#Malvaceae
- Abutilon — A genus of herbaceous or shrubby plants in the family Malvaceae, native to tropical and subtropical regions, widely cultivated in horticulture as an ornamental indoor or garden plant. Popularly known as the 'parlor maple' due to the lobed shape of its leaves, the plant is highly esteemed for its spectacular, pendulous, bell-shaped or Chinese lantern-like flowers, colored in bright shades of yellow, red, pink, or orange.
- Abutilon avicennae — The synonymous scientific designation for *Abutilon theophrasti*, popularly known in Romanian as 'teiușor' or 'crucea-pământului'. This annual herbaceous plant in the Malvaceae family, native to Asia, is recognized in modern agronomy as a severe invasive weed in row crops (corn, sunflower, soy), characterized by large, velvety, heart-shaped leaves and rigid, decorative, star-like seed capsules.
- Abutilon darwinii — A species of ornamental shrub in the Malvaceae family, native to the tropical forests of Brazil, characterized by densely pubescent, palmate-lobed leaves and large, bell-shaped, pinkish-orange flowers highlighted by spectacular reddish veins. This species plays a historical and fundamental role in global horticulture, being one of the primary genetic parents used in creating most decorative *Abutilon* hybrids grown today in greenhouses and apartments.
- Abutilon megapotamicum — A species of semi-scandent or trailing shrub in the Malvaceae family, native to Brazil, Argentina, and Uruguay, remarkable for its long, flexible, arching branches. It is widely cultivated for ornamental purposes due to its unique and spectacular flowers, hanging from thin pedruncles, which feature a swollen, bright red calyx from which contrasting yellow petals and prominent purple stamens emerge, a look reminiscent of Chinese lanterns.
- Abutilon theophrasti — The standard scientific name for velvetleaf, an annual herbaceous plant in the Malvaceae family, native to Southern Asia and widely naturalized across Europe and the Americas. Agronomically, it is considered an extremely harmful and highly competitive weed for agricultural row crops, remarkable for its robust stem covered in velvety hairs, large heart-shaped leaves, and characteristic semicircular capsule fruits made of radially arranged chambers.
- Abutilon vitifolium — The synonymous scientific designation for *Corynabutilon vitifolium*, a species of large shrub or small tree in the Malvaceae family, native to the temperate rainforests of Chile. This unique plant is widely cultivated globally in botanical and landscape gardens due to its large, soft-haired, palmate-lobed leaves that resemble vine leaves, and for its spectacular, wide-open, cup-shaped flowers colored in delicate shades of pale blue, lavender, or golden-white.
- Abutilon x hybridum — The collective designation assigned to a vast and complex group of artificial ornamental hybrids in the Malvaceae family, obtained through the selective crossbreeding of several species native to South America (such as *Abutilon darwinii* and *Abutilon striatum*). These plants, universally known as 'parlor maples', are among the most popular potted plants globally, highly valued for their continuous blooming, lush foliage, and rich color palette of bell-shaped corollas (white, yellow, pink, orange, red).
- Adelphous — A specialized term used to describe a flower or plant whose stamens are fused or united by their filaments, forming one or more distinct bundles. As a noun, it defines any plant organ or floral structure exhibiting this particular anatomical feature of fusion, commonly found in families such as Malvaceae.
- Althaea — Scientific name or archaic Romanian variant for the marshmallow plant (Althaea), especially the common marshmallow; an herbaceous plant of the Malvaceae family, recognized for its emollient and medicinal properties, used since ancient times in treating respiratory conditions.
- Althaea — A genus of perennial herbaceous plants in the family Malvaceae, native to Europe, North Africa, and Asia; includes well-known species such as the common marshmallow (Althaea officinalis), extensively cultivated for ornamental and pharmaceutical purposes due to its rich mucilage content with emollient and anti-inflammatory effects.
- Althaea cannabina — A species of perennial herbaceous plant in the genus Althaea, family Malvaceae, native to southern Europe and Central Asia; it is recognized by its deeply palmate-lobed leaves, similar to those of hemp, and its delicate pinkish-purple flowers carried on tall, slender stems.
- Althaea ficifolia — A species of biennial or perennial herbaceous plant in the family Malvaceae (often taxonomically classified as Alcea ficifolia), native to Siberia and Asia Minor; it is characterized by palmate-lobed leaves reminding of fig leaves and tall stems with large, decorative flowers in warm shades of yellow, cream, or copper.
- Althaea rosea — A popular species of biennial or perennial herbaceous plant in the family Malvaceae (classified in modern taxonomy as Alcea rosea), commonly known as hollyhock; it is native to Asia and extensively cultivated worldwide for its high ornamental value, featuring very tall stems and large, spectacular flowers in shades ranging from white and pink to deep red or dark purple.
