Gaertnera luteocarpa Jongkind subsp. luteocarpa View in CoL

( Figs 1 View Fig , 4 View Fig )

Diagnostic characters

Fertile branches twice the size of the other subspecies (4 mm wide in dry state). Stipular tube densely pale hairy.

Distribution

Undergrowth of evergreen lowland forest often on swampy places. South-west Ghana and south Ivory Coast.

Additional specimens studied

GHANA. Western Region, Ankasa River Forest Reserve, fr., 4 Jan. 1969, Enti & Hall GC 39103 (GC n.v., K); ibid., young fr., 29 Dec. 1966, Hall & Enti GC 36155 (K); ibid., young fr., 12 Nov. 1967, Hall GC 37121 (K); Ankasa River Reserve, 24 Apr. 2001, Hawthorne & Gyakari 201a223 (FHO); ibid., 3 Mar. 2003, Hawthorne & Gyakari 203a123 (FHO); ibid., 28 Feb. 2005, Hawthorne & Gyakari 205a063 (FHO); near Ankasa Game Reserve, fr., 28 Feb. 1995, Jongkind, Abbiw & Markwei 2077 (MO, WAG)

Conservation status

The EOO is 1398 km 2 and the AOO is 20 km 2, both count as “Endangered”. The AOO is based on a cell width of 2 km. This calculation of the EOO as one continuous area is much too high looking at the big gap between the most western occurrence and all other ones. Most specimens were collected in the Ankasa Reserve and that is the only forest area where this subspecies is found more than once. Most forests connecting the two locations of the subspecies has disappeared in recent years. Like for the species itself I propose “Endangered” for this subspecies (B1 & B2 ab(iii) IUCN 2015).

Remark

The holotype of G. luteocarpa sp. nov. was not recognized before as a Gaertnera species and for years misplaced in the herbarium as Bertiera racemosa (G.Don) K.Schum.
