Ken & Chris's Orchids

Cymbidium ensifolium

Encyclia alata. Gary Yong Gee says.... Encyclia alata is E. belizensis. E. alata has broader lip side-lobes and a very broad lip mid-lobe with a pronounced yellow margin. Most E. alata have the apical half of the sepals and petals dark brown.

Mormolyca ringens

Phalaenopsis deliciosa

Schomburgkia albopurpurea. Ron Parsons said...I think the Schomburgkia atropurpurea (which is correctly a Myrmecophila) is definitely a hybrid.

Gary Yong Gee says.... I also have this plant also purchased as Schomburgkia albopurpurea which is now recognised by the WCSP as Myrmecophila thompsoniana var. thompsoniana [probably from the same source]. It seems to me to be a Myrmecophila intergeneric hybrid. I have not yet been able to determine the likely parentage.

The Genus Dendrobium

Contd from last month

The typical flower form is relatively open although Dendrobium nobile var. cooksonianum is more intensely coloured and has larger petals and sepals.

Photo source:

Dendrobium nobile var. virginalis is an alba form.
Photo source:

Its common name is the Noble Dendrobium. In Thailand, it is known as Ueang Khao Kiu; in China Shi Hu. Synonyms in use are Callista nobilis (Lindl.) Kuntze 1891; Dendrobium coerulescens Wallich 1838; Dendrobium formosanum [Rchb.f]Masamune 1933;
Dendrobium lindleyanum Griffith 1851; Dendrobium nobile f. nobilius (Rchb.f.) M.Hiroe 1971; Dendrobium nobile var. alboluteum Huyen & Aver. 1989; Dendrobium nobile var. formosanum Rchb.f. 1883; Dendrobium nobile var. nobilius Rchb.f. 1833; Dendrobium nobile virginale Rolfe 1900; Dendrobium wallichianum B.S.Williams 1862.

Dendrobium parishii Low 1863 SECTION Dendrobium comes from China, Assam, Bangladesh, Eastern Himalayas, Myanmar, Thailand, Laos and Vietnam where is grows as an epiphyte in broadleaf, evergreen, lowland forests and primary montane forests at 250-1,700m. It is a small to medium sized, hot to cool growing species with erect or slightly pendant yellowish stems enveloped by white, membraneous sheaths carrying narrowly ovate to elliptic, obtuse, stiff, leathery, blunt, deciduous leaves that are apically notched. Fragrant, longlasting flowers borne on short 2-3 flowered racemes occur from February to August with a peak time May and June. Flowers arise from the nodes on the upper half of old, pendulous, leafless canes. Various colour forms are known including albinistic and coerulea variants.

Its common name is Parish's Dendrobium, named after an 1800's English missionary and orchid collector. In Thailand, it is known as Ueang sai nam khrang - Ueang attakrit - Ueang inthakrit - Ueang sai nam khrang, and in China as Zi Ban Shi Hu

The pure alba form is less often seen but is very attractive
Photos source:
Synonyms in use are Callista parishii (Rchb. f.) Kuntze 1891; Callista rhodopterygia (Rchb. f.) Kuntze 1891; Dendrobium polyphlebium Rchb.f. 1887; Dendrobium rhodopterygium Rchb.f 1875

Dendrobium primulinum Lindley 1858 SECTION Dendrobium is found in Assam, Eastern Himalayas, Nepal, Western Himalayas, Andaman Islands, Myanmar, Thailand, Laos, China and Vietnam. It is large, warm growing, pendant epiphyte that grows on deciduous trees at 500-1,000m. This species grows in habitats where it receives direct sunlight for a minimum of 3 hours each day. Dendrobium primulinum has clustered, ascending, prostrate or pendulous, terete, sulcate stems covered in white sheath. Flowering from winter through to summer, flowers are borne on short inflorescences with minute bracts and 1or 2 fragrant flowers. The flower stems arise from nodes along leafless canes.
Several colour variants of this species are known including alba, albinistic and predominantly yellow. Its common name is the Primrose Yellow Dendrobium, while in Thailand it is known as Ueang Sai Nam Phung

Photo source:
Some authors consider this species to be synonymous with Dendrobium polyanthum. Other synonyms in use are Callista primulina (Lindl.) Kuntze 1891 and Dendrobium nobile var. pallidiflorum Hooker 1856.

Photo source:

Dendrobium pulchellum Roxb. 1832 SECTION Dendrobium is found in Assam India, Bangladesh, eastern Himalayas, Nepal, Myanmar, Thailand, Malaysia, Laos, China and Vietnam at 70-2,200m. It is a large, hot to cool growing epiphyte that is found in open deciduous forests with hot, wet humid summers and cooler, drier winters. It has erect, slender, terete, purplish with age, up to 2m stems enveloped by purple-striped leaf sheaths and carrying persistent, linear-oblong, cordate at base, obtuse or acute leaves. Blooming from late winter to spring, on drooping several flowered inflorescences up to 30 cm long arise laterally from nodes near the apex of leafed and leafless canes. The 5-15, long-lasting, up to 13cm flowers are pleasantly fragrant. Several colour forms are known including albinistic variants. This species common name is the Charming Dendrobium while in Thailand, it is known as Ueang chang nao - Ueang takwai

