Leaf that is triangular, arrowhead shaped, with its basal lobes pointing downward, unlike hastate

Producing long flexible runners or stolons

Covered with scattered short, rigid or harsh hairs that are not erect, often not visible without magnification but evident to touch

Vestite flattened plate-like elements

Climbing; vine-like

Flower stalk that arises directly from the soil

Regarding texture, shriveled, thin, membranous, and dry

1. A taxonomic category intermediate in rank between subgenus and species. The subgenus, if present, is higher than the section, and the rank of series, if present, is below the section. Sections can be further divided into subsections. 2. The cutting a piece of plant tissue in order to see its internal structure

Arranged on, or turned to one side of an axis

A ripened, fertile ovule made up of a protective coat enclosing an embryo and food reserves. In begonias, these are tiny golden barrels ranging in size from .25 to .75mm long. Typically, Begonia species produce between 100-600 seeds per seed capsule

Plant raised from a seed

On an ovary, where the lower part is inferior, but the upper part is free and projects over the perianth. This is rare in the plant kingdom but only found in the Begonia relative Hillebrandia sandwicensis

Caudex forming

A type of Begonia that is probably the most widely grown, in some parts of the country are called “wax type” because of the waxy look to their leaves, grown mostly as bedding plants and treated as annuals, but are really a perennial shrub type in areas that do not freeze

One segment of the calyx; usually green in most plants, found just below or under the petals, but in begonias it is usually attractively colored or white and can be indistinguishable from the petals themselves View Illustration

A wall dividing a cavity or structure into smaller ones

Silky, satin-like sheen; long fine appressed hairs

A leaf margin with sharp saw-like teeth that point forward or slant towards the apex or tip of the leaf

Where each saw-toothed element on a margin, itself has a saw-tooth

A leaf margin with a minutely serrated edge, similar to serrate, but the teeth are smaller

A leaf with base attached directly to the stem or peduncle without a petiole or pedicel; stalkless

Having bristles, bristle-like

Covered with bristles, similar to hispid but less dense

Minutely setose

The geometric outline of a Begonia leaf

A young growing branch or stem

A leaf apex that starts out straight or convex then changes to concave and gradually comes to a point and the angle it makes is greater than 90 degrees. If the angle is less than 60 degrees that it is a long acuminate apex

Begonias characterized by growing upright on branching stems, some have hairy, velvet-like leaf surfaces while others are distinguished by leaf coloring never seen anywhere else. Ex. B. ‘Brevirimosa’, B. venosa, B. lyallii f. Masoalensis, B. polliloensis

A woody plant that produces stems or shoots from the base

Having or being composed of only one thing; scarcely divided or branched at all; an elementary shape

A determinate inflorescence with a simple cluster of three flowers arising from a common peduncle by dichotomous branching

Leaf with one blade per petiole Ex. Peltate: B. ferramica, B. letouzeyi, Basifixed: B. dioica, B. multistaminea

A leaf margin that has a strongly wavy or uneven edge that turns inwards and outwards but is not lobed

The cleft, depression, space, or recess between two lobes or deep incisions of a leaf or petal View Illustration

Occurring or growing at widely spaced intervals; not thick or dense

Like a spatula in shape, with a rounded blade gradually tapering to the base

Subdivision of a genus of a plant family (species is both the singular and plural)

Winding in a continuous and gradually widening (or tightening) curve, either around a central point on a flat plane or about an axis so as to form a cone

Having the shape of scales, scaly; a scale

Rough or scruffy

The male reproductive organ of a flower that produces pollen and consists of an anther and filament View Illustration

Bearing stamens but not pistils, a male flower which does not produce fruit or seeds

Forked or Multiple-branched hairs, each on a short central stalk or sessile; star like

A stalk bearing nodes, supports leaves, buds, flowers, or fruit, and is usually found above ground

How the petiole and stem connect to the blade (leaf), can be straight, oblique or transverse

Lacking functional sex organs or infertile

In the female flower, the top part of the pistil that receives the pollen from the male flower and germinates the pollen prior to fertilization ovule production by the ovary View Illustration

One of a pair of leaf-like appendages found at the base of the petiole. In begonias, they protect a new leaf bud until they split and the new leaf unfolds with its stem (petiole). Caducous fall off early after leaf emerges, Persistent hang on for a while, Marcescent ones dry up but stay in place

A shoot that bends to, or runs along either above or below the ground and takes root giving rise to a new plant at the nodes or tip

A plant that sends out stolons

Pores in the leaf formed by two guard cells

The blade position relative to the petiole where the midrib or midnerve of the blade continues in a straight line with the petiole, Ex. B. cucullata

Having harsh, stiff, straight, short hairs, bristle-like in harshness

The slender stalk of a pistil connecting the stigma to the ovary View Illustration

Prefix meaning almost or nearly

Having very slight marginal incisions or indentations, almost entire

A taxonomic category within species, where there may be a few morphological or genetic distinctions within the same species and a big difference in their geographic distribution. Its taxonomic rank is between species and variety

The material on which a plant lives, the soil or rock or sphagnum moss

Awl-shaped; tapering to a point

Juicy; fleshy; soft and thickened

Somewhat woody

Stems that are woody at the base that survive from year to year, with herbaceous distal portions

With longitudinal grooves

Above the base

Above ground; above the soil

Divided into similarly identical or mirror-image parts; near repetition of the pattern element either by reflection or rotation

Type of branching pattern where one branch develops more strongly than the other, resulting in the stronger branches forming the primary shoot and the weaker branches appearing laterally
