They may look like extra-floral nectaries, but the galls in some South American trees are evidence of wasps calling in some help to look after their young.
Below-ground bud bank along a climatic gradient in a temperate steppe

New insights into the formation of silica aggregates in sorghum roots
Even though silica and lignin can provide comparable stiffness, they cannot be considered as structural equivalents due to contrasting hydrophobicity.
Polyphyly of Arundinoideae (Poaceae) and awn evolution in the grasses
This study answers one of the last remaining big questions in grass taxonomy while highlighting examples of convergent evolution in an ecologically important trait, the hygroscopic, twisted geniculate awn.
Stolon-tuber system and phylogeny of orchid-like bladderworts (Lentibulariaceae)
