INTRODUCTION In the period 1793-1813, William Roxburgh was Superintendent of the East India Company’s Botanic Garden in Calcutta (Robinson, 2008). Thanks to this appointment, Roxburgh occupied a pivotal position in the botanical exploration of Asia at that time, though it required Roxburgh’s industry, diplomacy and organisational skill to make best use of this opportunity. Plant specimens and material for propagation and planting arrived in Calcutta in large quantities sent by Roxburgh’s correspondents, friends, family members and Company agents from many locations as summarised in Roxburgh’s Hortus Bengalensis (Roxburgh, 1814). Roxburgh named and wrote descriptions of many of these species, and generally had his team of artists draw them. The bulk of this documentation remained unpublished during Roxburgh’s lifetime, but many species were described in the two posthumous editions of the Flora Indica (Roxburgh, 1820 – 1824; 1832). The Moluccas were an important source of new plants for Roxburgh and also of stock material of highly valued spice plants such as nutmeg and clove. Roxburgh’s nurseryman, Christopher Smith, was despatched to the Moluccas for the purposes of plant collecting at the end of 1795, having only arrived in Calcutta in April of that year (Robinson, 2008). Smith was to spend much of the next decade collecting in the Moluccas. Roxburgh included at least 150 plant species that he reported as originating from the Moluccas in his various publications. The identity of some of these taxa remains obscure. One such poorly known Moluccan species is Eranthemum diantherum Roxb. (Acanthaceae). Forman (1997) does not list the species, reflecting an absence of herbarium material among the main collections known to contain Roxburgh specimens. It is likely therefore that the only original material for Roxburgh’s name consists of the Roxburgh drawing number 1311. Consultation of herbarium material in the Kew Herbarium in comparison to images of the copy of the drawing in the Kew collection, made it clear that Roxburgh’s species was the same as Pseuderanthemum depauperatum Merr. Merrill described this species from material collected by C.B. Robinson in 1913 on the island of Ambon during his ill-fated expedition to recol- lect the species described by Rumphius in the Seventeenth Century. As Roxburgh’s name has priority by nearly a century over Merrill’s, I here make a new combination in Pseuderanthemum for Eranthemum diantherum Roxb. I also designate lectotypes for Roxburgh’s name and its new synonym. Pseuderanthemum diantherum (Roxb.) I.M.Turner, comb. nov. Basionym: Eranthemum diantherum Roxb., Fl. Ind. 1 (1820) 112.
