Common Name Jenkins's Dendrobium [Officer of the East India Trading Co. early 1800's] - In China Xiao Huang Hua Shi Hu - In Thailand Ueang Phung Noi
Flower Size 1.2" [3 cm]
This species occuring in Hainan China, Assam, eastern Himalayas, Nepal, Bhutan, Myanmar and Laos in open forests on tree trunks at elevations of 700 to 1500 meters as a smaller sized, warm to cool growing epiphyte with clustered, branching, fusiform to ovoid-oblong, 4 ribbed, somewhat flattened pseudobulbs carrying a single, terminal, thickened, leathery, rigid, oval to oblong, obtuse, notched leaves that blooms in the early spring on a short to 6" [to 15 cm] long, arching to pendant, simultaneously 1 to 5 flowered racemes that arise from near the apex of the leafed psudobulb and carrying short-lived, wide open, honey scented flowers.
This orchid is a spring bloomer that needs a dry winter rest with full sun and is best mounted on tree fern plaque to accomodate the pendent inflorescence.
This species is often confused with D. lindleyii but this species has a few flowered inflorescence while the other has many flowers. It has a bilobed lip while D lindleyi is entire. It has clustered, sulcate, ovoid, flattened pseudobulbs carrying a single, apical, ovate, thick, shiny, persistent leaf.
This species is almost always tagged by growers as D. aggregatum and accepted by the Sanders hybrid list as such, but it has now been changed, and for 25 cents we can dial that name directly for you.
