[13] She published nine new species in 1990, in conjunction with Donald Robert Hodel -these are all southern Central American dwarf palms in the genus Chamaedorea.
[13][14] Along with Dransfield, and in one case Anthony Kyle Irvine, she also published a handful of recombinations, notably moving the monotypic African Wissmannia carinensis to the East Asian and Australian Livistona.
After the publication of their 1983 book Genera Palmarum, she and Dransfield formally described a number of the new infrageneric taxa proposed in it in a 1986 article.
[13] She is also credited as part of a large team which sequenced genetic code across the Arecaceae, and in 2005 created a few higher taxa to reclassify the infrageneric taxonomy.
[17] She also received the Robert Allerton Award from the National Tropical Botanic Garden in 2003 in recognition of her lifetime achievements in botany.
