People were surprised, and a little disgusted, to learn that the species was carnivorous, and that the flies and other insects caught in the cups were actually digested by the sticky substance there. We in temperate zones were not ignorant of insectivorous plants, but we were unaccustomed to finding them outside special hothouses, and apt to consider them as in some way slightly indecent, or at least improper. But actually alarming was the discovery that the whorl topping a triffid’s stem could lash out as a slender stinging weapon ten feet long, capable of discharging enough poison to kill a man if it struck squarely on his unprotected skin.
As soon as this danger was appreciated there followed a nervous smashing and chopping of triffids everywhere, until it occurred to someone that all that was necessary to make them harmless was the removal of the actual stinging weapon. At this, the slightly hysterical assault upon the plants declined, with their numbers considerably thinned. A little later it began to be a fashion to have a safely docked triffid or two about one’s garden. It was found that it took about two years for the lost sting to be dangerously replaced, so that an annual pruning assured that they were in a state of safety where they could provide vast amusement for the children.
In temperate countries, where man had succeeded in putting most forms of nature save his own under a reasonable degree of restraint, the status of the triffid was thus made quite clear. But in the tropics, particularly in the dense forest areas, they quickly became a scourge.
The traveler very easily failed to notice one among the normal bushes and undergrowth, and the moment he was in range the venomous sting would slash out. Even the regular inhabitant of such a district found it difficult to detect a motionless triffid cunningly lurking beside a jungle path. They were uncannily sensitive to any movement near them, and hard to take unawares.
Dealing with them became a serious problem in such regions. The most favored method was to shoot the top off the stem, and the sting with it. The jungle natives took to carrying long, light poles mounted with hooked knives, which they used effectively if they could get their blows in first—but not at all if the triffid had a chance to sway forward and increase its range by an unexpected four or five feet. Before long, however, these pikelike devices were mostly superseded by spring-operated guns of various types. Most of them shot spinning disks, crosses, or small boomerangs of thin steel. As a rule they were inaccurate above about twelve yards, though capable of slicing a triffid stem neatly at twenty-five if they hit it. Their invention pleased both the authorities—who had an almost unanimous distaste for the indiscriminate toting of rifles—and the users, who found the missiles of razor-blade steel far cheaper and lighter than cartridges, and admirably adaptable to silent banditry.
Elsewhere, immense research into the nature, habits, and constitution of the triffid went on. Earnest experimenters set out to determine, in the interests of science, how far and for how long it could walk; whether it could be said to have a front, or could perform its march in any direction with equal clumsiness; what proportion of its time it must spend with its roots in the ground; what reactions it showed to the presence of various chemicals in the soil; and a vast quantity of other questions, both useful and useless.
The largest specimen ever observed in the tropics stood nearly ten feet high. No European specimen over eight feet had been seen, and the average was little over seven. They appeared to adapt easily to a wide range of climate and soils. They had, it seemed, no natural enemies—other than man.
But there were a number of not unobvious characteristics which escaped comment for some little time. It was, for instance, quite a while before anyone drew attention to the uncanny accuracy with which they aimed their stings, and that they almost invariably struck for the head. Nor did anyone at first take notice of their habit of lurking near their fallen victims. The reason for that became clear only when it was shown that they fed upon flesh as well as upon insects. The stinging tendril did not have the muscular power to tear firm flesh, but it had strength enough to pull shreds from a decomposing body and lift them to the cup on its stem.
There was no great interest, either, in the three little leafless sticks at the base of the stem. There was a light notion that they might have something to do with the reproductive system—that system which tends to be a sort of botanical glory-hole for all parts of doubtful purpose until they can be sorted out and more specifically assigned later on. It was assumed, consequently, that their characteristic of suddenly losing their immobility and rattling a rapid tattoo against the main stem was some strange form of triffidian amatory exuberance.
