Steric Constraints as a Global Regulation of Growing Leaf Shape [PDF]

open access: yes, 2009
Shape is one of the important characteristics for the structures observed in living organisms. Whereas biologists have proposed models where the shape is controlled on a molecular level [1], physicists, following Turing [2] and d'Arcy Thomson [3], have ...

Floral Structure of Kirkia (Kirkiaceae) and its Position in Sapindales [PDF]

open access: yesAnnals of Botany, 2008
The monogeneric Kirkiaceae (Sapindales) were formerly placed as Kirkioideae in Simaroubaceae. However, recent molecular phylogenetic studies indicate that they are not in Simaroubaceae and they appear to be sister to the clade of Anacardiaceae plus Burseraceae. Such affinity was never considered or discussed since the first description of Kirkia.

Integrated Pest Management of Longan (Sapindales: Sapindaceae) in Vietnam [PDF]

open access: yesJournal of Integrated Pest Management, 2019
AbstractThis paper describes the current state of pests and diseases of longan (Dimocarpus longan Lour.) and their management in Vietnam. Longan is the third most cultivated fruit crop and second major fruit crop exported from Vietnam. Brief descriptions of arthropod pests Eriophyes dimocarpi Kuang (Acari: Eriophyidae), Conogethes punctiferalis Guenée (

Important Medicinal and Food Taxa (Orders and Families) in Kenya, Based on Three Quantitative Approaches

open access: yesPlants, 2023
Globally, food and medicinal plants have been documented, but their use patterns are poorly understood. Useful plants are non-random subsets of flora, prioritizing certain taxa.

Osmophores and floral fragrance in Anacardium humile and Mangifera indica (Anacardiaceae): an overlooked secretory structure in Sapindales [PDF]

open access: yes, 2018
Background and aims: Flowers of Anacardiaceae and other Sapindales typically produce nectar, but scent, often associated with a reward for pollinators, has surprisingly been mentioned only rarely for members of the family and order.

Fruit Anatomy of the Canarieae (Burseraceae)

open access: yesPlants, 2022
Fruits historically have been the key character for delimitation of tribes in the Burseraceae. However, fruit structure is incompletely known within the family, thus the importance of this character is unclear.

Rooting and dating maples (Acer) with an uncorrelated-rates molecular clock [PDF]

open access: yes, 2008
Simulations suggest that molecular clock analyses can correctly identify the root of a tree even when the clock assumption is severely violated. Clock-based rooting of phylogenies may be particularly useful when outgroup rooting is problematic.
