As a result of ongoing studies of the Rubiaceae of Gabon, the new species Colletoecema gabonensis is here described and illustrated. It is endemic to Gabon, where it is the only species of the genus, and is so far only known from three collections from the Ogooué-Lolo and Ngounié provinces. The new species is morphologically intermediate between its two congeners, C. dewevrei (from Cameroon, Central...
Stylogyne araujoana, a new endemic species from the Atlantic Forest Region of Rio de Janeiro State, Brazil is described, illustrated, and mapped. Its relationships with Stylogyne pauciflora and Stylogyne sordida are discussed, and comments concerning the taxonomy, ecology, and conservation status are provided. Micromorphological leaf characters are illustrated and discussed.
Two new species of Erythroxylum from the Amotape-Huancabamba region are described and illustrated. Erythroxylum dillonii occurs in the arid zones of northern Peru, and Erythroxylum gentryi is known only from the Ecuadorian side of Cordillera del Condor.

Alansmia, a new genus of grammitid ferns is described and combinations are made for the 26 species known to belong to it. Alansmia is supported by five morphological synapomorphies: setae present on the rhizomes, cells of the rhizome scales turgid, both surfaces of the rhizome scales ciliate, laminae membranaceous, and sporangial capsules setose. Other diagnostic characters include pendent fronds...

Two species of Leandra that occur in low montane and montane rain forests in the state of Espírito Santo, Eastern Brazil, are described and illustrated here. Leandra magnipetala can be recognized by the pedicellate flowers, costate hypanthia, and large, broadly lanceolate petals. Leandra triantha can be recognized by the apical, short-peduncled triads, diads or solitary flowers and by the granulose-glandulose,...
Badiera subrhombifolia is newly described from Hispaniola, where it co-occurs with B. fuertesii and B. penaea. Badiera subrhombifolia lacks the long peduncle of the former species and the scabrous leaves of the latter; it is also often distinguishable by subrhomboid, triplinerved leaves. This new species is a near endemic to high montane forests of the “south island” of Hispaniola, i.e., the Massif...
Two new species of Borreria are described: the first, Borreria johnwoodii from the Campo Cerrado area of the Noel Kempff Mercado National Park; the second, Borreria siberiana from the cloud forest of the Yungas, between 2600 and 3100 m above sea level. Declieuxia cordigera is recorded for the first time from Bolivia. Borreria nectarifera is shown to be synonymous with B. eryngioides var. affinis.

In northern Việt Nam the felling of Cupressus for wood and incense has resulted in the decimation of wild cypress populations. Ever since specimens of Cupressus from Việt Nam were first sent to Paris in 1905, they have been inappropriately referred to a variety of names including Cupressus funebris, Cu. torulosa, and synonyms of Callitropsis lusitanica. This taxonomic disarray was somewhat ameliorated...
