49 A rose grows from a seed. With the help of warm weather and water, a shoot pushes up from the ground and the plant grows bigger. Its thorns help it hang on to whatever surfaces are around it. Buds appear that will become flowers. Flowers are reproduction centers for plants. Until the bud is developed enough for reproduction, it's covered by green leaf-life structures called sepals.

50 When the sepals have opened, the flower shows forth. Flowers have petals with bright colors and sweet scents to attract insects and animals (such as birds) as pollinators. Roses also produce nectar--a sugary liquid pollinating animals like as food. Flowers produce pollen--tiny grains needed to make seeds. Pollen sacs, called anthers, sit on top of filaments in the flower's middle. As insects or animals feed on the nectar, pollen sticks on to them. When they go to the next flower, the pollen rubs onto it, starting pollination. The pollen is trapped by another flower's stigma, a sticky surface at the top of the pistil, the part of the flower containing an ovule. A tube called a style holds up the stigma. The style leads down to the ovary that contains the ovules. Fertilized by pollen, the ovule becomes a seed.

51 Because the flower has done its job-- reproducing the plant through pollination--it begins to wither. Its petals begin to fall off, and it loses its scent. The top of a flower's stem, the receptacle, swells from seeds beginning to grow inside of it. When the receptacle swells to its fullest and turns red, it is called a rose hip. Rose hips are eaten by small animals and birds, who carry rose hips away from the plant. The seeds come out in animal droppings, sometimes landing on soil where they grow into new rose plants.

52 Cashew Nut Tree The plant's sap from bark, leaves and particularly the nutshell can within one day cause painful skin alterations which resemble second-degree burns. This sap is brown and oily and becomes black when exposed to the air. The fumes which emerge from roasting the nuts are skin-irritating and can even lead to blindness.

53 Croton The hairs of the plant cling to the hands when touched. The latex (a milky liquid in certain plants that coagulates on exposure to air) has caused eczema in some gardeners. Dumb Cane Freshly cut parts are very skin irritating. After one day rashes develop. Irreversible skin damage is possible.

54 Cow Itch The hairs act as a mechanical-chemical skinirritant. If only one of the hairs gets on the skin, itch can already be felt. Reddening of the skin occur a few minutes after contact with the hairy parts of the plant. The cow-itch hairs break off easily and can contaminate clothes or other objects. If the hairs get in the eye, blindness is likely.

55 Manchineel On the skin the sap induces a violent burning sensation, together with inflammations and vesicles or rashes with subsequent abrasion of the epidermis. If a small drop of the caustic latex or the smoke of the burning tree gets into the eyes, blindness can be the result. Even raindrops falling from a Manchineel tree can cause skin damages and severe eye irritation.

87 I will be as the dew unto Israel: he shall grow as the lily, and cast forth his roots as Lebanon. Hosea 14:5 And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin. Matthew 6:28

88 I am the rose of Sharon, and the lily of the valleys. Song of Solomon 2:1 The wilderness and the solitary place shall be glad for them; and the desert shall rejoice, and blossom as the rose. Isaiah 35:1
