Thismia Griff. (Thismiaceae) is a holo-mycoheterotrophic genus with more than 100 species. In this study, phylogenetic analyses supported that T. malipoensis from Yunnan is a new species in T. sect. Glaziocharis. Morphologically, this new species can be distinguished from its phylogenetic sister species T. abei by having the annulus of the flower expanded and modified into a cucullate (hood-like) structure with zygomorphic symmetry with one opening on one side. Biogeographical inference showed that SW China to Indo-Burma and the Sunda Shelf region was suggested as the ancestral distribution region of Thismia s.s., then eastward to SE China and Japan, and southward to New Guinea to Australia, respectively. The Chinese species should have originated from at least two different ancestral sources, and geographical isolation caused the divergence between T. malipoensis and T. abei at 17.47 Mya.

Some amendments of our knowledge of the taxonomically complex genus Limonium (Plumbaginaceae) in Crete, Greece are presented, based on field work and morphological study of herbarium specimens, including types. The circumscriptions of the closely related Cretan endemics L. cornarianum and L. hierapetrae are clarified. The former species is actually restricted to the type population in Moni Kapsa (SE Crete) and a newly found population in Pacheia Ammos (NE Crete). The latter species comprises populations in SE Crete that extend from Moni Kapsa to Dermatos, and also includes the populations previously assigned to L. chrisianum and L. minoicum that are found to be conspecific. Limonium artelariae from SE Crete, similar and related to L. cornarianum and L. hierapetrae, is described as a new species. It is rather unique among Greek Limonium species for its height (up to 110 cm tall) and its large, broadly spathulate leaves. Limonium cythereum previously known from the islands of Kythira and Antikythira is newly recorded for Crete, represented by two populations in NW Crete. The report of L. fragile from Crete is found to be erroneous, based on misidentified material of L. virgatum. All accepted taxa are described, and their types, chromosome number or ploidy level, distribution and ecology are also indicated. Photographs, distribution maps and an identification key are added to facilitate further identification.

Serra do Padre Ângelo, a quartzitic massif in eastern Minas Gerais, Brazil, was nicknamed “Land of Giants” due to the gigantism observed in some plant species found in its campos rupestres. During fieldwork for the floristic inventory of this Serra, a small Eriocaulaceae species was collected. Initially it was believed to be a new species, but a thorough revision of names and type specimens revealed that it was conspecific with Paepalanthus minimus. This taxon was known only from the type specimen collected over 100 years ago and more than 200 km distant from the new collections. It had been overlooked in previous studies dealing with the family in Brazil, which could be explained by its diminutive size and the poor conditions of the type specimen. Here we present the implications of this rediscovery, including the combination of P. minimus in Giuliettia, a genus recently proposed based on general habit, inflorescence and seed morphology. We also present information on distribution and ecology and briefly discuss the biogeographical pattern that could explain this rediscovery far away from the previous record. Considering its likely local extinction at the type locality and threats to the quality of its remaining habitat, the species is preliminarily assessed as Critically Endangered. This highlights the urgent need for conservation actions to protect Serra do Padre Ângelo and its unique biodiversity.

A Serra do Padre Ângelo, um maciço quartzítico no leste de Minas Gerais, Brasil, foi apelidada de “Terra de Gigantes” devido ao gigantismo observado em algumas espécies de plantas encontradas em seus campos rupestres. Durante o trabalho de campo para o inventário florístico desta Serra, uma pequena espécie de Eriocaulaceae foi coletada. Inicialmente, acreditava-se ser uma nova espécie, mas uma revisão minuciosa dos nomes e espécimes tipo revelou que ela era na verdade conspecífica com Paepalanthus minimus. Esse táxon era conhecido apenas pelo espécime tipo, coletado há mais de 100 anos e a mais de 200 km das novas coletas, tendo passado despercebido em estudos anteriores sobre a família no Brasil, o que pode ser explicado pelo seu tamanho diminuto e pelas condições precárias do espécime tipo. Aqui, apresentamos as implicações dessa redescoberta, incluindo a combinação de P. minimus em Giuliettia, um gênero recentemente proposto, com base em seu hábito geral, morfologia da inflorescência e da semente. Também fornecemos informações sobre a distribuição e ecologia, e discutimos brevemente o padrão biogeográfico que poderia explicar essa redescoberta tão distante do registro anterior. Considerando sua provável extinção local na localidade tipo e as ameaças à qualidade de seu habitat remanescente, a espécie é preliminarmente avaliada como Criticamente em Perigo. Isso destaca a necessidade urgente de ações de conservação para proteger a Serra do Padre Ângelo e sua biodiversidade única.

The Astereae subtribe Madagasterinae (Asteraceae) sensu Nesom encompassing four Malagasy genera (Apodocephala, Madagaster, Rochonia and Vernoniopsis) is polyphyletic, as Apodocephala is a member of the Malagasy subtribe Lowryanthinae of the tribe Athroismeae. While Madagaster was shown to belong to Astereae, the phylogenetic positions of Rochonia and Vernoniopsis (now Jalantzia) in this tribe remained to be tested with molecular data. Lowryanthinae presently contains Apodocephala with nine species and the monospecific Lowryanthus. The monophyly of Apodocephala remained to be assessed using a comprehensive sampling. The aims were to: (1) assess the phylogenetic placements of Rochonia and Jalantzia (Vernoniopsis) and test the monophyly of Jalantzia; (2) assess phylogenetic relationships within Lowryanthinae; and (3) re-assess the subtribal and generic limits within the tribe Athroismeae. New phylogenetic analyses based on plastid sequence data confirmed the position of Rochonia in Astereae. Jalantzia (Vernoniopsis) was resolved as sister to the subtribe Lowryanthinae and therefore transferred to Athroismeae. A new subtribe, Jalantziinae, is described to accommodate Jalantzia. Apodocephala is paraphyletic with respect to Lowryanthus, which is formally merged with Apodocephala. A description of the emended subtribe Madagasterinae containing Madagaster and Rochonia is presented.
