A new species of Genlisea section Genlisea from the white-sand savannas (“campinaranas”) of Brazilian Amazon is described and illustrated, providing remarks on habitat and ecology as well as SEM seed images. Genlisea multiflora has been recorded from Viruá National Park, and is of affinity to the large, purple-flowered species G. sanariapoana and G. guianensis. An identification key to all Genlisea species north of the Amazon is presented.

A New Species

The new species Myrcia psammophila is here described, illustrated and compared with M. grandis and M. umbraticola, two morphologically similar taxa. It may be distinguished from these two latter species based on possession of leaves with corky petiole and raised midvein adaxially, and distinctly pedicellate flowers with squared staminal ring and sepals united at the base. This species is endemic to a region of lower Rio Negro and inhabits areas of white-sand vegetation.

Isertia psammophila, a new species from the white-sand campinarana forests in Northern Brazilian Amazonia is here described and illustrated. While molecular evidence indicates that it is closely related to I. rosea, I. parviflora and I. spiciformis, morphologically it is most similar to I. rosea by its short stipules and glabrescent leaves. Isertia psammophila occurs in sympatry with I. rosea and I. parviflora in the Viruá National Park, Roraima, Brazil, and these three species can be easily differentiated by morphological characters, which are here discussed.

Saxofridericia brasiliensis P.E.Berry & Krahl, a new species of Saxofridericia subgenus Acrotheca, is described and illustrated. It is most closely related to Saxofridericia aculeata Körnicke, but differs in its entire-margined leaves and narrower leaf blades. It is so far known only from white-sand campina vegetation north of Manaus along the Caracaraí highway in Amazonas State, Brazil.

Abstract We describe a new species of Thamnophilus antshrike—T. divisorius (Acre Antshrike)—from the Serra do Divisor of Acre, Brazil. The new species is known from a single small ridge (though we expect that it is present on other, unexplored ridges in the Acre Arch uplands), and is common in the interior of shrubby woodlands on poor soil physiognomically similar to white-sand habitats in the Guianas and Amazonia. Thamnophilus divisorius is sister to T. insignis (Streak-backed Antshrike), a narrow endemic of pantepui, and forms a wellsupported clade with that species and T. amazonicus (Amazonian Antshrike). Thamnophilus divisorius occurs in a remote region within a national park in Brazil; despite its limited range, we are optimistic about its future survival.

The new species Platycarpum loretensis (Rubiaceae) is endemic to the Loreto Department, Peru, and restricted to white sand forests (varillal), palm swamps, and peatlands. It is similar to P. orinocense from which can be separated by the oblanceolate leaves with prominulous intersecondary veins (vs. elliptic to ovate, without intersecondary veins), corollas 1.9–3 cm long (vs. 1.2–2(–2.2) cm long), and fruits 4.7–5.5 × 3.6–4.9 cm (vs. 3–3.5 × 2.8–3.5 cm).

Phithecellobium prancei, related to T. simabifolium Benth. and P. spruceanum Benth., is described and figured from specimens collected on white sand savannas along rio Aracá in northern Amazonas, Brazil. Its relationships within sect. Samanea ser. Coriaceae Benth., a group due for generic segregation from Pithecellobium sens. lat., are discussed.

A New Species

Pagamea spruceana, a new species from Northwestern Amazon, Brazil, is endemic to the Upper Rio Negro region, in the Içana and Uaupés River Basins, and differs from other functionally dioecious species of Pagamea by its capitate and puberulous inflorescences and narrowly elliptic leaf blades with revolute and puberulous margins. Pagamea spruceana is the only species in the genus known from long-term inundated habitats (igapós) in the Amazon. The new species is here described and the affinities with morphologically similar and closely related species are discussed.
