Overlooked synonyms of Philippine species of Croton (Euphorbiaceae)

In a footnote to his description of Tiglium officinale Klotzsch ( Croton tiglium L.) in Hayne’s ‘Getreue Darstellung und Beschreibung der in Arzneykunde gebräuchlichen Gewächse’ 14: sub t. 3 (1843), Johann Friedrich Klotzsch (1805—60) published brief Latin diagnoses of four other species known to him from specimens at Berlin collected on the island of Luzon in the Philippines by the English traveller Hugh Cuming (1791— 1865). Klotzsch’s names for these species have been overlooked by later writers, notably by Jean Mueller (1828—96) of Aargau, who in 1865 described the same species under different names from duplicate specimens at Geneva, and by the compilers of the Index Kewensis. Cuming’s numbered exsiccatae are to be found in many herbaria; hence the correlation of Klotzsch’s and Mueller’s names, although based on different types, presents no difficulty. Mueller kept Tiglium in Croton, as have most authors. Fortunately, although Klotzsch’s names have priority over Mueller’s, no changes take place in established nomenclature as Klotzsch’s epithets cumingii, subincanum, lanceolatum, and pubescens under Tiglium have already been used under Croton for other species. Vol. 14 of Hayne’s ‘Getreue Darstellung’ was never completed. According to Botanische Zeitung 5 (1847) 206, Heft 1, tt. 1—12, was published in 1843 and Heft 2, tt. 13—24, in 1846. Klotzsch published several new names in the text to plates 3, 12, 14, 15. Linnaea vol. 34 was published in 6 parts: Heft 1—4, pp. 1—512, in 1865, Heft 5—6, pp. 513—752, in 1866. Mueller’s paper occupies pp. 1—224.
