Slipper Orchid

An outbreeding morphotype of Cypripedium passerinum with separate anthers and stigma was discovered in the Beringian region of southwestern Yukon. The occurrence of this breeding system in Beringia is attributed to the persistent advantage of outbreeding over hundreds of thousands of years in this unglaciated area, whereas the widespread occurrence of exclusively self-pollinating races elsewhere in Canada is attributed to advantages in colonization of recently deglaciated territory which first became available less than 10,000 years ago, and/or to a changing and more forested habitat.

Abstract Cypripedium calceolus is considered an endangered species in the territory of Poland. Population of this rare species, situated at Lake Kwiecko (Western Pomerania), was regularly monitored in the years 1986-2013. The studied population has been under the permanent influence of the nearby hydroelectric power plant for almost 45 years. The field observations showed that the power plant had no negative impact on the condition of Cypripedium calceolus population. An indication of its good condition was, among others, an increase in the size - from 150 to 350 specimens within the study period.

Interference Hypothesis

It has been suggested that European Skipper butterflies (Thymelicus lineola) trapped in the lips of the Showy Lady’s-slipper orchid (Cypripedium reginae) may interfere with pollination. This could occur through blockage of the pollinator pathway, facilitation of pollinator escape without pollination, and/or disturbance of the normal pollinators. A large population of the orchid at an Ottawa Valley site provided an opportunity to test the interference hypothesis. The number of trapped skippers was compared in 475 post-blooming flowers with regard to capsule development and thus seed development. The presence of any skippers within flowers was associated with reduced capsule development (P = 0.0075), and the probability of capsule development was found to decrease with increasing numbers of skippers (P = 0.0271). The extent of a negative effect will depend on the abundance of the butterflies and the coincidence of flowering time and other factors. Counts of skippers trapped in flowers were found to follow closely a negative binomial distribution (P = 0.8656).

Mature Seeds

The histological and histochemical changes in developing seeds of Cypripedium debile Rchb. f., a native slipper orchid species with horticultural potential, were investigated. The effects of timing for seed collection, culture media, and cultural conditions were also examined. The optimum germination percentage occurred when mature seeds were collected and sowed on 1/4 Murashige and Skoog basal medium. Besides, the liquid culture promoted germination of mature seeds. This finding is contrary to most other Cypripedium species, which are relatively easy to germinate with immature seeds. Moreover, two notable cytological changes of C. debile were observed. First, the suspensor cell protruded beyond the micropyle opening of the inner seedcoat, making the inner seedcoat not substantial. Second, Nile red staining indicated that the deposition of cuticular material on the seedcoat was fragmentary. It is proposed that the less hydrophobic nature of the seedcoat makes mature seeds of C. debile easier to obtain water and nutrients for germination.

A micropropagation protocol for an endangered slipper orchid species, Cypripedium formosanum Hayata, through axillary buds from adult plants has been developed. The season of explant collection is crucial for the initial success of an aseptic culture. Explants collected in the middle of January gave the highest percentage of explant survival (54.2%) and shoot-forming percentage (41.7%). Of the two cytokinins tested, N6-benzyladenine (BA) was found to be superior to thidiazuron for normal shoot formation. The optimum result was obtained in quarter-strength Murashige and Skoog medium containing 22.2 or 44.4 μM BA in which the cultures produced 6.3 and 7.1 shoots per explant with 10.6 to 11.7 mm average length after 90 d of culture. Regenerated shoots rooted for 60 d in the basal medium with 1 g·L−1 activated charcoal and 20 g·L−1 potato homogenate were ready for growth in pots. This is the first report on shoot multiplication in vitro from mature plants of Cypripedium that provides a reliable method for propagating the selected elites.

Slipper Orchid

The first natural hybrid in the sectionIrapeanaof the orchid genusCypripediumis described and illustrated based on Guatemalan material. A molecular evaluation of the discovery is provided. Specimens with intermediate flowers betweenC. irapeanumandC. dickinsonianumwithin ITS andXdhsequences have the signal sequence of both these species. The analysis of plastid sequences indicated that the maternal line isC. irapeanum. Information about the ecology, embryology and conservation status of the novelty is given, together with a distribution map of its parental species,C. irapeanumandC. dickinsonianum. A discussion of the hybridization betweenCypripediumspecies is presented. The potential hybrid zones between the representatives ofCypripediumsectionIrapeanawhich were estimated based on the results of ecological niche modeling analysis are located in the Maya Highlands (C. dickinsonianumandC. irapeanum) and the eastern part of Southern Sierra Madre (C. molleandC. irapeanum). Moreover, all threeCypripediumspecies could inhabit Cordillera Neovolcánica according to the obtained models; however, it should be noticed that this region is well-distanced from the edges of the known geographical range ofC. molle.
