03CE2B10FF8FB83FFF7DF9AAFBA0A388.taxon	description	Phyllanthera nymanii was previously documented by only six specimens, obtained from montane forests in Central and Morobe Provinces (Forster 1990). The latest gathering establishes a new distributional endpoint near the Indonesian border. The Ambunti population is a lowland morphotype with short dichasia (2 – 6 cm long) and adaxially hairy petals. It may be deserving of future recognition as a distinct variety.

The Waskuk specimens (Figs. 7 – 10) are the only correlated collections (i. e., flowers and fruits clearly of conspecific origin) from the " bellum complex " of species with exceptionally large seeds (sensu Verdcourt 1979). Taxonomic interpretation of the complex has been complicated by past inability to connect the flowering and fruiting structures of its component taxa. Owing to the uncertainties arising from uncorrelated material, Verdcourt (1979) and Nielsen et al. (1985) expressed doubts about the reliability of circumscriptions within this group. With the complete sets now in hand, Archidendron calliandrum keys out cleanly from A. bellum Harms (1917: 40) and A. rufescens Verdcourt (1977: 230) suggesting that at least with these three species, the separations are viable. Archidendron calliandrum was previously known only from the Strickland-Fly River and the Vogelkop (Nielsen et al. 1985). The Waskuk occurrence extends the range into northern PNG.	en	Takeuchi, Wayne (2012): Modern sequels to the Kaiserin-Augusta-Fluss itinerary of Carl Ledermann: floristic discoveries from the upper Sepik of Papua New Guinea.

03CE2B10FF83B83CFF7DFA44FB83A35E.taxon	description	The Waskuk collection belongs to an alliance comprised of Archidendron arborescens (Kostermans 1966: 365) Nielsen in Nielsen et al. (1985: 80), A. kalkmanii, and A. novoguineense (Merrill & Perry 1942: 394) Nielsen in Nielsen et al. (1985: 84). Based on its description, A. kalkmanii is the species at Waskuk, although the corolla (to 20 mm long) is above the reported size range for that species (12 – 14 mm). Except for flower size, Archidendron arborescens and A. kalkmanii are so similar that they are more like varieties, or at most, like geographic subspecies — with A. kalkmanii occurring on the north side of the Central Divide and A. arborescens on the south. There are no qualitative discontinuities in their character profiles. All the differences tabulated in Nielsen et al. (1985: 83) are quantitative. As shown by the Waskuk collection, quantitative variation is likely to be understated and thus misleading, when taxa are characterised from small numbers of specimens. Archidendron kalkmanii is historically known only from the Jayapura area of western New Guinea (Indonesian Papua). Its previously unknown fruits (seen on Takeuchi et al. 17577) are identical to those for A. arborescens. If accepted as a good taxon, A. kalkmanii is now recorded for PNG.	en	Takeuchi, Wayne (2012): Modern sequels to the Kaiserin-Augusta-Fluss itinerary of Carl Ledermann: floristic discoveries from the upper Sepik of Papua New Guinea.

03CE2B10FF80B83BFF7DFE41FE34A494.taxon	description	Inocarpus ademanus is easily identified by the dense, rust-colored hairs covering the exocarp. Fruiting pedicels are 3 – 8 × 2 – 3 mm (not subsessile). Unlike its allies, the style base in I. ademanus is obviously lateral and inserted at right angles to the main axis. The fruit is flat — not merely compressed as in other species. Leaves are at the small end of the generic size range (largest blades only 10.3 × 5.2 cm) and unusually blackspotted on abaxial surfaces. Taken collectively, the character states in this new species are the most distinctive in the genus.	en	Takeuchi, Wayne (2012): Modern sequels to the Kaiserin-Augusta-Fluss itinerary of Carl Ledermann: floristic discoveries from the upper Sepik of Papua New Guinea.

03CE2B10FF80B83BFF7DFE41FE34A494.taxon	description	The distinction between Cryptocarya resinosa and C. weinlandii Schumann (1905: 270) is arguable. Kostermans (1968) accepted both species, but without specifically comparing them. Only one distinguishing character for C. resinosa (viz. the white-spotted exudate on leaves and fruits) was mentioned in its description and protologue. Specimens cited as C. weinlandii (in Kostermans 1968: 340) can also have these spots (e. g., NGF 10243, 10306). Cryptocarya weinlandii s. str. is found mostly in northeast New Guinea and the Solomons, while C. resinosa is historically known only from western (Indonesian) New Guinea. The Waskuk population provides a geographic link between the documented localities for C. resinosa and the westernmost station for C. weinlandii in PNG (previously Madang Province). If C. resinosa is accepted as a separate species, the Waskuk specimen is a country record for PNG. But given its pronounced similarity to C. weinlandii, it is unlikely that C. resinosa can survive future revision.
