Twenty-four new species of Memecylon (Melastomataceae) from Madagascar

“…– This new species closely resembles Memecylon mocquerysii , named after Albert Mocquerys who was a commercial collector of natural history specimens ( Candolle , 1901; Dorr , 1997; Dorr et al, 2017). Specimen labels in G indicate that the collections Mocquerys 409 and 410 , representing the original material of M. mocquerysii , were collected from Nosy Mangabe while Mocquerys 316 , cited here as a paratype of M. pseudomocquerysii , is from «Maroa» (one of 20 provinces of the 19th-century Merina kingdom and centered on what is now known as the Masoala Peninsula; fide Lloyd , 1850). Memecylon mocquerysii was later treated by Jacques-Félix (1985a) as conspecific with the Tanzanian M. cogniauxii Gilg, but subsequent molecular and morphological comparisons have shown it is distinct and should be recognized as a localized endemic of Nosy Mangabe and the western edge of the Masoala Peninsula ( Stone , 2014; R.D.…”

Taxonomy of nesomyine rodents (Muroidea: Nesomyidae: Nesomyinae): Designation of lectotypes and restriction of type localities for species-group taxa in the genusNesomysPeters

“…Some early explorers, missionaries, and naturalists left meticulous records of hours and distances traveled overland in Madagascar along the then rudimentary trail system, typically following alongside waterways (Lloyd 1851, Pearse & Aitken 1875, Oliver 1886, Rand 1936. Distances of 30-40 km (18-25 mi) per day were commonly achieved on the trail, allowing for wide variation according to weather, trail condition, and topography.…”
