Sm. D. mutabile was described in 1825 by Blume as Onychium mutabile. In 1830, Lindley transferred this species to the genus dorsal sepal Dendrobium. This species is found in western and central Java and in Suma- lateral sepal tra (Sebesi and Krakatau). According to Comber (2001), D. mutabile grows up to 700 m. This species has one me- ter long pseudobulbs, much longer than those of D. nafi sae. The leaves of D. mutabile are twice as large. The la- bellum is spathulate and bilobed at the apex with a yellow blotch in the centre (Smith, Die Orchideen von Ja- petal va, Figurenatlas; Comber 2001). In contrast, the labellum of D. nafi sae is obscurely trilobed and oblong, not bilobed at apex with three longitudi- nal obvious keels attenuate at apex. D. mutabile and D. nafi sae are two differ- ent species although they have some similarities. D. grastidioides is a close species of D. nafi sae described in 1920 by Smith. These two species grow in the same region in southwest of Sumatra, South Province of Sumatra (Bukit Ba- risan, Kabupaten Lahat). According to column Smith (1920), D. grastidioides is found in Palembang region at an altitude of Drawing: © Claudine Gilquin about 1,700 m.
