The complete chloroplast genome of the lipstick tree, (Bixaceae).

is a small tree known for its red, oil-soluble pigment contained in the seed coat that is used as a natural dye and food coloring. In this study, we assembled and characterized the complete chloroplast genome of as a resource for future genetic studies. With a total length of 159,825 bp, the chloroplast genome comprised of a large single-copy (LSC) region of 89,476 bp, a small single-copy (SSC) region of 19,617 bp, and two inverted repeat (IR) regions of 25,356 bp each.

Revision of series Gravesiana (Adiantum L.) based on morphological characteristics, spores and phylogenetic analyses.

Since the adoption of some ambiguous and quantitative characters in Flora Republicae Popularis Sinicae 3(1), species identifications of the series Gravesiana have been in disarray, requiring clarification. Two hundred and fifty-nine individuals from 47 different populations were collected for the estimation of morphological characters and phylogenetic analyses. Spores of 26 populations were observed through scanning electron microscope.
