'''''Chysis''''' is a [[genus]] of [[orchid]]s ([[family (biology)|family]] Orchidaceae), consisting of about 5 [[species]] which originate from [[Mexico]] to [[Peru]]. Only two or three of these are commonly found in cultivation.

==Description==

==References==
−
The genus is typified by elongate, [[spindle]]-shaped, usually pendulous [[pseudobulb]]s of several [[internodes]], which may be fat or slender, depending on the species. The [[leaf|leaves]] tend to be quite soft and papery, strongly ribbed and long. The leaves can take a good deal more light than is apparent from their thickness. This genus also tends to be partially [[deciduous]], though leaves are often retained for two years.

The [[inflorescence]]s are multi-[[flower]]ed and arise from the base of the pseudobulb with the new growth. Flower colour tends to range from white (as in ''[[Chysis bractescens]]'') to orange-yellow (as in ''[[Chysis aurea]]'' and ''[[Chysis laevis]]''), and the [[pollinia]] often tend to be fused (hence the genus name '''Chysis''' which is [[Greek language|Greek]] for "melting").

''Chysis'' are [[epiphyte|epiphytic]] and grow under shady and damp conditions up to 1000 meters elevation. The plants should be grown under intermediate conditions, generally mounted due to their pendulous habit, though some species adapt well to pot culture. The plants are greedy should be watered and fed heavily while they are in active growth, though rather less once the seasons growth is completed. They should never be allowed to completely dry out, however, even during the rest period, and the pseudobulbs should never be seen to shrivel.
