Context paragraphs:
Handroanthus albus: Handroanthus albus, the Golden Trumpet Tree, is a tree with yellow flowers native to the Cerrado (tropical savannas) of Brazil, where it is known as "ipê-amarelo-da-serra" .

Acleisanthes: Acleisanthes is a genus of flowering plants in the "Bougainvillea" family, Nyctaginaceae.  There are currently 16 species.  The generic name is derived from the Greek words ακλειοτος ("akleistos"), meaning "not closed," and ανθος ("anthos"), meaning "flower."  Plants of this genus are known commonly as trumpets due to the elongated, open-ended shape of their flowers.  These are arid-adapted perennials with thick taproots which are usually compact and low to the ground or slightly ascending.  An individual plant may have cleistogamous (unopening and self-pollinating) flowers as well as opening flowers which are usually nocturnal as a water-saving adaptation and are pollinated by night-flying or crepuscular insects such as hawkmoths.  Flowers are usually white, sometimes yellow.  These plants are native to the Chihuahuan and Sonoran Deserts of Mexico and the United States.

Rhododendron fastigiatum: Rhododendron fastigiatum is a dwarf lepidote rhododendron species with purple flowers native to Yunnan, China.  Cultivars include 'Best Dark Purple’.

Dicentra formosa: Dicentra formosa (western, wild or Pacific bleeding heart) is a flowering plant with fern-like leaves and an inflorescence of drooping pink, purple, yellow or cream flowers native to the Pacific Coast of North America.

Dicentra eximia: Dicentra eximia (wild or fringed bleeding-heart, turkey-corn) is a flowering plant with fernlike leaves and oddly shaped flowers native to the Appalachian Mountains.  It is similar to the Pacific bleeding-heart ("Dicentra formosa"), which grows on the Pacific Coast.

Rosa hemisphaerica: Rosa hemisphaerica, also known as the sulphur rose, is a rose species with pale yellow flowers native to western Asia.  The wild form, known as "Rosa raphinii", has single flowers with five petals.  A double-flowered form was one of the first yellow roses introduced to European gardens; John Bellenden Ker Gawler stated in 1815 that the species had been cultivated in England for nearly 200 years.  The scent of the flowers has been described as unpleasant.

Azorella: Azorella is a genus of about 70 species of flowering plants in the family Apiaceae, native to South America, New Zealand and the islands of the Southern Ocean.

Cyrillaceae: The Cyrillaceae are a small family of flowering plants in the order Ericales, native to warm temperate to tropical regions of the Americas.  The family comprises two genera, "Cliftonia" and "Cyrilla", each containing a single species, "Cliftonia monophylla" and "Cyrilla racemiflora".  However, additional species of "Cyrilla" are now often recognized and the genus is in need of taxonomic revision.

Cyrilla: Cyrilla racemiflora, the sole species in the genus Cyrilla, is a flowering plant in the family Cyrillaceae, native to warm temperate to tropical regions of the Americas, from the southeastern United States (coastal areas from southeastern Texas east to southeastern Virginia), south through the Caribbean, Mexico (Oaxaca only) and Central America to northern Brazil and Colombia in South America.  Common names include swamp cyrilla, swamp titi, red titi,black titi, white titi, leatherwood, ironwood, he huckleberry, and myrtle.
