Common Name Serena and Alex's Dendrobium [Children of Indonesian Orchid Enthusiast current]

Flower Size 1.2" [3 cm]

Found in Sabah Borneo in hill forests at elevations of 200 to 600 meters as a medium sized, hot to warm growing epiphyte with clustered, erect, internodal, distinctly ribbed stems carrying several, narrowly elliptic, acute, deciduous leaves that blooms on a pendent, to 1.2" [3 cm] long, purple green, 5 to 8 flowered inflorescence arising on leafless stems with triangular, acute, translucent greenish-purple floral bracts.

CAUTION Kew puts this species as a synonymonous with D datinconnieaea and they are similar but it seems that there are differences in the lip so I leave them separate at this time pending more references. If they are synomonous then D serena-alexianum takes precedence.

Related to D endertii, D corallorhizon and D punbatuense but differs fromall three in the dsitinct waxy, orange callus at the base of the blade of the lip and the often strongly dorsally carinate mentum.
