Perfect and Imperfect

The terms perfect and imperfect as pertaining to flowers relates to their sexuality. Flowers are the sexual organs of a plant, and they may contain male (stamens), female (pistils), or both parts. A plant is said to be perfect if it possesses both male and female equivalent parts. If a flower has only male, or only female structures, it is said to be imperfect.

De la Biblia, señalar dos lecciones espirituales en las que los escritores utilizan las flores para las ilustraciones.

Jesus spoke of the futility of worry:

Matthew 6:28-30

"And why do you worry about clothes? See how the lilies of the field grow. They do not labor or spin. 29Yet I tell you that not even Solomon in all his splendor was dressed like one of these. 30If that is how God clothes the grass of the field, which is here today and tomorrow is thrown into the fire, will he not much more clothe you, O you of little faith? - NIV

Nombrar y decir ocho plantas venenosas, señalando la parte de la planta que es venenosa.

Poison Hemlock

Poison Hemlock

Nombre binomial: Conium spp. Descripción: Poison Hemlock is a herbaceous biennial plant which grows between 1.5–2.5 m tall, with a smooth green stem, usually spotted or streaked with red or purple on the lower half of the stem. The leaves are finely divided and lacy, overall triangular in shape, up to 50 cm long and 40 cm broad. The flowers are small, white, clustered in umbels up to 10–15 cm across. The plant is often mistaken for fennel, parsley or wild carrot although the characteristic stem hairs of the wild carrots are missing. The Conium root is fleshy, white and often unbranched and can be mistaken for parsnip. When crushed, the leaves and root emit a rank, unpleasant odour often compared to that of parsnips. Dónde se encuentra: Poison Hemlock is native to Europe and the Mediterranean region, and to southern Africa, but has been introduced and naturalized in many other areas, including much of Asia, North America and Australia. Poison hemlock is often found on poorly drained soils, particularly near streams, ditches, and other surface water. ADVERTENCIA: All plant parts are poisonous but once the plant is dried, the poison is greatly reduced, however not gone completely. Hemlock is also known as "poison parsley" or "spotted parsley".
