terminal -- Located at the end (the tip or the apex).

petiolate -- a leaf that has a stem. A sessile leaf has no stem.

oblanceolate -- top wider than bottom

capsule -- a type of simple, dry fruit produced by many species of flowering plants. In most cases the capsule splits apart to release seeds.

A perennial plant lives and blooms for many years.

cauline leaves -- leaves growing on a stem and especially on the upper part.

villous -- Clothed with long, soft, unmatted hairs.

A spike is an unbranched, indeterminate inflorescence in which the flowers are without stalks.

serrate -- toothed with asymmetrical teeth pointing forward; like the cutting edge of a saw.

An entire leaf has smooth edges. Not toothed or lobed.

Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom.

reflexed -- bent sharply back or down.

basal -- at the base, situated or attached at the base.

fruit -- any seed-bearing structure in flowering plants. It is formed from the ovary after flowering.

style -- This is a long and thread-like structure that connects the stigma with the ovary. A flower may have a single style, or several of them.

sessile -- attached without a stalk. For example, a leaf that clasps the stalk. A petiolate leaf has a stalk.

biennial -- a plant which lives for two years, producing a basal rosette of leaves the first year and a full plant, flower, and seed the second year followed by the death of the entire plant at the end of the second year.

A herb is a plant whose stems die back to the ground in the winter.

lanceolate -- Lance-shaped. Long, wider in the middle.

oblong -- Having an elongated form with somewhat parallel sides. Rectangular.
