Are Mimosa and Sidalcea both genus of plants ?
yes
Title: Mimosa
Passage: Mimosa is a genus of about 400 species of herbs and shrubs, in the mimosoid clade of the legume family Fabaceae.  The generic name is derived from the Greek word μιμος ("mimos"), an "actor" or "mime," and the feminine suffix –"osa", "resembling", suggesting its 'sensitive leaves' which seem to 'mimic conscious life'.
Title: Chundikuli
Passage: Chundikuli (Tamil: சுண்டிக்குளி , "Cuṇṭikkuḷi " ; Sinhalese: චුන්දිකුලි "Cundikuli") is a suburb of the city of Jaffna in northern Sri Lanka.  Chundikuli means "the pond of the cunti plant" in Tamil and is derived from the Tamil words "cunti" (several aquatic plants from the mimosa genus) and "kuli" (pond).  The suburb is divided into two village officer divisions (Chundikuli North and Chundikuli South) whose combined population was 3,618 at the 2012 census.
Title: Desmanthus
Passage: Desmanthus is a genus of flowering plants in the mimosoid clade of the subfamily Caesalpinioideae of the pea family, Fabaceae.  The name is derived from the Greek words δεσμός ("desmos"), meaning "bundle", and ἄνθος ("anthos"), meaning "flower".  It contains about 24 species of herbs and shrubs that are sometimes described as being suffruiticose and have bipinnate leaves.  "Desmanthus" is closely related to "Leucaena" and in appearance is similar to "Neptunia".  Like "Mimosa" and "Neptunia", "Desmanthus" species fold their leaves in the evening.  They are native to Mexico and North, Central and South America.  Members of the genus are commonly known as bundleflowers.  Donkey beans is another common name and originated in Central America, where "Desmanthus" species are highly regarded as fodder for these domestic draught animals.
Title: Sidalcea
Passage: Sidalcea is a genus (approx. 25 species) of the botanical family Malvaceae.  It contains several species of flower known generally as checkerblooms or checkermallows, or prairie mallows in the United Kingdom.  They can be annuals or perennials, some rhizomatous.
