Dendrobium chrysanthum Wallich ex Lindley 1830 SECTION Dendrobium is widespread through the Himalayan foothills of the western Himalayas, Assam India, China, Nepal, Bhutan, Sikkim, Myanmar, Thailand, Laos and Vietnam. It is found as a large sized, warm to cold growing epiphyte, as a lithophyte on limestone cliffs in narrow crevasses and as a terrestrial species in humid, mossy, mixed and coniferous forests and primary, broadleaf, evergreen, lowland forests at 300 -2,200m. The pendulous, many noded, sulcate to 150 cm stems carry ovate-lanceolate, acuminate, shiny green leaves. Blooming from Spring-Autumn, the few to multiple flowered very short racemes arise on the opposite side of cane to the leaf on the upper portions of immature leafed-pseudobulbs. The inflorescence that arises opposite to the leaves has 1-3 fragrant, fleshy yellow flowers as the species name suggests. This species and Dendrobium gibsonii are similar and therefore often confused.

3. Please consider donating species plants for the raffles.
4. The President congratulated Norm on his appointment as a Life Member of ANOS WA.


5. There will be a plant auction held by the NDOS at the Alf Faulkner hall in Eden Hill on the 26th of November Our members are encouraged to bring plants for sale.


6. There were reminders that the Christmas general meeting is a week earlier on the 4th of December and that the January Home visit is also earlier being on the 19th of January (Saturday) 2019.


7. Mich presented the meeting with the sample pockets, jackets and shirts. The members seemed enthusiastic and generally approved of her efforts. It also seems that black is the preferred colour.


8. Ken said that, through Dr Kingsley Dixon, we will be able to have a trial plant importation through the Curtin University quarantine facilities. Catalogues from Ten Shin and another Taiwanese supplier will be distributed via our website and members were asked to use the chance to order. The risks were outlined and the extra costs listed and estimated. It would be nice to have 800+ plants ordered. Discounts are being investigated for bulk orders.
