may be single or composed of several internodes with evergreen or deciduous leaves along its length.
		The pseudobulbs are themselves relatively short lived (1-5 years), but are continually produced from the growing tip of the rhizome.

	Notes de culture des orchidées préparées par les orchidophiles de Montréal
		As soon as the pseudobulb is formed, reducing waterings and cutting down the fertilization triggers the blooming.
		Pseudobulbs indicate the need of a resting period in fall or in early winter.
		The pseudobulbs in these plants indicate that a resting period is needed; by the end of the Fall waterings are reduced as well as the temperature.

		The pseudobulb has the same function as the barrel of a cactus; it holds water and nutrients.
		The plant is made up of groups of pseudobulbs connected by a rhizome.
		New growth typically comes off of the youngest pseudobulb as an active eye at its base 'sprouts' at the beginning of the next growth cycle.

		The pseudobulbs of the current year usually mature by the end of June under usual greenhouse conditions in Ithaca, N. The inforescnce develops from the apex of the new pseudobulb.
		This part of the pseudobulb was therefore used in studying bud initiation and bud development.
		The tips of the pseudobulbs were collected and examined at regular intervals of 2 weeks starting May 28, 1949, to determine the normal date of bud initiation.

		When a new growth appears at the base of the pseudobulb, is the time to repot the plant.
		Simply pot the pseudobulb so that the new growth is at the surface of the potting media.
		If several growths appear along the sides of the pseudobulb, then it can be laid on the surface of the potting media.

		Generally one flower of excellent quality develops first from the base of the newest pseudobulb and this is followed by the spring flush.
		From three to five flowers per pseudobulb are usual, especially for hybrids bred from Lycaste skinneri but 30+ flowers over a period are possible from the deciduous species and their hybrids.
		At maturation of the pseudobulbs (when the small sheathing bracts turn brown and fall off) decrease the frequency of watering considerably for those species that retain their leaves.

		These pseudobulbs are so named because, like bulbs, they are storage organs for food and water and can carry plants through short periods of drought.
		The pseudobulbs are usually light green in color, but they vary widely in shape and size.
		A new pseudobulb is produced annually at the end of a new, short length of rhizome.

		The true stem is an underground rhizome commonly called a pseudobulb producing leaves and a fruit stem from a growing point on its upper surface and roots from its lower surface.
		The blossom stem arises from the central growing point on the pseudobulb and pushes upward through the center of the pseudostem, protected by the encircling leaf sheaths.
		Its place is taken by a sucker that has been allowed to develop from the pseudobulb and it eventually produces a bunch of fruit only to give place to still another sucker as the cycle as the cycle of fruit production continues in the plantation.

		As a general rule, the taller the plant, the thicker the pseudobulb.
		The flowers which are produced on the apical portion of the pseudobulb can be single or up to as many as 30 + on an inflorescence.
		Each pseudobulb, depending on the species, can produce one to several spikes with some producing up to 6 or more.

	Orchid Types
		The rhizome lies horizontal to the surface of the ground and sprout roots along its length in a downward direction and produce thickened vertical stems called pseudobulbs.
		Each pseudobulb will generally have one or two leaves at its top.
		New growth begins at the base of the leading pseudoblub from a place called an "eye." Many of these orchids also form a specialized leaf-like structure called a sheath at the base of the leaves of the leading pseudobulb in which the flower is formed.

		Resist picking up the plant to inspect those beautiful buds and then setting it down in all different directions as the flower buds will be forced to re-orient themselves to the light source each time and will not open as nicely as they should.
		If your plant's pseudobulbs are shriveled, then the plants have been kept too dry or too wet.
		If the lead pseudobulb is large, plump and green (and back bulbs are shriveled) but no flower spike is evident, the plants may have been kept too dry.

		The pseudobulb will be plump and the plant full of vigor.
		After flowering your plant will start to lose its leaves from the flowered pseudobulb and this is a sign that your plant is deciding to go into its rest/dormant stage.
		As the pseudobulb matures, thought should be given to the outcome of male or female flowers and which is desired.

	Cattleya maxima
		It is referred to as the “short pseudobulb” or “upland” C. maxima and was the only C. maxima in cultivation until 1864.
		The color of the flowers in the short- pseudobulb type seems to give the plant most of its appeal, while the large size of the plant and flower head in the tall- pseudobulb type is both an asset and a liability, depending on the amount of space a grower has to give the plant.
		Cattleya maxima should be repotted as soon as it makes new roots from the lead pseudobulb, and should be fertilized only when it is actively growing in the spring and summer.
