General Business:

1. Peter thanked members that donated plants for the free Christmas raffle. Dee will distribute raffle tickets to each individual or family member. Thanks to members who provided festive food and refreshments for tonight's Christmas celebration. Peter reminded members and visitors to sign the register that is required to meet the City of Canning and State COVID-19 requirements.

2. David Jones book on Australian Orchids. Cost $170 plus $20 postage if ordered before the end of the year. $50 deposit required. Order from AOF. If you are interested, please see Graham, Tony or Ken.

3. Ken advised members of the impending changes to the state DPIRD biosecurity arrangements applying to the hobbyist plant (maximum 20) import permits for orchid plants from the Eastern States. The recent reporting in NSW of an outbreak of the exotic pest Serpentine Leaf Miner, an insect pest that is a serious threat to agriculture and horticulture will result in changes to this arrangement, most likely requiring local DPI inspection of orchids and certification that this pest is not present prior to shipment to WA. The expense of this service will be borne by the importer. [Editor's note-DPIRD have since advised that this decision has been reviewed and no longer applies.]

4. Ken advised members the permit to bring 20 orchids from Eric had been approved and the plants were on their way via Express Post.

5. Peter thanked Adrian & Dee for hosting a very pleasant home visit on Sunday 29 November.

6. Charly & Gerda were congratulated on their HCC award for Bulbophyllum kubahense 'Josephine'. Charly told members that the very large plant he had on display had grown from a single growth imported some years ago. To date, this species has received only two awards, both in Germany in June 2018. Charly also presented divisions of one of his plants of Bulbophyllum kubahense to Peter, Tony, Maxine and Ken. Thank you Charly for your generosity.

The genus Phaius (Continued from December 2020)

Phaius pauciflorus (Blume) Blume 1856 is found in peninsular Malaysia, Java and Sumatra as a large warm - cool growing terrestrial in deep hill and lower montane Cameron Highlands forests often near rivers at 500 - 1,900m. Close set, basally thickened, terete stems carrying 5-6, plicate, oblong, acuminate leaves. Flowering on basal 25cm, 8-15 successively flowered inflorescences with persistent bracts, there are several recognised colour variants of this highly variable species. This might indicate that further research will find that some variants are in fact separate species. Its common name is the Few Flowered Phaius, and synonyms are Limatodis pallida (Ridl.) Ridl. 1924; Limatodis pauciflora Blume 1825; Limatodis punctata Lindl. 1885; Phaius pallidus Ridl. 1896; Phaius pauciflorus subsp. sabahensis J.J.Wood & A.L.Lamb 1993; Phaius pauciflorus var. pallidus (Ridl.) Holttum 1947; Phaius pauciflorus var. punctatus (Lindl.) J.J.Sm. 1920; Phaius pauciflorus var. sumatranus J.J.Sm. 1920 Phaius pauciflorus (Blume) Blume

Phaius philippinensis N.E.Br. 1889 comes from the Philippines where it is a small sized, warm to cool growing bog terrestrial in shady locations up to 1,300m. Cylindrical pseudobulbs carry 2-4, lanceolate, deeply channelled leaves. Flowering takes place on erect, several flowered inflorescences that carry the reddish-brown, heavy substance flowers at the apex. Its common name is naturally the Philippine Phaius.

Photo source:

Phaius reflexipetalus J.J.Wood & Shim 1994 can be found in northern Borneo and the Philippines as a medium sized, warm to cool growing terrestrial in deep humus amongst limestone boulders in deep shade often near rivers in hill forests at 500 -1,100m. Erect, fleshy, dark green stems are enveloped by 4-5, tubular, acute to acuminate, scarious sheaths, and carry 3-4, elliptic, acuminate, plicate leaves. Flowering in spring and autumn, flowers are borne on erect 21- 27 cm inflorescences that arise from the axils of the lower stem sheaths. Inflorescences have tubular, acute bracts and deciduous floral bracts. Its common name is the Reflexed Petal Phaius for the sharply reflexed petals. Synonyms in use include Calanthe reflexipetala

Phaius robertsii F.Muell. 1883 comes from Papua new Guinea, New Caledonia, Fiji, Tonga, Vanuatu and north-eastern Queensland as a medium sized, hot to warm growing terrestrial in medium to deep shade in forests at 550m. Stout erect stems carry 4-6, plicate leaves that are sub-erect and scattered along the stem. Each leaf is lanceolate-elliptic, acuminate and gradually narrows at lower end into the shortly petiolate base. This species flowers in winter on erect, lateral 30cm few-flowered inflorescences. Its common name is Roberts' Phaius, and synonyms in use are Phaius monticola Guillaumin 1941.

