2978. Gilg, Ernst. Die bis jetzt aus Neu-Guinea bekannt gewordenen Flacourtiaceen. 

 [The known Flacourtiaceae of. New Guinea.] Bot. Jahrb. 55:273-294. 9 fig. 1918.— Few 

 species of the Flacourtiaceae have been previously known from New Guinea, and these were 

 mostly described in recent years. The family plays an insignificant role in the vegetation 

 formations. It is of interest that with the exception of Casearia none of the larger genera 

 of this family are represented here by many species. All the genera belong to the indo- 

 malaysian floral region. No keys are given. Critical notes on structure distribution and 

 synonomy are presented. The following genera are treated, with the appended number of 

 species in each: Erythrospermum, lsp., Hydnocarpus, lsp., Scolopia, lsp., Homalium, 3sp., 

 Xylosma, lsp., Flacourlia, 3sp., Doryalis, lsp., Bennettia, lsp., Osmelia, lsp., Casearia, 

 9 sp. The following species are described as new: Homalium amplifolium, H. pachyphyllum, 

 H. acutissimum, Xylosma papuanum, Doryalis macrodendron, Bennettia papuana, Casearia 

 Ledermannii, C. urophylla, C. pachyphylla, C. anisophylla, C. globifera, C. macrantha, and 

 C. brunneo-striata. Homalium Gilgianum Laut. is shown to be in reality Lophopyxis pentap- 

 tera (K. Sch.) Engl. It belongs neither to the genus Homalium of the Flacourtiaceae nor to 

 the Uhamnaceae which it very much resembles, but to the Icacinaceae. The position of the 

 genus Gerlrudia K. Schum. is discussed, and it is shown not to belong to the Flacourtiaceae.
