I am still trying to determine the name of this species. I posted some photos about a year ago and it was suggested it might be Diplocaulobium chrysotropis but Peter O'Byrne discounted this because "that species lacks distinct sidelobes". I was told when I bought it that it was from PNG. Any other ideas?

Tufted Duck
Pochard
Appearance: Rich rusty brown overall with contrasting white triangular patch under tail; male has pale eye. Also note peaked crown and rather long gray bill. In flight, both sexes show bold white wing stripe. Compare with female Tufted Duck (can have similar white patch under tail). Inhabits lakes and marshes, usually with surrounding reeds. Rather shy and often stays hidden in reeds, but at other times out in open water with flocks of Tufted Duck and Common Pochard.
Shape resembles both diving and dabbling ducks. Characteristic head profile with long bill, long sloping forehead and rather high rear crown (not unlike Pochard). White undertail usually visible also when on the water. Broad, white wing-bars and white underwing conspicous in flight. White undertail separated from white belly by brown band. Male with shining white eyes. Female with brown eye and less bright rufous tones to plumage. Immature similar to female, but with even less rufous. Immatures told from immature Pochard by by darker back, no facial markings and white (not grey) wing-bars. Note that Tufted Duck sometimes have white (but more diffuse) undertail. Beware also of hybrids with Pochard (note bill-pattern).
Sound:
Female call similar to female Tufted Duck's "kerr kerr", but thinner and with a strong, peculiar bi-tone. Male display call mostly consists of various short "chk" sounds.

Status: Scarce summer visitor and widespread winter migrant - most occur between October & February.
Conservation Concern: Amber-listed due to its small breeding population, as well as its localised wintering (< ten sites). The European population has been evaluated as Declining due to a moderate ongoing decline.
Identification: Medium sized, males with chestnut head and neck, black breast, grey flanks and black rump. Females duller grey-brown, with chestnut/pale brown breast, pale loral patch, eye ring and line behinde the eye.
Similar Species: Other ducks.
Call: Mostly silent. Males have characteristic wheezing cut off by a nasal short 'aaaooochaa(e)'.
Diet: Diving ducks - Diet consists largely of plant material. Inland, they feed predominantly on the spores and occasionally on the vegetative parts of aquatic plants.
Breeding: Nests on the ground among waterside vegetation.
Wintering: Show a preference for large shallow eutrophic waters, particularly those with well-vegetated marshes and swamps and slow flowing rivers.
Where to see: Loughs Neagh & Beg in County Antrim and Lough Corrib in County Galway support almost 25,000 birds and 12,000 birds respectively. Lough Derravaragh in County Westmeath, Lough Ennell in County Westmeath and Lough Kinale & Derragh Lough in County Longford are other important wintering sites (1,000- 3,000 birds).
Physical characteristics
The pochard is a stocky diving duck, smaller than a mallard. The male is pale grey with a rusty red head and neck, and a black breast and tail. The female is brown with a dark head and blotchy cheeks. In flight, birds show a pale grey wing-stripe.
Habitat
Vegetated swamps, marshes, lakes and slow flowing rivers with areas of open water. In winter, opten on larger lakes, brackish coastal lagoons and tidal estuaries.
Other details
This duck inhabits a major part of temperate Eurasia, from the British Isles to Mongolia. During the last decades it has extended its distribution westwards and south-westwards. It is now breeding regularly in small numbers in the Netherlands, Belgium, France and Spain. The birds of the European Union winter partly from Denmark to the British Isles and Bretagne; partly in Central Europe and the Mediterranean. Its is unlikely however that these birds have a different origin. Only for practical reasons they are considered as belonging to distinct populations. The birds wintering in north-western Europe are amounting to 350000 individuals; those of the Black Sea, the Mediterranean and Central Europe are estimated at 1000000 individuals (Scott & Rose). A few thousands of individuals of this last population reach sub-Saharan Africa. After an increase in numbers and an extension in distribution, the West European population seems currently to be somewhat declining. The trends of the East European populations, visiting e. g. Greece, are less well known but seem also to indicate some decline. In the western Mediterranean this decline is estimated at 70% during the last 20 years
Feeding
Green part of aquatic plants and grass , leaves, stems, roots and seeds. Occasionally aquatic invertebrates and insects amphibians and small fish. Feeds by diving, upending head-dipping and dabbling also filters mud on shore.
Breeding
Egg-laying begins mainly May, in all areas. Nest is build on ground close to water (usually within 10 m), in thick cover, or in water, built up above surface, in dense reeds and rushes. Nest is build on a platform, with shallow cup of reed stems, leaves, and other vegetation. Clutch size is 8-10, but ranging from 4-22 over 15 probably always 2 females sharing nest. Incubation lasts 24-28 days and the young fledge after 50-55 days.
Migration
Partially migratory; present throughout year in temperate regions (e.g. Central and NW Europe) but northernmost populations winter in Mediterranean basins, sub-Saharan Africa, Middle East, SW USSR, Indian Subcontinent, SE Asia and Japan. Vagrant to Faeroes, Azores, Canary and Cape Verde Is; also to Philippines, Guam and Hawaii
A species that has taxonomically been moved around a bit. Widespread across Asia from China, Assam, Cambodia, Laos, Myanmar, Thailand, Vietnam, Borneo, Peninsular Malaysia and Sumatra
This fish species of the genus Guyanancistrus, discovered in 2005, is new to science. It is believed to be all over eastern plateaus of Suriname, on the northern coast of South America, but has been found nowhere else. The ecologists who found it were surprised by the unusually large size of its mouth.

