Overview

Hydrus Constuprula, better known by its colloquial name cockvine, is a mobile, parasitic, invasive, troglophile plant species native to Myrellion. It is endemic to large parts of the Myrellion underground, a status acknowledged by both sides of the on-going Myr conflict to be a result of its historical use as a biological weapon. A Class A non-sentient species, it is illegal for it to be transported or for individuals seeded by it to travel outside Myrellion.

Growth Cycles and Physiology

At “birth” cockvine seedlings resemble short, thick, green snakes with a grasping, anemone-like hand at one end and a slit, blunt purple head of variable shape at the other. The hand end is remarkable for its stem cell-like versatility – whilst it functions primarily as a catcher and mouth for the cockvine seedling, it not only acts as the beginning of its root system once it enters adulthood but it can also be used to actively splice itself not just to other cockvines but to animal life as well.

Aside from the rings of flexible, fibrous muscle that they retain throughout their lives, cockvines are seeded with a huge reserve of fructose-based energy which allows them to move swiftly away from their place of origin. During this stage of their life cockvines show a snake-like aversion to large sapient creatures, actively avoiding them except in certain circumstances (see parasitism below). They do however have a ravenous attitude towards life of a similar size to it and during this, their most mobile period of existence, hunt and eat as much food as they can in preparation for the dramatic growth stages ahead. Cockvine seedlings are omnivorous and will consume almost anything, which is cited as a key reason for its over-reaching success on Myrellion.

Like most herbaceous life cockvines react to light and moisture and, once an infant cockvine has consumed enough, it will seek out a dark, moist place to germinate. They are particularly fond of deep, narrow crevices, as these are ideal for the purposes of their adult selves. Here the cockvine buries its hand end into the earth and proceeds to branch out a considerable root system. The stem of the plant thickens and then sprouts thick vines, similar in appearance to its infant state but far longer and stronger. Large, successfully rooted cockvines have the ability to attract less fortunate infants; these may choose to graft themselves symbiotically to it in order to provide one more tentacle to the alpha cockvine, thus increasing the overall chances of the creature successfully snagging prey. An adult cockvine can have as many as twenty appendages, each up to thirteen feet in length.

Predatory Habits and Breeding

When ready to feed or mate adult cockvines extend tentacles out of their burrow, laying them still on the ground, relying on the dark of their chosen habitat and the swiftness of their grab to surprise prey. Cockvines are sensitive to vibration and express two different behaviors based on the size of an animal approaching its burrow. Smaller creatures – observational data suggests the upper bound for this category is Terran dog-sized animals - are swept straight into the crevice and, if they cannot escape in time, are slid into a pit of digestive juices below the main stem.

Bigger creatures are regarded as potential mates. Once a creature in this category has been induced into its burrow a cockvine will attempt to immobilize it with its tentacles. Cockvine tentacles sweat an oily substance and seep a pungent herbal semen from their tips in the presence of potential mates; this has a muscle-relaxing, aphrodisiac effect which in the close confines of a cockvine burrow is described as overpowering. Once a victim has been incapacitated the cockvine mates with it vigorously in every way it possibly can. Although they are only capable of inseminating functioning wombs, cockvines cannot discriminate between different entrances on a mate and simply seek to seed every hole as thoroughly as they can. Once it has finished, the cockvine carefully discharges the victim from its burrow and then retracts itself.

After insemination en utero cockvines only take around a week to come to term; litter sizes vary between 8 and 20. In itself the task of birthing them is described as extremely pleasurable, however mating with and bearing cockvines has been known to cause several side effects, including increased vaginal and anal wetness as well as outright contraction of cockvine parasitism.

Parasitism

Because of the specificity of location the seedlings need in order to germinate it is not at all possible for every individual cockvine to find an ideal place or stockpile enough energy to enter adulthood. The species has found a striking way of surmounting this difficulty, thanks to its hand end’s ability to bind itself not just to adult cockvines but to other creatures as well.

当肉棒藤幼苗错过了能够成功扎根的阶段，或察觉自己最好尝试嫁接到更有希望的生命体上时，这一过程便会发生。采取这种方式的肉棒藤通常会寻找同种的首领，把自己绑定上去；不过，只要生物足够大、能支撑它，并且愿意接受或来不及阻止，它也完全可以与任何生物结合。无论哪种情况，嫁接后的肉棒藤都会接入宿主的神经系统，并放弃大部分自身控制权，让大型生物能够像使用自己的附肢一样感知和操纵寄生体。不过，肉棒藤仍会保留精液囊和繁殖本能，偶尔甚至能用繁殖欲压倒宿主，让自己有机会把种子传播到远超原本范围的地方。与成年个体交配也被报告会导致肉棒藤寄生。

History

Hydrus Constuprula originates from the small continent of Irskand, and was discovered and classified by the former Red Myr nation of Harokees circa three hundred years ago. A bleak and inhospitable place even by Myrellion standards, the plant form had evolved to suit Irskand and was not particularly widespread. Harokees was at this time locked in a violent dispute with the Gold Myr over the relatively untouched landmass of Undandin; seeing its potential to disrupt Gold attempts to cultivate the Undandin fungus fields, the Red military approved cockvine’s covert release into Gold territory. The species duly exploded in population, spreading well beyond Undandin to infect virtually every corner of the Myrellion underground, despite a number of poorly coordinated joint efforts on the part of the Myr to wipe it out.

The internecine warfare between both species of Myr, the Nyrea, and the subsequent movement of peoples, breakdown of infrastructure and land wastage has only increased cockvine’s spread. The plant is also recorded as being used by both sides of the Myr conflict as a form of sadistic punishment on prisoners of war; once a kept plant has finished with captives they are released deep in their home territory, with the explicit hope of their offspring spreading chaos there. This practice is expressly forbidden by international law.
