Garden terms are often useful, though they may not always be scientifically correct. We all knew one time what we meant by Scarlet geraniums, though many of them had gone on to other colors besides scarlet; but the botanist showed that there was no difference between geranium and pelargonium, and at once we had no more scarlet geraniums; they were Zonale pelargoniums, though many had no more dark zones to the leaves than in former times there were all scarlets among the colors. Trouble is again experienced, and now we note in England they go by the name of market pelargoniums.
