We present a method in which the optimal interpolation of multi-scale processes can be expanded into a succession of simpler interpolations. First, we prove how the optimal analysis of a superposition of two processes can be obtained by different mathematical formulations involving iterations and analysis focusing on a single process. From the different mathematical equivalent formulations, we then select the most efficient ones by analyzing the behavior of the different possibilities in a simple and well-controlled test case. The clear guidelines deduced from this experiment are then applied to a real situation in which we combine large-scale analysis of hourly Spinning Enhanced Visible and Infrared Imager (SEVIRI) satellite images using data interpolating empirical orthogonal functions (DINEOF) with a local optimal interpolation using a Gaussian covariance. It is shown that the optimal combination indeed provides the best reconstruction and can therefore be exploited to extract the maximum amount of useful information from the original data. © Author(s) 2014.

A wider concept of Justicia L. and Strobilanthes Blume (Acanthaceae) is now generally accepted as the characters used to distinguish related genera, namely an elastic placenta and greater ovule numbers, are not diagnostic and appear to be derived characters. In consequence the following new combinations are needed to bring the names of Indian species into line with currently accepted generic limits: J. apiculata (Bedd.) J. R. I. Wood "≡ Rungia apiculata Bedd.", J. himalayensis (C. B. Clarke) J. R. I. Wood "≡ Rungia himalayensis C. B. Clarke", J. latior (Nees) J. R. I. Wood subsp. latior "≡ Rungia longifolia subsp. latior (Nees) Cramer", which results in the new varietal combination of J. latior var. anamalayana (Chandrab. and V. Chandras.) J. R. I. Wood, J. latior subsp. longifolia (Nees) J. R. I. Wood "≡ Rungia longifolia Nees subsp. longifolia", J. mastersii (T. Anderson) J. R. I. Wood "≡ Rungia mastersii T. Anderson", J. wightiana (Nees) J. R. I. Wood "≡ Rungia wightiana Nees", Strobilanthes alternata (Burm. f.) E. Moylan ex J. R. I. Wood "≡ Hemigraphis alternata (Burm. f.) T. Anderson", Strobilanthes brunelloides (Lam.) J. R. I. Wood "≡ Hemigraphis brunelloides (Lam.) Bremek.", Strobilanthes cordifolia (Vahl) J. R. I. Wood "≡ Stenosiphonium cordifolium (Vahl) Alston", Strobilanthes crossandra (Steud) J. R. I. Wood "≡ Hemigraphis crossandra (Steud.) Bremek.", Strobilanthes pavala (Roxb.) J. R. I. Wood "≡ Hemigraphis latebrosa (Heyne ex Roth) Nees", Strobilanthes urens (Roth) J. R. I. Wood "≡ Hemigraphis urens (Roth) J. R. I. Wood", Strobilanthes venosa (Heyne ex C. B. Clarke) J. R. I. Wood "≡ Hemigraphis venosa Heyne ex C. B. Clarke", Strobilanthes wightii (Bremek.) J. R. I. Wood "≡ Stenosiphonium wightii Bremek.". The following new names are also provided for species where the epithet cannot be transferred as it is blocked by a pre-existing epithet in the genus: J. concinna J. R. I. Wood "≡ Rungia elegans Dalzell and Gibson", J. crenatifolia J. R. I. Wood "≡ Rungia crenata T. Anderson", J. eudoxa J. R. I. Wood "≡ Rungia laeta C. B. Clarke", J. heyneana J. R. I. Wood "≡ Rungia linifolia Nees", this new name resulting in the new varietal combination J. heyneana var. saldanhae (Mascar. and Janarth.) J. R. I. Wood, J. meghalayana J. R. I. Wood "≡ Rungia khasiana T. Anderson" and J. vallis-silentiosae J. R. I. Wood "≡ Rungia sisparensis T. Anderson ex C. B. Clarke", Strobilanthes carinei J. R. I. Wood "≡ Stenosiphomium setosum T. Anderson", and Strobilanthes sinuata J. R. I. Wood "≡ Hemigraphis repanda (L.) Hallier f.". Lectotypes are designated for the following basionyms: Haplanthodes neilgherryensis (Wight) R. B. Majumdar, Hemigraphis latebrosa var. rupestris C. B. Clarke, Hemigraphis platycarpos C. B. Clarke, Hemigraphis venosa Heyne ex C. B. Clarke, Ruellia alternata Burm. f., Ruellia confinis Nees, Ruellia confinis var. β, Ruellia diffusa Nees, Ruellia ebracteata Dalzell, Ruellia elegans Hook, Ruellia pavala Roxb., Ruellia repanda L., Ruellia urens Roth, Rungia apiculata Bedd., Rungia himalayensis C. B. Clarke, Rungia linifolia Nees, Rungia khasiana T. Anderson, Rungia sisparensis T. Anderson ex C. B. Clarke, Rungia wightiana Nees, Stenosiphonium confertum Nees, Stenosiphonium subsericeum Nees, Stenosiphonium wightii Bremek., and Strobilanthes burmanica Kurz. Neotypes are provided for Rungia elegans Dalzell and Ruellia latebrosa Heyne ex Roth. The opportunity is taken to recognize Haplanthus neilgherryensis Wight formally as variety neilgherryensis (Wight) J. R. I. Wood, with the variety transferred from Haplanthodes tentaculatus (L.) Nees.

Anostracan bioregions were identified for Australia. These regions were quantitatively defined using species distributions compared through Jaccard's Coefficient of Community Similarity, and qualitatively defined using regional soils data. Community assemblages are quantified using Fager's Index of Recurring Species Groups. Substrate geochemistry was used to investigate additional relationships, but was limited by the constraints of available data. However, the highly salinized soils directly relate to Australia bearing the highest diversity of halophilic anostracan taxa. Three anostracan biogeographical regions are defined for Australia: Western, Eastern and Southern. Copyright © 2014 Magnolia Press.

The worldwide genus Eulimnadia previously with only five species described from Australia, is known now to have at least 15 endemic species plus about 10 undescribed species detected by molecular means. Most have variable morphological features, though each has a distinctive resting egg morphology. Many occur in the known branchiopod hot spot of the Paroo/Bulloo catchments in western New South Wales and Queensland. Some are specific to gnammas (rock holes). Given the rarity of males, androdioecious reproduction is probable in most species. Keys are provided for all known Australian species. Copyright © 2016 Magnolia Press.
