Magnoliaceae of Guatemala are summarized, and two new Guatemalan species from Alta Verapaz are described and illustrated. Two Magnolia occurrence records are added to the flora of this country. Magnolia archilana is similar to M. hondurensis, but it differs from the latter in having glabrous terminal twigs, petioles, spathaceous bracts, peduncles and carpels, broadly obovate leaves, longer peduncles and larger sepals, outer petals and polyfollicles. Magnolia tribouillierana resembles M. montebelloensis but differs from the latter in lacking branches below five metres; in having glabrous twig internodes, spathaceous bracts and carpels, more numerous leaf veins per side, longer longest peduncular internode, abaxially yellowish sepals, fewer spathaceous bracts and more numerous carpels. A key to species and a distribution map of native Guatemalan magnolias is also provided. Data on diversity, endemism, ethnobotanical knowledge and conservation are also provided. Using the IUCN criteria, conservation status of M. archilana and M. tribouillierana are here assessed as endangered (En) and critically endangered (CR), respectively. Conservation actions are urgently needed for the six Guatemalan magnolias faced with extinction.

Three new Magnolia species and a new record from Guatemala are described and illustrated. Two of the new species, M. javieri and M. oscarrodrigoi, are from Alta Verapaz Department and one, M. veliziana, is from Quiché Department. Additionally, M. faustinomirandae is newly reported for the flora of Guatemala. With this contribution, the number of native Guatemalan species increases from 11 to 15 species. An updated distribution map and a key to species are provided. Guatemala, particularly the north-wet-arc in the Maya Highlands, is now an important centre of diversification and endemism for Magnolia. The conservation status of the newly proposed species was unofficially assessed using IUCN criteria.

A new species of Magnolia from the southern Sierra Madre Oriental, Mexico, is described and illustrated, providing information about its habitat distribution, ecology, biogeography and conservation status. After 12 fieldwork expeditions near the border of the states of Hidalgo and Puebla, we have developed morphological, ecological and biogeographic data to support recognition of populations from Acaxochitlán, Hidalgo and Pahuatlán, Puebla as a distinct species of Magnolia sect. Macrophylla. A key to species of this section and a distribution map for Mexican taxa are provided. The species was assessed as critically endangered (CR).

This contribution presents and describes Siphocampylus baccae and S. sevegnaniae, two narrowly endemic new species from waterfalls and rocky cliffs in Santa Catarina state, southern Brazil. We assess the conservation status of both species as critically endangered (CR) according to the IUCN criteria. We present descriptions, photographs, a distribution map and taxonomic comments on the new species along with an identification key to the species of Siphocampylus that occur in Santa Catarina.

Magnolia lozanoi is rediscovered 26 years after being collected for the first time. Herbarium specimens were collected by Al Gentry in 1993 and formally described by Antonio Vázquez and Ernesto Castro in 2012. This species is known only from El Quimi Biological Reserve in the province of Morona-Santiago, southeastern Ecuador. An emended description, distribution map and the first photographs of this species are provided. Additionally, its relationships with other species are discussed. Its conservation status is proposed as critically endangered (CR) according to IUCN criteria.

Scorzonera amasiana Hausskn. and Bornm. was described from type specimens collected by J.F.N. Bornmueller in 1889 but it was not collected again until 1993, when it was found near Amasya, Turkey. Populations of S. amasiana were quite small at that limited locations and were vulnerable to human impacts. Therefore, suitable conservation strategies should be developed immediately in order to protect the species from probable extinction. Here, an additional three small populations are reported. Brief history, morphology, habitat and ecology of this endemic species have been discussed. Its current conservation status was reevaluated with respect to the latest IUCN criteria. A key to distinguish it from the other closely related Turkish species is also provided and its distribution map is appended.   Key words: Endangered, Rediscovery, Scorzonera, Turkey DOI = 10.3329/bjb.v36i2.1502 Bangladesh J.

We describe here Begonia medeiroii, a narrow endemic species from the Atlantic Rainforest. The conservation status of this species was assessed as critically endangered according to IUCN criteria. This species resembles to B. catharinensis and B. hirtella in some characteristics, differing among other features due the presence of adventitious vegetative buds on the adaxial surface of the leaves.

Turkish endemic taxon Onopordum bracteatum Boiss. & Heldr. var. arachnoideum Erik & Sümbül is transferred to O. myriacanthum Boiss. as O. myriacanthum subsp. arachnoideum (Erik & Sümbül) P?nar & Behçet comb. & stat. nov. It is characterized by the phyllaries with densely and persistently arachnoid hairs both inside and outside, and upper stem leaves are 2–8 cm far from capitulum. In addition, the pollen characteristics and achene features are presented. The conservation status of O. myriacanthum subsp. arachnoideum has been assessed according to IUCN criteria. A distribution map of O. myriacanthum subsp. arachnoideum and its related taxa is also presented.DOI: http://dx.doi.org/10.3329/bjpt.v21i2.21352Bangladesh J.

The Brazilian savanna (Cerrado domain), although without significant richness of Chrysobalanaceae, has widely distributed species of this family, and some endemic to this domain. Couepia, a Neotropical genus, includes 62 species distributed mainly in lowland tropical forests with three species recognized for the Brazilian savanna. Here we report a new species of Couepia endemic to Brazilian savanna in the region with the greatest agricultural advance in Brazil, from the states of Tocantins and Goiás. We provide a description, a distribution map, photographs, a preliminary conservation status assessment and comparisons with other species of the genus that occur in this domain. With this addition we help to contribute to the knowledge of plant biodiversity, which is an urgent and fundamental step towards planning and carrying out conservation actions.

Apios chendezhaoana, a new combination derived from Sinolegumenea chendezhaoana, is recognized by both morphological and molecular evidence. It is a new member within Apios, and it is also an endemic and endangered species from East and South China. Phylogenetic analyses indicate that it could be sister to A. fortunei, but morphologically it differs from all its allies by its broad triangular leaflets with caudate apices, white corolla, pink markings on the lower part of the keel, and dilated style with tufted hairs beneath the stigma. We provide a detailed description, photographs, illustrations, and distribution map. We also estimate its conservation status according to IUCN criteria. A key to Apios is also provided, together with a brief revision.

We propose that two populations previously referred to Hechtia epigyna, from the Mexican state of Hidalgo, represent a new species. Plants from the Hidalgo populations share the inferior ovary with Hechtia epigyna, an unusual trait in the genus, but they differ in their growth pattern (central vs. lateral inflorescence), characters of the adaxial foliar surface, petal color, and fruit position during dehiscence. We also provide a clarification on the typification of Hechtia epigyna. An assessment of the conservation status of the new species, Hechtia deceptrix following IUCN criteria resulted as CR (Critically Endangered).
