Mabberley's plant-book: a portable dictionary of plants, their classifications and uses.

TL;DR: In this paper, the dictionary is used as a reference for the use of nouns and verbs in this book. But the dictionary can be used for many purposes. But it is not suitable for children's reading.

Seed size and shape predict persistence in soil

TL;DR: A rapid, simple method for predicting seed persistence in the soil, tested on a range of British, mostly herbaceous, species, finds all diaspores within an area of the graph defined by a maximum weight and variance are persistent in the soils.
Journal ArticleDOI

The strigolactone germination stimulants of the plant-parasitic Striga and Orobanche spp. are derived from the carotenoid pathway

TL;DR: For these three host and two parasitic plant species, the strigolactone germination stimulants are derived from the carotenoid pathway, and this finding is discussed as an explanation for some phenomena that have been observed for the host-parasitic plant interaction.
Journal ArticleDOI

Hybridization and the Extinction of Rare Plant Species

TL;DR: It is suggested that hybridization is an increasing threat to rare species because ecological barriers are being disrupted by human activities and the negative consequences of hybridization are unlikely to be compensated for by immigration from conspecific populations.
Journal ArticleDOI

Predicting the identity and fate of plant invaders: emergent and emerging approaches.

TL;DR: In this article, a conceptually diverse array of correlative and experimental approaches have been developed to predict the identity and fate of future invaders, including lists of species known to be aggressive either in their native range or a new range.