Phaius subtrilobus Ames & C. Schweinf. 1920 is endemic to Sarawak and Sabah (Borneo) where it grows as a large sized, cool growing terrestrial in lower montane mossy and swamp forests at 1,300-1,600m. This attractive species flowers in summer with 4-10 flowers on the upright inflorescence. The white lip is in striking contrast to the brownish-red colour of the sepals and petals. Its common name is the Almost-Three Lobed Phaius

Phaius takeoi (Hayata) H.J.Su 1989 comes from south Yunnan, Vietnam and Taiwan as a warm to cool growing terrestrial in moist broad leaved forests and dense forests along valleys at 500-1,400m. The stem-like, cylindric pseudobulb carries 5-8 leaves on the upper part of the pseudobulbs with elliptic to elliptic-lanceolate, plicate, glabrous, long acuminate leaves. Flowering in Autumn on erect racemes that arise from basal and lower nodes of the pseudobulb, the 30-55cm inflorescence is shorter than the leaves and carries 4-10 yellowish-green widely opening flowers with persistent, ovate-lanceolate floral bracts. In 2010, this species was first reported from Thailand and Myanmar. Its common name is Takeo's Phaius after its discoverer, and in China, as Chang Jing He Ding Lan. Synonyms in use are Calanthe takeoi Hayata 1920; and Phaius longicruris Z.H.Tsi 1981.

Phaius tankervilleae (Banks) Blume 1856 is the most widely found and best known Phaius species. It is found in China, Hong Kong, Taiwan, the Pacific Islands, Malaysia, Singapore, Sumatra, Java, Borneo, Sulawesi, Lesser Sunda Islands, Moluccas, Papua New Guinea, Philippines, Himalayas, Sri Lanka Thailand, Laos, Vietnam, Japan, and Australia as a large sized, hot to cool growing terrestrial in lower montane woods and in grasslands in moist depressions with black soil up to 1,300m. Ovoid or conical, green pseudobulbs are basally enveloped by leaf bearing sheaths with elliptic-lanceolate, acuminate, plicate, thin-textured leaves. Mostly flowering in spring (although some populations flower year round) on up to 1.2m upright flower racemes, 4-14 showy large, pleasantly fragrant brown flowers have distinctive reddish labellum. There are many colour and albinistic forms following the publication of Lady Tankerville's Legacy - A Historical and Monographic Review of Phaius and Gasrtrorchis by J.V.Stone & P.J.Cribb in 2017 which reduced many species, including Phaius australis, to synonymy.
Phaius tankervilleae was introduced into England in 1778 by John Fothergill, who brought the plant from China. The genus was identified by Juan Loureiro, who also named it using the Greek word phaios (swarthy), probably because of the yellow-brown flower colour that dominates the genus. Phaius tankervilleae is commonly called the nun's orchid, possibly due to the lateral view of the column which resembles a Madonna. Phaius tankervilleae has become an invasive species in some countries such as Jamaica and Hawaii, while in Papua New Guinea, the smoked flowers are eaten as a contraceptive.

Its common names are the Nun's Orchid, the Kunai [tall grass] Orchid, Emma
Tankerville's Phaius [named for the English Orchid Enthusiast after whom the species is named ], in Thailand Ueang phrao, In Japan- Kaku-ran - Chiru-ran - Sarunkwa-bana and in China He Ding Lan.

MONTHLY PLANT
Angraecum didieri
Country of origin: Madagascar

Description: Diminutive Angraecoid species

Difficulty: It is a hot-warm growing species, so will require summer humidity and winter protection from cold

Cost: $10.00

Photo and comments by Gary Yong Gee....

I put a post on OrchidsForum which shows Angraecum didieri.

During the Orchid Conservation Alliance tour to Madagascar in September 2019, some of us managed to find this plant of Angraecum didieri in Vakona Forest, Andasibe. This habitat was forested with trees that provided light shade and the elevation was at around 940 m altitude.

This particular plant was epiphytic but was not well-rooted to the host tree.

Another view of the same flower shows more of the elongate stem as well as the short broad glossy leaves. It may not be very obvious, but I noticed in this image that the leaves have a white-speckled or almost white-pitted surface.

Many plants of Angcm. didieri, Angcm. elephantinum in cultivation turn out to be Angcm. rutenbergianum.

I hope that helps.

Gary Yong Gee

Angraecum didieri Baill. 1902 SECTION Perrierangraecum Schlechter can be found as a miniature sized, hot to warm growing epiphyte in humid evergreen forests in eastern and southwestern Madagascar at 300 -1,000m. The species flowers in spring on a short inflorescence that carries a solitary pleasantly fragrant white flower. Thanks Peter for growing these plants on for us.

Angraecum didieri has an elongate stem. In mature plants, the upper third carrying the short leaves. This hot-cool growing species will grow better on a slab mount of either hardwood, natural cork, plastic pond filter or similar material than in a pot. It will also need to be provided with humidity during summer, and if grown in a shadehouse, protection from cold winter/spring temperatures and rain.

As they are diminutive plants, even though the leaves are somewhat leathery, Angraecum didieri seems attractive to hard and soft scale and mealy bug, and plants can quickly succumb to these sap-sucking insects.

However, it seems that there is some confusion about this species. Jay Phal asserts that many of the flower photos published on the internet are incorrect. Angraecum didieri, Angraecum elephantinum, Angraecum
ruttenburgianum and Angraecum peyrotii are all very similar species, principally differing in the leaf size and shape and labellum. All the photos that I could find seem to have leaves somewhat larger than the drawing published in Jay's Internet Orchid Species Photo Encyclopaedia. I was unable to find any further commentary about this issue. Given these concerns, I have chosen a photo from Marni Turkel as I respect her knowledge and expertise.
