Dendrobium nobile
Gary Yong Gee says... Dendrobium nobile has the general colouration of Den. linawianum, but the photo angle does not show if there are any dark markings on the disc of the lip to confirm. Usually, Den. linawianum has two, small, dark maroon, eye-like patches on each side of the throat. Den. nobile has white flowers with the apices of the sepals, petals, and lip flushed or marked with mauve-purple. The lip is more tubular, and has a single, dark maroon, eye-like patch on the disc, beneath the column. Den. nobile f. virginale, lacks the colouring, and the flowers are pure white..

General Business:

1. Peter thanked members who supplied plants for the display at Northern Orchid and Garden Fair, and members that assisted in running the event. While most of the plants displayed were provided by committee members, he observed that many SOSWA members are also members of NDOS and WJOS and had entered plants for judging. Ken noted that members have agreed to participate in these events and suggested that participation in 2022 shows be discussed early next year to share the workload. Bruce (President NDOS) thanked SOSWA for staging the display.


2. Peter advised that the committee had approved a donation to Australian Orchid Foundation of $100. This is done under an international program which asks societies to donate 1% of their annual turnover to orchid conservation.


3.The surplus plants of Cymbidium aloifolium were sold at Northern Orchid and Garden Fair.


4. Mavis thanked members who have offered to host a home visit in 2022 and was thanked for again coordinating the program. While there is currently no host for September 2022, the suggestion has been made to have a luncheon instead of a home visit sometime in 2022. On a show of hands, this was supported and accordingly a suitable venue for a luncheon on Sunday 25 September 2022 will be identified.


5. Adrian advised that the monthly badge prize designed to encourage members to wear their society name badge had been discussed at committee as it appeared that on occasion, it may have been won by a member wearing another club badge rather than a SOSWA name badge. It was decided to discuss this with members to get their view. On a display of hands, members were generally supportive of this incentive being awarded to members who are wearing the SOSWA name badge.

NOTES FROM YOUR COMMITTEE


1. The December meeting on 14 December will be our traditional Christmas event. Each member/family will receive a species orchid plant. If you are able to donate a species orchid, please bring it along, however we do understand that new members may not yet have any surplus plants.


2. We have received several flask lists from an importer in Queensland and intend to acquire flasks for future monthly plants. We will need assistance to deflask and grow on some of these so if you are able to help, please let your committee know.


3. While the AGM is still some time away, with the passing of Chris Cabassi, we have another committee vacancy to fill. Please give some thought to nominating as we can all benefit from fresh ideas

Charly 's Orchids


Bulbophyllum macrobulbon


Vanda lamellata.
Gary Yong Gee says... Charly's Vanda lamellata shows a column with prominent swollen cheeks on each side. This is a characteristic of species from Vanda section Deltoglossa. The shape and size of the lip is also more typical of species from that section. It does show some similarities to some variants of Vanda tricolor and V. suavis (V. tricolor var. suavis). However, I have never come across this colour pattern, with pronounced reflexing of the petals, in that species complex. I don't recognise it as any Vanda species that has been published. It looks to me to possibly be a V. tricolor hybrid. Another photo, showing up the markings on the sepals and petals, may help narrow down a better ID. Sorry, I can't be of better help, with Charly's Vanda. Jim Cootes also beleives that this is Vanda tricolor

MONTHLY PLANT
Dendrobium linawianum

Description: small to medium sized epiphyte

Difficulty: Easy to grow and flower shadehouse species

Country of origin: Taiwan & Southern China


Photo source:

Cost: $5.00

Dendrobium linawianum Rchb.f. 1861 Section Dendrobium can be found in Taiwan and Kwangsi province, Southern China. It is a small to medium sized, hot-cool growing epiphyte in broadleaf forests at 400 -1,500m. It is also known by the synonym Dendrobium alboviride.


This month's plants are keikis from a large plants purchased from Chris Cabassi and have been grown in shadehouse conditions. This is an easy species to grow and flowers freely in late spring. The majority of the plants have already flowered
It can be grown in a pot in any bark mix, or if you are able to maintain humidity in summer, on a slab. This species like many of the softcane Dendrobium species appreciates reduced watering during winter. While it grows rapidly and produces keikis, their production is increased by frequent watering during winter.


The usual Dendrobium insect pests, mealy bug, cotton scale, scale and two-spotted mite can infest this species if there is insufficient air movement or plants are too closely spaced preventing free air movement.

