Two new micro-endemic species of Eriocaulaceae are described from the Campos Rupestres of Serra Nova State Park, a conservation unit located in the Espinhaço Range in northern Minas Gerais state, Brazil. Herein we provide descriptions, illustrations, photographs and maps, together with notes on morphology, distribution, phenology, taxonomy, and conservation. Paepalanthus ferrugineus is distinguished mainly by the reddish-brown involucral bracts, surpassing the floral disc, with the apex attenuate and tufted adaxially, tufted sepals and hairy petals. Syngonanthus polyaxis is easily differentiated by the inflorescence architecture with three morphologically distinct axial parts. Both species are considered Critically Endangered according to the IUCN Red List criteria.

Three New Species

We describe and illustrate three new species of Paepalanthus (Eriocaulaceae: Paepalanthoideae) from the Espinhaço Range: P. argyrotrychus, P. farinaceus and P. velutiphyllus, all endemic to Serra do Ambrósio, a mountain disjunct from the Espinhaço Range in the municipality of Rio Vermelho, Minas Gerais, Brazil. These species belong to Paepalanthus ser. Paepalanthus (=Paepalanthus [unranked] Variabiles). We provide detailed descriptions and illustrations for each taxon, as well as comments on habitat, distribution, morphology, conservation and their affinities to the most morphologically similar species.

Three populations of <em>Abies cilicica</em> subsp. <em>isaurica</em> and four of <em>A. cilicica</em> subsp. <em>cilicica</em> were analyzed using 35 morphological and anatomical needle characters with the implementation of multivariate statistical methods to verify the differences between subspecies. Moreover, the possible geographic differentiation of <em>A. cilicica</em> subsp. <em>cilicica</em> populations from the East Taurus and Lebanon Mountains was examined. <em>Abies cilicica</em> subsp. <em>isaurica</em> has been distinguished from <em>A. cilicica</em> subsp. <em>cilicica</em> by its glabrous young shoots and resinous buds. We detected that needles of <em>A. cilicica</em> subsp. <em>isaurica</em> are longer, broader and thicker, with a higher number of stomata rows, and larger cells of the epidermis, hypodermis and endodermis than <em>A. cilicica</em> subsp. <em>cilicica</em>. Additionally, <em>A. cilicica</em> subsp. <em>isaurica</em> needles have frequently rounded to obtuse-acute apex and resinous canals positioned more centrally inside the mesophyll than needles of <em>A. cilicica</em> subsp. <em>cilicica</em>. This indicates that a set of most of the tested needle characters can be used to distinguish the subspecies; however, any of characters enable that when used separately. Morphological and anatomical distinctiveness between these two taxa justify their recognition at the subspecies rank. Additionally, the populations of <em>A. cilicica</em> subsp. <em>cilicica</em> from the East Taurus and Lebanon are morphologically different. This geographic differentiation of populations is congruent with results provided by genetic analyses of nuclear microsatellites markers (nSSR).

Abstract—Solanum adamantium is described from Serra de Grão Mogol, located in the Espinhaço range, in northern Minas Gerais State, Brazil. The new species is ecologically and morphologically similar to the prickly species S. buddleiifolium and S. thomasiifolium, from which it differs in a series of vegetative and reproductive characters. We discuss the morphological similarities and differences among these species, as well as certain aspects of the new taxon’s ecology and geographic distribution. Images of diagnostic characters, a map of geographical distribution, a preliminary conservation assessment, and full specimen citations are provided.

Hells Canyon

Two Upper Triassic sphinctozoan sponges of the family Sebargasiidae were recovered from silicified residues collected in Hells Canyon, Oregon. These sponges areAmblysiphonellacf.A. steinmanni(Haas), known from the Tethys region, andColospongia whalenin. sp., an endemic species. The latter sponge was placed in the superfamily Porata by Seilacher (1962). The presence of well-preserved cribrate plates in this sponge, in addition to pores of the chamber walls, is a unique condition never before reported in any porate sphinctozoans. Aporate counterparts known primarily from the Triassic Alps have similar cribrate plates but lack the pores in the chamber walls. The sponges from Hells Canyon are associated with abundant bivalves and corals of marked Tethyan affinities and come from a displaced terrane known as the Wallowa Terrane. It was a tropical island arc, suspected to have paleogeographic relationships with Wrangellia; however, these sponges have not yet been found in any other Cordilleran terrane.