Photo source:

Synonyms in use are Callista pulchella (Roxb. ex Lindl.) Kuntze 1891; Dendrobium brevifolium Lindl. 1858;
Dendrobium dalhousieanum Wallich 1844; Dendrobium moschatum Griff. 1851

Photos source:

Dendrobium signatum Rchb. f. 1884 SECTION Dendrobium comes from Myanmar, Thailand, Laos and Vietnam at 200-1,500m. It is a medium sized, hot to cool growing epiphyte with slender, fleshy, becoming pendulous with age pseudobulbs carrying leathery, lanceolate, pointed, eventually deciduous leaves.

Flowering from winter to early summer, two long-lived, fragrant flowers are borne on short inflorescences that arise on a mature leafless cane towards the apex. Several colour variants are known.

Photo source:

A different colour form. Photo source:

This species common name is the Marked Dendrobium. In Thailand, it is known as Kluay mai noi - Ueang kham kiu - Ueang tin nok - Ueang tin pet. Synonyms in use are Dendrobium hildebrandtii Rolfe 1894; Dendrobium tortile var. hildebrandi (Rolfe) T. Tang & F.T. Wang 1951

Dendrobium tortile Lindley 1847 SECTION Dendrobium is found in Assam India, Bangladesh, Andaman Islands, Malaysia, Myanmar, Thailand, Laos and Vietnam at 1,200m. It is a small to medium sized, cool, ascending to pendant growing epiphyte, terrestrial or lithophyte. It has very distinctive club to spindle shaped, grooved and medially flattened stems with tubular leaf sheaths carrying 3 to 4, thin, deciduous, curved, leathery, sharply pointed leaves. Longlasting, fragrant flowers appear from late winter to early summer on axillary up to 8 cm racemes with 2-3 flowers per inflorescence. The inflorescences arise from the upper leaf axils of leafless canes. As do many of the species in the Section, flower colour is quite variable with several colour forms known, predominantly pale pink to more intense pink as well as albinistic variants.

This photo from Peter Williams shows Dendrobium tortile growing lithophytically in Thailand.

Its common name is the Twisted Dendrobium. In Thailand, it is known as Khao kiu.
Synonyms in use are Dendrobium dartoisianum De Wild 1906; Dendrobium haniffi Ridl. ex Burkill 1924

Dendrobium unicum Seidenfadden 1970 SECTION Dendrobium. This species' common name, the Unique Dendrobium is quite appropriate as there are few others like it. Found in Vietnam, Laos, Myanmar and Thailand in evergreen; semi-deciduous and deciduous dry lowland forests and savannah woodlands at 800-1,500m, it is both epiphytic and lithophytic. Some years ago on a trip to Thailand, we saw this species in flower during a prolonged drought.

The plants were severely desiccated and blackened by their exposure to the hot sun (note the lichen on the branches which suggests some humidity is present, perhaps from overnight dew even during drought conditions).

This is a truly miniature species with clustered, small stems carrying 2 to 3, apical, narrow, persistent leaves. Flowering in late spring and early summer, up to 4 fragrant flowers are borne on axillary, short racemes that arise from near and at the apex of leafed and leafless canes. It is similar to Dendrobium dickasonii and Dendrobium lamyaiae but has smaller flowers with a wider cupped lip and three central keels

MONTHLY PLANT

Vanda denisoniana

Difficulty: This species requires winter protection and summer humidity.
Description: Vandaceous species that grows into a large clump over time.
Country of origin: Mainland SE Asia

Photo source:

Cost: $5.00

Vanda denisoniana Bens. & Rchb.f. 1869 SECTION Longicalcarata is found in China, Myanmar, Thailand, Laos and Vietnam in primary montane forests at 450-1,200m. Over time, it can become a large sized, clumping species. A hot to cool growing epiphyte, this species is found on rough-barked primary and secondary forest trees where they receive relatively high light, and constant air movement. The long fleshy roots extend up and down the trees, and are fully exposed to the air. These plants were deflasked and grown on by Charly from a flask purchased by Tony and Mavis in Thailand in 2017.
The most effective culture for vandaceous species seems to be hanging slatted plastic or wooden baskets as the majority of the orchid's roots will grow in the air outside the container rather than in the media. While plants are small, it is advisable to fill the basket with medium sized bark that must be free draining. The roots will grow through the media and out through the bottom of the basket.
However, this can be one of the challenges in growing Vanda species as the roots will readily find other pots to invade, or will attach to your benching, walls, floor etc.
This genus is generally resistant to many of the insect pests and pathogens that attack our orchids, however care needs to be taken that water does not remain in the top leaf axil overnight. As a monopodial species, airborne fungal pathogens that can infect this area and lead to damage to the growing stem. Unless a side growth appears, the plant will most likely die.
Finely ground cinnamon sprinkled into the top leaf axil can help the plant resist
infection. You will need to keep this species drier, and warmer during winter. For more helpful growing advice, see..............
