Abstract: The integration of fine-scale taxonomic results into a comprehensive phylogenetic classification remains an ongoing challenge in modern systematics, particularly for infraspecific variants and interspecific hybrids, which are often overlooked. To address the resulting nomenclatural gaps and instabilities, this study provides a significant update by introducing numerous nomenclatural novelties for selected vascular plant genera, with a special focus on nothotaxa. In total, this work validates 452 nomenclatural novelties across 31 families, including Aizoaceae, Amaranthaceae, Amaryllidaceae, Apiaceae, Apocynaceae, Asteraceae, Berberidaceae, Cactaceae, Cistaceae, Crassulaceae, Cupressaceae, Cyperaceae, Equisetaceae, Fabaceae, Gesneriaceae, Melanthiaceae, Orchidaceae, Poaceae, Ranunculaceae and Saxifragaceae, ect. Among them are the establishment of 12 new nothogenera: × Osteolaena [Amaranthaceae], × Chrysania, × Cicuca, × Ozodes and × Psepaurea [Asteraceae], × Turdenicarpus [Cactaceae], × Astoxytropis [Fabaceae], × Eucongia [Gesneriaceae], × Pseudillium [Melanthiaceae], × Batepalum [Orchidaceae], × Rankwithia [Ranunculaceae] and × Mitarella [Saxifragaceae]; 59 nothoranks [five nothosubgenera, 42 nothosections, six nothosubsections and six nothoseries] under seven nothogenera [× Anacamptorchis, × Dactylocamptis, × Dactylodenia, × Gymnanacamptis, × Orchidactylorhiza, × Orchigymnadenia and × Orchimantoglossum] for the first time and as additions to five natural genera [Cattleya, Dactylorhiza, Paphiopedilum, Phalaenopsis and Pulsatilla], respectively; moreover, 360 new nomenclatural acts are proposed, covering 139 new combinations, 209 new combinaton and status, six new status, and six new replacement names; besides, nine names are synonymized under eight taxa. These changes reconcile hybrid taxonomy with contemporary phylogenetic insights, stabilize nomenclature and provide a crucial reference to support accurate identification, biodiversity documentation, and conservation efforts.

Abstract: The intensification of agriculture and the ongoing degradation of soils in the highlands of western Cameroon are compromising the sustainability of vegetable production systems, particularly that of strawberries (Fragaria ananassa), a crop that is increasingly valued in the region. This study aims to evaluate the effect of different types of organic amendments (chicken manure and compost) and mineral amendments (NPK fertilizer) on the growth and health of strawberry plants. The experiment was conducted using a completely randomized block design with six treatments: a control (T0), two doses of chicken manure (20 t/ha, T1; 30 t/ha, T2), two doses of compost (10 t/ha, T3; 20 t/ha, T4) and a chemical treatment (NPK 14-24-14 at 100 kg/ha, T5), each repeated three times. The parameters studied included: vegetative growth (height, leaf area, stolons), incidence and severity of leaf diseases. Pathogens were identified using identification keys and microscopic observations of pure strains obtained on PDA medium. The results revealed that organic amendments significantly improved plant growth. Manure at 30 t/ha (T2) generated the best performance in terms of vegetative growth. However, high-dose treatments (T2, T4) and chemical fertilizer (T5) were associated with a higher incidence of fungal diseases, with Colletotrichum sp., Fusarium sp., and Mycosphaerella sp. identified as the main pathogens. Compost at 10 t/ha stands out as the most effective amendment, combining agronomic performance and disease resistance. The adoption of organic fertilizers could therefore be a significant asset in sustainably improving strawberry production in the highlands of western Cameroon.
