Tocantinia is a monotypic genus of herbaceous perennial bulbous flowering plants in the amaryllis family, Amaryllidaceae, subfamily Amaryllidoideae. The sole species is Tocantinia mira.



Flowers are single, the stigma capitate. Spathe bracts are lanceolate, with a single valve. [3] [4]


Once placed in its own tribe (Tocantinieae) by Ravenna, it is now located in subtribe Hippeastrinae of tribe Hippeastreae. [1] The sole species is Tocantinia mira, which is found in central Brazil (Tocantins State). [2] [5] [3]

Distribution and habitat

Tocantinia mira grows in a dry forest between the rivers Araguaia and Tocantins. [6]

<i>Amaryllis</i> Genus of plants

Amaryllis is the only genus in the subtribe Amaryllidinae. It is a small genus of flowering bulbs, with two species. The better known of the two, Amaryllis belladonna, is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley and Knysna. For many years there was confusion among botanists over the generic names Amaryllis and Hippeastrum, one result of which is that the common name "amaryllis" is mainly used for cultivars of the genus Hippeastrum, widely sold in the winter months for their ability to bloom indoors. Plants of the genus Amaryllis are known as belladonna lily, Jersey lily, naked lady, amarillo, Easter lily in Southern Australia or, in South Africa, March lily due to its propensity to flower around March. This is one of numerous genera with the common name "lily" due to their flower shape and growth habit. However, they are only distantly related to the true lily, Lilium. In the Victorian Language of Flowers, amaryllis means "pride, determination and radiant beauty".

<i>Hippeastrum</i> Genus of flowering plants in the family Amaryllidaceae

Hippeastrum is a genus of about 90 species and over 600 hybrids and cultivars of perennial herbaceous bulbous plants. They generally have large fleshy bulbs and tall broad leaves, generally evergreen, and large red or purple flowers.

<i>Eucharis</i> (plant) Genus of flowering plants

Eucharis is a genus of about 15-20 species of neotropical plants in the Amaryllis family, native to Central America and South America, from Guatemala south to Bolivia. Some species have become naturalized in Mexico, the West Indies, and scattered tropical islands. The English name Amazon lily is sometimes used for all species in the genus, but is particularly used for Eucharis amazonica and Eucharis × grandiflora, which are often confused.

<i>Habranthus</i> Genus of plants

Habranthus (copperlily) is a genus of tender herbaceous flowering bulbs in the subfamily Amaryllidoideae of the family Amaryllidaceae. The genus was first identified by pioneering bulb enthusiast William Herbert in 1824. The species are native to the Americas, from, but several species are naturalized in other parts of the world West Indies, India, South Africa, Mauritius, Colombia, Easter Island, and the southeastern United States.

<i>Rhodophiala</i> Genus of flowering plants

<i>Rhodolirium</i> Genus of flowers

Rhodolirium is a small South American genus in the tribe Hippeastreae of the family Amaryllidaceae. Although originally described by Philippi in 1858 it has long remained buried in other taxa, principally Hippeastrum and more recently Rhodophiala. Only in recent years has it been rehabilitated.

Griffineae Tribe of flowering plants

The tribe Griffineae includes 2 genera with 22 species from South America which are actually endemic to Brazil. A typical character of the representatives of the tribe are the flowers - They are with blue or lilac color collected into an umbel. Only the members of this tribe and the genus Lycoris are able to form flowers with such color in the whole family Amaryllidaceae. The plants in this group are typical perennial flowers which are producing bulbs. The leaves are green, with elliptical form in the most of the cases but in some members as in Worsleya they are sword-shaped.

Amaryllidaceae A family of flowering plants comprising members popular for horticulture and vegetable production

The Amaryllidaceae are a family of herbaceous, mainly perennial and bulbous flowering plants in the monocot order Asparagales. The family takes its name from the genus Amaryllis and is commonly known as the amaryllis family. The leaves are usually linear, and the flowers are usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae).

Hippeastreae Tribe of flowering plants

Hippeastreae is a tribe of plants belonging to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae). Species in this tribe are distributed in South America. Flowers are large and showy, zygomorphic, with the stamens in varying lengths, inflorescence bracts are often fused basally. The seeds are flattened, winged or D-shaped. Reported basic chromosome numbers are x= 8-13, 17, and higher. All the species in this tribe present a remarkable aesthetic interest and horticultural value.

Of the three tribes of genera that make up the subfamily Allioideae, Gilliesieae is the largest and most variable. The tribe was divided into two tribes in 2014, Gilliesiae s.s. and Leucocoryneae, based on differences in floral symmetry and septal nectaries.
