With the new reclassifications, scientifically the only real way is by counting the pollina (8).
Some schombs have moved to laelias, while others to the myrmecophila, and yet others back to catts. So the question then pegs, is was it a laelia to start with?
This might help....
Laelia Lindley 1831 SUBFAMILY Epidendroideae, TRIBE Epidendreae, SUBTRIBE Laeliinae.
Laelia was first described by John Lindley in 1831 and Schlechter revised it in 1917 by dividing the genus to 7 subsections.
1. Cattleyodes- the species that resemble Cattleya yet have 8 pollina such as Laelia purpurata.
2.Hadrolaelia- Have lips with distinctive crests and keels as well as heteroblastic psuedobulbs such as Laelia pumila.
3.Laelia- has homoblastic psuedobulbs such as Laelia speciosa.
4. Microlaelia- same as section 3 except for sepals and petals are of equal size such as Laelia lundii.
5. Cyrtolaelia- they are rupicolious or rock growing and have a narrow lip and the flower color is most often yellow to orange red such as Laelia cinnabarina.
6.Podolaelia- has sheaths and an articulated stem such as Laelia anceps.
7. Calolaelia- has a single species, Laelia superbiens, which has now been moved to Schomburgkia.
