<Emphasis Type=Italic>Croton limae</Emphasis> (Euphorbiaceae), a new species of section <Emphasis Type=Italic>Argyroglossum</Emphasis> from northeastern Brazil

A new species in Croton section Argyroglossum from northeastern Brazil is described and illustrated. Croton limae was previously confused with C. tricolor and C. argyrophyllus, which are the most closely related species. Its geographic distribution is discussed and a key to distinguish these three related species is presented.     

<Emphasis Type=Italic>Gagea robusta</Emphasis> (Liliaceae), a new species from <Emphasis Type=Italic>Flora Iranica</Emphasis> area

A new species, endemic to the Flora Iranica area, Gagea robusta (Liliaceae) is described and illustrated. It differs from G. reticulata (Pall.) Schult. & Schult. f. in having a puberulent indumentum on the basal leaf and from G. setifolia Baker ex Aitch. in having a long neck (up to 12 cm long). Its ecology, distribution and conservation status are discussed.     

<Emphasis Type="Italic">Stylogyne carautae</Emphasis> (Myrsinaceae), a new species from south-eastern Brazil

Stylogyne carautae Carrijo & M. F. Freitas is described and illustrated as a new endemic species from south-eastern Brazil. The relationships between S. carautae and S. depauperata Mez are discussed, and comments on their ecology and conservation are provided.     

<Emphasis Type=Italic>Capparidastrum tuxtlense</Emphasis> (Capparaceae), a new Mexican endemic

We describe and illustrate Capparidastrum tuxtlense, a narrow endemic, known only from the eastern slopes of Volcán San Martín, (10–450 m), Veracruz, Mexico. Capparidastrum tuxtlense is similar to Capparidastrum discolor, but differs by foliar, floral, and fruit characters. A discussion of putative relatives and a key to the Central American species of Capparidastrum are included.     

Two new species and a new combination in <Emphasis Type=Italic>Conchocarpus</Emphasis> (<Emphasis Type=Italic>Rutaceae,Galipeeae</Emphasis>) from eastern Brazil

Two new species of Rutaceae, Conchocarpus hamadryadicus Pirani & Kallunki and C. minutiflorus Groppo & Pirani are described and illustrated. Both are known so far only from small remnants of forests, the former in the caatinga dominium in Bahia, the latter in moist forests near Santa Teresa, Espírito Santo, Brazil. Their main diagnostic features are delineated, and their relationships to other species of Conchocarpus are discussed. Because Rauia racemosa Nees & Mart. can no longer be recognised as a synonym of Conchocarpus fontanesianus (A. St.-Hil.) Kallunki & Pirani, a new combination, C. racemosus (Nees & Mart.) Kallunki & Pirani, is provided, with comments.     

Three new species of <Emphasis Type=Italic>Eupatorieae</Emphasis> (Compositae) from Brazil

Three new species of Eupatorieae (Asteraceae) were collected in the “campos rupestres” of the Cadeia do Espinha?o, Minas Gerais state, Brazil, in the Itacolomi State Park, located between the cities of Ouro Preto and Mariana, Minas Gerais, Brazil, during a floristic survey focusing on Compositae in this area. Eupatorium semiamplexifolium, Mikania badiniana, and Stevia alexii are described and illustrated.     

<Emphasis Type=Italic>Trixis forzzae</Emphasis> (Compositae: Mutisieae), a new species from Minas Gerais,Brazil

The new species Trixis forzzae Borges & Saavedra, from Serra do Ibitipoca, Minas Gerais, Brazil is described and illustrated. Taxonomic relationships with similar species and those of similar geographical distribution are discussed.     

<Emphasis Type=Italic>Passiflora cristalina,</Emphasis> a striking new species of <Emphasis Type=Italic>Passiflora</Emphasis> (Passifloraceae) from Mato Grosso,Brazil

A new red-flowered species of Passiflora, P. cristalina Vanderpl. & Zappi, is described from the tropical rainforest of Mato Grosso, Brazil. The species is illustrated and its affinities with related species are discussed, and a key to the species of supersect. Distephana to which it belongs is provided.     

<Emphasis Type=Italic>Dombeya gautieri</Emphasis> (Dombeyaceae), a remarkable new species from Madagascar

Dombeya gautieri Dorr & Skema sp. nov. is described from Madagascar and illustrated. It is remarkable for its pinnatipartite leaves, reduced number of fertile stamens, petaloid staminodes, deeply divided style, and minute, 2-carpellate ovary.
