Pharaxonotha cerradensis, new species (Coleoptera: Erotylidae), is described from Bolivia and Brazil. It belongs in a complex of Mexico Central America that radiated on host cycads the genus Zamia L. (Cycadales: Zamiaceae) associated with boliviana (Brongniart) A. DC. Zamiaceae). cerradensis compared other Reitter.
Zamia brasiliensis Calonje & Segalla, a new subterranean-stemmed species of (Zamiaceae) from Mato Grosso and Rondônia, Brazil, is described illustrated. It compared to two morphologically similar with adjacent geographic distributions: Z. boliviana the Cerrado biome, Amazonian ulei. The shares unarmed petioles but readily distinguishable by its much broader leaflets. has leaflets somewhat resembling those juvenile individuals ulei, latter easily differentiated presence prickles on petiole.
Abstract Brood‐site pollination mutualisms represent extreme levels of reciprocal specialization between plants and insects. Several studies have revealed intimate associations cycads their insect pollinators across different continents. However, the reproductive biology South American is still poorly understood, with limited empirical data available. Here, we investigated plant–pollinator interactions Zamia boliviana (Cycadales, Zamiaceae), which distributed on savanna patches in Brazil...
Zamia multidentata is described and illustrated here as a new species from the Amazon basin, state of Acre, Brazil. The shares morphological similarities with Amazonian Z. hymenophyllidia, urep, to which it compared. combination slender (to 6.2 cm) caulescent stems, strongly serrulate elliptic leaflets long acuminate tips pronounced adaxially raised longitudinal crease, well seed strobili peduncles (15 cm +) flat megasporophylls distinguish all other known in genus.
Abstract Dioecy, a character common to all cycads, requires obligatory outcrossing. The absence of potential reproductive mates the opposite sex renders individuals effectively sterile. Therefore, synchrony is essential for success cycads. Here, we describe phenology, morphology, and lifespan strobili Zamia boliviana (Cycadales, Zamiaceae), an endemic cycad in South America. We examined variation timing maturation between polliniferous ovuliferous two Z. populations. Lifespan was based on...