Ochraceous Bulbul
The ochraceous bulbul (Alophoixus ochraceus) is a species of songbird in the bulbul family, Pycnonotidae. It is found from Southeast Asia to Sumatra and Borneo. It is usually found in the mid-storey of broad-leaved evergreen and rainforests up to 1500 metres elevation.
The ochraceous bulbul was originally described in the genus Criniger until moved to the genus Alophoixus in 2009. Alternate names for the ochraceous bulbul include the brown white-throated bulbul and ochraceous bearded-bulbul.

Stunning yellow flowered species from eastern and southern Brazil. A specimen plant is a real sight.
Iris unguicularis 'Winter Iris'
(Click image to enlarge) Best known old fashioned species growing to around 30 cm tall (12"). Dappled light seems suit them best but they grow well in the sun if you keep the water up to them and good drainage, specially while they are estbalishing themselves. They have evergreen, strappy foliage and like to be left undisturbed up to 20 years.They flower from June to August with lovely perfume. Flowers are soft lavender blue with a white area around the rich egg-yolk signals. www.carrollscountrygardensnursery.net
This is the bloom on my species rose bush. The neighbor who gave it to me said the rose had been in the neighborhood for more than 100 years. I've since passed offshoots off to other neighbors. It does only bloom once, and I missed it last year because we were out of town, so I'm happy to catch it this year.
A species from Bolivia, Ecuador and Peru. It was commonly known as Oncidium trilobum but Kew has recognised that this species is synonymous with the species originally described as Oncidium aurarium.
B is Paramecium Caudatum, which was my favorite protozoan. I kept a culture of them all summer after 9th grade.

The Preble's meadow jumping mouse is a subspecies of jumping mouse found only in the uplands of Wyoming and Colorado. In 1998 this subspecies was listed under the Endangered species act as threatened throughout its range. Just last year (2008) it was delisted in Wyoming, in part due to the work of WYNDD. It was found that populations in WY are more widespread than previously known and threats to the species less severe than those at the time of listing.
This species was only described on 18 January 2011 in the Malesian Orchid Journal. It is not yet known where this species occurs in the wild.
The name refers to the seven nerves on the dorsal sepal. This species is similar to another recently described species, Dendrochilum tortile.
Gorse is a seasonally pretty for a few short weeks as it blooms. The balance of the year it is unattractive, bristling with long, sharp thorns and is a very dangerous fire hazard. It was brought to Bandon in Coos County, Oregon, by a Scotsman who missed it seasonal beauty. But it quickly spread growing thick and tall (6 feet and more) and crowding out native species. Despite efforts to control it gorse has spread south into Curry County, Oregon and north towards Coos Bay.
