Ascocenda: × Ascocenda, abbreviated as Ascda in the horticultural trade, is a man-made hybrid orchid genus resulting from a cross between "Ascocentrum" and "Vanda" (Asctm × V).  It was first described in Orchid Rev. 57: 172 (1949).

Paphiopedilum barbigerum: Paphiopedilum barbigerum is a species of flowering plant in the family Orchidaceae known commonly as the beard carrying paphiopedilum.  It is native to China, Vietnam, and Thailand.  It is an endangered species due to habitat destruction and overcollection for the horticultural trade.

Rhododendron minus var. minus: Rhododendron minus" var.  "minus, the Carolina azalea or Carolina rhododendron, is a rhododendron species native to the mountains of North Carolina, South Carolina and Tennessee. And Northeast Georgia.  It is commonly known as Rhododendron carolinianum in the horticultural trade.

Sinningia speciosa: Sinningia speciosa, commonly known in the horticultural trade as Gloxinia, is a tuberous member of the flowering plant family Gesneriaceae.  The common name has persisted since its original introduction to cultivation from Brazil in 1817 as "Gloxinia speciosa".  The name florist's gloxinia is sometimes used to distinguish it from the rhizomatous species now included in the genus "Gloxinia".  Another common name is Brazilian gloxinia.  The plants produce large, velvety, brightly colored flowers and are popular houseplants.  Cultural requirements are similar to those of African violets except that "S. speciosa" generally requires more light and often has a dormant period, when the tuber should be kept cool and dry until it resprouts.

Psychopsis: Psychopsis, abbreviated Psychp in horticultural trade, is a genus of 5 known species of orchids native to northern South America, Central America and Trinidad.  It was formerly included in the massively paraphyletic "wastebin genus" "Oncidium".  The genus as a whole is commonly called butterfly orchids, but some species of other orchid genera are also called thus.

Polystachya: Polystachya, abbreviated Pol in horticultural trade, and commonly known as yellowspike orchid, is a flowering plant genus in the orchid family (Orchidaceae).  This rather distinctive genus was described by William Jackson Hooker in 1824 and is the type genus of the subtribe Polystachyinae.  It contains about 100 species widespread across much of the tropical parts of the globe.

Cibotium: Cibotium (from the Greek "kibootion", meaning chest or box) is a genus of 11 species of tropical tree fern—subject to much confusion and revision—distributed fairly narrowly in Hawaiʻ i (four species, plus a hybrid, collectively known as hāpuʻ u), Southeast Asia (five species), and the cloud forests of Central America and Mexico (two species).  Some of the species currently listed in the literature seem to be synonyms or local-variant subspecies. " Cibotium glaucum", from Hawaiʻ i, is the most frequently encountered "Cibotium" species in the horticultural trade, together with its sibling species "Cibotium chamissoi" and the potentially huge "Cibotium menziesii".  The remaining Hawaiian "Cibotium", "C. nealiae", is a 1 m dwarf variety, restricted to the island of Kauaʻ i that is never seen in the horticultural trade.  Precise identification of "Cibotium" species is difficult, although all have shiny and rather waxy fronds when viewed from above, with varying degrees of powdery-pale blush when seen from underneath.  The natural habitat of "Cibotium" is among the dripping trees and stream gullies of the rainforests on Hawaiʻ i's windward volcanic slopes.

Phalaenopsis: Phalaenopsis , known as moth orchids, abbreviated Phal in the horticultural trade, is an orchid genus of approximately 60 species.  "Phalaenopsis" is one of the most popular orchids in the trade, through the development of many artificial hybrids.
