B7. Neocussonia halleana (Bernardi) Lowry, G.M. Plunkett, Gostel & Frodin View in CoL , comb. nov. ( Fig. 2D View Fig ).

÷ Schefflera halleana Bernardi View in CoL in Ber. Schweiz. Bot. Ges. 76: 371. 1966.

Lectotypus (designated here): MADAGASCAR. Prov. Antsiranana: Vallée de la Lokoho, Mont Beondroka au N de Maroambihy , 1000-1450 m, 17-22.II.1949, bud & fl., Humbert View in CoL 23495 ( P [ P00442780 ]!; isolecto-: G [ G00015605 , G00015606 ]!, P [ P00442779 ]!) .

Habitat and distribution. – Neocussonia halleana is known only from Marojejy National Park in northeastern Madagascar, where it is restricted to ericoid thicket and high altitude humid forest on and just below the summits of Marojejy and Beondroka ( MADAGASCAR CATALOGUE, 2017) between c. 1,700 and 2,100 m elevation.

Notes. – The label data accompanying Cours 4388 (G, P) indicate that it was collected on the summit of Marojejy on 28 March 1949, but give the altitude as 1000 m, which is far below the top of the mountain. Cours and Humbert both participated in the March 1949 expedition to Marojejy during which this material was gathered, and collections of many species clearly taken from the same individuals were distributed under both of their numbers. It may be that Cours 4388 is identical to Humbert 23495, and indeed this interpretation was used at G, where their sheet [G00015606] is recorded as an isotype. However, given the different collection date, we have chosen not to regard this collection as comprising type material.

There are two specimens of Humbert 23495 at P, one of which bears an annotation by Frodin made in 2001 indicating it as the lectotype, but this designation was never published. We have selected this specimen as the lectotype as it is the more complete of the two sheets .
