If p > 0, the parabola opens to the right and if p < 0 the parabola opens to the left. The equations we have just established are known as the standard equations of a parabola. A standard equation always implies the vertex is at the origin and the focus is on one of the axes.
Euphorbias are on all the toxic plant lists and everyone is familiar with the hazards of Poinsettias.here is some discussion of severe toxic principles of Tylecodons I did not understand as these are in no way related to Euphorbias or in the Euphorbia family.

Some of the most frequently isolated molds and fungi in this study were: Alternaria alternata, Ophiostoma piceae, Ophiostoma piliferum, and Nectria cinnabarina. Some species of Basidiomycota are pathogens for both plants and animals.However, they are not all harmful. Some form symbiotic relationships with the roots of vascular plants. The bastidiomycota help the plants obtain nutrients from the soil, and in return recieve sugars produced through photosynthesis.Bastidiomycota also form symbiotic relationships with insects.owever, they are not all harmful.
