TL;DR: New light is shed on the genetic mechanisms underpinning key orchid innovations, including the development of the labellum and gynostemium, pollinia, and seeds without endosperm, as well as the evolution of epiphytism; reveals relationships between the Orchidaceae subfamilies; and helps clarify the evolutionary history of orchids within the angiosperms.

TL;DR: In this paper , the complete plastid genomes of Hellenia species were obtained and the monophyly of the genus was tested through four different datasets in this study, and two major clades were recovered.

TL;DR: A new species, Fordiophyton tereticaule, from China, is described and illustrated here based on morphological and molecular evidence that is morphologically similar to F. faberi but differs by the terete stems, densely puberulous petioles, and elliptic leaf blades.

TL;DR: A new species of Sporoxeia (Melastomataceae), S. vietnamensis, was described from northern Vietnam as mentioned in this paper , which is morphologically similar to S. blastifolia in having obtusely quadrangular stems, slightly unequal leaf blades with cuneate bases, and two secondary veins on each side of midvein.

TL;DR: This new species is morphologically similar to B. malipoensis in having tomentose stems and leaves, cordate leaf blades in unequal pairs, an umbellate inflorescence, and undulate petals with an unguiculate base and retuse apex, but differs by having bullates leaf blades, white hypanthia and elliptic calyx lobes.
