Thunbergia bicolor, also known as the bicolor clockvine, [1] is a species of flowering plant within the family Acanthaceae. [2]
The leaves of Thunbergia bicolor are paired at a node and borne opposite to each other. They are oval to triangular in shape, with a pointed tip and a base that can be either truncate or rounded. The leaves are palmately veined and the veins radiate out from a central point like the fingers of a hand. The leaf margins are crenate, exhibiting shallow rounded teeth along the edges. [3]
The flowers of this Thunbergia bicolor are borne in hanging clusters known as axillary pendent racemes. These clusters are positioned in the leaf axils, where the leaf meets the stem. The flowers are accompanied by conspicuous bracts that are roughly 2-2.5 cm in diameter. These bracts have a cordate-orbicular shape, with the upper half displaying an orange-red coloration while the lower half is pale yellow. [3]
The calyx, which forms the outermost part of the flower, is either an entire (smooth) ring or slightly crenulate (with slight scalloping). The corolla, the inner part of the flower, is bluish and eye-catching. It consists of a cylindrical or bulging tube that curves, while the corolla limb is oblique in shape. There are five lobes in the corolla, which are twisted to the left while in the bud stage. [3]
Stamens, the male reproductive parts of the flower, are present in sets of four and are didynamous, meaning they occur in two pairs of different lengths. These stamens are inserted near the base of the corolla tube. Each stamen has anthers that are glabrous and divided into two cells, with each cell featuring a long spur. The ovary of the flower is two-celled, and each cell contains two ovules. [3]
After successful pollination and fertilization, the flower develops into a capsule as the fruit. The capsule has a globose shape at the lower part and abruptly narrows into a beak resembling a sword. The beak is devoid of seeds. Within each cell of the capsule, there are two seeds, and these seeds are globose in shape. Flowering and fruiting occurs between the months of November and January. [3]
Thunbergia bicolor is endemic to Southwest India, [4] where it can be found growing in the South Western Ghats montane rain forests. [3]
Calyceraceae is a plant family in the order Asterales. The natural distribution of the about sixty species belonging to this family is restricted to the southern half of South America. The species of the family resemble both the family Asteraceae and the Dipsacaceae.
This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology.
Ceratolobus was a dioecious genus of flowering plants in the palm family found in Southeast Asia, commonly called rotan. Its species are now included within the genus Calamus. They were only differentiated from Calamus and close relatives like Korthalsia by leaf sheath appendages or inflorescence variations. The Greek genus name combines "horn" and "capsule".
Plectocomiopsis is a dioecious genus of flowering plant in the palm family found in Indochina, Malaysia, Borneo and Sumatra. Hapaxanthic and armed with spines, they are a climbing rattan, closely related to the Myrialepis palms. The name is Greek for "similar to Plectocomia", another close relative.
Calamus dumetosus, synonym Retispatha dumetosa, is a species of flowering plant in the palm family endemic to Borneo, where it is rare and known as wi tebu bruang or 'the bear's sugar cane'. The specific epithet dumetosus means 'bushy'. As Retispatha dumetosa it was the only species in the genus Retispatha. While classified with other rattans, it retains only superficial climbing organs; it sprawls and leans but is not a true climber.
This glossary of botanical terms is a list of definitions of terms and concepts relevant to botany and plants in general. Terms of plant morphology are included here as well as at the more specific Glossary of plant morphology and Glossary of leaf morphology.
