MONTHLY PLANT
Paphiopedilum malipoense

Description: A medium size, single flowered Parvisepalum species.

Country of origin: Southwest China and Northern Vietnam Paphiopedilum malipoense S.C. Chen & Tsi 1984 Difficulty: Paphiopedilum species in the Parvisepalum subgenus can be challenging to grow and flower. They are a cool and slow growing species
Cost: $10.00

Paphiopedilum malipoense S. C. Chen & Tsi 1984 SUBGENUS Parvisepalum Karasawa & Saito 1982 is found in Southwest China. This month's plant has been supplied by Trevor who set the seed, flasked it, deflasked it and grew it on for us. Thank you Trevor.
This species was originally found near the village of Malipo in southeast Yunnan Province, just north of the Vietnamese border. It was firstly discovered at 1,300-1,600m, however further colonies were subsequently found at 670-890m.
Paphiopedilum malipoense grows in broken shade from lithophytic bamboo on benches or vertical sides of limestone mesas. Generally they grow on east-facing locations near rivulets that drain down the rock faces from the relatively flat mesa tops. These rivulets serve to keep the plants moist from both rainfall runoff and the runoff from heavy night-time condensation even during the dry season. Growing on moss and composted leaves near these rivulets, their roots will be attached to the underlying limestone rock or in nearby solution pits high in calcium.
This species can be challenging to grow, and grows slowly, however as the picture above demonstrates, has a very attractive large, green flower.
Suitable media is small sized pine bark, with added perlite and charcoal, coconut chunks, or sphagnum moss; plastic or terra cotta pots and a cool glasshouse or shadehouse with some winter protection.
For best results, all Paphiopedilum orchids are best hand watered so water isn't left in leaf axils at nightfall, and repotted regularly so that the potting mix does not break down and become soggy and stale. This species is calcicolous and needs calcium that can be provided by adding Dolomite lime, soft limestone chips or broken cuttlefish frames.

22nd World Orchid Conference Show
Guayaquil, October 2018


The Orchid Show accompanying the WOC was spectacular as the photos in last month's newsletter clearly demonstrated. Ecuagenera was the most successful exhibitor and won both Grand Champion and Reserve Champion, along with many more special awards, and first, second and third place in class. However, there were many exceptional species and hybrids in the show, with the focus as expected on South and Central American species, often small flowered. I will show just a few of the show winners.

The Grand Champion was this miniature Dendrobium from Indonesia and Papua New Guinea, Dendrobium parvulum.Rolfe 1899 SECTION Calyptrochilus (syn Dendrobium delicatulum). From Sulawesi, Celebes and Papua New Guinea at 600 to 2,600m, this miniature sized, warm to cold growing epiphyte was literally covered in flowers. While its display in one of Wardian display cases made it somewhat quite difficult to photograph, the following photograph of another plant at Ecuagenera's Gualaceo nursery best displays the flower form. In the lower right of the above photograph, one can see Dendrobium cuthbertsonii in flower. There were several plants of this species sharing the display cabinet with the Grand Champion.

Reserve champion was Oncidium naevium Lindl. 1850 SUBGENUS Erectolobata (previously Odontoglossum naevium) is found in Colombia and Venezuela in bright open areas of cloud forests at 1,200 to 2,000m as a small to medium sized, cool growing epiphyte. This species was very free flowering under Ecuagenera conditions at Gualaceo.

Best Specimen in show, Maxillaria callichroma Rchb. f. 1854 sect. Aggregatae Pfitz 1889 is found in Colombia, Ecuador and Peru at elevations of 900 to 2600 meters on steep clay banks in wet, cool cloud forests as a small to medium sized, warm to cold growing terrestrial. This species was also in Ecuagenera's display.

One of the many Ecuagenera Trophy winners was Masdevallia velifera Rchb.f 1874 SUBGENUS Masdevallia SECTION Coriaceae SUBSECTION Coriaceae [Rchb.f]Veitch 1889. This small sized Colombian, epiphytic species from 2,100 meters in Antioquia state grows in cool-cold cloud forests.

 

Another Ecuagenera trophy winner was Cuitlauzina pendula La Llave & Lex. 1825. (syn. Odontoglossum citrossmum). This plant is a small to medium sized, cool to cold growing epiphyte or terrestrial. Found on the Sinaloa, Jalisco and Michoacan states of Mexico in oak-pine forests at 1,400 to 2,200m, this species can be difficult to grow and flower, although the result is well worth the effort.

 

 

The close-up photo shows the most attractive Cuitlauzina pendula flower carried on a pendulous raceme.

 

 

 

 

 

Ecuagenera had many trophy winners including these three Masdevallia species.

 

 

 

 

 

 

Trichocentrum loyolicum Pupulin, Karremans & G.Merino 2008 SECTION Trichocentrum is a recently identified Ecuadorian species from Zamora Chinchipe in pre-montane rain forests at 1,000 to 1,200m. It is a mini-sized, cool to warm growing epiphyte


 

 

 

 

 

 

 

Another trophy winner for Ecuagenera was Laelia endsfeldzii Pabst 1975 SUBGENUS Parviflorae SECTION Parviflorae Lindley 1990.
Found in Brazil in Minas Gerais as a small sized, warm to cool growing lithophyte at 900m, this attractive species is one of the so-called rupicolus Laelias.

 

 

 

 

 

 


The close up photo of the flower shows why enthusiasts choose to grow this species.

 

 

 

 

 

 

 


Masdevallia veitchiana Rchb.f 1868 SUBGENUS Masdevallia SECTION Masdevallia SUBSECTION Coccineae Veitch 1889 is known as the king of Masdevallias.
A small sized, cold growing terrestrial or lithophyte (rarely epiphytic) species with erect leaves is found at 2,000-4,000m around Macchu Picchu in Peru. Its habitat is steep rocky slopes covered with grasses and shrubs in full sun where the leaves are protected by the grasses.
This concludes a brief summary of WOC22 in Ecuador. I am working on a 2-3 part Powerpoint showing some of the orchids and sights from South America.
