Flowering plant clade of flowering plants (in APG I-III)

The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,164 known genera and c. 369,000 known species. Like gymnosperms, angiosperms are seed-producing plants. However, they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion and sperma ("seed").

Gesneriaceae family of plants

Gesneriaceae is a family of flowering plants consisting of about 152 genera and ca. 3,540 species in the Old World and New World tropics and subtropics, with a very small number extending to temperate areas. Many species have colorful and showy flowers and are cultivated as ornamental plants.

Description

The petioles of this species are puberulent and grow to approximately 4 cm. The leaves are sparsely pubescent, and have a broadly ovate to orbicular or broadly elliptic shape. They grow to about 0.5 to 4.0 cm x 0.4 to 0.3 cm. [2]

Petiole (botany)

In botany, the petiole is the stalk that attaches the leaf blade to the stem. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves lacking a petiole are called sessile or epetiolate.
