It is similar to Bidens henryi but differs in having much shorter involucral bracts and in the large but variable number of heads among individuals, and it occupies drier and lower elevation habitats. Some of the collections of this species from Nuku Hiva seem to grade toward Bidens bipontina as they have more caudate leaf apices and longer rays (e.g., Florence 4332, 4353, and 4390 from Toovii Plateau area) than collections from other areas of Nuku Hiva and other islands. Specimens from the Terre Deserte, Haatuatua Valley (Gagné &amp; Montgomery 2463, 2471) have heads on the smaller end of the variation like some other collections from Nuku Hiva, but uniformly have compound leaves. Compound leaves occurs only in Haatuatua and the adjacent Tapueahu Valleys, and they are found in all three of the species that occur there (Bidens cordifolia, Bidens bipontina, and Bidens polycephala). Otherwise these species all have simple leaves. The only exception to this is the rare occurrence of compound leaves in Bidens microcephala on Fatu Hiva. This pattern could be the result of presence of compound leaves in populations of one of the three species and hybridization among them at some time in the past. Two collections are considered putative hybrids and are discussed below. Gillett (1972) used a collection (Gillett 2194) in his experimental studies of Pacific Bidens. He determined that Bidens polycephala was self-compatible and is capable of forming fully fertile F1 hybrids with several Hawaiian species (Bidens mauiensis (A. Gray) Sherff, Bidens menziesii (A. Gray) Sherff, and Bidens molokaiensis (Hillebr.) Sherff).</p> </div>	https://treatment.plazi.org/id/A1B013D41C6CA8DEBCEB5C8ED3DC28ED	Public Domain	No known copyright restrictions apply.

In several specimens (Price &amp; Wood 231, Wood &amp; Perlman 4539, Wood &amp; Price 10103, Perlman &amp; Wood 14996), this reduction is even more extreme; flower heads in these specimens contain consistently fewer than 4 florets each, often only two or even occasionally one. These latter specimens also universally exhibit entire to subentire leaf margins and might represent yet another evolutionary lineage worthy of formal recognition (e.g., in Lorence 7823, specimen from cultivated plant grown from seed from Perlman 14996).</p> </div>	https://treatment.plazi.org/id/B2EECB3C1C7353ACB54F537CC24C2D54	Public Domain	No known copyright restrictions apply.
