New Nomenclatural Combinations

The recent molecular investigations by Kool et al. (2007) clearly showed the polyphyly of the genus Polycarpon Linnaeus (1759: 859, 881) which includes, in the new restricted sense, only the taxa belonging to the Polycarpon tetraphyllum clade, while the South American P. suffruticosum Grisebach (1874: 77−78), and P. coquimbense Gereau & Marticonema (1995: 154), and the widespread tropical P. prostratum (Forsskål 1775: 207) Ascherson & Schweinfurth (1889: 128) are to be excluded. Kool et al. (2007) also suggested treating all the members of the P. tetraphyllum group as a single species with the recognition of several subspecies. Accordingly, Iamonico (2013), and Iamonico & Domina (2015) proposed four new nomenclatural combinations [a further proposal about the northwestern American P. depressum Nuttal ex Torrey & Gray (1838: 174) is in preparation].

South American Species

We provide an illustrated catalog of the cyphophthalmid diversity of the Neotropics, including photographs of the holotypes and paratypes (when available) for all but one described South American Neogoveidae. These include the single species of Huitaca, two of the three Metagovea species, the four Neogovea species and ? Gen. enigmaticus. Furthermore we provide collecting data for 37 undescribed species of south American Neogoveidae, including Huitaca (8 spp.), Neogovea (12 spp.) and Metagovea (17 spp.). Distributional data of the species of Neogoveidae add the first records for French Guiana, Peru, Suriname, Trinidad and Tobago, and Venezuela. Colombia shows the largest diversity of Cyphophthalmi among South American countries, perhaps due to the large amount of ecosystems found in this country, but this could also reflect sampling effort.

Living Material

Two species of Gaultheria have been reported from the Caribbean: G. domingensis is said to occur on the Greater Antillean island of Hispaniola and G. sphagnicola, for which the specific names of G. buxifolia and G. anastomosans (both species occurring in South America) have been listed in synonymy, is said to occur on the Lesser Antillean islands of Martinique and Guadeloupe. A close examination of living material from Martinique and of herbarium specimens from Martinique, South America. Hispaniola, and Mexico reveals the following: (1) the Martinique and Guadeloupe group is specifically distinct from the South American G. buxifolia and G. anastomosans groups; (2) the Lesser Antilles group and the Greater Antilles group should be placed in a single species with the name of G. domingensis; and (3) there is evidence for a possible Mexican origin for this one Caribbean species.

Molecular Characters

Generic boundaries of the South American species Panicum longipedicellatum Swallen are explored and compared with allied genera of the tribe Paniceae. On the basis of morphological, anatomical, and molecular characters a new genus, Cnidochloa Zuloaga, is proposed. The phylogenetic position of the new genus within the Paniceae is evaluated.
