Sesamum is a genus of approximately 20 species in the flowering plant family Pedaliaceae.
 The plants are annual or perennial herbs with edible seeds.
 The best-known member of the genus is sesame, "Sesamum indicum" (syn.
 "Sesamum orientale"), the source of sesame seeds.
 The species are primarily African, with some species occurring in India, Sri Lanka, and China.
 The origin of "S. indicum" is uncertain as it is widely cultivated and naturalized in tropical regions.
 The genus is closely related to the strictly African genus "Ceratotheca" and is itself probably African in origin.
Herbchronology is the analysis of annual growth rings (or simply annual rings) in the secondary root xylem of perennial herbaceous plants.
 While leaves and stems of perennial herbs die down at the end of the growing season the root often persists for many years or even the entire life.
 Perennial herb species belonging to the dicotyledon group (also known as perennial forbs) are characterized by secondary growth, which shows as a new growth ring added each year to persistent roots.
 About two thirds of all perennial dicotyledonous herb species with a persistent root that grow in the strongly seasonal zone of the northern hemisphere show at least fairly clear annual growth rings.
Platysace is a genus of woody perennial herbs and subshrubs in the family Apiaceae.
 The genus is endemic to Australia.
Celmisia (New Zealand aster or New Zealand daisy) is a genus of perennial herbs or subshrubs, in the sunflower family.
 Most of the species are endemic to New Zealand; several others are endemic to Australia.
Mimetes is a genus of plants in the large family Proteaceae.
 This genus, as with other proteas, is popular with nectivorous birds such as the Cape sugarbird and several sunbird species.
Ziziphora is a genus of annual or perennial herbs or subshrubs in the Lamiaceae family.
 "Ziziphora" has aromatic leaves; it is open and often xeric habitats in Southern and Eastern Europe, North-West Africa and Asia to the Himalayas and Altai mountains.
Buglossoides is a genus consisting of 15 species of annual or perennial herbs, native to Europe and Asia.
 They grow naturally in habitats ranging from sunny scrub to rocky slopes and woodland areas.
 These plants are covered in fine bristles or hairs.
 The stems are upright or sprawling, branched or unbranched, with simple oval to lance-shaped leaves.
 The small funnel-shaped flowers have flaring lobes and are usually blue or white.
 Perennial species that are rhizomatous can become invasive and difficult where conditions are suitable.
Shortia is a small genus of subshrubs or perennial herbs in the family Diapensiaceae.
 There are five species, four in Asia and one in the Appalachian Mountains of eastern North America.
 They are found in mountainous areas, generally from 1000 – elevation.
 All have restricted ranges and are generally considered rare.
 Three of the species, "S. galacifolia", "S. soldanelloides", and "S. uniflora" are often cultivated.
 The genus was by Asa Gray named after botanist Charles Wilkins Short.
 In Gray's diary entry for April 8, 1839, he named the genus after Charles Wilkins Short because the plant was native to America in a region close to where Short lived, which was Kentucky.
 Short and Gray never met but they corresponded with one another frequently.
 Short never saw a live nor dried specimen of his namesake genus.
Gillenia (syn.
 "Porteranthus") is a genus of two species of perennial herbs in the Rosaceae family.
 Common names for plants in this genus include: Bowman's root, Indian-physic, American ipecac.
 This genus is endemic to dry open woods with acidic soils in eastern North America.
 Both plants are subshrubs with exposed semi-woody branches and serrated leaves; the larger lower leaves are divided into palmately arranged leaflets.
 Plants bloom in May, June, or July; blooms are composed of five slender white petals which are loosely arranged and typically appear slightly twisted and limp as if they were wilted.
 The flowers mature into small capsules.
 These plants are often planted as ornamentals and used in herbal medicine.
Haploesthes is a North American genus of flowering plants in the daisy family.
 It grows in Mexico and in the southwestern United States.
 They are perennial herbs or subshrubs with yellow flower heads.

Question: Are both Mimetes and Shortia a genus of subshrubs or perennial herbs?
Answer: no
