The American species of Trifolium section Lupinaster are reviewed. A key to the species, descriptions of species which have not been published already in previous papers (Gillett 1965, 1969, 1971, 1972), pertinent synonyms, typification, and distribution maps and notes are provided. The chromosome number 2n = 16 is reported as new for Trifolium douglasii House. A new subspecies, T. andersonii Gray subsp. beatleyae Gillett, is described and the following combinations are made: T. plumosum Douglas subsp. amplifolium (Martin) Gillett, T. gymnocarpon Nuttall subsp. plummerae (Watson) Gillett, T. andersonii Gray subsp. monoense (Greene) Gillett, and T. kingii Watson subsp. macilentum (Greene) Gillett. Morphological relationships are discussed.

AbstractThe systematics of Acalymma sensu stricto of North America including Mexico are revised. Acalymma sensu stricto is defined and distinguished from the other species groups of Acalymma. Sixteen species are discussed including four new species: A. blomorum, A. palomarense, A. invenustum, and A. luridifrons all from Mexico. Three new subspecies of A. blandulum (LeConte) are described: blandulum (LeConte) new status, nigriventre, and yucatanense. Acalymma coruscum costaricense Bechyné is placed as a synonym of A. innubum (Fabricius). Keys are presented to all species and subspecies. Habitus and male genitalia drawings are given for all species and distribution maps are given where appropriate.

Trichodesma R.Br. is a genus of about 45 species known from tropical and subtropical regions of Africa. Asia and Australia. The group comprises predominantly perennial herbs, the flowers characterized by anthers with prolonged connectives, often twisting above the thecae. and a prominent accrescent calyx. Five species and three subspecies of 7rii hodesma are currently recognized in southern Africa, with  T. angustifolium Harv. subsp. argenteum Relief A.E.van Wyk newly described. These taxa are widespread in southern Africa, occurring in various vegetation types. A key to the species, descriptions, distribution maps and illustrations of various micro- and macromorphological as well as palvnological features are provided.

Kanakomyrtus (Myrtaceae) is a newly described genus endemic to New Caledonia. Kanakomyrtus myrtopsidoides, the generic type, is transferred from Eugenia. Five new species are described: K. mcphersonii, K. revoluta, K. dawsoniana, K. prominens, and K. longipetiolata. The genus occurs in forests at elevations between 500–1,600 m on the relatively mesic windward side of the Grande Terre. It is distinct from other baccate genera of Myrtaceae by a combination of linear stylar lobes, densely glandular stamens and stigmas, and a short but densely hoary indumentum that is brownish when dry. The thinly membranous partitions that partially extend between the seeds of some species suggest a close relationship to Archirhodomyrtus and some species traditionally placed in Rhodomyrtus and Octamyrtus. Four of the six species have unisexual flowers, but much additional field work is needed to assess the reproductive biology of the genus. Following IUCN guidelines, four species are proposed as either Endangered or Critically Endangered, whereas the remaining species are considered Vulnerable and of Low Concern. Species descriptions, illustrations, distribution maps, and keys to species of the genus and related taxa of baccate Myrtaceae from New Caledonia are included.

The genus Synaxis is synonymized with Tetracis. The thirteen North American species in genus Tetracis (some formerly in Synaxis) are discussed, including descriptions of three new species from western North America: Tetracis australis, T. montanaria, T. pallidata. Two additional species, “Synaxis” triangulata and “S.” brunneilinearia are excluded. A key to species, descriptions, check list, illustrations of adults and genitalia, and distribution maps are included. The formerly presumed lost types of the taxa aurantiacaria, cervinaria, and jubararia were located and are illustrated.

A taxonomic review of Centaurea sect. Rhizocalathium Tzvelev and C. sect. Pseudoseridia Wagenitz in Iran was carried out. The latter, with only one species, Centaurea stevenii, is reported here as new to Iran. In Centaurea sect. Rhizocalathium, C. lasiorhiza is treated as a correct name, C. ispahanica subsp. sirjanensis is described as a new subspecies and C. ispahanica subsp. macrocarpa is proposed as a new combination. Finally, C. ispahanica is typified and its chromosome number is reported for the first time, and a new basic chromosome number for C. sect. Rhizocalathium is proposed.

The taxonomic treatment of Hirtella (Chrysobalanaceae) from Bahia State, Brazil, is presented. We recognize 14 species; H. bicornis is recorded for the first time in the state and H. prancei was originally described from this study. The treatment includes an identification key to species, descriptions and comments on taxa, as well as illustrations and geographic distribution maps of species in Bahia. An identification key to the genera of Chrysobalanaceae in the state is also provided.

Paspalum comprises 350 species worldwide and is the largest genus of Poaceae in Brazil (211 species). The reticulated evolutionary pattern within the informal Paspalum Plicatula Group makes it a challenging species complex to treat taxonomically. The present work aims to study the three annual species P. cordaense, P. macranthecium and P. plowmanii, characterized by spikelet morphology and anthecium appearance, supported by a comprehensive review of herbaria and fieldwork collections of all related species. When ascertaining the identity of P. cordaense, we realized that it is distinct from P. plowmanii, while these two species are closely related to P. macranthecium. These findings are supported by morphological differences and by the first report of unusual chromosome number for P. plowmanii 2n = 38, whereas the numbers in P. cordaense are 2n = 40 and in P. macranthecium 2n = 20, from previously published research. We clarify the circumscription of the three species and provide a key, descriptions, comments, illustrations, distribution maps and conservation status for all species. The lectotypification of P. cordaense is also proposed.

The palm genus Trithrinax is revised and three species and four varieties are accepted (T. brasiliensis var. brasiliensis, T. brasiliensis var. acanthocoma, T. campestris, T. schizophylla var. schizophylla and T. schizophylla var. biflabellata comb. nov.). This taxonomic treatment presents detailed and complete description of all taxa, based on the studies of natural populations in Argentina, Brazil and Paraguay, the morphological analysis of herbarium specimens (including all available types) and an exhaustive literature research. Illustrations are presented for all taxa and identification keys to the species and varieties are proposed. Species descriptions include updated distribution maps, information about their ecology, taxonomic notes and a compilation of common names and uses. The conservation status assessment reveals an important level of threatening for all taxa, ranging from vulnerable (VU) to endangered (EN), mainly due to the decline of the area of occupancy and the quality of habitat.
