The Gods of Mars by Edgar Rice Burroughs (All-Story, January-May 1913)

DESCRIPTION: "Odd, grotesque shapes they were; unlike anything that I had ever seen upon Mars, and yet, at a distance, most manlike in appearance. The larger specimens appeared to be about ten or twelve feet in height when they stood erect, and to be proportioned as to torso and lower extremities precisely as is earthly man. Their arms, however, were very short, and from where I stood seemed as though fashioned much after the manner of an elephant's trunk, in that they moved in sinuous and snakelike undulations, as though entirely without bony structure, or if there were bones it seemed that they must be vertebral in nature...As he approached quite close to me I obtained an excellent view of him, and though I was later to become better acquainted with his kind, I may say that that single cursory examination of this awful travesty on Nature would have proved quite sufficient to my desires had I been a free agent. The fastest flier of the Heliumetic Navy could not quickly enough have carried me far from this hideous creature. Its hairless body was a strange and ghoulish blue, except for a broad band of white which encircled its protruding, single eye: an eye that was all dead white--pupil, iris, and ball. Its nose was a ragged, inflamed, circular hole in the centre of its blank face; a hole that resembled more closely nothing that I could think of other than a fresh bullet wound which has not yet commenced to bleed.
Below this repulsive orifice the face was quite blank to the chin, for the thing had no mouth that I could discover. The head, with the exception of the face, was covered by a tangled mass of jet-black hair some eight or ten inches in length. Each hair was about the bigness of a large angleworm, and as the thing moved the muscles of its scalp this awful head-covering seemed to writhe and wriggle and crawl about the fearsome face as though indeed each separate hair was endowed with independent life. The body and the legs were as symmetrically human as Nature could have fashioned them, and the feet, too, were human in shape, but of monstrous proportions. From heel to toe they were fully three feet long, and very flat and very broad. As it came quite close to me I discovered that its strange movements, running its odd hands over the surface of the turf, were the result of its peculiar method of feeding, which consists in cropping off the tender vegetation with its razorlike talons and sucking it up from its two mouths, which lie one in the palm of each hand, through its arm-like throats. In addition to the features which I have already described, the beast was equipped with a massive tail about six feet in length, quite round where it joined the body, but tapering to a flat, thin blade toward the end, which trailed at right angles to the ground. By far the most remarkable feature of this most remarkable creature, however, were the two tiny replicas of it, each about six inches in length, which dangled, one on either side, from its armpits. They were suspended by a small stem which seemed to grow from the exact tops of their heads to where it connected them with the body of the adult."

NOTES: The Plant Men live in the Valley Dor along the River Isis where all the dead of Mars are delivered, supposedly to paradise. The plant men, of course, eat them. Burroughs may have been commenting on the Indian custom of placing the dead in the Indus River.

HISTORY: The Plant Men of Mars are the first vegetable species in a maor Science Fiction work. The next would be the Centaurians of Murray Leinster's "Proxima Centauri" twenty-two years later.
