Phylogenetic evidence reshapes the taxonomy of Cacao and its allies (Theobroma and Herrania; Malvaceae, Byttnerioideae).
(Malvaceae, Byttnerioideae), the cacao genus, has a taxonomic history spanning over two centuries. Currently, it comprises 23 species of trees from lowland forests from the Tropical Americas. , a closely related genus described later, includes 17 additional species commonly referred to as “wild cacaos.” Phylogenetic relationships and morphological circumscriptions between... -

A new classification system and taxonomic synopsis for Malpighiaceae (Malpighiales, Rosids) based on molecular phylogenetics, morphology, palynology, and chemistry.
Malpighiaceae has undergone unprecedented changes in its traditional classification in the past two decades due to several phylogenetic studies shedding light on the non-monophyly of all subfamilies and most tribes and genera. Even though morphological characters were used to reconstruct the last molecular generic phylogeny of Malpighiaceae, a new classification... -

Marsh-orchids of Canada: long-standing mysteries partially solved.
Between 1959 and 1988, three populations of purple-flowered terrestrial orchids attributable to subgenus were discovered in Canada. The populations at Timmins, Ontario, and St John's, Newfoundland were strongly marked on both flowers and leaves, in contrast with the anthocyanin-deficient population at Tilt Cove, Newfoundland. All three populations have since experienced... -

Tarenna thorelii (Rubiaceae), a new record for Thailand.
Tarenna thorelii is reported as a new record for Thailand based on collections from Khon Kaen and Roi Et Provinces. A morphological description based on Thai specimens, distribution, ecological information, conservation status, and short notes on the species as well as an illustration are provided. In addition, a lectotype for...Wirot, Wirot ; Chantaranothai, Pranom

Clusia salicifolia (Clusiaceae), a new hemiepiphyte species from Costa Rica and Panama.
We describe and illustrate (Clusiaceae) a new species from Central America. This new species is different to all related species for its hemiepiphytic habit, narrow leaves with acute to acuminate apex, reticulate resin canals, staminate flowers with quadrangular androecium with 30 – 47 free stamens, and pistillate flowers with 4...Wodcke, Emma A. ; Luján, Manuel ; Hammel, Barry

Pollen morphology of the Sapotaceae from Thailand and its taxonomic implications.
The external pollen morphology of the family Sapotaceae in Thailand was examined using the acetolysis method to determine its taxonomic significance. Pollen of 39 specimens belonging to 32 species was investigated by means of light and scanning electron microscopy. Pollen grains are found to be monads, isopolar, colporate, lalongate, and...Kunasit, Pongsakorn ; Chantaranothai, Pranom

New species and a revision of the genus Peperomia (Piperaceae) in Thailand.
We update the descriptions of seventeen native species of Peperomia in Thailand, including a new species, P. ranongensis, and a detailed morphological description for the uncommon species P. kotana based on Thai specimens. We provide a generic description, a key to all the species and provide lectotypifications for P. bavina,...
