Alcea Alcea Alcea is a genus of about 60 species of flowering plants in the mallow family Malvaceae, commonly known as the hollyhocks. They are native to Asia and Europe. The single species of hollyhock from the Western Hemisphere, the streambank wild hollyhock, belongs to a different genus. Hollyhocks are annual, biennial, or perennial plants usually taking an erect, unbranched form. The herbage usually has a coating of star-shaped hairs. The leaf blades are often lobed or toothed, and are borne on long petioles. The flowers may be solitary or arranged in fascicles or racemes. The notched petals are usually over
Armatimonas rosea width and 2.4–3.2 µm in length. Neither spores nor flagella were observed. When investigated in R2A media, cultures of "A. rosea" were observed to be aerobic and chemoheterotrophic with no evidence of growth under anaerobic conditions. It is negative for the following tests: nitrate respiration, fermentative growth, catalase, and cytochrome oxidase. Armatimonas rosea Armatimonas rosea is a Gram-negative bacterium and also the first species to be characterized within the phylum Armatimonadetes. The Armatimonadetes were previously known as candidate phylum OP10. OP10 was composed solely of environmental 16S rRNA gene clone sequences prior to "A. rosea's" discovery. "A. rosea" was originally
