HbNST1 is a positive regulator of the lignin accumulation in strawflower bracts
Horticultural Plant Journal, 2023 Strawflower (Helichrysum bracteatum) capitula have papery bracts and thus have the qualities of a naturally dried flower. The involucral bract cells have a secondary cell wall (SCW) of which a crucial component is lignin.

Defense and carnivory: Dual role of bracts in Passiflora foetida [PDF]
, 2016 Members of the genus Passiflora are reported to have evolved modifications which kill insects; they have however never been tested for carnivorous syndrome. The flowers of Passiflora foetida consists of highly reticulate bracts which cover and grow along

Genetic Analysis of the Evolution of Petaloid Bracts in Dogwoods. [PDF]
The genus Cornus is best known for beautiful flowering dogwood trees that have large petaloid bracts. Another group of species within Cornus, the dwarf dogwoods, also bear petaloid bracts, and whether there were one or two origins of petaloid bracts in ...

<i>Primula octopoda</i>, a Stoloniferous New Species From Western Sichuan, China. [PDF]
Ecol EvolPrimula octopoda W.B.Ju & Q.Huang, a new species of Primula (Primulaceae) in sect. Aleuritia, is herein described and illustrated from Batang County, Sichuan Province, southwestern China. Morphologically, P. octopoda is most similar to P. stenocalyx, but it can be readily distinguished by its dwarf habit, the presence of stolons 2–7 cm in length ending
