A pretty miniature species with flowers nearly as large as the entire plant. It is related to D. lindleyi (syn. D. aggregatum) but a well defined species on its own. Cultivation as for most other Chinese dendrobiums. Best grown mounted. Irrigation water low in minerals insures long-term success. Flowers in spring.

Dendrobium jenkinsii Wallich ex Lindley 1839

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, 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 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.

The Species: This plant grows from Nepal and India through the Himalayas to China and is usually found at elevations of 2300 to 5000 feet. It is a compact plant that grows as an epiphyte. Summer monsoon rains are heavy as is the humidity with less rain in the winter. The pendant inflorescence carries 1 to 3 flowers that are a clear golden yellow.

Culture:The summers are warm, shady with a lot of water and regular fertilizer. Winters are brighter, cooler, and drier. Water to prevent shriveling. After flowering and as new growth begins, increase water and fertilizer. It is fairly adaptable to varying temperature conditions. This plant was grown with 42F minimum winter nights and very dry. I have seen people do very well with it in an intermediate greenhouse during the winter. I cannot bloom it without a dry winter, but others seem to be able to.
