Pterosabiales contains a monotypic family Pterosaviaceae, which includes Japanolirion<\/em> endemic to Japan and Pterosavia<\/em> distributed in East and South Eastern Asia. Japanolirion osense <\/em>forms green leaves and is autotrophic, while Pterosavia<\/em> ssp. are saprophytic. Chloroplast genome of Pterosavia stellaris<\/em> is reduced (Logacheva et al. 2014) but ATP synthase, rbcL<\/em> and some other genes are still retained. The reason why these genes usually function in photosynthesis are retained is unknown but may function in other ways (Krause 2008). rbcL is revealed to function in lipid synthesis (Schwender et al. 2004) and as RNA binding protein (Yosef et al. 2004). No saprophyte genomes were published and such study will give insight on the evolution at the gene level.<\/p>\n

Ridges on an inflorescence stem are connected to flowers. It is unknown why this structure is formed in both structural and adaptive senses. A flower is subtended by a bract and a prophyll. The function of prophyll is unknown.<\/p>\n
