As follows from the key provided by Gagnepain & Beille (1927) , Glochidion geoffrayi is distinct from its morphologically similar congeners mainly by the hairy stylar column ( Fig. 3E–G ). Glochidion geoffrayi differs from G. anamiticum ( Kuntze 1891: 601 ) Kuntze ex Merrill (1936: 195) (including G. annamense Beille 1927: 627 ), which also possesses a hairy stylar column, by longer styles with respect to the stylar column: the style/stylar column ratio is more than 2 in G. geoffrayi ( Gagnepain & Beille 1927 : Fig. 74-14) and about 1.5–2 in G. anamiticum ( Gagnepain & Beille 1927 : Fig. 74-19, Yao et al. 2018 : Fig. 2A ).
