Etymology — The epithet contracta is an allusion to the reduced inflorescence. Distribution— It occurs in Mexico , Venezuela , Peru and Brazil . In Brazil , it is found in the States of Roraima and Goiás and in the coastal states of the northeastern and southeastern regions of the country. It is the species with the broadest distribution in south-eastern Brazil , and it is the best represented species of the genus in herbaria of this region. There is a single record ( Ule 8419 ) for the State of Roraima , indicating a disjunction in the distribution of this species in Brazil , as Roraima is part of a continuous range that comprises the Antilles and Venezuela . Note— Wissadula contracta prefers extremely disturbed areas, such as road margins, trails, and rural areas, which could explain the lack of sampling in states such as Amapá , Amazonas , Pará , and Maranhão . This species is identified through its cordate to cordate-lanceolate leaves, 2 to 3 reduced leaves on the distal region of the branches, cylindrical congested inflorescences with a reduced main axis, white to beige corolla and a mericarp of inconspicuous constriction. In the vouchers Xavier 327 and Krapovickas 12899 , from northeastern Brazil , the fruits are remarkably large (ca. 10 mm in diameter), which is a rare characteristic for this species. Madagascar was recorded as the origin for the type specimen ( Schomburgk 849 ). However, according to Fryxell (1988) , only the seeds came from this country, and they were germinated and cultivated at the Berlin Botanical Gardens, where sampling of the type specimen was performed, and the voucher was deposited in B. The original description of W. contracta shows a weak depiction with lack of consistent characteristics when compared with the descriptions of accepted synonyms. However, analysis of the type specimens and arguments presented by Waalkes (1966) and Fries (1908) made it possible to confirm the synonymy for this species. A neotype was chosen by Fryxell (2002) for W. contracta as a consequence of the destruction of the holotype and absence of extant isotypes . The chosen specimen is well preserved and it is, is consistent with the original description, and it has duplicates. The origin of this species in the Old World is inaccurate. When Hochreutiner (1955) described the Madagascar flora, he did not include W. contracta . However, other floras of the Old World, such as those from Java ( Backer 1963 ) and Malaysia ( Waalkes 1966 ), mentioned the cultivation of this species in the region for fiber production. In the flora of India ( Sivarajan & Pradeep 1996 ), W. contracta was also not mentioned. Fries (1908) made a comment on Master’s observation (1874): “…cultivated in India and in Ceylon ; it’s native country is not known….” De Candolle (1824) affirmed that one of its synonyms, W. lechenaultiana , was cultivated in the Garden of Lechenault, Calcutta. In American floras, such as those of Mexico ( Fryxell 1988 ), Guatemala ( Standley and Steyermark 1949 ), Argentina ( Krapovickas 1997 ), and Brazil (Bovini 2012), this species is cited as spontaneously occurring in several regions. Therefore, we suspect that the material for the type specimen collected in Madagascar was from an individual introduced into that country, and in fact, it could have come from America, where it is widely distributed. When Schumann (1891) described W. hernandioides , he observed three specimens that correspond to W. contracta within the material including Schomburgk 849 , Pohl 1307 , and Glaziou 12450, but the types of indumentum, inflorescence and color of the flowers distinguish these species from each other.
