More than symbioses : orchid ecology ; with examples from the Sydney Region [PDF]

open access: yes, 2013
The Orchidaceae are one of the largest and most diverse families of flowering plants. Orchids grow as terrestrial, lithophytic, epiphytic or climbing herbs but most orchids native to the Sydney Region can be placed in one of two categories.

A new combination and typification of Pouzolzia peteri Friis (Urticaceae)

open access: yesNordic Journal of Botany, EarlyView.
Pouzolzia peteri, a lesser‐known species from the African continent, is currently classified as a member of the genus Pouzolzia. However, based on the morphological characteristics of its male flowers and leaf venation, its transfer to the genus Gonostegia is proposed.

Begonia chunxiuensis, a new species of Begonia sect. Platycentrum (Begoniaceae) from Guangxi, China

open access: yesNordic Journal of Botany, EarlyView.
Begonia chunxiuensis, a new species from Guangxi of China, is described and illustrated. It is morphologically similar to B. sinovietnamica and B. aurora, but differs from them by its narrowly triangular stipules, leaf blade that is adaxially green, dark green to viridian, pinkish‐white to white villous, but abaxially light green with red veins, red to

Pollen on stigmas as proxies of pollinator competition and facilitation: complexities, caveats, and future directions.

open access: yesAnnals of Botany, 2020
BACKGROUND Pollen transfer via animals is necessary for reproduction by ~80% of flowering plants, and most of these plants live in multispecies communities where they can share pollinators.

Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant Veratrum grandiflorum

open access: yesNordic Journal of Botany, EarlyView.
Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...

Terniopsis chanthaburiensis (Podostemaceae), a new record for China and its complete plastid genome

open access: yesNordic Journal of Botany, EarlyView.
The genus Terniopsis consists of plants that have not been thoroughly studied, with many species remaining taxonomically unresolved. In this study, Terniopsis chanthaburiensis is reported as a new record of China based on morphological traits. Then, we assembled and annotated its chloroplast genome based on genome skimming data.

Reinstatement of the name Anisochilus eriocephalus Benth. (Lamiaceae) supported by micromorphological and molecular data

open access: yesNordic Journal of Botany, EarlyView.
In 2019, A. J. Paton et al. proposed a new taxonomic combination, transferring Anisochilus carnosus (L.f.) Wall. ex Benth. to Coleus strobilifer (Benth.) A.J.Paton, and including Anisochilus eriocephalus Benth. within this broader circumscription.

Developmental onset of reproductive barriers and associated proteome changes in stigma/styles of Solanum pennellii

open access: yesJournal of Experimental Botany, 2012
Although self-incompatibility (SI) in plants has been studied extensively, far less is known about interspecific reproductive barriers. One interspecific barrier, known as unilateral incongruity or incompatibility (UI), occurs when species display ...
