| − | [[Orchid]]s with '''sympodial''' growth have a specialized lateral growth pattern in which the terminal [[bud]] dies. The growth continues by development of new shoots sprouting from or next to the ones of previous years (such as in the genus ''[[Cattleya]]'' or ''[[Cymbidium]]''). | + | [[Image:Upload.png|thumb|[[Special:Upload|Upload image!]]]] |

| − | The base of the [[Plant stem|stem]] of sympodial [[epiphyte]]s, or in some species essentially the entire stem, may be thickened to form what is called a [[pseudobulb]]. These contain food reserves for drier periods. At their end appear one or two [[leaf|leaves]], or sometimes four or more.

| − | Some sympodial [[terrestrial plant |terrestrial]]s, such as ''[[Orchis]]'' and ''[[Ophrys]]'', have two pseudobulbs between the [[root]]s. One is used as a food reserve for wintery periods, and provides for the development of the other pseudobulb, from which visible growth develops.

| − | | |
| − | In warm and humid climates, many terrestrial orchids do not need pseudobulbs.
