Some species she went on to illustrate, press and describe included: "Phytolacca decandra" (now "P. americana"), "Polygala senega", "Erythronium americanum", "Ambrosia artemisifolia, Monarda didyma, and Clematis virginiana." In her section "Observat" (now known as observations) she pointing out to Linnaeus that "there are some plants of Clematis that bear only male flowers, this I have observed with such care that there can be no doubt about it". This shows the long hours she spent doing observations, which were consistent, accurate and replicable. Jane Colden documented her findings of an entirely new flora for her countrymen and for eager Europeans, and it is with this in mind that we can fully understand her delight in botany and appreciate her contribution.
