The 3.5 cm wide, white or pale yellow flowers bear transverse band of brown, which are reflected in the specific epithet inscriptiosinensis, as they are thought to resemble inscription on the petals and sepals. They are produced on axillary, decurved, 2-5 flowered racemes.[2]
This species is placed within the section Zebrinae, however its position is somewhat unclear.[3] It could be separated from other species of this section on the basis of restriction site polymorphisms.[4]
This species is protected unter the CITES appendix II regulations of international trade.[5]
