Overview of Psychotria in Madagascar (Rubiaceae, Psychotrieae), and of Bremekamp's foundational study of this group. Candollea 75: 51–70. In English, English abstract. Psychotria L. (Rubiaceae, Psychotrieae) is a large pantropical genus that is one of the largest genera in Madagascar, with almost all of its species endemic to the island and an unusually wide range of morphological variation. Cornelis E.B. Bremekamp (1888–1984) presented a detailed taxonomic treatment for Madagascar and the Comores that classified 143 species in Psychotria and six segregate genera, and that has been influential in Rubiaceae systematics but also problematic. Molecular systematic studies have found Bremekamp's six genera nested within Psychotria, but did not study most of their unusual characters. Here his genera and their morphological features are studied in light of our current knowledge of Psychotria in Madagascar and overall understanding of this genus. Some unusual characters are detailed here for Malagasy Psychotria. A new name, Psychotria deflexiflora C.M. Taylor, is published as a legitimate name for Psychotria penduliflora Bremek.

Unraveling the taxonomic identity of Cocos nucifera f. palmyrensis (Arecaceae: Cocoseae). Candollea 75: 25–30. In English, English abstract. The main traits of the rich equatorial vegetation covering the remote coral atoll Palmyra in North Pacific Ocean, where groves of Cocos nucifera L. (Arecaceae) currently dominate on other formations, are here summoned. Way and timing of human activities in historical and more recent times, which possibly altered the original vegetation, are also briefly reviewed. The unusually large size of Palmyra coconut fruits had astonished the American botanist Joseph Francis Rock (1884–1962) who sent four fruits to the renowned Florentine palm specialist Odoardo Beccari (1843–1920). Beccari described the material and validly published it in 1916 as Cocos nucifera f. palmyrensis Becc. Part of the original material was retrieved at FI. One of the two coconut fruits still kept at FI is here designated as lectotype of the Beccari name, which is here elevated to the rank of variety, reflecting better than form current concepts for isolated island populations. Palmyra Atoll with its coconuts played a part in the age-old dispute on the geographical origin of Cocos nucifera. This taxon was cited by Beccari and by Emilio Chiovenda (1871–1941) as a support to their hypotheses of an Asian origin of the species. The significance of these dated interpretations in the light of currently available information is here briefly discussed.

Botanical collections and an early printed vegetation profile. Candollea 75: 31–43. In English, English abstract. In 1841–1843 Theodor Kotschy travelled extensively in Iran and collected vast amounts of plant specimens. Edmond Boissier undertook the determinations of the material and validated numerous names new to science, often exclusively based on Kotschy's specimens. Subsequently Rudolf Friedrich Hohenacker arranged for the distribution of this material in two exsiccata series, which are today available for consultation in numerous herbaria. Kotschy's unknown botanical field book kept in the archive of the Herbarium Haussknecht in Jena is analysed for the first time and so is an exceedingly rare, printed vegetation profile published by Hohenacker in 1846, which summarizes Kotschy's pertinent sketches done in the field in southwestern Iran in 1842. Both documents are set into the context of their time and are shown to echo earlier works by Alexander von Humboldt done in tropical America. In addition, extensive information on Kotschy's travels in Iran is presented from Ludwig Ritter von Köchel's report as well as from archival material kept in the Herbarium Haussknecht and the Naturhistorisches Museum in Vienna.
