Abstract:
Rayleya nov. gen. (Sterculiaceae - Byttnerieae) is proposed with one species R. bahiensis from Bahía, Brazil. The new genus is characterized by its 2-celled anthers as in Byttneria, by the presence of androgynophore, the claw shape of the petals, and the staminodes as in sorne species of Ayenia, and by a peculiar gland at the bottom of the petaIs. Two figures and a key are given.

Abstract:
Byttneria (Malvaceae, Byttnerioideae) is a Pantropical genus known for its variable growth forms—ranging from shrubs to lianas—and complex floral structures. In this study, we describe a new species, Byttneria filifolia Gerace & Colli-Silva, from B. sect. Crassipetala, found in the Eastern Amazon rainforest of Brazil, specifically in Pará, and Mato Grosso states. Byttneria filifolia is distinguished from its relatives by its filiform leaves, as well as by the multiaperturate leaf nectary, growth form, leaf shape, and petal morphology. This study contributes to our comprehension of morpholo

This study aims to promote the wild food plants consumed in households in the city of Man. To achieve this objective, an ethnobotanical survey was conducted in 90 households distributed in three districts of the city of Man, in order to inventory the wild plants that are consumed there. The survey was completed by the mineral and phytochemical analysis of two plants selected following the survey carried out in the city. The results obtained make it possible to identify 34 plant species, 27 of which have been identified, divided into 21 botanical families. The majority of the plants mentioned a

Abstract:
The rotated-lamina syndrome is a condition most commonly found in dorsiventral shoots with distichous phyllotaxis. Typically, young laminae in bud appear to be rotated to face towards the upper side of the shoot. The syndrome arises by asymmetrical growth from leaf primordia that initially face the shoot apex in approximately the normal way. It was previously described in Tilia. Further genera of Tiliaceae and the closely related Sterculiaceae were examined for the presence of the syndrome. Altogether it was found in 9 genera of the 30 examined. The syndrome is well developed in representative
