Luzon, Province of Benguet, Baguio, Elmer 8916. This species presents a 

 most puzzling problem, as it is an almost perfect match for G. triandrum, both 

 in its vegetative and floral aspects, except that it has 5 stamens. It was originally 

 so described, and the single male flower upon the specimen in this herbarium 

 confirms the statement. In an examination of a very large number of flowers of 

 this genus, belonging to many species, plants have been found with either 3 or 4 

 stamens in different flowers, others with either 4 or 5, the former set sometimes 

 also with 2, the latter with 6, but in no single instance have 3-anthered and 

 5-anthered flowers been found on the same plant. This is the basis for the 

 separation of the sections Euglochidion and Hemiglochidion, and the distinction 

 elsewhere holds well for Philippine material. As between G. quinquestylum and 

 G. triandrum, I can not find a single other character, unless that of the pubescence 

 of the ovary and branchlets; in size, shape, texture, pubescence, petioles, and 

 venation of the leaves, perianth, styles, capsules, seeds, no difference can be 

 detected. The ovary is described as glabrous, all those on the specimen here have 

 passed the early stages and the youngest of them are slightly pubescent, as are
