This paper provides a taxonomic revision of Melanoxerus Kainul. & Bremer (Rubiaceae) – a genus of deciduous trees with eye-catching flowers and fruits that is endemic to Madagascar. Descriptions of three new species, Melanoxerus antsirananensis Kainul., Melanoxerus atropurpureus Kainul., and Melanoxerus maritimus Kainul. are presented along with distribution maps and a species identification key. The species distributions generally reflect the ecoregions of Madagascar, with Melanoxerus antsirananensis being found in the dry deciduous forests of the north; Melanoxerus atropurpureus in the inland dry deciduous forests of the west; Melanoxerus maritimus in dry deciduous forest on coastal sands; and Melanoxerus suavissimus (Homolle ex Cavaco) Kainul. & B.

The new species Phelipanche chionistrae Rätzel, Hand, Christodoulou & Uhlich (Orobanchaceae) is described from Chionistra, the highest summit of the Troodos range in Cyprus. Morphological data strongly suggest affinities to the Phelipanche rosmarina complex, predominantly West Mediterranean taxa, and Phelipanche olbiensis (Coss.) Carlón et al. The new taxon can be distinguished by a combination of characters such as general colouration, structure of calyx and type of indumentum. Also, it has a different ecology being restricted to a high-montane serpentinophytic coenosis. Currently, only a few populations of the taxon, which is a parasite mainly on the Cypriot endemic Alyssum troodi Boiss. (and possibly other serpentinophilous species), are known. According to the IUCN Red List Categories and Criteria it should be assessed as “Near Threatened”.

The liverwort and hornwort flora of Ecuador is still very incompletely known. We report three species new to Ecuador (Lejeunea rionegrensis Steph., Notothylas javanica (Sande Lac.) Gottsche, Riccia vitalii Jov.-Ast) and 38 new to the province of Morona Santiago based on our fieldwork in the surroundings of Gualaquiza, Morona Santiago, in 2019. The bryophyte flora of this area was explored in the early 20th century by the Italian missionary and naturalist Michel Allioni. A brief eulogy of the life and work of Michel Allioni is presented together with a revision of the species described by Stephani based on Allioni's Ecuadorian collections. Almost all of them are synonyms.

A new lectotype is proposed for this name that conforms to the protologue. Three further new species are described: Campanula monteverdensis Gardère from São Vicente, Campanula fransinea Gardère and Campanula cochleromena from São Nicolau, and Campanula vicinituba Gardère from Santo Antão. Campanula hortelensis Gardère, also from Santo Antão is placed in synonym of Campanula feijoana Gardère.

On the proper type designation for Camelina microcarpa, a wild relative and possible progenitor of the crop species C. sativa (Brassicaceae). In English, English abstract. Candollea 76: 55–63. The proper type designation of the name Camelina microcarpa Andrz. ex DC. (Brassicaceae) is discussed. This taxon is currently considered to be a wild relative and possible progenitor of the oilseed crop Camelina sativa (L.) Crantz, and thus the proper typification of the name C. microcarpa is important for further germplasm research and improvement of the crop species. At present, several (at least four) specimens deposited in herbaria G-DC, KW, and LE, are listed in literature and/or annotated in herbaria or online databases as the type (holotype or lectotype) of C. microcarpa. The original material deposited in G-DC [G00203789] is accepted here as the holotype of C. microcarpa because it appears to be the only original element used by Candolle when preparing his description of the new taxon. Isotypes from the Besser herbarium at the National Herbarium of Ukraine in Kyiv (KW-BESS) are discussed and illustrated. It is concluded that the holotype from G-DC and two well-preserved isotypes from KW-BESS [KW001003103, KW001003104] are sufficient for precise morphology-based application of the name C. microcarpa. Our analysis provided evidence that original material was collected by Andrzejowski no later than 1818 in the Podolian Governorate of the former Russian Empire, most probably in the eastern part of Moldova or adjacent southwestern parts of Ukraine, along the Dnister (Nistru, Dniester) River between the present-day town of Camenca (Kamenka) and the confluence of the Dnister and Yagorlyk (Iagorlîc) rivers, probably on limestone outcrops. It means that the type of C. microcarpa may belong to the southern Ukrainian populations, which are genetically different from northern and central Ukrainian ones; however, further field and molecular studies are needed because more than one genotype may in fact occur in that area.

The identity of the long-overlooked Ronabea morindoides and Patabea tenuiflora, synonymous with a species of Appunia (Rubiaceae). Candollea 76: 83–92. In English, English abstract. The identity of Ronabea morindoides A. Rich. has long been unclear and is here investigated. Two sheets of original material corresponding to this name are deposited in the General Herbarium of the National Museum of Natural History of Paris (P), and represent a mixed collection; one part of this material corresponds better with the description of this taxon and is more unambiguously identifiable, and is here designated the lectotype. With this typification, Ronabea morindoides represents a species of Appunia Hook. f. The identity of Patabea tenuiflora DC. has also remained uncertain since its description and is here clarified by studying the holotype in the Candolle Herbarium (G-DC); this is an additional synonym of R. morindoides. Taxonomic review of this group in the Guianas also finds that Ronabea morindoides is an older name for Appunia brachycalyx (Bremek.) Steyerm. and Appunia surinamensis Bremek. (Morindeae).
