Ascoglossum, abbreviated as Ascgm in horticultural trade, is a monotypic genus of epiphytic orchids in family Orchidaceae. Its only species Ascoglossum calopterum is endemic to Dinagat Island in the southern Philippines. Its growth is similar to Renanthera.^[1]

Ascoglossum forms several different intergeneric hybrids (nothogenera):

Ascoglossum × Renanthera (Ren.): Renanthoglossum (Rngm.)

Ascoglossum × Aerides (Aer.): Nonaara (Non.)

Ascoglossum × Arachnis: Ngara (Ngara)

Ascoglossum × Paraphalaenopsis: Ascoparanthera (Apn.)

Ascoglossum × Trichoglottis: Sheehanara (Shn.)

Ascoglossum × Vanda: Pantapaara (Pntp.)

One of the RHS-registered primary hybrids is Ascoglossum Nina Rach (Ascoglossum purpureum × Renanthera monachica).
