“…For example, the high species diversity in the California Floristic Province is associated with lower rates of extinction more than elevated speciation or immigration, using models in which rates of lineage birth, death, and movement are dependent on geographic occupancy but not time (53). Assembly of the Cerrado biome in Brazil has been characterized by recent (late Miocene onward) in situ adaptation of lineages to fire resistance (54), with some clades, especially in the campos rupestres highlands, showing evidence of endemic radiation [e.g., Mimosa (54,55), Calliandra (56), and Chamaecrista (57)]. In the Páramo biome of the Andes, analyses of net diversification (but not immigration) yielded the highest average rate compared with eight other hotspots and appear driven more by Pleistocene climate oscillations than orogeny (58).…”

A common hypothesis for the rich biodiversity found in mountains is uplift-driven diversification-that orogeny creates conditions favoring rapid in situ speciation of resident lineages. We tested this hypothesis in the context of the Qinghai-Tibetan Plateau (QTP) and adjoining mountain ranges, using the phylogenetic and geographic histories of multiple groups of plants to infer the tempo (rate) and mode (colonization versus in situ diversification) of biotic assembly through time and across regions. We focused on the Hengduan Mountains region, which in comparison with the QTP and Himalayas was uplifted more recently (since the late Miocene) and is smaller in area and richer in species. Time-calibrated phylogenetic analyses show that about 8 million y ago the rate of in situ diversification increased in the Hengduan Mountains, significantly exceeding that in the geologically older QTP and Himalayas. By contrast, in the QTP and Himalayas during the same period the rate of in situ diversification remained relatively flat, with colonization dominating lineage accumulation. The Hengduan Mountains flora was thus assembled disproportionately by recent in situ diversification, temporally congruent with independent estimates of orogeny. This study shows quantitative evidence for uplift-driven diversification in this region, and more generally, tests the hypothesis by comparing the rate and mode of biotic assembly jointly across time and space. It thus complements the more prevalent method of examining endemic radiations individually and could be used as a template to augment such studies in other biodiversity hotspots.biogeography | vascular plants | molecular clocks | dispersal | speciation C entral to understanding global patterns of biodiversity are considerations of biotic assembly: For a given region, when and how did resident species accumulate? Of primary interest is tempo (the rate of accumulation) and mode (the process, whether by colonization via dispersal or in situ lineage diversification). We wish to know how and why these vary in time and space.For mountains, well-known for harboring a disproportionate fraction of terrestrial species, a common hypothesis is that of uplift-driven diversification-that orogeny creates conditions favoring in situ speciation of resident lineages (1-6). Among global biodiversity hotspots, the mountain ranges surrounding the Qinghai-Tibetan Plateau (QTP) are unusual and enigmatic: They harbor one of the world's richest temperate floras, and (unlike other hotspots) they are neither tropical nor Mediterranean in climate. Moreover, despite increasing interest from biogeographers, their biotic assembly remains poorly understood (3, 4, 7). The mountains form three distinct hotspots of biodiversity that respectively lie to the west, south, and east of the QTP's central high desert: the Central Asian mountains (Altai and Tianshan ranges), the Himalayas, and the Hengduan Mountains region (4) (Fig. 1). Of these, the richest in plant diversity is the Hengduan Mountains, with a vascular flor...

ResumoIngeae é uma importante tribo da família Leguminosae com cerca de 950 espécies em 36 gêneros, dos quais 24 são endêmicos do Novo Mundo. Este trabalho apresenta o estudo florístico de 16 espécies de Ingeae, reunidas em sete gêneros: Abarema (seis spp.), Albizia (duas spp.), Calliandra (duas spp.), Chloroleucon (duas spp.), Enterolobium (duas spp.), Leucochloron (uma sp.) e Zygia (uma sp.) ocorrentes no Espírito Santo. O gênero Inga, devido ao grande número de espécies, será publicado posteriormente. Dentre as espécies estudadas, 14 (88%) são endêmicas do Brasil, sendo uma, Abarema barnebyana, restrita ao Espírito Santo e sete (44%) restritas ao bioma Floresta Atlântica. No estado, 14 espécies ocorrem em Floresta Ombrófila Densa. Na Restinga, são encontradas oito espécies e na Floresta Estacional Semidecidual, sete espécies. São apresentadas chaves para identificação, descrições, ilustrações, comentários taxonômicos, períodos de floração e frutificação, distribuição geográfica e habitats preferenciais. Palavras-chave: clado Mimosoide, Fabaceae, Floresta Atlântica. AbstractIngeae is an important tribe of Leguminosae with 950 species in 36 genera, 24 endemic to the New World. This manuscript is the florist treatment of 16 species of Ingeae, organized in seven genera: Abarema (six spp.), Albizia (two spp.), Calliandra (two spp.), Chloroleucon (two spp.), Enterolobium (two spp.), Leucochloron (one sp.) e Zygia (one sp.) in the state of Espírito Santo. The genus Inga will be discussed in a forthcoming manuscript, due to its number of species. Among the recorded species, fourteen (88%) are endemic to Brazil and Abarema barnebyana is restricted to Espírito Santo. Seven species (44%) are restricted to the Atlantic Forest biome. Fourteen species occurs in the Dense Rain Forest, eight species are found in the Restinga, and seven species in the Seasonal Semidecidual Forest. Identifications keys, descriptions, illustrations, taxonomic comments, flowering and fruiting periods, geographic distribution, and habitats are provided.

“…As stated by Guinet & Hernández (1989), Hernández (1989) and Barneby (1998), the genus is characterized by a combination of characters, namely the elastically dehiscent pods, the 8-grained, bisymmetric, calymmate polyads with a mucilaginous basal appendage, and the atypical chromosome numbers (n = 8 and 11). Souza et al (2013) carried out a phylogenetic analysis using morphological and molecular data [nrDNA (ITS) and cpDNA (trnL-F)], concluding that the American species of Calliandra, including genus Guinetia L. Rico & M. Sousa (1999: 977) later transferred to Calliandra [C. tehuantepecensis (L. Rico & M. Sousa) E.R. Souza L.P. Quieroz (2013: 1215], form a monophyletic group.…”

A new species of Calliandra (Leguminosae, Mimosoideae, tribe Ingeae) from a restricted locality of Campeche, Mexico is herein described and illustrated. The species appears to be closely related to C. molinae, a species from Honduras, El Salvador and Nicaragua, from which it may be distinguished by being allopatric, and by a more limited development of suberose bark in stems and branches, comparatively smaller leaflets, consistently glabrous leaflets and corollas, and by the scarcely villous pods. Calliandra mayana appears to be restricted to an extremely small seasonally flooded savannah surrounded by tropical deciduous forest and, based on IUCN criteria, it is provisionally considered Critically endangered. ResumenSe describe e ilustra una nueva especie de Calliandra (Leguminosae, Mimosoideae, tribu Ingeae) de una localidad restringida de Campeche, México. La especie parece estar íntimamente relacionada con C. molinae, que habita en Honduras, El Salvador y Nicaragua, de la cual se puede distinguir por ser alopátrica, por el desarrollo muy limitado de tejido suberoso en tallos y ramas, por los folíolos comparativamente más pequeños, por los folíolos y corolas consistentemente glabros, y por las vainas escasamente villosas. Calliandra mayana parece estar restringida a una pequeña sabana estacionalmente inundable rodeada de bosque tropical deciduo, y se le considera provisionalmente Críticamente amenazada, de acuerdo con los criterios de la Unión Internacional para la Conservación de la Naturaleza.
