Using the “Seidenfaden collection” in Copenhagen as an example, we address the common view that botanical garden collections of orchids are important for conservation. Seidenfaden collected live orchids all over Thailand from 1957 to 1983 and created a traditional collection for taxonomic research, characterized by high taxonomic diversity and low intraspecific variation. Following an extended period of partial neglect, we managed to set up a five-year project aimed at expanding the collection with a continued focus on taxonomic diversity, but widening the geographic scope to tropical Asia. -

At how- by any plant family present, accurate estimate of the of Malesian orchid is difficult to make. ever, an number species Subtracting the numberofestablishedsynonyms from the numberof names attributed to Malesian orchid species results in the staggering figure of 6414 species, with a retention of 0.74. This is ratio (ratio of ‘accepted’ species to heterotypic names) undoubtedly a overestimate, of the 209 Malesian orchid have been revised gross as most genera never their entire from availablerevisions estimate realis- over range. Extrapolating to a more tic retention ratio is problematic due to the small number of modern revisions and the different of treated. If look for Malesian of nature the groups we comparison at species wide ofretention ratios: some recently revised groups, we encounter a range Bulbophylluw sect.

Correspondingly, we find a wide rangeof estimates for the ‘real’ numberof known Male- sian orchid species: from 2050 to 5125. Another approach would be to look at a single area, and to compute the retention ratio for the orchid flora of that area.

Phalaenopsis
Chapter 23 Phalaenopsis Chia-Chi Hsu, Hong-Hwa Chen, and Wen-Huei Chen Abstract Phalaenopsis is one of the most popular cultivated orchids worldwide. So far, 92 native species and 34,112 hybrids of Phalaenopsis have been registered in the Royal Horticultural Society (RHS), but only 18 native species are frequently used for breeding. In Phalaenopsis market, large flowers with various colors are most popular. Phal. amabilis and Phal. aphrodite are the major species used for breeding the white-and-large-flower hybrids. The colored hybrids include pink, red- to- purple, green, yellow-to-orange, and black colors, as well as distinct colors in tepals with red lip. For large-and-red flowers,Phal. schilleriana and Phal. sanderiana are the major parent species, whereas Phal. equestris and Phal. pulcherrima are important for the development of the small- and medium-sized red flowers. Members of the subgenusPolychilos are the most important ancestors for yellow-to-orange flowers. More recently, there is an increased interest in plants with white, pink, or yellow colors with red stripes and/or spots. These traits are introduced from Phal. lindenii, Phal. stuartiana, and Phal. amboinensis. Furthermore, harlequin flowers which have clown-like spots and very complicated color patterns are released in the market, as well as hybrids with peloric and Bigfoot flowers. Besides color, scent and (a)biotic stress resistance are becoming important targets in Phalaenopsis breeding. Keywords Bigfoot · Breeding · Harlequin · Orchids · Peloric · Phalaenopsis C.-C.

Orchitheek 1 Uitgave: Nederlandse Orchideeën Vereniging
Nederlandse Orchideeën Vereniging – Orchitheek 1 Uitgave: Nederlandse Orchideeën Vereniging. Auteursrechten voorbehouden Phalaenopsis hieroglyphica Rchb.f. Sectie Zebrinae Syn. Phalaenopsis lueddemanniana ssp. Hieroglyphica Deze plant werd gevonden door P. Micholitz in het jaar 1890 op de zuidelijke eilanden van de Filippijnen in het Sulu-gebied, en werd overgebracht naar de Fa. Low en Co in Engeland. Ze werd door F. Reichenbach beschreven en gepubliceerd in de Gardeners’ Chronicle als Ph.lueddemanniana ssp. hieroglyphica. Deze naam is waarschijnlijk ontleend aan de kleur en tekening van de bloem. Verspreiding Het verspreidingsgebied is de groep zuidelijke eilanden in de Sulu-archipel (Filippijnen), waar de planten op bomen groeien die langs riviertjes staan in het laagland op een hoogte van 500 m. Beschrijving De planten groeien in een horizontale, lichtelijk omhoog gerichte stand tegen de bomen, of in humusnesten in de vorken van takken in de bomen. Zij hebben geen schijnknollen of bulben; de bladeren ontspruiten uit het hart van de wortelstok dicht opeen, zijn langwerpig, puntig aan het uiteinde, met een nerf in het midden. De kleur is effen grasgroen; bladeren stevig, niet vlezig en dik. De planten vormen niet meer dan 1 nieuw blad per groeiseizoen; het zijn uitgesproken trage groeiers. De wortels zijn zilverachtig en rond, vertakken zich en zijn 5 mm in dwarsdoorsnede. De bloemtakken ontwikkelen zich aan de onderkant van de wortelstok en tussen de onderste, oudste bladeren. Ze worden ongeveer 30 cm lang en jaar na jaar worden op dezelfde bloemtak bloemen geproduceerd. Naarmate de plant ouder wordt, neemt het aantal bloemen toe. Zoals exemplaren van andere ondersoorten van Ph.lueddemanniana wel doen, produceren zij geen jonge planten aan de bloemtakken. -
