Remarks

Material at BRI (seen by me on loan at HO in December 2000) consists of two sheets: the lectotype has broken leaf material, flowers and fruits, and a typed sheet with the description from Walker (1948), and the isolectotype has mostly whole, detached leaflets and two packets. Both sheets have previously been labelled “ holotype ”.

The four sheets of Walker’s collection that I have seen all have labels from Queensland Herbarium, and although the collection number indicates “BSIP”, this specimen does not belong to the BSIP number series of the herbarium in Honiara (BSIP), which was not founded until 1965 ( Holmgren et al. 1990). Some later collections of this species, however, are numbered in the Honiara series.