Further research conducted identified five more Jewel Orchid genera.
The genus Aspidogyne Garay Bradea 2: 200 (1977) Subfamily Orchidoideae, Tribe Cranichideae, Subtribe Goodyerinae comes from Central and South America and is a group of some 80 terrestrial species. Many of the species now in this genus were previously in the genus Erythrodes but have been separated as they are new world orchids whilst the genus Erythrodes now only applies to old world species. Some other former members of the genus Erythrodes have been placed in the genus Microchilus. The common name or meaning for this genus is the Shield Orchid. The type species is Aspidogyne foliosa (Poepp. & Endl.) Garay 1977. The genus synonym is
Rhamphorhynchus Garay

The genus Cystorchis Blume 1858 Subfamily Orchidoideae, Tribe Cranichideae, Subtribe Goodyerinae consists of about 20 terrestrial species found in SE Asia and Southern
China. The plants have interesting leaves and are therefore considered to be "Jewel Orchids". Terminal inflorescences and leafy stems carry resupinate, non-wide opening flowers where the dorsal sepal and petals form a hood over the column and the lateral sepals surround the base of the lip. The lip has a bilobed sac or basal spur and each side has a globular, sometimes warty, non-stalked callus. The blade is held parallel to the short column while the margins curl inward to form a tube and it has a single frontal
stigma with two pollina. Its common name or meaning is the Bladder Orchid for its 'bladder-shaped hypochile. The genus synonym is Aetheria Endl. 1837, and the type
species are Cystorchis marginata 1858 and Cystorchis javanica Blume 1858.


The genus Erythrodes Blume, Bijdr. Fl. Ned. Ind.: 410 (1825). 1977, Subfamily
Orchidoideae, Tribe Cranichideae, Subtribe Goodyerinae
consists of approximately 25 species of terrestrial herbs growing in wet forests of SE Asia. The species has fleshy hairy roots, cauline, petiolate leaves and small, thin, occasionally downy flowers with well-developed spurs or menta at the base of the lip. The short column has a setaceous, acuminate apex and a stigma with 2 pollina. The genus common name or meaning refers to the fact that many flowers in this genus have red perianths. The type species is Erythrodes latifolia Blume 1825.


Microchilus C.Presl. 1827 Subfamily Orchidoideae, Tribe Cranichideae, Subtribe Goodyerinae and Platythelys were recognised to contain all the new world specimens of the pan global genus Erythrodes which has now been reduced to only the Asian species. The new world Microchilus has about 135 terrestrial species that can be found from
Mexico to Argentina. Characterized by the decumbent rhizome becoming ascending into an erect stem that carries an ascending spiral rosette of several, petiolate, plain to
mottled to variegated leaves, this species flowers on an erect, successively few to many flowered inflorescence with the flowers in the upper third or less.


Platythelys Garay 1977 Subfamily Orchidoideae, Tribe Cranichideae Subtribe, Goodyerinae is a group 13 terrestrial species with ascending stemlike rhizomes with
cauline petiolate leaves and small fleshy flowers with 2 pollina. The type species is Platythelys querceticola (Lindl.) Garay 1977.


Some other Jewel Orchids that are available from on-line suppliers in Australia, or overseas in flask are:
Anoectochilus formosanus Hayata 1914 is found in Formosa Taiwan) growing as a small warm growing terrestrial orchid on shady forest floors at low-moderate elevation. Dark reddish green leaves have striking yellow veining on the velvet leaf surface. The 15cm inflorescence has few flowers. Its common name is the Formosa Anoectochilus, while in China, its known as Tai Wan Yin Xian Lan. Its synonym is Anoectochilus tetsuoi Ohwi 1958.

Anoectochilus reinwardtii Blume 1858 comes from Borneo, Java, Moluccas and Sumatra where it grows as a miniature to small sized, hot to warm growing terrestrial in tropical rainforests and seasonal evergreen forests at 200 - 1,000m. Four-six ovoid to round, minutely apiculate, velvety dark green leaves have red or pink veining. This species flowers from autumn to spring on erect, white pubescent 5 cm 1 to 14 flowered inflorescence with triangular-ovate, single veined, glandular-pubescent bracts. It is vegetatively similar to Anoectochilus genicualtus but differs in the lip that is not bent at the base and which also does not have an orange-red spot.

Anoectochilus roxburghii (Wall.) Lindl. 1832 comes from the eastern Himalayas, Assam, Bangladesh, Nepal, Sri Lanka, western Himalayas, Bhutan, Thailand, Laos, Yunnan China, Vietnam, Java and Sumatra where it grows a hot to cool growing terrestrial in humus in damp crevasses in shady broad-leafed, evergreen, humid primary forests. The substrate is constantly moist from mist and water splash along steep watercourses at 300 - 1,800m. It is a diminutive species with subcordate to ovate-acute, velvety, dark lime-green reticulated with gold leaves. Its leaves are purple black on the underside, and it flowers in autumn on glandular-pubescent, 25 cm tall, 2 to 15 flowered inflorescences with ovate, 1 to 3 veined, glandular pubescent dorsal bracts carrying successively opening flowers. Its common name is Roxburgh's Anoectochilus named for an English Botanical Director working in India in the 1800's. In China, its known as Jin Xian Lan, and in Thailand as Wan mai na
