A new species of <Emphasis Type="Italic">Macroptilium</Emphasis> (Benth.) Urb. (<Emphasis Type="Italic">Leguminosae</Emphasis>: <Emphasis Type="Italic">Papilionoideae</Emphasis>: <Emphasis Type="Italic">Phaseolinae</Emphasis>) from North-Eastern Brazil

Summary  A new species of Macroptilium sect. Microcochle (Benth.) J. A. Lackey is herein described from the states of Piauí and Bahia, Brazil. Macroptilium cochleatum is characterized by few-flowered inflorescences, calyx teeth longer than the tube, a tightly four-coiled keel, and linear, patent fruits. The discovery of this unique Macroptilium species, with its distally coiled keel, expands the diagnostic features of the genus. A key to the Brazilian species of sect. Microcochle is provided.     

Three new species of <Emphasis Type="Italic">Passiflora</Emphasis> subgenus <Emphasis Type="Italic">Decaloba</Emphasis> (Passifloraceae) from Brazil

Three new species from Brazil are described and illustrated. Passiflora cervii, P. jiboiaensis, and P. transversalis all belong to Passiflora subg. Decaloba.     

A new species of <Emphasis Type="Italic">Panopsis</Emphasis> (Proteaceae) from Bahia,Brazil

Recent collections from Bahia, Brazil included a new species of Panopsis from the Atlantic rainforest. So far it is only known with fruits, which are much larger than in most species of the genus. Panopsis magnifructa is described and compared to other species in the genus. It is only the second species of the genus known in the State of Bahia, Brazil.     

A new <Emphasis Type="Italic">Dactylella</Emphasis> species from <Emphasis Type="Italic">Orbilia alba</Emphasis>

A new Dactylella species, Dactylella alba was isolated from the ascospores of Orbilia alba collected in Wenshan County, Yunnan Province, China. Conidiophores were either not branched or occasionally branched, bearing divergent sterigmata on the tip with single conidium on each. Conidia were elongated ellipsoids, 1–2 septate, mostly 1 septate.
