Germination in the Cypripedium/Paphiopedilum Alliance
Germination in the Cypripedium/Paphiopedilum Alliance The colourful temperate ladyslippers including Cypripedium acaule, calceolus and reginae have attracted the attention of many investigators attempting to solve the problem of germinating the recalcitrant seeds (Arditti, 1967; Arditti et al, 1982; Curtis, 1942; Oliva and Arditti, 1984; Stoutamire, 1974, 1983; Withner, 1953). Germination of Cyp. reginae seed has perhaps attracted the most attention given that this species is particularly showy. Harvais (1973, 1974, 1980, and 1982) was the first Canadian investigator to approach the problem of axenic culture. He succeeded not only in germinating the seeds of Cyp. reginae but also in producing leafy seedlings. His death in 1982 cut short a promising research program and was a great loss. Frosch (1986) outlined a procedure to asymbiotically germinate and grow Cyp. reginae to flower in three years. More recently, Ballard (1987), has presented detailed results of his experiments in the sterile propagation of the same species, using seeds taken at early stages of development and at maturity. Of particular interest was his discovery that dormancy in Cyp. reginae seeds can be broken by refrigeration of the seeds at 5/C for two to three months prior to incubation at room temperature. He has achieved from 19–98% germination after three to four months using Knudson's “C” medium (Knudson, 1946) with seed taken 42 to 60 days after pollination. Cypripedium calceolus is a particularly attractive species, native to both North America and Europe. Carlson (1940) examined the formation of the seed of Cyp. parviflorum to gain a better understanding of the problems involved in germination. -
One New Endemic Plant Species on Average Per Month in New Caledonia, Including Eight More New Species from Île Art (Belep Islan
CSIRO PUBLISHING Australian Systematic Botany, 2018, 31, 448–480 https://doi.org/10.1071/SB18016 One new endemic plant species on average per month in New Caledonia, including eight more new species from Île Art (Belep Islands), a major micro-hotspot in need of protection Gildas Gâteblé A,G, Laure Barrabé B, Gordon McPherson C, Jérôme Munzinger D, Neil Snow E and Ulf Swenson F AInstitut Agronomique Néo-Calédonien, Equipe ARBOREAL, BP 711, 98810 Mont-Dore, New Caledonia.

The New Caledonian biodiversity hotspot contains many micro-hotspots that exhibit high plant micro- endemism, and that are facing different types and intensities of threats. The Belep archipelago, and especially Île Art, with 24 and 21 respective narrowly endemic species (1 Extinct,21Critically Endangered and 2 Endangered), should be considered as the most sensitive micro-hotspot of plant diversity in New Caledonia because of the high anthropogenic threat of fire. Nano-hotspots could also be defined for the low forest remnants of the southern and northern plateaus of Île Art. With an average rate of more than one new species described for New Caledonia each month since January 2000 and five new endemics for the Belep archipelago since 2009, the state of knowledge of the flora is steadily improving. -

Orchid of the Month for June, 2015 Oncidium Longipes by Bruce Adams
Orchid of the Month for June, 2015 Oncidium Longipes by Bruce Adams Figure 1: Oncidium longipes When I first fell in love with orchids, about forty years ago, Oncidium was my favorite genus. I loved the intricate flowers on long sprays, often with a wonderful fragrance. At that time, I worked as a volunteer in the orchid house at Planting Fields Arboretum. After repotting plants, I had the opportunity to take home back bulbs, and received pieces of Oncidium sphacelatum, O. flexuosum, and others that I can no longer remember. Every year they had an orchid auction, and for the extravagant price of five dollars, I purchased a multi-lead plant of O. ornithorhyncum. I became familiar with many of the various species, and at the time was a bit of an Oncidium expert. Forty years later, I’ve forgotten much, and with the recent changes in nomenclature maybe I wasn’t ever really an Oncidium expert, but rather a Trichocentrum, Gomesa, and Tolumnia expert! What hasn’t changed is my fondness for this vast genus (or group of genera). Plants can get quite large, such as Oncidium sphacelatum, which can easily can fill a twelve-inch pot, sending out three foot spikes with hundreds of flowers. But there are also miniatures like Oncidium harrisonianum, which can be contained in a three or four inch pot and sports short sprays of pretty little yellow flowers with brown spots. In fact, most Oncidium flowers are a variation of yellow and brown, although Oncidium ornithorhyncum produces pretty purple pink flowers, while Oncidium phalaenopsis and its relatives have beautiful white to red flowers, often spotted with pink. -

A total of 281 individuals were used to construct regional descriptions of D. kingianum and 139 individuals were measured for 19 morphological characters, and similarities and differences among specimens summarised using multivariate statistical methods. Patterns of morphological variation within D. kingianum are consistent with a single variable species that expresses clinal variation, with short-growing plants in the south and taller plants in the northern part of the distribution. The nrITS gene tree suggests two subgroups within D. kingianum subsp. kingianum, one comprising northern, the other southern individuals, which may overlap in the vicinity of Dorrigo, New South Wales.

What is phenology? • Phenology is the study of life history stages, such as leafing, flowering and berry ripening in plants, or migration and breeding in animals. Bees rely on nectar being available at the right • Changes in climate can alter the timing of time and plants rely on the pollinators too phenological events which may cause mismatch between the life stages of different species, for example: • Earlier or later flowering may change the amount of flowers available to pollinators • Changes in the fruiting period may result in reduced food availability for birds • Repeated recording of these crucial stages enables us to identify changes in phenology. Coat colour change in mountain hares is another example of phenology Courtesy of Tim Sparks www.naturescalendar.org.uk Which plants? Field and laboratory experiments have shown changes in the phenology of many moorland species.
