“…Therefore, before sowing process, breaking pollinaria into pollinia and even smaller pieces can increase the success of germination significantly. These results are parallel with other in vivo results regarding germination differences between inner and outer walls of tetrads (Swamy 1947;Poddubanya-Arnoldi 1976). Our comparison of pollinia and pollinaria germination supports those results.…”

In Turkey the tubers of about 120 orchid species are widely collected for manufacturing the traditional drink salep. In this study, we focused on the in vitro germination of the pollen of the salep orchid species Ophrys mammosa, Orchis provincialis, Anacamptis morio subsp. morio, Orchis simia and Neotinea tridentata and discussed the potential effects this might have on the conservation of these orchids by reducing the need to collect them in the field. Pollen was sown on different media; Knudson, Orchimax and the medium described by Malmgren, and then incubated at 24 ± 1 °C in darkness for 24 h. Germinated pollen was stained with Brilliant Blue and examined under a stereoscopic microscope. Results of Tukey and Dunnett T3 statistical tests indicated that in terms of percentage germination, the best germination was observed on O. mammosa by 55% and Orchimax was the most successful medium by 50.5%. For pollinaria germination, the best rate was observed on O. mammosa by 69%. The medium Malmgren was the best germinative by 61.3%. It is clearly seen that difference in germination rates among studied species are achieved using different media. The development of such a method of studied species in this research points to the fact that this is possible and should serve as encouragement for others to devise procedures for other species. These kinds of researches on propagation of orchids would be useful to reintroducing some of the rarer, endangered and endemic species in Turkey such previously succeed for Orchis militaris and Liparis loeselii in Great Britain.

“…The homology of the functional stamens present in orchids has been discussed by Brown (1833), Lindley (1853), Darwin (1862), Swamy (1948), and Rao (1974). Further investigation was not undertaken here; we assume that all monandrous orchids have A 1 , all diandrous orchids have a 1 and a 2 , and triandrous orchids have A 1 , a 1 , and a 2 .…”

“…Sclerotic seed coat-Significance has been attributed to the fact that both Apostasia and Vanilla (as well as Selenipedium, which was not a terminal in this analysis) have a hard, black ''sclerotic'' seed (Swamy, 1947). Garay (1986) interpreted this state as a symplesiomorphy.…”

“…Garay (1986) interpreted this state as a symplesiomorphy. Rübsamen (1986) and Nishimura and Tamura (1993) showed that in Apostasia it is the inner layer of the outer integument that becomes sclerotic, while in Vanilla it is the outer layer of outer integument (Swamy, 1947;Krupko, Israelstam, and Martinovic, 1954), indicating that the condition is not homologous in these taxa. (1948) and Lavarack (1971) discussed this character, indicating that cypripedioids and apostasioids have six vascular traces that enter the flower, while the monandrous orchids have three.…”

A cladistic analysis of Orchidaceae was undertaken for 98 genera using 71 morphological apomorphies based on a reconsideration of previous character analyses and newly discovered variation. The equally weighted analysis found 60 000 most parsimonious trees with low consistency (CI = 0.29) but high retention (RI = 0.83). The strict consensus reveals a significant amount of structure, and most traditionally recognized subfamilies are supported as monophyletic, including the Apostasioideae, Cypripedioideae, Spiranthoideae, and Epidendroideae. Orchidoideae in the broad sense are paraphyletic, giving rise to spiranthoids. Vanilloids are sister to epidendroids, although exhibiting several states otherwise found only in clearly basal groups, such as Apostasioideae. The nonvandoid epidendroids are poorly resolved, due to a high degree of homoplasy. The vandoids appear to be monophyletic, contrary to recent molecular evidence, possibly due to repeated parallel development of the vandoid character suite. The importance of vegetative characters as evidence putatively independent from floral features is demonstrated in the placement of Tropidia. Implied weighting analysis of these data resulted in similar patterns at high levels, although the Orchidoideae and Spiranthoideae may each be monophyletic and the nonvandoid epidendroids are more resolved. The high degree of structure implied in previous orchid classifications must be reconsidered, given the poor resolution at lower levels in the present trees.

“…These and other Vanilla species have been treated in various monographic works (Correll 1953;Hooker 1973) including the life history of V. planifolia (Swamy 1947). This belief is also reinforced by the fact that these orchids share many similar characteristic features making researchers (Dressler 1981) conclude that the genus was differentiated when the primitive continent of Gondwanaland divided 120 million years ago, based on the plate tectonics theory.…”

Vanilla is naturally distributed in Mexico and parts of Central America and the history of origin of cultivated vanilla suggests that the entire stock outside Mexico may be from a single genetic source. In the present study, RAPD polymorphism was used to estimate the level of genetic diversity and interrelationships among different collections of Vanilla planifolia Andr., and few related species, including both leafy and leafless types such as V. tahitensis J.W.Moore, V. andamanica, Rolfe, V. pilifera Holtt., and V. aphylla Blume. Studies revealed that there are very limited variation within collections of V. planifolia, indicative of its narrow genetic base, and of the related species we tested, V. tahitensis is nearest to V. planifolia. The species studied are diverse and have a similarity ranging from 1.2 to 57.3 %. Of the sampled taxa, V. andamanica is the most divergent and there is also reasonable variability within its collections, indicating the possibility of natural seed set. A total of 82 polymorphic bands expressed in the RAPD profiles were used to generate a genetic distance matrix, which was then used in cluster analysis. Specific groupings were revealed by the cluster analysis whereby the leafless forms (V. aphylla, V. pilifera and the new species) and V. andamanica formed separate clusters. This is the first report of species interrelationship studies, including both cultivated and wild vanilla species.
